Overview
The IBM TotalStorage Virtual Tape Server (VTS) Model B10 is an entry
level model designed to be a highly scalable, sharable, high-performing
storage solution for most, if not all, of your sequential files. The
Model B10 is intended to:
- Bring efficiency to the tape operation
- Reduce batch windows
- Reduce the cost of tape operations
- Support disaster recovery
The Model B10 accomplishes this by integrating high-capacity tape,
high-performance tape drives, high-performance disk storage, and RISC
technology to form a storage hierarchy managed by robust storage
management firmware with advanced capability. The internal storage
hierarchy consists of a RISC controller, SSA RAID-5 disk, 3590 Tape
Drives, and high-function storage management software to manage the
storage hierarchy. The external image appears as a maximum 64 virtual
3490E tape drives and 250,000 automated tape volumes each with a maximum
capacity of 2.4 GB (assuming 3 to 1 compression). All tape volumes are
initially stored in a tape volume cache contained in disk storage for
fast access, then written to tape. Tape volume cache contents are
managed to keep recently accessed volumes in the cache to minimize mount
delays. Cache management is provided to allow expedited deletion from
the cache of those volumes not expected to be read after creation.
Advanced policy management is provided to allow a storage
administrator to control the following:
- Media selection
- Collocation of logical volumes
- Dual logical volume copy creation
- Expedited deletion from tape volume cache
- Peer-to-Peer VTS copy mode
Dynamic policy selection is provided by OS/390 and z/OS DFSMS using
storage group, storage class, and management class policies.
The Peer-to-Peer Copy feature combined with Virtual Tape Controllers
(VTC) allows interconnection of two VTSs to provide a solution with no
single points of failure. Incorporating the Model B10 in a PtP VTS
configuration provides flexible component placement to facilitate 24 x 7
processing requirements and a solution for remote backup and recovery.
The Peer-to-Peer Copy feature supports use of the VTS with IBM's business
continuance solution such as the Geographically Dispersed Parallel
Sysplex offering or your own disaster recovery solution.
The Model B10 provides a variety of channel attachments, disk storage
capacities, tape drive attachments, advanced features, and management
options.

Server Attachments
VTS provides attachment to various servers using either FICON, ESCON,
or SCSI adapters. Each of these adapters provide on board LZ1
compression to improve performance and increase the effective capacity of
the tape volume cache. Virtual volumes can be shared between servers
using any of the following attachment features.
- FICON
You can attach a VTS Model B10 to native FICON channels in systems
such as:
- zSeries 800 and 900 Servers
- IBM 9672 Enterprise G5 or G6 Servers
A Model B10 with the FICON Enablement feature(#3000) can be configured
with either two or four FICON channels. If two FICON channels are
configured then two ESCON channels can also be configured. Each Long
Wave FICON Channel (#3415) feature and Short Wave FICON Channel (#3416)
feature provides a single FICON adapter and can be attached directly to a
server or through one IBM 2042 McData ED-6064 Enterprise Fiber Channel
Director or IBM 2032 INRANGE FC/9000 Fibre Channel Director. Each
attachment feature provides 128 logical channels. Long and short
wavelength features can be intermixed in any combination to meet your
needs.
FICON attachment features can provide a 75% or more increase in peak
write performance compared to a Model B10 configuration with 4 ESCON
channels. They also can extend the allowable server to VTS attachment
distance up to 100 km. FICON attachment can enable you to reduce the
number of channels, director ports, and communication fibre cables. The
most obvious benefits of FICON connectivity are increased per channel
bandwidth and greater simplicity of the channel fabric. The increased
speed available with FICON connections can allow customers to collapse
existing ESCON channels into FICON channels at the rate of approximately
4:1, or in some cases more if ESCON channel utilizations are relatively
low.
Greater simplicity of configuration is achieved, because the FICON
architecture allows more devices per channel (up to 16,384) and more
Logical Subsystems (LSS) per channel to match the increased channel
bandwidth. Single stream sequential operations may experience a
significant improvement in throughput (as much as 2X), so that elapsed
times for key batch, data mining, or dump operations can substantially
improve. This can help provide relief for customers whose batch or file
maintenance windows are constrained today.
Finally, significant performance advantages can be realized by those
customers who access their VTS subsystems remotely. FICON reduces or
eliminates data rate propagation delay for distances up to 100 km for
both read and write operations by using enhanced data buffering and
pacing schemes.
- ESCON
You can attach a VTS Model B10 or a PtP VTS configured with VTS Model
B10s to native ESCON channels in systems such as:
- zSeries 800 and 900 Servers
- IBM 9672 Enterprise Servers
- ES/9000 Servers
- ES/3090 Servers
The Extended Performance ESCON Channels feature (#3412) provides two
independently operating extended performance ESCON channel adapters.
Each ESCON channel provides 64 logical channels and can be attached
through the IBM 9032 ESCON director. Directors can extend the distance
between servers and VTS up to 26 km. An IBM 2029 can extend the distance
between a server and VTS to 75 km. (Refer to Remote Data
Copying for additional information)
- SCSI
You can attach a VTS Model B10 to servers such as:
- pSeries
- RS/6000
- SUN Solaris
- HP/UX
- Intel Windows NT or 2000
The SCSI Host Attachment feature (#3422) permits open systems host
attachment through industry-standard SCSI busses. Each SCSI Host
Attachment provides two SCSI bus attachments and includes data
compression compatible with the ESCON High Performance Option. Each bus
provides up to 16 virtual devices and emulates automated 3490E tape
drives. Each feature supports a maximum of 16 virtual devices. The
feature supports attachment to the SCSI-2 standard interface on selected
servers.
The SCSI Host Attachment feature allows sharing of the VTS resource
between mainframes and open systems. Virtual volumes can be serially
shared between mainframes and open systems. With the virtual capability
of a VTS, one or more SCSI attached virtual devices can be dedicated to
an AIX, UNIX, or Intel server. Selected servers with Host Bus Adapters
can use the IBM 2108 SAN Data Gateway and IBM 2109 SAN Fibre Switch to
attach to a VTS. SCSI Host attachment is mutually exclusive with the
Peer-to-Peer Copy (#4010) and FICON Enablement (#3000) features.
Disk Storage
Integrated disk storage features configured as RAID 5 arrays are used
to provide the Tape Volume Cache for temporary storage of virtual
volumes. All virtual tape access is through the Tape Volume Cache.
Multiple virtual volumes are stored in the Tape Volume Cache and retained
in it as long as possible to provide fast access for future tape mounts.
The contents of the cache are managed with a least recently used
algorithm which can be influenced by user defined policies. New or
updated virtual volumes are quickly copied to tape so that space for
newly created volumes or recalled volumes does will not need to wait for
copy to tape prior to reclamation of the space occupied on disk by older
unreferenced volumes. The disk storage features are:
- 144/216 GB Disk Storage
The 144/216 GB Disk Storage feature (#3704) provides 216 GB of useable
disk storage capacity for tape volume cache. With built in data
compression (3:1) the effective capacity is 648 GB.
- 288/432 GB Disk Storage
The 288/432 GB Disk Storage feature (#3705) provides 432 GB of useable
disk storage capacity for tape volume cache. With built data compression
(3:1) the effective capacity is approximately 1.3 TB.
Advanced Function
The Advanced Function Feature (#4000) provides host controlled
functions to further exploit the use of tape and disk subsystems in the
virtual tape server. These functions are:
- Tape Volume Cache Management
- Import/Export
The device driver support for SCSI Host Attachment (#3422) does not
include the support for the Advanced Function (#4000).
Simple Tape Volume Cache Management
DFSMS policy management can be used to assign virtual volumes to
preference groups that further control which volumes are deleted from
cache after they are copied to tape when space is needed in the cache.
One preference group (the default) will be managed using the existing
least recently used algorithm for deletion from cache. The volumes
associated with the second preference group by DFSMS will be preferred
for making space available in the tape volume cache for scratch volumes
and recalled volumes before those in the default preference group. The
DFSMS Storage Class Initial Access Response Time (IART) parameter can be
used to specify which of the two preference groups will be used. The
cache management capability of the Advanced Function feature can be used
with VTSs included in a Peer-to-Peer VTS.
Import/Export
VTS data portability is provided by a set of functions called Import
and Export. The Import and Export functions allow you to move data
between VTSs without having to copy the logical volumes back through the
host channels or lose the VTS benefits of volume stacking, which can
exploit the storage capacity of the 3590 cartridge. Exported logical
volumes are not accessible any longer in the VTS after the Export, and
become accessible in a VTS after an Import. The Import/Export capability
of the Advanced Function feature cannot be used with VTSs in a
Peer-to-Peer VTS configuration.
Advanced Policy Management
The Advanced Policy Management features (#4001 and #4002) allow you to
pool virtual volumes, maintain a second virtual volume copy, and control
the Peer-to-Peer copy mode for virtual volumes. Volume pooling allows
you to group volumes to different media and manage multiple media types.
Selective dual copy can improve data availability of critical data with
automatic recovery. Selective dual copy mode control can improve the
availability of critical volumes in a PtP VTS configuration. The
Advanced Policy Management includes the capability of the Advanced
Function feature (#4000) and includes the Simple Tape Volume Cache
Management and Import/Export functions described above, plus the
following additional capabilities:
Tape Volume Cache Management (Outboard Policy Management
Controlled)
DFSMS policy management can be used to assign virtual volumes to
preference groups that further control which volumes are deleted from
cache after they are copied to tape when space is needed in the cache.
One preference group (the default) will be managed using the existing
least recently used algorithm for deletion from cache. The volumes
associated with the second preference group by DFSMS will be preferred
for making space available in the tape volume cache for scratch volumes
and recalled volumes before those in the default preference Group.
Storage class names and their associated preference group are defined in
the 3494 using the IBM TotalStorage Enterprise Tape Library Specialist.
DFMSS can be used to provide the appropriate storage class name for a
volume to the VTS.
Physical Volume Pooling (Outboard Policy Management
Controlled)
The objective of volume pooling is to group logical volumes together
on the same group of tape media. If DFSMS is deployed, then logical
volumes can be assigned to a pool at data creation time, otherwise
logical volumes can be assigned to pools when they are defined to the
Library Manager. They will retain that definition until changed by the
storage administrator or by DFSMS.
A pool can have an initial and a secondary media type so that logical
volumes can be initially placed on shorter media (J cartridges) and when
space reclamation runs, they will be placed on longer length tape. In
addition, each pool can have its own reclamation threshold. Physical
volumes can be moved between pools. Stacked volumes can be assigned to a
pool by the storage administrator or dynamically obtained from and
returned to a common scratch pool.
Selective Dual Copy (Outboard Policy Management Controlled)
Dual copy allows selective creation of a second copy of a logical
volume on separate media from the primary copy and maintains the
separation whenever either logical volume is moved by reclamation. If a
volume is recalled and the primary copy can not be used, then the
secondary copy, if it exists, will be used for the recall. Thus, dual
copy can improve data availability. Dual copy is defined by the
management class policy by assigning a secondary storage pool.
Peer-to-Peer Copy Mode Control (Outboard Policy Management
Controlled)
Peer-to-Peer copy mode control allows selective use of immediate and
deferred copy mode for logical volumes. Use of deferred copy provides
higher peak performance, so selective use of immediate copy mode for
important data can result in higher peak performance. Copy mode control
is a management class policy attribute.
The device driver support for SCSI Host Attachment (#3422) does not
include the support for the Advanced Function (#4000) or Advanced Policy
Management (#4001 and #4002). The Advanced Policy Management features
have the following prerequisites:
- Four or more 3590 tape drives associated with the VTS
- If the Import/Export functions are to be used, the 10-Cartridge or
30-Cartridge Convenience Input/Output Station feature must be installed
- A minimum cache configuration of 216 GB
Disk Capacity Feature Requirements
Disk Capacity Advanced Policy
(uncompressed) Disk Features Management Features
-------------- -------------------- --------------------------
Up to 250 GB (1)#3704 or (3)#3702 #4001
Up to 500 GB (1)#3705 or (4)#3702 #4001, #4002
The Advanced policy management feature may be installed on both VTSs
of a PtP VTS configuration. The Import/Export function is inoperable
when the Peer-to-Peer copy feature is installed. Use of volume pooling
or dual copy may result in a need to increase tape volume cache capacity
and the number of 3590 tape drives. Use of dual copy may reduce the
bandwidth available to host servers during peak periods of server
activity. The device driver support for SCSI Host Attachment (#3422)
does not include the support for the Advanced policy management (#4001).
Peer-to-Peer Copy
Peer-to-Peer Copy features (#4010 and #4011) and Virtual Tape
Controllers (VTC) enable interconnection of two VTS to form a
Peer-to-Peer VTS (PtP VTS) with no single points of failure. The
components of a PtP VTS can be physically separated to provide a disaster
backup/recovery solution. Peer-to-Peer Copy (#4010) is mutually
exclusive with SCSI Host Attachment (#3422).
The PtP VTS configuration appears to host applications as a single VTS
and does not typically require change to tape applications or JCL. ESCON
or FICON links are used for the interconnection, which allows the
physical separation of the VTS at extended distance. VTC copy services
automatically replicate all volumes in each VTS to provide a virtual tape
subsystem suited for disaster backup for tape data. Each of the VTSs in
a PtP VTS continues to operate during scheduled or unscheduled service of
the other VTS. Two modes of copy services operation are provided by the
VTCs:
- Immediate Copy - creates a copy in the companion connected VTS prior
to completion of a Rewind Unload command and provides the highest level
of protection of your data available with the VTS
- Deferred Copy - schedules creation of a copy in the companion
connected VTS after receipt of a Rewind Unload command as activity
permits
PtP VTS Components
The interconnected components of a PtP VTS configuration are:
- 3494 Model B10 or B18 VTS - VTS with the Peer-to-Peer Copy feature
- 3494 Model AX0 Virtual Tape Controllers - provide host ESCON
attachment and interconnection of two VTSs
- 3494 Model CX0 Virtual Tape Frame - holds two or four 3494 Model AX0
Virtual Tape Controllers
- 3494 Model CX1 Virtual Tape Frame - holds two or four VTCs (two or
four VTC features on the Model CX1, or two Model AX0s and two Model CX1
VTC features)
A pair of interconnected Model B10 VTSs in a PtP VTS configuration
will appear to host processors as a single image VTS which will have:
- Four fully configured independent "3490E" tape subsystems with 16
tape drives each (64 virtual tape drives maximum)
- Up to 8 ESCON channels
- Up to 2.5 TB (with 3:1 compression) of disk storage
- A maximum capacity of 250,000 logical volumes
A VTS with the Peer-to-Peer Copy features is an independently
operating distributed server node in a PtP VTS configuration. A VTS with
the Peer-to-Peer Copy features incorporates all the functional capability
of the VTS itself except for the following:
- SCSI host attachment
- Export/Import capability of Advanced Function and Advanced Policy
Management features.
The VTS incorporates channel commands to support large block transfers
of compressed logical volumes to and from VTCs. Functions allow the VTCs
to maintain copy synchronization of the two VTSs and provide expedited
deletion of redundant logical volume copies from the tape volume cache.
Remote Data Copying
The components of the PtP VTS can be physically separated to provide
remote copy of virtual volumes. One of the VTSs with its companion 3494
would be in one location and the other VTS with its companion 3494 in
another location. The required four VTCs can be flexibly placed between
the two locations as shown below:
Configurations Location A Location B
------------------------- ---------- ----------
Configuration 1 (B10/B18) 2 VTCs 2 VTCs
Configuration 2 (B10/B18) 4 VTCs 0 VTCs
Configuration 3 (B10/B10) 2 VTCs 2 VTCs
Configuration 4 (B10/B10) 4 VTCs 0 VTCs
ESCON directors, Fibre Channel Directors, or Dense Wave Division
Multiplexors (DWDM) can be used to extend the maximum distance between
components as shown in the following table:
ESCON With
ESCON DWDM (1) FICON
----- ---------- ------
Host Server to VTC 43 km 75 km 100 km
VTC to VTS 26 km 50 km 100 km
Note: (1) The maximum end-to-end distance of the host system to VTC ESCON
interface, including the DWDM pair length, is 75 km. The maximum
end-to-end distance of the VTC to VTS ESCON interface, including the
DWDM pair length, is 50 km.
The VTS FICON attachments support 2-Gbps link speed when attached to a
zSeries server, or an appropriate FICON/FC switch, with 2-Gbps FICON
features and the appropriate levels of software to utilize the 2-Gbps
capability. Extended distance connections can be provided by channel
extenders (virtually unlimited distance) certified for use by providers
with a PtP VTS ESCON configuration.
It is highly recommended that both VTSs be configured with the same
disk storage capacity. Each of the VTSs in a PtP VTS configuration
continues to operate during scheduled or unscheduled service of the other
VTS.
Geographically Dispersed Parallel Sysplex (GDPS) Control
The PtP VTS configuration is extended to allow the GDPS service
offering to include tape data in its management of data consistency and
integrity across sites. A new I/O VTS selection option is provided
especially for use with GDPS such that all virtual volumes are processed
from a primary VTS, and a copy is stored on the secondary VTS. Control
capability has been added to allow GDPS to 'freeze' copy operations so
that tape data consistency can be maintained across GDPS managed sites
during a switch between the primary and secondary VTSs, and also provide
synchronization of system data sets such as catalogs, the tape control
database, and tape management databases with the PtP VTS after an
emergency switchover.
Expanded DFSMS Tape Library Application Interface
PtP VTS operations can now be user controlled through use of the
expanded DFSMS Tape Library Application Interface. You can now
dynamically control the copy mode of operation and I/O VTS selection
mode. Additional functions include enable/disable copy operation, and
query virtual drive and volume status. Users can tailor the control of
their PtP VTS by writing their own application program that exploits the
application interface.
Tape Specialists
Two specialists are available on the 3494 that enable you to monitor
and manage specific integrated library storage devices, the IBM
TotalStorage Enterprise Tape Library Specialist and the IBM TotalStorage
Peer-to-Peer Virtual Tape Server Specialist. They can provide
comprehensive status, capacity, and performance information to
efficiently monitor storage resources from any location within an
enterprise.
Tape Library Specialist
The Tape Library Specialist is a system-independent, web-based user
interface to the 3494 library manager, which enables you to monitor and
manage the library manager and attached Virtual Tape Servers from a
remote location.
Monitor capabilities will allow you to:
- View system summary
- View system activity
- View operator interventions
- View command queue
- View performance statistics
- View component availability
Management capabilities will allow you to:
PtP VTS Specialist
The PtP VTS Specialist is the web user interface used to view the
current status and configuration of the PtP VTS.
Monitor capabilities will allow you to:
- View PtP VTS status
- View PtP configuration
- View virtual drive activity
- View copy workload
- View logical volume status
Commonly used browsers such as Microsoft Internet Explorer or Netscape
Navigator can be used to view the information. Information applying to
all attached VTS systems will be available on a read-only basis and will
be updated periodically by the subsystems.
Reliability, Availability, and Serviceability (RAS)
The new controller helps bring availability features and functions to
the VTS Model B10. The dual power subsystem provides redundancy in case
of power supply failure. The controller and I/O drawer cooling
subsystems have two fans, which can be replaced concurrently with
operation. The I/O drawer isolates each adapter from other adapters and
the system busses so that operation can continue if an adapter fails.
Constant monitoring by the controller allows IBM service representatives
to diagnose many potential system malfunctions without interrupting
end-user operation.
TotalStorage Master Console
The IBM TotalStorage Master Console connects multiple Virtual Tape
Servers or Virtual Tape Controllers to a dedicated, private local area
network. Remote data monitoring of each VTS attached to the master
console is provided for early detection of unusual conditions. Summary
information is sent to IBM after monitoring is complete. Connection to
the master console is required with a VTS Model B10.
"Call Home" Service Support
The "Call Home" function, when activated, automatically opens a
service alert when a problem occurs with the VTS, VTC, or a Enterprise
3590 Model A60 or A50 Controller in an Enterprise Tape Library 3494. The
"Call Home" process can also be initiated by a user from the 3494 library
manager operator panel for those devices. A service representative can
be sent to the installation and status information can be transmitted to
the Support Center for problem evaluation. In addition, "Call Home"
allows these service alerts to be sent to a pager service so that
multiple people, including the customer, can be notified.

Product Positioning
| |
The IBM TotalStorage Virtual Tape Server (VTS) is a premier tape
solution for:
- Disaster backup
- Data consolidation
- Data protection
- Interoperability
It is designed to provide the following benefits:
- Reduced operating costs, such as:
- Power
- Maintenance
- Operations and support staff
- Reduced batch window
- Reduced floor space consumed by tape operations
- Improved operational quality
- Increased level of tape automation
- Improved tape data availability
- Fast access to data
- Cross server data sharing
- Remote dual copy for use with:
- GDPS
- Disaster backup and recovery
- Remote tape vault
VTS incorporates extensive self management capabilities consistent
with IBM eLiza project initiatives. Self management facilities include
self optimization, self configuration, self healing, self protection.
These capabilities can reduce the cost of a VTS solution, minimize the
impact of errors, and provide protection. A VTS can help improve the
efficiency of mainframe and open systems tape operations by efficiently
using disk storage, tape capacity, and tape speed, and by providing a
large number of tape addresses. Two models, the B10 and B20, provide a
wide range of configuration options to address the needs of small and
large customers. The VTS allows you to standardize on a single tape
technology across multiple diverse hardware and operating systems.
Elimination of heterogeneous tape technologies such as DLT, 8mm, or 4mm
tape should simplify operating procedures, allow data sharing, and reduce
the cost of growth. These benefits make VTS a suitable repository for
all your local and remote backups, and archival data. The VTS helps
support your business intelligence initiatives by allowing shared volume
access between mainframes and open systems platforms.
IBM continues to dramatically extend attachability, configurability,
and manageability of the VTS family. The new features and functions
included in the Model B10 and B20 VTSs help to extend your investment in
VTS, provide a growth path for a growing tape workload, and demonstrate
the value of the Seascape Architecture to provide timely features and
functions. The performance and capacity features provided with the VTS
allow placement of datasets in the VTS, which can eliminate direct use of
conventional tape devices.
The VTS has two separate features that you can use for disaster backup
and recovery:
- Peer-to-Peer Copy
The Peer-to-Peer Copy feature, an IBM solution for disaster recovery,
allows the VTS to operate in a PtP VTS configuration by interconnecting
two VTSs and automatically maintaining volume copies in both VTSs. This
option can improve your sequential file data availability and
recoverability. The redundant components of the PtP VTS can be
separated, thus making it an ideal solution for remote backup and
recovery. If you have, or plan to have, a GDPS operation, PtP VTS is an
ideal solution for the tape workload through its remote dual copy
capability. Alternatively, the entire PtP VTS can be used in a local
environment to improve data availability and recoverability.
- Import/Export
Volumes required for disaster backup can be exported from a
stand-alone VTS using the import/export facility of the Advanced Function
feature. These volumes can be stored remotely and entered into a
disaster recovery VTS using the import facility of the Advanced Function
feature.
The VTS uses disk storage and the unique performance and capacity of
the Enterprise 3590 Tape Drives to help reduce the total cost of
ownership of tape solutions for z/OS, OS/390, TPF, z/VM, VM/ESA, VSE/ESA,
AIX, Windows, and UNIX environments.

Technical Description
|
The IBM TotalStorage Virtual Tape Server (VTS) integrates IBM
TotalStorage Enterprise 3590 Tape Drives, a RISC-based controller, RAID
disk storage, and the IBM TotalStorage Enterprise Automated Tape Library
to provide a FICON, ESCON, and SCSI attached hierarchical storage
management system for multiple servers. The VTS provides the tape
control unit function for the virtual drives and the hierarchical storage
management function for management of the tape volume cache and the 3590
stacked volumes. The Model B10 VTS contains a RS/6000 symmetric
multiprocessing processor, server attachments, attachment of four to six
3590 Tape Drives, and IBM fault-tolerant RAID disk storage. It includes
up to four FICON channels, up to four ESCON channels, up to eight SCSI
bus attachments, support of up to 64 virtual tape drive addressing, and
up to 1.3 TB of disk storage capacity. The VTS is externally attached to
the Enterprise Tape Library with SCSI cables to 3590 Tape Drives in an
associated Model D12 Tape Drive Expansion Frame (or feature #5502). The
VTS is also attached via a LAN connection to the library manager in the
3494 Model L10, L12 or L14 Tape Library Base Frame.
PtP VTS Configuration
A VTS with the Peer-to-Peer Copy features is an independently
operating distributed server node in a PtP VTS configuration. The PtP
VTS configuration interconnects two VTSs with Virtual Tape Controllers
(VTCs) to provide both remote and local peer-to-peer copy capability
between two VTSs using ESCON connections. A pair of interconnected Model
B10 VTSs in a PtP VTS configuration will appear to host processors as a
single image VTS. The VTS incorporates channel commands to support large
block transfers of compressed logical volumes to and from the VTCs. It
will automatically create a copy of any newly created or updated volume
in either VTS transparently to customer applications with no host
processor resources required to copy virtual volumes. Either volume copy
can be used to satisfy a specific mount request. Functions allow the VTC
to maintain copy synchronization of the two VTSs and provide expedited
deletion of redundant logical volume copies from the tape volume cache.

Advanced Function/Advanced Policy Management
The Advanced Function feature (#4000) provides tape volume cache
management and export/import capability. The tape volume cache
management capability can be used with VTSs included in a VTS
Peer-to-Peer configuration. However, when feature #4000 is included in
configurations that include the Peer-to-Peer Copy Base feature (#4010),
the import/export function will be disabled. The Enterprise Tape Library
must have a Convenience I/O Station (either #5210 or #5230) if
import/export is enabled.
Advanced Policy Management
Volume Pooling, Selective Dual Copy, or Peer-to-Peer Copy Mode Control
require the Advanced Policy Management feature (#4001) and depending on
disk storage capacity, additional features may be required. The Tape
Volume Cache Management capability, Volume Pooling, Selective Dual Copy,
and Peer-to-Peer Copy Mode Control can also be used with VTSs included in
a PtP VTS. However, when feature #4000 or #4001 is included in
configurations that include the Peer-to-Peer Copy Base feature (#4010),
the import/export function will be disabled. The Advanced Policy
Management feature requires:
- Four or more 3590 tape drives associated with the VTS.
- The 10-Cartridge Convenience I/O Station (#5210), or the 30-Cartridge
Convenience I/O Station feature (#5230), must be installed on the IBM
TotalStorage Enterprise Tape Library Base Frame 3494 Model L10, L12, or
L14 if the Import/Export functions are to be used.
- At least 216 GB of cache storage when volume pools are defined.
- If installed on a 3494 Model B18, the Performance Accelerator (#5236)
is required.
Disk Capacity feature requirements with their associated Advanced
Policy Management features are:
Disk Capacity Disk Features Advanced Policy
(uncompressed) Qty. / Feature Number Management Features
-------------- ------------------------- -------------------
Up to 250 GB 1 / #3704 or 3 / #3702 #4001
Up to 500 GB 1 / #3705 or 4 / #3702 #4001 and #4002
The Advanced policy management feature may be installed on both VTSs
of a PtP VTS configuration. The Import/Export function is inoperable
when the Peer-to-Peer copy feature is installed. Use of volume pooling
or dual copy may result in a need to increase tape volume cache capacity
and the number of 3590 Tape Drives. Use of dual copy may reduce the
bandwidth available to host servers during peak periods of server
activity.
The device driver support for SCSI Host Attachment (#3422) does not
include the support for the Advanced policy management (#4001).
VTS 3592 Tape Drive support
The VTS Model B10 or B20 can now attach the 3592 Enterprise Tape Drive
Model J1A that is installed in an associated 3494 Expansion Frame Model
D22. The VTS Model B10 can attach either the 3592 Model J1A Tape Drives
or 3590 Tape Drives. Intermixing of tape drive types on a Model B10 is
not supported. The VTS Model B10 can attach 4 to 12 3592 Tape Drives.
The VTS Model B20 can have both 3590 and 3592 Tape Drives attached to the
same VTS. If only 3592 Tape Drives are attached to the VTS Model B20,
there can be 4 to 12 3592 Tape Drives contained in one 3494 Model D22
Frame (and all the 3592 Tape Drives must be in that same frame). If both
3590 and 3592 Tape Drives are attached to a Model B20, four to six 3590
Tape Drives are contained in one 3494 Model D12 Frame and 4 to 12 3592
Tape Drives are contained in one 3494 Model D22 Frame. Both standard
(300 GB) and economy (60 GB) 3592 cartridge media are supported, however
the VTS does not support WORM cartridge media or the scaling of standard
cartridge media to smaller capacities. Exported stacked volumes created
on 3592 Model J1A Tape Drives cannot be imported into a 3590 Tape Drive
VTS homogeneous configuration.
When adding a Model D22 Frame with 3592 Tape Drives to an installed
VTS subsystem, there must be enough cartridge slots available in the 3494
Tape Library to add the additional 3592 tape cartridges. If there are
not enough available slots, an additional storage frame may need to be
ordered, or the new reclamation policies can be used to consolidate 3590
cartridges to free up cartridge slots in the 3494 Tape Library.
To attach the 3592 Tape Drives to the VTS, the following features must
be installed:
- On the VTS Model B10 or B20:
- 5238 (3592 Drive Attached to VTS) - to provide the 3592 attachment
cards, and cables from the VTS to the 2Gb Fibre Channel Switches in the
3494 Model D22 Frame. This feature is available for plant installation
only on the VTS Model B10. The maximum distance between the VTS and a
3494 Model D22 Frame is 25 meters.
- 5245 (Dual Path Attachment) - to provide a second internal LAN
attachment.
- 4001 to 4004 (Advanced Policy Management) - required on the Model B20
if both 3590 and 3592 Tape Drives are attached.
- On the associated 3494 Model D22 Frame:
- 3060 (3592 Drive-to-Switch Cables) - one feature for each 3592 Tape
Drive should be ordered to provide the cables from the 3592 Tape Drives
to the 2Gb Fibre Channel Switch.
- 3486 (2Gb Fibre Drive Attachment) - provides mounting hardware to
install two 2Gb Fibre Channel Switches in the 3494 Model D22 Frame.
- 3487 (2Gb Fibre Channel Switch) - provides one 2Gb Fibre Channel
Switch for the 3494 Model D22 Frame. A quantity of two must be ordered.
- 9010 (Attached to a VTS) - to designate that this 3494 Model D22
Frame is associated with a VTS.
Note: The 3592 Model J1A is not supported for installation in the 3494
frame features (#5302, #5304, #5502, #5503, or #5504). A VTS microcode
update will be shipped with the addition of the 3592 Model J1A Tape
Drives in a 3494 Model D22 associated with a VTS. The VTS microcode
support of the 3592 Model J1A Tape Drives (VTS code level 2.31.730.xx, or
later) requires that the 3494 library manager (LM) be at LM code level
530.xx, or later. A new LM may be required to support the 3592 Model J1A
Tape Drive. Any 3494 Model L1x with feature number 9020, or one that has
a LM installed since May 15, 2000, should have a "compatible" LM that
will work with the 3592 Model J1A. Any prior LM is not "compatible" and
must be replaced. If the LM microcode level is at 527.xx, or later, then
the LM hardware prerequisites are already satisfied. The LM microcode
level can be checked by selecting "About" from the "Help" pull-down menu
on the LM Operator Menu. You may need the assistance of a customer
engineer to determine if the LAN PCI Library Manager feature (#5047) must
be ordered.
ESCON SFF to Duplex conversion cable
The Extended Performance ESCON Channels feature (#3412) now comes with
an MT-RJ connector. The ESCON cables shipped with feature #3412 have an
MT-RJ connector on one end, for connection to feature #3412, and a ESCON
Duplex connector on the other end. An 62.5-Micron MT-RJ to ESCON 2 meter
ESCON Jumper Cable feature (#9775) can be ordered to connect that cable
to host MT-RJ connectors. When pre-existing ESCON cables are planned to
be used instead of the ESCON cables normally shipped with feature #3412,
the jumper cable feature #9775 should be specified to connect those
pre-existing cables to the MT-RJ ESCON channel connector on the VTS. Up
to four of feature #9775 can be ordered for each feature #3412.
VTS Model B20 PtP support for four VTCs
The VTS Model B20 is supported in a PtP configuration with four VTCs,
with each VTC having 32 virtual devices for a total of 128 virtual
devices. To enable support of this configuration, the following feature
should be ordered instead of the 64 Additional Virtual Drives feature
(#5264):
- 5265 (Incremental Virtual Drives) - a quantity of two must be ordered
on the Model B20.
Feature #5264 is no longer available for a newly built Model B20. It
is only available as a field only MES when converting from a Model B18
that has the feature #5264 to a Model B20 that requires two #5264
features.
A configuration of eight VTCs, with each VTC having 32 virtual device
for a total of 256 virtual devices, can now be obtained when a quantity
of four of feature #5265 is on the Model B20.
The following PtP configurations are available:
Minimum # Total #
of Virtual Qty of Qty of of Virtual
VTS Drives #5264 #5265 Drives PtP Configuration
--- ---------- ------- ------- ---------- -----------------------
B10 64 - - 64 4 VTCs w/16 devices/VTC
B20 128 0 0 128 8 VTCs w/16 devices/VTC
B20 128 0 2 128 4 VTCs w/32 devices/VTC
B20 128 2(1) 0 256 8 VTCs w/32 devices/VTC
B20 128 0 4 256 8 VTCs w/32 devices/VTC
Note: (1) Feature #5264 should only be ordered when converting a Model
B18 with one #5264 (support for 128 devices) to a Model B20 with two of
#5264 (support of 256 devices total).
Dual Path Attachment on VTS
The Dual Path Attachment feature (#5245) is now required on any new
order of a VTS Model B10 or B20, or when adding the 3592 Drive Attached
to VTS feature (#5238) to an installed VTS Model B10 or B20. This will
require adding the Dual Concentrator feature (#5246) to the Model Lxx
Frame if it is not already installed. The Dual Path Attachment is
recommended on all VTS systems for improved availability.
Model B10 to B20 Conversion
When converting a Model B10 to a Model B20 VTS, the following features
may need to be ordered on the Model B20 concurrently with that upgrade:
- 3705 (Disk Storage) - convert Disk Storage feature #3704 and add
additional #3705 features to total two or four of #3705
- Add sufficient FICON or ESCON channel features of the following (or
convert feature 3418) to equal one of the valid Model B20 VTS attachment
configuration options:
- 3412 (Extended High Performance ESCON Channels)
- 3415 (Long Wavelength FICON Channel)
- 3416 (Short Wavelength FICON Channel)
- If the Model B10 is in a PtP configuration, add four additional VTCs,
and the associated Model CX0 or CX1 Frames
Note: Parts removed or replaced become the property of IBM and must be
returned.
Note: FICON Enablement is prerequisite for FICON attachments.
Model B16 Migration
To enable migration of an installed Model B16 VTS to a new Model B10
or B20 VTS, an installed Model B16 can be converted to a Tape Drive
Expansion Frame Model D12. The following features must be ordered on the
Model L10, L12, or L14 concurrently with that model conversion:
- 9003 (Drive Unit Attachment) must be added if feature number 9006
(Virtual Tape Server Attachment) is installed and that feature number
9006 must be removed
- 9005 (Drive Unit Attachment Greater Than 8 Frames) must be added if
feature number 9007 (Virtual Tape Server Attachment Greater Than 8
Frames) is installed and that feature number 9007 must be removed
Features for installing tape drives or any other Model D12 features
can be added to the converted Model D12. This conversion provides for
migrating the data off of a Model B16 on to a locally installed VTS
containing no data (uninitialized).
RS/6000 or pSeries Attachment
The VTS can attach to SCSI adapters on RS/6000 or pSeries systems with
the SCSI Host Attachment feature (#3422). Each #3422 feature provides
two SCSI bus host attachments and includes data compression compatible
with the ESCON High Performance Option. Each bus provides up to 16
virtual devices and emulates 3490E tape drives. This feature is
supported on selected RS/6000 systems with the appropriate software
support (refer to the Software Requirements section). The VTS
must have the following:
- An attached ESCON host system or "Call Home" capability enabled for
reporting maintenance information
- VTS Open Systems Device Drivers (#9201)
- RS/6000 Attachment (#9106)
One or two appropriate length SCSI cables should be specified per
feature (refer to the Cables section).
The SCSI Host Attachment (#3422) is supported for attachment to any of
the following RS/6000 adapters:
- Enhanced SCSI-2 Differential Fast/Wide Adapter/A (#2412)
- PCI Universal Ultra SCSI Adapter (#6204)
