The IBM 3494 TotalStorage (TM) Enterprise Automated Tape Library is a
tape cartridge library designed to provide high availability of customer
data in both S/390 and Open Systems environments. Its affordable,
modular design helps allow the 3494 to grow as your business grows.
Flexible configuration choices start at a single frame with up to two
tape drives and up to 240 tape cartridges. Optional drive, storage, and
Virtual Tape Server units may be added as needed, to create an automated
tape library with up to 76 physical tape drives, 512 virtual tape drives,
or up to 6,240 tape cartridges. Choices in tape drives for the 3494 can
be the IBM TotalStorage Enterprise Tape Drive 3592, the IBM TotalStorage
Enterprise Tape Drive 3590, or the IBM 3490E. Different tape drives can
be installed in different frames in the same 3494 library. The 3494
supports a variety of IBM and Open Systems hosts including IBM eServer
zSeries, S/390*, IBM eServer pSeries, RS/6000*, IBM eServer iSeries,
AS/400*, Sun**, HP, and Intel-compatible servers running Microsoft
Windows** NT, 2000, and 2003. Also available are unique optional models
such as the IBM TotalStorage Enterprise High Availability Tape Frames
(HA1 Frames) and the IBM TotalStorage Virtual Tape Server (VTS). The HA1
Frames provide a second tape cartridge accessory and library manager for
high library availability and performance. The VTS is designed to
combine the speed of disk, the advantages of virtual tape drives, the
capacity and reliability of IBM 3590 tape technology, and the automation
of the 3494 to create a self-contained hierarchical storage management
subsystem. All this, in addition to remote console support, Simple
Network Management Protocol (SNMP) reporting capabilities, multi-host
attachment, and modular design, assist in making the 3494 flexible, easy
to use, and well-suited for automated tape library solutions.
Model Abstract 3494-B16
(For IBM US, No Longer Available as of December 31, 1998)
The IBM TotalStorage Virtual Tape Server (VTS) Model B16 for the
Enterprise Tape Library 3494, an integrated solution, provides a
hierarchical storage management system to attached ESCON* hosts by
integrating IBM Magstar 3590 Tape Drives, fault-tolerant RAID disk
storage, and a RISC-based controller. It appears to host systems as two
fully-configured 3490E tape subsystems. The Model B16 VTS contains 400
tape cartridge storage cells.
The Model B16 VTS must be integrated with an IBM TotalStorage
Enterprise Tape Drive Expansion Frame Model D12 and attached to an IBM
TotalStorage Enterprise Tape Library Base Frames Model L10, L12 or L14.
The Model B16 VTS is a single unit that contains fault tolerant RAID disk
storage and a RISC based controller. It must have a Model D12, with 3,
4, 5, or 6 Magstar 3590 tape drives, attached adjacent to it in the
Enterprise Tape library. The Model B16 VTS contains storage cells for
400 tape cartridges.
Modular, expandable, automated tape libraries with a low entry price
providing an automated tape solution to a variety of system environments
and capacities
Provides a solution for automating tape operations such as
save/restore, migration of data between direct access storage devices
(DASD) and tape, and other mass data applications.
Model Highlights 3494-B16
Provides a hierarchical storage management system for attached ESCON
systems that can:
Lower tape operating costs
Reduce the number of tape cartridges supporting tape operations
Reduce the number of tape drives required
Reduce the tape robotics required for automation
Reduce the floor space required to store tape volumes
The Model B16 VTS, an integrated solution, integrates IBM technologies
to provide an ESCON attached hierarchical storage management system for
ES/3090, ES/9000, and S/390 systems. It uses IBM Magstar 3590 Tape
Drives, IBM fault-tolerant RAID disk storage, a RISC-based controller,
and IBM's award winning Enterprise Tape Library. The Model B16 VTS
provides a cost/performance solution to:
Exploit tape capacity
Exploit tape resources
Reduce tape storage and operating costs
Exploit Tape Capacity
The Model B16 VTS integrates advanced tape, robotics, and disk
technologies to exploit the 10GB (30GB with 3:1 compaction) capacity of
the High Performance 3590 Cartridge Tape and the 9 MBps data rate of the
Magstar 3590 Tape Drive. The Model B16 VTS, which presents an image of
two fully configured 3490E tape subsystems (32 drives total) to attached
hosts, will initially store tape volumes (called virtual volumes) on the
integrated attached disk storage. Then, after the tape is unloaded, it
writes the virtual volume to a High Performance 3590 Cartridge Tape
(owned by the VTS) with other previously written virtual volumes to form
a stacked volume and fill a cartridge with data. Previously written tape
volumes, called logical volumes, that are stored on a tape cartridge,
will be moved back to integrated disk storage when referenced by an
attached host processor. Demounted logical volumes residing on the
integrated disk storage can be remounted for immediate access without
actually mounting the tape cartridge containing the logical volume. A
virtual volume can store up to 800MB of data. Virtual and logical
volumes that contain less than 800MB only consume the actual number of
data bytes in the disk storage and 3590 cartridge. Large datasets can
span multiple virtual volumes. A copy of the virtual volume is kept in
the integrated disk storage until is again accessed by an attached host
processor or deleted from the disk storage to make room for other virtual
volumes.
Based on a sample of customer data, the Model B16 VTS can reduce the
number of tape cartridges required by as much as a factor of 59 through
exploitation of the 10GB capacity of the High Performance 3590 Cartridge
Tapes using hierarchical storage management. The effect in any
particular customer environment will be dependent on the characteristics
of their data, such as dataset size, and cartridge capacity.
Exploit Tape Resources
The Model B16 VTS will move entire tape volumes between the Tape
Volume Cache and the Magstar 3590 tape drives at one time. The Model B16
VTS provides bandwidth management to service multiple open tape volumes
and exploit the 9 MBps transfer rate of the Magstar 3590. The result is
a reduction in the number of required tape drives.
Reduced Tape Storage and Operating Costs
By placing multiple logical 3490E tape volumes onto a single 3590 tape
volume, the number of required tape cartridges and tape drives, and
automated storage capacity is greatly reduced. The floor space occupied
by those cartridges, tape drives, and automation systems is
correspondingly reduced. The reduction in cartridges, tape drives, and
automation also brings a reduction in operations handling to process the
workload. This reduction can help lower the total tape operating costs
by lowering the purchase price and maintenance of hardware and reducing
overall operating costs.
Integrated Storage Hierarchy
The Model B16 VTS integrates advanced tape drive, robotic, and
fault-tolerant, RAID disk storage technologies using robust software to
form an integrated storage hierarchy to exploit the 10GB (30GB with 3:1
compaction) capacity of the High Performance 3590 Cartridge Tape and the
9 MBps data rate of the Magstar 3590 Tape Drive. The Model B16 VTS
provides space for up to 144GB of disk storage, a RISC-based tape
controller for data transfer and advanced storage management, and 400
cartridges of storage. Because the VTS stacks multiple logical volumes
onto a single High Performance 3590 Cartridge Tape, the 3494 can now be
configured based on storage capacity rather than cartridge storage slots.
A 3494 with a Model B16 VTS must have an associated Model D12 for the
Magstar 3590 B1A tape drives used by the Model B16 VTS. The integrated
fault-tolerant RAID disk has a capacity of up to 144GB. A quantity of
two or four of feature number 3701 should be specified to order the size
of the integrated disk storage. The cache storage holds tape data before
it is written to 3590 cartridges. The RISC controller, integrated in the
Model B16 VTS, provides a single data path with two ESCON adapters
capable of simultaneously transferring data. The controller:
Transfers data between attached hosts and tape volume cache storage
and between tape volume cache storage and attached 3590 B1As
Manages cache storage contents and tape volume contents
Maintains a database of volumes
Contains two ESCON channel attachments, each supporting 64 logical
paths
The database is stored in fault-tolerant RAID disk storage and
database recovery is facilitated by transaction journals in the event the
database must be recovered. Model B16 VTS configurations can consist of
3, 4, 5, or 6 Magstar 3590 Tape Drives in an associated Model D12 and
either 72GB or 144GB of integrated fault-tolerant disk storage.
Expanded 3494 Capabilities
A 3494 with a VTS can be configured with any other model of 3494. A
combination of 3490E and 3590 technologies is also supported. Previously
installed 3494 configurations can be upgraded to contain a Model B16 VTS.
A 3494 configuration can include a single Model B16 VTS along with its
required Model D12.
New Concepts
The Model B16 VTS introduces the new concepts of:
Virtual devices, a representation of 32 3490E devices that are
emulated on disk storage
Virtual volumes, the representation of emulated Cartridge System Tape
cartridges or Enhanced Capacity Cartridge System Tape cartridges stored
on disk storage
Logical volumes, the representation of emulated Cartridge System Tape
cartridges or Enhanced Capacity Cartridge System Tape cartridges stored
on High Performance 3590 Cartridge Tapes
3490E Emulation
The Model B16 VTS presents an image of a two fully configured 3490E
tape subsystems to attached hosts and supports the entire 3490E command
set. It will store new tape data on volumes (called virtual volumes) on
the integrated attached disk storage, then after the tape is unloaded,
write the virtual volume to a High Performance 3590 Cartridge Tape Volume
(owned by the VTS) with other previously written virtual volumes to form
a stacked volume and fill the volume with data. Previously written tape
volumes, called logical volumes when stored on a tape cartridge, will be
moved back to integrated disk storage when referenced by an attached host
processor, if they no longer reside on the integrated disk storage.
Neither logical volumes nor the High Performance 3590 Cartridge Tapes on
which they are stored can be removed from the 3494. The logical volumes
must be copied to removable media such as a 3490E volume or native 3590
volumes to remove the data from the Model B16 VTS.

Model B16 to Model D12
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 Model D12 Tape
Drive Expansion Frame. 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 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).
The Model B16 VTS contains one or two banks of fault tolerant RAID
disk storage, and a RISC based controller for attachment to ESCON
channels of host systems. It must have a Model D12, with 3, 4, 5, or 6
Magstar 3590 tape drives, attached adjacent to it in the 3494. The Model
B16 VTS contains storage cells for 400 tape cartridges.
Only one Model B16 VTS can be attached to an Enterprise Tape Library
Base Frame Model L10, L12, or L14. A Model D12 with 3, 4, 5, or 6
Magstar 3590 tape drives must be attached adjacent to the Model B16. A
quantity of two or four of feature code 3701 must be ordered. Cartridges
in the 3494 created by the Model B16 VTS that contain stacked volumes of
active data should not be removed from the 3494.
The Model B16 VTS attaches to ESCON channels on ES/3090, ES/9000, and
S/390 systems. Using ESCON Directors, the Model B16 VTS can be up to 43
kilometers from the host system. A Tape Drive Expansion Frame Model D12
must be associated with the Model B16 VTS by specifying feature number
9010 on the Model D12 and it is installed adjacent to the Model B16.
Model B16 VTS configurations can consist of 3, 4, 5, or 6 Magstar 3590
Tape Drives in an associated Model D12 and either 72GB or 144GB of
integrated fault-tolerant disk storage.
No SCSI cables need to be specified on the 3590 Tape Drives in the
associated Model D12 as they are provided automatically (when feature
9010 is specified on that Model D12).
Feature #9006 must be applied to the Tape Library Base Frame Model
L10, L12, or L14 when the Model B16 VTS is attached in the first eight
frames. One feature #9007 must be applied to the Model L10, L12, or L14
and to the Model B16 VTS that is attached in 3494 beyond the first eight
frames. This is required to assure that proper cables are shipped and
configuration records are correct. Feature #5214 (Second Disk Drive),
one feature #5228 (Tape Control Unit Expansion), and feature #5229
(Expansion Attachment Card) are also required on the Model L10, L12, or
L14 when a Model B16 VTS is attached.
The standard 3494 allows four RS232 host connections and four tape
control unit connections. The Expansion Attachment Card feature #5229
provides an additional four RS232 host connections and four tape control
unit connections. The Tape Control Unit Expansion feature #5228 can
convert the four host connections to four tape control unit connections
on either the standard 3494 or the Expansion Attachment Card. A Model
B16 VTS requires one host connection and two control unit connections,
plus from three to six additional control unit connections for the drives
in the associated Model D12. Thus a 3494 that contains a Model B16 VTS
can have up to ten other tape control units installed, depending on the
number of associated 3590 drives and the quantity of feature #5228
installed, with the actual maximum number as shown below:
MAXIMUM NUMBER OF TAPE CONTROL UNITS (WHEN B16 INSTALLED)
3494-B16 CONFIGURATION (1)#5228 (2)#5228
----------------------------------------- -------- --------
Three 3590 drives in associated Model D12 7 10
Four 3590 drives in associated Model D12 6 9
Five 3590 drives in associated Model D12 5 8
Six 3590 drives in associated Model D12 4 7
(Note: Feature #5228 is not required if a Model HA1 Frame is attached
to the Model L10, L12, or L14. A Tape Control Unit is one 3490-C1A/C2A,
SCSI attached 3490-F1A, 3590-A50 or A00, or a SCSI attached 3590-B1A in
any combination.)
If the configuration of frames in an installed 3494 needs to be
changed, for example if frames must be moved to install an Model B16 VTS,
or if frames must be moved from one 3494 library to another, then an RPQ
request must be processed before the library can be reconfigured. An RPQ
is required for moving feature numbers 5300, 5302, 5304, and 5400, or
Models B16, D10, Model D12, D14, and S10 which will ensure that the
proper cables are available.
The Model B16 VTS appears to attached host processors as two fully
configured 3490E tape subsystems. The software support is thus the same
as for 3490E on ES/3090, ES/9000, and S/390 software in the following
offerings:
ES/3090, ES/9000, S/390
MVS DFSMS 3490E support:
MVS/ESA SP Version 4.3, 5.1, or 5.2 (For JES3: JES3 Version 4.2.1,
5.1.1, or 5.1.2 is required).
