The Model B18 VTS, a second generation integrated Seascape solution, snaps-in IBM advanced technologies to provide an ESCON attached hierarchical storage management system for S/390, ES/3090, ES/9000, RS/6000, Sun, HP, and Intel-compatible servers running Microsoft Windows NT or Windows 2000. It integrates IBM 3590 Tape Drives, a RISC-based controller, RAID disk storage, and IBM's TotalStorage Enterprise Tape Library 3494. The Model B18 VTS provides the tape control unit function for the virtual tape drives and the hierarchical storage management function for management of the tape volume cache and the 3590 stacked volumes. It contains a RS/6000 symmetric multiprocessor, attachment of three to twelve 3590 Tape Drives, and IBM fault-tolerant RAID disk storage. The base Model B18 VTS includes two standard ESCON channels, support of 32 virtual device addressing, and up to 288 GB of disk storage capacity. The Model B18 VTS is externally attached to the 3494 tape library. Features are available which allow 128 virtual tape drive addressing, and data compression for improved performance and effective cache capacities of over 5 TB (assuming 3:1 compression). Up to eight Extended Performance ESCON host channel attachments or up to four SCSI bus attachments can be specified. The Model B18 VTS provides a cost/performance solution to:

• Exploit tape capacity
• Exploit tape resources
• Reduce tape storage and operating costs
• Automate dual copy

Exploiting Tape Capacity

The Model B18 VTS integrates advanced tape drives, robotics, and disk technologies to utilize the up to 120 GB capacity of the 3590 Cartridge Tape and the high performance data rate of the 3590 Tape Drive. The VTS, which presents an image of 3490E tape subsystems (up to 128 drives) to attached hosts, will initially store tape volumes (called virtual volumes) on the integrated attached disk storage in compressed form if the ESCON High Performance Option or Extended High Performance Option features is installed. Then, after the tape volume is demounted, it writes the virtual volume to a 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 2.4 GB (compressed) of data. Virtual and logical volumes only consume the actual number of data bytes in the disk storage and on the 3590 cartridge. Large datasets can span multiple virtual volumes. A copy of the virtual volume is kept in the integrated disk storage until the disk storage is needed to make room for other virtual volumes.

Exploiting Tape Resources

The Model B18 VTS can move entire tape volumes between the tape volume cache and the 3590 Tape Drives at one time. The VTS provides bandwidth management to service multiple open tape volumes and can exploit the 14 MBps transfer rate of the 3590. The result is a reduction in the number of required tape drives.

Reducing 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 the need for automated storage capacity is significantly 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 helps bring 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 VTS integrates advanced tape drives, robotics, and fault-tolerant RAID disk storage technologies using robust software to form an integrated storage hierarchy to help exploit the up to 120 GB capacity of the 3590 Extended High Performance Cartridge Tape and the 14 MBps data rate of the 3590 Tape Drive. Because the VTS stacks multiple virtual volumes onto a single 3590 cartridge Tape, the 3494 can now be configured based on storage capacity rather than cartridge storage slots. The enhanced VTS configurations consist of a Model B18 VTS and associated Tape Drive Expansion Frame Model D12s with three to twelve 3590 Model H1A, E1A, or B1A Tape Drives.

The Model B18 VTS contains an advanced function RS/6000 symmetric multiprocessor for data transfer, with integrated fault-tolerant disk storage, and advanced storage management. Various sizes of integrated disk storage can be specified. The cache storage holds tape data before it is written to 3590 cartridges. The RISC controller, integrated in the Model B18 VTS, provides the host data paths with SCSI or ESCON host channel attachments capable of simultaneously transferring data. The Model B18 VTS:

• Transfers data between attached hosts and tape volume cache storage and between tape volume cache storage and attached 3590 Tape Drives

• Manages cache storage contents and tape volume contents

• Maintains a database of volumes

• Contains up to eight Extended Performance ESCON host channel attachments or up to four SCSI bus attachments

• Emulates two to eight 3490E Magnetic Tape Subsystems

• Contains tape volume cache

Virtual Tape Concepts

The VTS provides:

• Virtual drives, a representation of up to 128 3490E drives 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 3590 Cartridge Tapes

3490E Emulation

The Model B18 VTS presents an image of two to eight 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 in compressed form if the ESCON High Performance Option or Extended High Performance Option features are installed. After the tape volume is demounted, it will write the virtual volume to a 3590 Cartridge Tape Volume (owned by the VTS) with other previously written virtual volumes to form a stacked volume and fill the physical 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. Logical volumes can be removed from the 3494 through the use of the Advanced Function Export function.

Expanded 3494 Capabilities

Expanded capabilities now available in an Enterprise Tape Library 3494 with a Model B18 VTS include:

• Up to 250,000 logical volumes per VTS
• Up to 256 virtual drives with two Model B18s
• Up to two VTSs per 3494 library
• Improved configurability

Advanced Function Feature

The Model B18 Advanced Function Feature (#4000) will provide host controlled functions to further exploit the use of tape and disk subsystems in the virtual tape server. The first of these functions are Tape Volume Cache Management and Import/Export. The ESCON High Performance Option (#3200), or the Extended High Performance Option (#3400) and the Extended Performance ESCON Channel (#3412), is a prerequisite for this feature (#4000).

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 cache management capability of the Advanced Function feature can be used with VTSs included in a Peer-to-Peer VTS (PtP VTS).

Import/Export

The Model B18 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 PtP VTS configuration.

• Export

  The Export function allows you to identify a set of logical volumes as a group and have those volumes placed on a set of physical volumes that can then be removed from a VTS. The host initiated export operation will copy logical volumes from a physical stacked volume to the target physical exported stacked volume and delete the logical volumes from the VTS. The export operation allows multiple destinations to be specified and will create one or more exported stacked volumes for each destination. An exported logical volume will only be included on one exported stacked volume.

• Import

  The Import function allows you to identify a set of logical volumes that reside on physical volumes exported from one VTS to be added to another VTS. The host initiated import operation provides a number of options:

  • Import an entire exported stacked volume
  • Import selected logical volumes from an exported stacked volume
  • Import logical volumes as scratch volumes
  • Import logical volumes as newly initialized volumes

  An empty exported stacked volume can be reused by a VTS or a native 3590 application.

VTS Import/Export will support customer activities such as:

• Disaster Backup

  You have a need to protect your enterprise's data assets. In many industries, data is the corporate product. Without these assets you may be unable to run your business or compete effectively in their industry. Most customers protect their data assets by periodically making a copy of critical data and placing it in a remote site for recovery in the event there is a disaster at the local site. The data can either be physically moved after copying or the copy operation can transfer the data over a communication facility to a remote site to eliminate physical movement and reduce the exposure to loss of backup data. Currently, the preferred method is physical offsite movement of tape volumes.

  The disaster backup data will be restored to:

  • Test disaster recovery procedures,
  • recover from a disaster at the local site, and
  • recover from a data loss at the local site.

• Work Load Move

  Occasionally, you have a need to move selected data from one location to another using a portable media that uses devices common to the sending and receiving sites. In most cases, but not all, the source data will be moved (as opposed to sending a copy) to the receiving site. With a VTS, it is also possible as your workload grows, the data in a single VTS will need to be split between two VTSs.

• Archive

  Your VTS configuration may not have the physical capacity to contain all the data you decide to store in the VTS. Thus, you need to have a capability to move data out of the VTS but still have it available for ready access should it be required at some future time. Archive data is data that has a low frequency of usage and can be moved out of a VTS with minimal impact on your operations.

• Interchange

  Customers have a continuing need to exchange data with other sites within their enterprise, or with vendors, customers, or governments. Interchange occurs on mutually agreed upon media that can be processed at sites within the sending and receiving organizations. Including interchange data within the VTS reduces the number of external devices required and extends the VTS benefits to more data.

Tape Specialists

The IBM TotalStorage Enterprise Tape Library Specialist and the IBM TotalStorage Peer-to-Peer VTS Specialist provide comprehensive status, capacity, and performance information to monitor storage resources from any location within an enterprise. Two Specialists are available on the 3494 that enable you to monitor and manage specific devices:

• The Tape Library Specialist is a system-independent, web-based user interface to the 3494 library manager, which enables you to monitor the library manager and attached Virtual Tape Servers from a remote location.

• The Peer-to-Peer VTS Specialist is the web user interface used to view the current status and configuration of the PtP VTS.

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.

PtP VTS

A PtP VTS uses robust distributed servers (VTCs) to interconnect two VTSs (Model B10, B18, or B20) using ESCON or FICON attachments. The VTC can be a Model AX0 housed in a Virtual Tape Frame 3494 Model CX0 or a feature on the Virtual Tape Frame 3494 Model CX1. The Peer-to-Peer Copy VTS features provide automatic copy of virtual volumes into both Model B18 VTSs in a PtP VTS. When a volume is requested the PtP VTS automatically retrieves one of the copies from either VTS. For even greater data protection, the VTSs in a PtP VTS can be in different locations to help protect against disasters. The PtP VTS automatically provides a copy of all newly created or updated virtual volumes in both interconnected VTSs using either of two modes of operation:

• Immediate Copy - which creates a copy in the companion connected VTS upon receipt of a Rewind Unload command and provides the highest level of protection of your data available in the VTS

• Deferred Copy - which schedules creation of a copy in the companion connected VTS after receipt of a Rewind Unload command as activity permits

A pair of interconnected Model B18 VTSs in a PtP VTS will appear to attached host processors as a single automated tape library with:

• Four or eight fully configured independent "3490E" tape subsystems with 16 tape drives each (64 or 128 virtual tape drives total)

• Eight or sixteen ESCON channels

• Up to 10.4 TB (with 3:1 compression) of disk storage

• A maximum capacity of 250,000 logical volumes

Each PtP VTS will consist of four or eight VTCs and two VTSs with each having 432 GB to 5.2 TB (with 3:1 compression) of disk storage and four or more 3590 Model H1A, E1A, or B1A Tape Drives. A total of 864 GB to 10.4 GB (with 3:1 compression) of disk storage will be available for tape volume cache and up to twelve 3590 Tape Drives will be available for copy and recall activity.

A copy of all virtual volumes will be maintained in both VTSs. The VTCs will automatically create the second copy and maintain the copy synchronization of the two VTSs. The accessibility of the copy will depend on the mode of operation selected, either "Immediate Copy" or "Deferred Copy". The mode of operation will determine the peak performance of the PtP VTS.

Performance

The performance of the PtP VTS will depend on customer data characteristics and the mode of copy operation selected. In the Deferred Copy mode, the scheduling of a volume copy will be determined by the VTC and its execution will have a lower priority than host I/O operations and allow a higher peak period bandwidth. If Immediate Copy mode is selected, then the copy operation is performed prior to the completion of the unload processing of the volume.

PtP VTS Components

The interconnected components of a PtP VTS are:

• Model B18 VTS - VTS with the Peer-to-Peer Copy feature

• Model AX0s - provide host ESCON attachment and interconnection of two Model B18 VTSs

• Model CX0 - holds up to four Model AX0s

• Model CX1 - holds two or four VTCs (two or four VTC features on the Model CX1, or two Model AX0s and two Model CX1 VTC features)

Model B18 VTS With Peer-to-Peer Copy

A Model B18 VTS with the Peer-to-Peer Copy features is an independently operating distributed server node in a PtP VTS. A Model B18 VTS with the Peer-to-Peer Copy features incorporates all the functional capability of the Model B18 VTS except for SCSI host attachment and the Import/Export capability of the Advanced Function feature. The Model B18 VTS incorporates new channel commands to support large block transfers of compressed logical volumes to and from the VTCs. Added 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.

It is highly recommended that both Model B18 VTSs be configured with the same disk storage capacity. Each of the Model B18 VTSs in a PtP VTS continues to operate during scheduled or unscheduled service of the other Model B18 VTS.

Remote Operation

A 3494 VTS or the components of a PtP VTS can be connected over extended distances for remote operation. The IBM 2029 Fiber Saver can be used to provide connectivity over longer distances between a host system and a Model B18 VTS. The maximum end-to-end distance of the host system to Model B18 ESCON interface, including the Fiber Saver pair length, is 75 km.

The components of the PtP VTS can be separated by ESCON distances up to 26 km to provide the copy of virtual volumes in a remotely located 3494 VTS. One of the Model B18 VTSs and two or four VTCs in the PtP VTS can be attached to Enterprise Tape Library 3494 that is located up to 26 km from the second Model B18 VTS and the two or four other VTCs in the PtP VTS that are attached to another 3494. The IBM 2029 Fiber Saver can be used to provide connectivity between a host system and a VTC, and between a VTC and a Model B18 VTS. The maximum end-to-end distance of the host system to VTC ESCON interface, including the Fiber Saver pair length, is 75 km. The maximum end-to-end distance of the VTC to Model B18 ESCON interface, including the Fiber Saver pair length, is 50 km. Host system processors can be attached locally to two or four VTCs and remotely to another two or four VTCs; in other words, processors in both locations can be attached to the PtP VTS and process virtual volumes in VTSs in both locations.

"Call Home" Service Support

The "Call Home" function, when activated, automatically opens a service alert when a problem occurs with the Model B18, VTC, or a 3590 Model A60 or A50 Controller in a 3494 tape library. 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.

Open Systems SCSI Host Attachment

The SCSI Host Attachment feature permits open systems host attachment through industry-standard SCSI busses. Each SCSI Host Attachment (#3422) 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 3490E tape drives. Each feature supports a maximum of 16 virtual devices. The feature supports attachment to the SCSI-2 standard interface on selected RS/6000, Sun, HP, or Windows servers. One or two SCSI attachment features may be installed in the Model B18 VTS and requires the VTS Open Systems Device Drivers (#9201) as a prerequisite. Either an ESCON host system must be attached, or the VTS must have the Extended High Performance Option feature (#3400) and "Call Home" capability must be enabled.

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 open system.

Product Positioning

The IBM TotalStorage Virtual Tape Server (VTS) are premier tape solutions 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 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. The VTS provides 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 features and functions available in the VTS 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 Peer-to-Peer VTS (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 3590 Tape Drives to help reduce the total cost of ownership of tape solutions for z/OS, OS/390, MVS, TPF, z/VM, VM/ESA, VSE/ESA, AIX, Windows, and UNIX environments.

Model Conversions B16 to B18 Model Conversion An existing Model B16 VTS can be converted to a Model B18 VTS having the EHPO feature. This model conversion includes the removal of the RISC controller and disk storage capacity features in the Model B16, which are returned to IBM, and the addition of a stand-alone Model B18 frame with appropriate features (refer to the Hardware Requirements section). The Model B16 frame is converted to either a storage or drive unit frame which remains a part of the 3494 library. The Additional Tape Storage Frame will be feature number 5500 on the Tape Library Base Frame Model L10, L12, or L14. The drive frame can be either feature number 5502 (an associated drive frame for another Model B18), feature number 5503 (a drive frame with SCSI attached tape drives), or feature number 5504 (a drive frame with ESCON attached tape drives). Parts removed as a result of this model change become the property of IBM. B18 to B20 Model Conversion An installed Model B18 VTS can be converted to a Model B20 VTS. The Model B18 VTS frame is replaced with a Model B20 frame that includes a new RISC controller. Refer to the Model B20 sales manual for features that need to be added or removed with this conversion. Parts removed as a result of this model change become the property of IBM. Back to top   Technical Description Physical Specifications Operating Environment Limitations Hardware Requirements Software Requirements The Model B18 VTS integrates IBM 3590 Tape Drives, a RISC-based controller, RAID disk storage, and the Enterprise Tape Library 3494 to provide an ESCON and SCSI attached hierarchical storage management system for multiple servers. The Model B18 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. It contains a RS/6000 symmetric multiprocessing processor, server attachments, attachment of 3 to 12 3590 Tape Drives, and IBM fault-tolerant RAID disk storage. The base Model B18 includes two standard ESCON channels, support of 32 virtual tape drive addressing, and up to 288 GB of disk storage capacity. The Model B18 VTS is externally attached to the 3494 tape library with SCSI cables to 3590 Tape Drives in an associated Tape Drive Expansion Frame Model D12 (or feature #5502). The Model B18 VTS is also attached via a LAN connection to the library manager in the Tape Library Base Frame Model L10, L12 or L14. Features are available which allow 128 virtual device addressing, and data compression for improved performance and effective cache capacities of over 5 TB (assuming 3:1 compression). Up to eight Extended Performance ESCON host channel attachments or up to four SCSI bus attachments can be specified. PtP VTS The PtP VTS will interconnect two Model B18 VTSs with Virtual Tape Controllers (VTCs) to provide both remote and local peer-to-peer copy capability between two VTSs using ESCON connections. 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. The interconnected Model B18 VTSs and VTCs can be in separate locations to allow remote copy for remote vaulting applications. A PtP VTS having a local VTS and a remote VTS can enhance the disaster backup and recovery process and improve data availability and recovery. Each component in a PtP VTS is replicated one or more times to maximize access to data and eliminate single points of failure. Access to volumes will be maintained after single and some multiple component failures. Service on one component of the PtP VTS can occur concurrently with the operation of the rest of the PtP VTS. Automatic copy of volumes between two local VTSs will improve data availability, data recovery, and balance workload between the VTSs. The interconnected components of a PtP VTS are: Model AX0s - provide host ESCON attachment and interconnection of two Model B18 VTSs Model B18 VTS - Model B18 VTS with the Peer-to-Peer Copy feature Model CX0 - holds two or four Model AX0s Model CX1 - 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 VTSs in a PtP VTS will appear to host processors as a single image VTSs which will have: Four or eight fully configured independent "3490E" tape subsystems with 16 tape drives each (128 virtual tape drives maximum) Up to 16 ESCON channels Up to 10.4 TB (with 3:1 compression) of disk storage A maximum capacity of 250,000 logical volumes A Model B18 VTS with the Peer-to-Peer Copy features is an independently operating distributed server node in a PtP VTS.

The Model B18 VTS incorporates channel commands to support large block transfers of compressed logical volumes to and from the VTCs. New 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. Both interconnected Model B18 VTSs in a PtP VTS attach to four or eight VTCs at a maximum distance of 26 km using ESCON directors, or up to 50 km using an IBM 2029 Fiber Saver. It is highly recommended that both Model B18 VTSs be configured with the same disk storage capacity. Each of the 3494 Model B18 VTSs in a PtP VTS continues to operate during scheduled or unscheduled service of the other Model B18 VTS.

Associated Model D12s must be physically next to each other if more than six 3590 Tape Drives are included in the Model B18 VTS configuration. Cartridges in the 3494 created by the VTS that contain stacked volumes of active data should not be removed from the 3494. Emulation of four 3490E subsystems that have 64 virtual addresses requires the EHPO feature #3200, or feature #3400 and #3412, and at least 144 GB of cache (i.e., two or more of feature #3702, one feature #3704, or one or more of feature #3705). Emulation of up to eight 3490E subsystems that have up to 128 virtual addresses requires the EHPO feature #3200, or feature #3400 and #3412, and at least 288 GB of cache (i.e., four of feature #3702, or one or more of feature #3705). The 128 virtual addresses also require the Performance Accelerator feature #5236 and the 64 Additional Virtual Drives feature #5264. The device driver support for SCSI Host Attachment (#3422) does not include the support for the import or export of logical volumes capability included in the Advanced Function (#4000).

Using ESCON Directors, the Model B18 VTS can be up to 43 kilometers from the host system. The Model B18 VTS is externally attached to the 3494 Tape Library Base Frame Model L10, L12, or L14. Two Model B18 VTSs having the Peer-to-Peer Copy features can be interconnected with four or eight VTCs in a PtP VTS configuration to provide both remote and local peer-to-peer copy capability between two VTSs using ESCON connections. The base Model B18 VTS includes two standard ESCON host channel attachments. To have two enhanced ESCON host channel attachments with data compression for greater performance, the following feature must be specified: 3200 (ESCON High Performance Option) To have Extended Performance ESCON Channels (#3412) with data compression for greater performance, one of the following features must be specified: 3200 (ESCON High Performance Option) 3400 (Extended High Performance Option) A maximum of two #3412 features, for a total of four Extended Performance ESCON Channels, can be installed. The Activate Additional ESCON Channels feature (#3418) will enable use of a second pair of ESCON channels included with the Extended Performance ESCON Channels feature (#3412). This feature requires the Performance Accelerator feature (#5236). One feature #3418 is required for each feature #3412 or #3200 installed. Two of feature #3418 activates eight Extended Performance ESCON channels. Feature #3412 and #3418 can be combined with feature #3422 to provide four Extended Performance channels and four SCSI buses. The Activate Additional ESCON Channels feature #3418 is not used on a Model B18 VTS in a PtP VTS configuration without the 64 Additional Virtual Drives feature #5264, and will be disabled when the Peer-to-Peer copy feature #4010 is installed. When feature #5264 is installed on the Model B18 VTS in a PtP VTS, two of feature #3418 must be installed. If feature #3200 or #3400 is specified, the Advanced Function feature and additional host attachments may be specified with the following features: 4000 (Advanced Function) 3302 (Additional Enhanced ESCON Channel Attachments) 3412 (Extended Performance ESCON Channels) 3422 (SCSI Host Attachment) Two 30.5 meter (100 foot) ESCON cables are included with each feature #3412 or #3418 to attach to host system ESCON channels. If different ESCON cable lengths are needed, they must be ordered separately.

Two Specialists are available on the 3494: The IBM TotalStorage Enterprise Tape Library Specialist is a system-independent, web-based user interface to the 3494 library manager, which enables you to monitor the library manager and attached Virtual Tape Servers from a remote location. Connection to customer LANs will be through the Token-Ring Adapter (#5219) or the Ethernet Adapter (#5220) features on the Model L10, L12, or L14 Tape Library Base Frame. The IBM TotalStorage Peer-to-Peer Virtual Tape Specialist is the web user interface used to view the current status and configuration of the PtP VTS configuration. This Specialist requires a customer supplied Ethernet network which is connected to the VTCs. Software Requirements The Model B18 VTS appears to host systems as two, four, or eight fully configured "3490E" tape subsystems. Emulation of four 3490E subsystems with 64 virtual addresses requires the EHPO feature #3200, or feature #3400 and #3412, and at least 144 GB of cache (i.e., two or more of feature #3702, one feature #3704, or one or more of feature #3705). Emulation of up to eight 3490E subsystems with 128 virtual addresses requires the EHPO feature #3200, or feature #3400 and #3412, and at least 288 GB of cache (i.e., four of feature #3702, or one or more of feature #3705). The 128 virtual addresses also require the Performance Accelerator feature #5236 and the 64 Additional Virtual Drives feature #5264. The software support is thus the same as the support for 3490E. The minimum levels of currently supported software support for 3490E are as follows. Note: Earlier levels of software that are no longer in service may operate with the hardware but are not tested or recommended. ES/3090, ES/9000, S/390, or zSeries MVS 3490E support: OS/390 Version 2 Release 6, or later, or z/OS Version 1 Release 1, or later, and their associated levels of DFSMS Basic Tape Library Support (BTLS) Version 1.4.0, or later EREP Version 3.5 plus Program Temporary Fixes (PTFs) MVS Advanced Function Support Functional exploitation of the VTS Advanced Function feature is provided in DFSMS. There are no associated changes required for MVS/SP, OS/390, or z/OS. Toleration PTFs are provided to allow import/export enhanced hosts to share an Import/Export capable VTS with other MVS, OS/390, or z/OS host systems that do not have Import/Export capability. DFSMS/MVS support for VTS Import/Export includes programming and interactive interfaces that improve overall host management of virtual tape resources, as well as enabling control of import and export operations for virtual volumes. Enhancements include: Additional and Expanded Programming Interfaces An assembler macro provides two new tape processing functions, IMPORT and EXPORT. These functions enable import and export operations to be initiated under program control. Enhanced Entry Processing The cartridge entry installation exit is enhanced to support import processing of logical volumes on stacked volumes. Enhanced Eject Processing The cartridge eject installation exit is enhanced to support export processing of logical volumes on stacked volumes. Expanded Operator Command Support LIBRARY IMPORT and LIBRARY EXPORT commands are provided to enable interactive initiation of import and export processing. In addition, DISPLAY SMS commands for VOLUME, LIBRARY, and OAM are enhanced to provide specific details associated with status and attributes of VTS library resources. Pre-ACS Exit For Tape Management Systems Storage Management Subsystem (SMS) supports a new user exit routine invoked before calling automatic construct selection (ACS) routines to allow the tape management system to influence construct selection. Expanded Console Message Support New messages are added and existing messages are enhanced to provide status information on VTS import and export processes and to enable problem determination/resolution. z/VM 3490E support: z/VM Version 3 Release 1, or later for guest operating system support DFSMS/VM Function Level 221 required for native VM support EREP Version 3.5 plus PTFs VM/ESA 3490E support: VM/ESA Version 2.3, or later for guest operating system support DFSMS/VM Function Level 221 required for native VM support EREP Version 3.5 plus PTFs VSE/ESA (as a VM/ESA guest) 3490E support: VSE: VSE/ESA Version 2.3 plus PTFs, or later VM: VM/ESA Version 2.3, or later VM: DFSMS/VM Function Level 221 plus PTFs EREP Version 3.5 plus PTFs TPF 3490E support: TPF Version 4.1 plus PTFs DITTO/ESA for MVS Support DITTO/ESA for MVS Version 1 Release 3 will provide a VTS Exported Volume Read Utility to: Extract a logical volume from an Exported Stacked Volume and create a physical volume containing only the single logical volume Provide a list of logical volumes contained on an Exported Stacked Volume This support is available through APAR PQ26582. PtP VTS Support The PtP VTS appears to attached host system software as four or eight fully configured independent "3490E" tape subsystems with 16 tape drives each (up to 128 virtual drives) in a single composite library with associated Cartridge System Tape or Enhanced Capacity Cartridge System Tape cartridges. This allows applications that use IBM's current 3490E tape drives and automation systems to easily use the PtP VTS. Software support for the PtP VTS is provided in OS/390 and z/OS. Enhancements to DFSMS/MVS allow the host to recognize that a library is a PtP VTS. The host is aware of the distributed, or peer, VTSs as well as the composite PtP VTS library image that contains virtual drives and logical volumes. The operations staff can request the status of distributed VTS libraries and the composite PtP VTS library image. With the enhanced software, the host can identify the originating distributed library related to events and status changes so that the operations staff sees useful messages when intervention is required. In addition, the host logs hourly statistical records from distributed libraries as well as from the composite PtP VTS library image. The OS/390 software support is provided as an SPE for DFSMS/MVS 1.4 and 1.5. For later releases, support is packaged in OS/390 or z/OS. Toleration PTFs are provided for systems that will not be running at the full support level. At least one host attached to the PtP VTS must be at the full support level with PTFs installed so that the PtP VTS library reliability and serviceability features in the software can be enabled. All other OS/390 hosts attached to a PtP VTS must have at least the toleration PTFs installed. Native VM/ESA hosts and VSE/ESA guest hosts of VM/ESA attached to a PtP VTS are supported in an environment in which an OS/390 host with full support of PtP VTS is also attached to the library. The OS/390 host provides essential visibility to the status of distributed PtP VTS components, while a VM/ESA host has awareness only of the composite library image. Software requirements for VM/ESA and VSE/ESA for PtP VTS are the same as those for other 3494 and VTS libraries. Tape Management Systems Support Using DFSMSrmm (or independent software vendor tape management systems), you can initiate the movement of logical volumes to stacked volumes or the copy of logical volumes from stacked volumes into a virtual tape server. Independent software vendors for tape management systems should be contacted regarding their plans for support of the import/export capability.
