Support for the TS3400 library is provided on z/OS 1.6 or later, z/VM V5.2.0 or later, z/VSE V3.1.2 or later, and z/TPF V1.1 or later. The z/VM, z/VSE, and z/TPF operating systems support the TS3400 as an autoloader in Auto Mode. You might require later operating system versions to support tape encryption. Refer to Chapter 10, “Planning for software and
hardware to support tape drives” on page 191.
A wide variety of open systems platforms supports the IBM TS3400 Tape Library. For additional information, refer to the System Storage Interoperation Center (SSIC):

Encryption support
The IBM System Storage TS3400 Tape Library supports the IBM System Storage TS1120 or TS1130 tape drive built-in encryption capabilities. The TS3400 Tape Library supports Library-Managed Encryption (LME), System-Managed Encryption (SME), and Application-Managed Encryption (AME).
Three policy settings are available for Library-Managed Encryption on a TS3400:
Encrypt All
All cartridges in a non-partitioned TS3400 library will be encrypted. If you have partitioned a TS3400 library into two logical libraries, you can set the policy separately for each logical library.
Internal Label -Selective Encryption
The IBM TS1120 or TS1130 tape drive automatically derives the encryption policy and key information from the metadata that is written on the tape volume by the application.
NetBackup is currently the only backup software that supports Internal Label Encryption Policies.

NetBackup is currently the only backup software that supports Internal Label Encryption Policies.
In a System z environment, SME is the only option. You set the policies through the web interface.
4.6 IBM System Storage TS3500 Tape Library
The IBM TS3500 Tape Library (machine type 3584) is designed for medium to large
automated tape storage and backup solutions and is part of a whole family of tape libraries for small to large automated tape storage and backup solutions. The TS3500 offers a robust enterprise library solution available for midrange and high-end open systems. Since its introduction, the library has been enhanced to accommodate more drive types and operating platforms, including the attachment of System z (mainframe) hosts and tape controllers.
Combining reliable, automated tape handling and storage with reliable, high-performance IBM TS1130, TS1120, and TS1050 drives and LTO tape, the IBM TS3500 Tape Library offers outstanding retrieval performance with typical cartridge move times of less than three seconds.
The IBM TS3500 Tape Library can be partitioned into multiple logical libraries, making it an excellent choice for consolidating tape workloads from multiple heterogeneous open systems servers, and enables the support for System z attachment in the same library.
In addition, the IBM TS3500 Tape Library provides outstanding reliability and redundancy through the provision of redundant power supplies in each frame, an optional second cartridge accessor, control and data path failover, and dual grippers within each cartridge accessor. Now, you can upgrade both library and drive firmware nondisruptively, that is, without interrupting the normal operations of the library.
Figure 4-25 on page 121 shows the maximum configuration of 16 frames and the minimum configuration of one frame of an IBM TS3500 Tape Library, which can contain from one to 192 TS1130, TS1120, or LTO tape drives; and from 58 to 6,260 (frames for TS1120 only, or TS1130 only) or 6,887 (frames for LTO only) cartridge storage cells.

The IBM TS3500 Tape Library provides these functions:
Modular, scalable, automated tape library, combining IBM tape and automation for open systems and mainframe hosts, using a variety of IBM drive types
Attachment to IBM System z, System i, iSeries, AS/400, System p, pSeries, RS/6000, IBM System x, Netfinity, Sun, Hewlett-Packard, and other non-IBM servers
Connectivity using FICON, ESCON, Fibre Channel, Low Voltage Differential (LVD) SCSI, and High Voltage Differential (HVD) SCSI
IBM Multipath Architecture designed to support redundant control paths, mixed drive configurations, and library sharing between multiple applications
Tape data encryption
4.6.1 TS3500 frames
Seven frames are currently available to build an IBM IBM TotalStorage 3584 Tape Library.
Each frame is identified by a three character model number (L23, L53, D23, D53, S24, S54, or HA1) that describes the nature of the frame. Libraries are built of modules, as follows:
Each library requires a base frame (model Lxx) to which optional expansion frames (model Dxx or Sxx) can be added. Only one base frame is permitted in each library configuration.
Base and expansion Dxx frames support one of either drive:
– LTO drives (model x53)
– 3592 drives, 3592-J1A, TS1120, and TS1130 (model x23)
Storage frames (model Sxx) do not support drives, but they do support higher cartridge density.
Optional second accessor is made available through the addition of model HA1 frames.
You can intermix all currently available frame models with each other and with installed frame models with the provision that there is only one base frame in each library. Installed frame models include the L22, L32, L52, L53, D22, D32, D52, and D53.
A mix of 3592 and LTO drives within one library is supported, because frames for 3592 and LTO drives can be mixed. TS3500 frames are dedicated to either 3592 or to LTO. Therefore, you cannot mix these drive types in a single frame.
The following sections introduce the available frame models.
