The control cabinet contains: · · · · · AMU PMAC Power supply Drives Drive Controller (optional for some drives) Figure 2-5 Drive/Control Cabinet 10 Oct 1996 Hardware Components 2-9 Insert/Eject Unit Media are inserted into and ejected from the AML/J through the I/EF. The media are loaded by an operator into bins. With the base AML/J Insert/Eject Unit, the media is entered or retrieved through the door. With the IE/F-D, the door must be opened to insert or retrieve media. The capacity and number of bins are determined by the type of IE/F and media. The I/EF incorporates a media depository that stores unidentified volumes, defective media, and used cleaning devices.

The Expansion Unit was designed to increase the capacity of the AML/J. Additional Insert/Eject units and additional media are available through the Expansion Unit. See Figure 2-8. Figure 2-8 Expansion Unit Drive Unit Note For each additional Drive Expansion Unit, a corresponding media Expansion Unit is required. The Drive Expansion Unit was designed to increase the number of available tape drives in the AML/J. 2-12 System Description 600338-B Software Components EMASS software organizes and manages the AML/J. This software makes automated data manipulation possible without interfering with the performance of host system. EMASS software automatically receives messages, coordinates tasks, manages and updates the library database, and provides recovery from media errors. EMASS software can be tailored for many different library configurations. In addition, it can be reconfigured to accommodate an expanding library. MVS Support Unlimited MVS system images support is provided by Host Control Component (HCC-MVS) software. This software integrates transparently with MVS S/370, S/390, and Sysplex environments. Host Control Component (HCC) software Media functions are routed from the host computer to the AMU AMS software. Media functions supported by HCC software include the following: · · · · · · Mount/Keep operations Volume insertion/ejection Administration of media transport cleaning Media label initialization and verification Automatic reply to outstanding Write to Operator with Reply (WTOR) Scratch media management Communications functions between the host and AMU AMS software are provided by the following means: · · · Local or remote VTAM LU2 (standard 3270 support) EXCP standard console communication (local NON-SNA 3x74 control unit) LU6. 2 (APPC via Token-Ring or Ethernet adapter) 10 Oct 1996 Software Components 2-13 Minimum software requirements to support EMASS software in the MVS environment include the following: · · · · · MVS-SP1. 3. 6 for JES2 MVS-SP2. 2 for JES3 SMP/E Assembler H Standard MVS utilities UNIX Support Software solutions to accessing a media libraries are implemented through the UNIX virtual file system layer. AMASS software AMASS software presents the AML/J library as on-line direct access mass storage. The AMASS software provides the following features: · · · · · The AML/J library appears a single device The AML/J library utilizes a single mount point The data on the media appears as a standard UNIX directory with files Write or read to media utilizes the same approach as magnetic disk Raw cache partitioning provide high performance Files are accessible across the network through standard communication protocol. The protocols include: · · · · · · NFS TCP/IP RFS FTP Telnet HYPERchannel Requirements to support AMASS software are platform dependent. Additional detailed information is provided in the part number 600307 AMASS Documentation Set manuals. DataMgr software DataMgr is an integrated, layered, file migration application that requires and operates with AMASS software. DataMgr provides the following features: 2-14 System Description 600338-B · · · · · · · Fully distributed architecture File migration from expensive magnetic disk space to inexpensive storage media Transparent access to the migrated files Convenient access to migrated data during reloads Flexible migration policies determine the criteria for file relocation File replication across distributed servers Multi-tier migration Additional detailed information is provided in the part number 600336 DataMgr Documentation Set manuals. FileServ software FileServ software balances on-line media with stored library media fro quick access to data. The FileServ software provides the following features: · · · · · · The data on the media is accessed via standard UNIX operations using filesystem(s) as tracking points Tracks multiple users of the same file to prevent multiple mount actions File migration from expensive magnetic disk space to inexpensive storage media Transparent access to the migrated files Flexible migration policies determine the criteria for file relocation Media error are retained as a means to identify suspect defective media Files are accessible across the centralized or distributed environments through: · · · · Ethernet FDDI HYPERchannel UltraNet® Requirements to support FileServ software are platform dependent. Additional detailed information is provided in the part number 600309 FileServ Documentation Set (for SGI) manuals and the part number 600255-01 FileServ Documentation Set (for Convex) manuals. 10 Oct 1996 Software Components 2-15 VolServ software VolServ software handles volume manipulation by class of data and media migration. The Volserv software provides the following features: · · · · · · · · Provides a robotic independent interface to a variety of robotic systems Determines on-line or stored media volume location Issues manual or robotic commands to retrieve and mount media Allows multiple clients to share a single media library User defined classes of media share a media library Supports multiple media types Pools drives to allow drives to be shared among clients User defined migration policy allows media to be migrated between on-line and off-line storage Once a media volume is mounted, the files are accessible across the centralized or distributed environments through: · · · · Ethernet FDDI HYPERchannel UltraNet® Requirements to support VolServ software are platform dependent.
