Library Management Software
1-16 StorageTek SL8500 Library Guide
■ Optimized library performance through load balancing, automatic request recover
and retry, and multiple request processing in parallel.
■ Reduced downtime through dynamic configuration capabilities and queuing
commands during short-term library outages.
■ Enriched reporting and management capabilities for ease of use
Enterprise Library Software (ELS)
ELS incorporates multiple software products to monitor and manage tape libraries and
virtual solutions for a mainframe environment.
Host Software Component (HSC) and Storage Management Component (SMC)
HSC manages volume pools and communication with the SL8500 library. HSC resides
on the host, but is transparent to the operating system. A separate component, SMC,
provides the interface between z/OS operating systems and HSC. SMC resides on all
MVS hosts that perform tape processing with HSC.
HSC and SMC work together to influence allocations and determine policies, volume
locations, and drive ownership. HSC and SMC translate user requests into library
commands and provide message handling.
Virtual Tape Control System (VTCS)
VTCS is the host software that enables centralized management of StorageTek virtual
tape libraries, such as VSM and VLE. VTCS manages virtual tape volumes and drives,
which includes the migration and recall of virtual volumes and the use of real tape
cartridges and drives.
Concurrent Disaster Recovery Test (CDRT)
CDRT enables disaster recovery testing while the library or virtual storage is in use.
Independent Software Vendors (ISVs)
There are a variety of ISVs that support the SL8500 library. Some applications include:
■ ASG Time Navigator
■ CA ArcServe
■ Commvault Simpana
■ Dell NetVault
■ EMC DiskXtender
■ EMC NetWorker
■ FileTek StorHouse
■ HP Data Protector
■ IBM HPSS
■ IBM Tivoli TSM
■ MassTech MassStor
■ Oracle DIVArchive
■ Oracle HSM
