Storage Management Component (SMC) is the interface between Fujitsu's MSP/EX operating system and Oracle's StorageTek automated library control systems, HSC.
SMC resides on every MSP host that accesses StorageTek real and virtual tape hardware. It operates on JES systems and is a required ELS component.
SMC primary functions include:
Influencing tape allocation according to hardware requirements and customer policies to ensure that appropriate tape drives are selected
Intercepting tape management and operating system mount, dismount, and swap messages and translating them in order to request the required tape hardware functions from the appropriate ELS automated library control system
Coordinating requests among multiple StorageTek TapePlexes
A TapePlex is a single StorageTek hardware configuration, normally represented by a single HSC Control Data Set (CDS). A TapePlex may contain multiple Automated Cartridge Systems (ACSs) and Virtual Tape Storage Subsystems (VTSSs).
SMC may communicate with any number of TapePlexes, using cross address space facilities to communicate with HSC running on the same host, and TCP/IP to communicate with HSC systems executing on other hosts.
Note:
For the purposes of this publication, HSC refers to the MSP implementation of HSC. The VM implementation of HSC is not supported by SMC.
