Library Management Software
Note – The same Sun StorageTek library management software currently used by the customer today can be upgraded to support the SL8500 library.
Nearline Control Solutions
Some of the Sun suite of Nearline Control Solutions (NCS) software products are described in the sections below.
Client System Component
MVS/CSC provides client functions and communications between an MVS host and the Library Control System (LCS) or server on a

Storage Management Component
Storage Management Component (SMC) is the interface between IBM’s OS/390 and z/OS operating systems and a Sun library. SMC performs the allocation processing, message handling, and SMS processing for the NCS solution. SMC resides on the MVS host system with HSC and/or MVS/CSC, or on a remote system using the Sun StorageTek HTTP server to communicate with the HSC. SMC communicates with HSC or MVS/CSC to determine policies, volume locations, and drive ownership.
Note – SMC is a required NCS component.
Sun StorageTek HTTP Server
Sun StorageTek’s HTTP Server for OS/390 and z/OS optionally provides the middleware to allow communication between the SMC (client) and a remote HSC subsystem (server). The HTTP server executes as a separate subsystem on the MVS host where the remote HSC subsystem resides.
