For SAN Volume Controller version 4.2.1 and earlier, the master console provides a single point from which to manage the SAN Volume Controller nodes. The master console could be purchased as a hardware product option (which includes the master console preinstalled software) or as a software-only option. Although it can no longer be purchased, the master console can be upgraded to support clusters running the latest SAN Volume Controller software.
Beginning with SAN Volume Controller version 4.3.0, the IBM® System Storage® Productivity Center (SSPC) is an integrated hardware and software solution that provides a single point of entry for managing SAN Volume Controller clusters, IBM System Storage DS8000® systems, and other components of your data storage infrastructure. For more information on SSPC, see the IBM System Storage Productivity Center Introduction and Planning Guide.
The master console can support up to two SAN Volume Controller clusters. Although multiple master console servers can access a single cluster, you cannot concurrently perform configuration and service tasks if multiple servers are accessing one cluster.
