iSCSI Storage
Consolidation
Figure 4-16
As shown in the figure, server consolidation is enabled by installing
an Eclipse 2640 SAN Router that provides iSCSI-to-native FCP
connectivity.
Stranded servers subject to consolidation do not require installation
at one physical location. Servers may be located in a data center or
remotely; however, consolidation provides logical connectivity and
access as though the servers were co-located. Servers can now access
robust, scalable, and easily managed SAN storage that provides
better data availability.
In general, the largest expense associated with an IT infrastructure
storage is the purchase of storage (disk and tape drives). However,
conventional architectures create multiple storage islands that make
efficient disk utilization nearly impossible. Many environments have
disk utilization rates below 50%.
Storage consolidation pools disk resources (no matter the location)
and provides disk management as a single entity shared between
servers. Consolidation addresses cost and utilization issues by
providing iSCSI-based storage connectivity to Fibre Channel servers.
