22 SAN Volume Controller: Best Practices and Performance Guidelines 2.1 Advantages of virtualization The IBM System Storage SAN Volume Controller ( SVC), which is shown in Figure 2- 1, enables a single point of control for disparate, heterogeneous storage resources. The SVC enables you to put capacity from various heterogeneous storage subsystem arrays into one pool of capacity for better utilization and more flexible access. This design helps the administrator to control and manage this capacity from a single common interface instead of managing several independent disk systems and interfaces. Furthermore, the SVC can improve the performance of your storage subsystem array by introducing 8 GB of ...
