Figure 9 Configuration using SVP as virtual command device
NOTE:
If the SVP is used as the virtual command device, there is no need to set up a Virtual Command Device
server or command device. However, command processing using the SVP takes significantly longer,
so we recommend using a Virtual Command Device server for large-scale configurations.
The following figure shows a Virtual Command Device server configuration. The server connected to
the actual command device is set as the virtual command device on each pair management server
or application host. The Virtual Command Device server can be the same machine as the P9000 RAID
Manager server.
