• P9000 RAID Manager response time and virtual command devices, page 246
About virtual command devices
Command devices are used to send P9000 RAID Manager commands between the pair management
server and a storage system. Command devices use the FC link (known as an in-band connection).
Virtual command devices allow you to perform the same operations using the LAN (known as an
out-of-band connection). This configuration uses either the Service Processor (SVP) of the storage
system, or a dedicated P9000 RAID Manager server (known as a Virtual Command Device server).
The following figure shows an example of a configuration in which SVPs are used as virtual command
devices. Because this configuration eliminates the need for connecting a command device to the pair
management server, you can install Device Manager Agent and P9000 RAID Manager on the
management server, allowing it to double as a pair management server.
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.
