2 Environmental Prerequisites
System configuration
The system configuration requirements for VSS Provider are shown below.
The HPE VSS Hardware provider must be installed on both the backup and recovery
application server (such as the media server in a Symantec NetBackup environment) and
the application server (such as a Microsoft Exchange server) from which a backup will be
taken.
Table 1 (page 12)
and the connection that VSS Provider gives an operation direction to the disk array systems
for FC environment support.
In the case of XP P9500/XP7, the command device must be mapped on an application
server and a backup server.
IPv6 is not supported.
Fiber channel switches are not always required. Use them according to your environment
as needed.
Multiple disk array systems can be connected to both an application server and a backup
server.
For the application server, a cluster configuration using MSCS (MSFC) is also possible. (For
the backup server, this configuration is impossible.)
The necessity of using the same operating system on both the backup server and the
application server depends on the backup software.
