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) shows the connection of I/O path between servers and disk array systems
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.
