For example, assume that you have 100 important clients, 500 regular clients,
and four media servers. You can use two media servers to back up your most
important clients and two media servers to back up your regular clients.
The following example describes how to configure a favorable client-to-server
ratio:
■ Configure the media servers for OpenStorage and configure the storage.
■ Configure a disk pool.
■ Configure a storage unit for your most important clients (such as STU-GOLD).
Select the disk pool. Select Only use the following media servers. Select two
media servers to use for your important backups.
■ Configure a backup policy for the 100 important clients and select the
STU-GOLD storage unit. The media servers that are specified in the storage
unit move the client data to the storage server.
■ Configure another storage unit (such as STU-SILVER). Select the same disk
pool. Select Only use the following media servers. Select the other two media
servers.
■ Configure a backup policy for the 500 regular clients and select the STU-SILVER
storage unit. The media servers that are specified in the storage unit move the
client data to the storage server.
Backup traffic is routed to the wanted data movers by the storage unit settings.
Note: NetBackup uses storage units for media server selection for write activity
(backups and duplications) only. For restores, NetBackup chooses among all media
servers that have logon credentials to the storage server.
About separating OpenStorage SAN client traffic
If you use the NetBackup Fibre Transport option, you can use one disk pool and
multiple storage units to manage backup traffic. You can separate the NetBackup
SAN client traffic from the regular NetBackup client traffic. Because all storage
units use the same disk pool, you do not have to partition the storage.
The following example describes how to separate SAN client traffic:
■ Configure the FT media servers and the regular media servers for OpenStorage
and configure the storage.
■ Configure a disk pool.
