Balancing the ContentServer 3000 Controllers
Any time one controller on a ContentServer goes down, which may be during an upgrade or
replacement, the active Slice Server processes on that controller, which manage ContentServers and
ContentStores, fail over to the remaining controller. Once both controllers are up and running,
Omneon recommends that you balance the Slice Server processes across controllers to improve
performance. This is done by using the Failback button on the ContentServer or ContentStore
Properties page.
Omneon recommends that you balance your ContentServer 3000 at these times:
• Following a ContentServer upgrade.
• Following a controller replacement.
• Following a controller failover.
• If the Managed ContentStores and ContentServers field on the ContentServer Properties
page shows all, or a large majority, of ContentStores and ContentServers being managed by one
controller (for example, five out of six).
If you fail to balance your ContentServer in the situations listed above, it may affect the performance
of the ContentServer.
NOTE: Omneon recommends that you schedule balancing during times when the system is not loaded. For
example, this may be late at night. System performance may be affected while balancing is occurring.
