Administrator Guide

Since server clusters defined on a Storage Center must have the same operating system, all servers in the
Fluid Cache cluster must also have the same operating system. If a Storage Center server with matching HBAs
was previously created on the Storage Center prior to the assignment and it was defined with a different
operating system on the Storage Center, than the Fluid Cache cluster will not be able to assign the Storage
Center to the Fluid Cache cluster.
When a Fluid Cache cluster has servers that are part of a Storage Center server cluster, the Storage Center
server cluster becomes a sub-cluster under the Fluid Cache cluster when the Storage Center gets assigned to
the Fluid Cache cluster. To maintain cluster rules, if a server in the Fluid Cache cluster is part of a Storage
Center server cluster, than all Fluid Cache servers from the Storage Center server cluster must be in the Fluid
Cache cluster.
