You can create state database replicas on either a dedicated slice, or on a slice that will be used as part of a simple metadevice, mirror, RAID5 metadevice, or trans metadevice. Refer to Solstice DiskSuite 4.2.1 Reference Guide for guidelines on planning the location of state database replicas.
You can add additional state database replicas to the system at any time. The additional state database replicas can help ensure DiskSuite availability.
Adding additional state database replicas before creating a mirror can increase the mirror's performance. As a general rule, add one additional replica for each mirror you add to the system.
The maximum number of state database replicas is 50. This also applies to replicas that are part of a diskset.
