Solution 1967594.1 : Solaris Cluster 4.x and Oracle FS1-2 Flash Storage System; Basic SCSI-3 reservation limits and implementation information.

Applies to:

Oracle FS1-2 Flash Storage System - Version All Versions to All Versions [Release All Releases]
Solaris Cluster - Version OSC 3.3 3/13 to OSC 4.2 [Release 3.3 to 4.2]
Information in this document applies to any platform.

Goal

To inform the reader about scsi3 reservations on the FS1-2 Flash Storage System.

Solution

Oracle Solaris Cluster 4.x software supports from one to 16 cluster nodes in a cluster. Different hardware configurations impose additional limits on the maximum number of nodes. For example FS1-2 Flash Storage System allows only 4 cluster node connections because of the number of host connections to any lun on the array is 4. SCSI-3 reservations are implemented per lun (not per port) on the FS1-2 storage array.

The (actual) limit of keys per lun is 64.
