● Maximum initiators per controller module = 4096
● Maximum initiators per host = 128
● Maximum hosts per host group = 256
● Maximum host groups per system = 32
● Maximum commands per LUN (preferred path = 4096
● Maximum queue depth per host port = 1024
Supported FC/iSCSI module host-port configurations per controller module:
● 4 ports FC
● 4 ports iSCSI
● 2 ports FC and 2 port iSCSI

Virtual volume snapshots:
● Maximum snapshots per pool = 512
● Maximum base volumes per system = 1024
● Maximum base snapshots per snappable volume
○ 254 in the volume snapshot tree with a license and the large pools feature
disabled in the CLI
○ 8 in the volume snapshot tree with the large pools feature enabled in the CLI
● Maximum mappable snapshots per system = 1024
NOTE: Active snapshots and replications use a substantial amount of the reserved
space and undesired effects might occur if the reserved space is completely
consumed. Use the CLI command show snapshot-space to monitor space
usage.
Virtual volume replication:
● Maximum number of peer connections per system = 4
● Maximum number of replicated volumes per system = 32
● Maximum number of replicated sets for a volume = 1
● Maximum number of volumes for a replicated volume group = 16, if no other
volumes belong to a replication set
● Minimum replication frequency that can be scheduled = 1
N/A
Maximum SCSI reservations
● Per controller module = 1024
● Per LUN = 1
Maximum SCSI registrations for virtual storage
● Per system: 32768
● Per LUN: 4096
Maximum SCSI registrations for linear storage
● Per system: 32768
● Per FC LUN: 128
● Per iSCSI LUN: 85-128 depending on IQN length
● Per SAS LUN: 128
● Presenting the same volume (LUN) through FC AND iSCSI to one or more hosts or
host groups is not supported.
