● Maximum dedicated spares per linear disk group = 4
● Maximum global spares per system = 64
● Maximum ADAPT groups per controller module = 4
● Maximum ADAPT single disk size = 64 TiB
● ADAPT stripe width = 8+2
Minimum and maximum disks per virtual disk group:
● NRAID (non-RAID):1/1 (read cache only)
● RAID 0: 2/2 (read cache only)
● RAID 1: 2/2
● RAID 3 Not supported
● RAID 5: 3/16
● RAID 6: 4/16

Minimum and maximum disks per linear disk group:
● NRAID (non-RAID):1/1
● RAID 0: 2/16
● RAID 1: 2/2
● RAID 3: 3/16
● RAID 5: 3/16
● RAID 6: 4/16
● RAID 10: 4/16
● RAID 50: 6/32
● ADAPT: 12/128
Volumes, Initiators, hosts, and mapping:
● Maximum virtual volumes per system = 1024
● Maximum linear volumes per system = 512 (recommended)
● Maximum volume size – 128 TiB (approximately 140 TB)
● Maximum mappable volumes (LUNs) per disk group = 128
● Maximum mappable virtual volumes (LUNs) per pool = 512
● Maximum mappable linear volumes (LUNs) per pool = 128
● Maximum mappable volumes (LUNs) per controller module = 512
● Maximum virtual volumes per pool = 1024 (512 base volumes and 512 snapshots)
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.
● Maximum linear volumes per pool = 1024
● Maximum virtual volumes per volume group = 1024
● Maximum volume groups per controller module = 256
● Maximum volumes per host port = 1024 (Microsoft Windows limits access to 256)
● Maximum initiators per host port = 1024
● 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
