Configuration Rules for the Controller
The following list defines maximum configuration rules for the controller:
■ 128 visible LUNs/200 assignable unit numbers
— In SCSI-2 mode, if the CCL is enabled, the result is 127 visible LUNs and
one CCL.
— In SCSI-3 mode, if the CCL is enabled, the result is 126 visible LUNs and
two CCLs.
Note: In SCSI-2 mode, if the Command Console LUN (CCL) is enabled, and in SCSI-3
mode where the CCL is always enabled, the result is 127 visible LUNs and one CCL.
■ 1.024 TB storageset size
■ 96 host connections
■ 72 physical devices for BA370-based packaging; 84 physical devices for all
others
■ 20 RAID 3/5 storagesets
■ 30 RAID 3/5 and RAID 1 storagesets (see note)
■ 45 RAID 3/5, RAID 1, and RAID 0 storagesets (see note)

limited to no more than 20 RAID 3/5 storagesets in the individual combination.
■ 8 partitions of a storageset or individual disk
■ 6 physical devices per RAID 1 storageset (mirrorset)
