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)
Note: For the previous two storageset configurations, this is a combined maximum,
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)
■ 14 physical devices per RAID 3/5 storageset (RAIDset)
■ 24 physical devices per RAID 0 storageset (stripeset)
■ 48 physical devices per RAID 0+1 storageset (striped mirrorset)
■ 146 GB disks (for universal drives only) are the largest supported for the
HSG60 and HSG80 storage array.
