Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution
Software Version 8.7A for Novell NetWare

Configuration Rules
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.
• 1.024 TB storageset size
• 96 host connections
• 84 physical devices
• 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.
• 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)
• 45 physical devices per RAID 0+1 storageset (striped mirrorset)
SCSI-2 to SCSI-3 Migration
In order to extend interoperability within the heterogeneous SAN, StorageWorks
highly recommends that customers begin migrating from SCSI-2 to SCSI-3 protocols.
Moving to SCSI-3 allows greater diversity in the operating systems and storage
products (including EVA) that comprise a SAN.
All migrations from SCSI-2 to SCSI-3 should be planned during scheduled downtime.
SCSI migrations require a controller restart and most likely a server restart. Data
contained on CCL units needs to be moved to new units once SCSI migration is
complete.
