Configuration Rules

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.
