3.4 Host Ports
The HSG80 controller has two host ports. You can specify a maximum of 64
units per port, for a total of 128 LUNs total (127 if CCL is enabled). The
StorageWorks solution software only enables 16 LUNs per port, however. If you
need support for more than 32 LUNs, refer to Section 7.8 of these notes.
4.0 CONFIGURATION RULES
The following list outlines the configuration rules for the controller:
• Maximum 128 visible LUNs/200 assignable unit numbers
• Maximum 512 GB LUN capacity
• Maximum 72 physical devices
• Maximum 20 RAID-5 storagesets
• Maximum 30 RAID-5 and RAID-1 storagesets
• Maximum 45 RAID-5, RAID-1, and RAID-0 storagesets
• Maximum 8 partitions of a storageset or individual disk
• Maximum 6 members per mirrorset
• Maximum 14 members per RAID-5 storageset
• Maximum 24 members per Stripeset
• Maximum 48 physical devices per striped mirrorset
5.0 OPERATING CONSTRAINTS
This section describes the operating constraints for ACS Software Version 8.5.
An operating constraint is a limitation placed on the operation of the controller.
Other constraints on host adapters or other system components may also apply
(these are described in Section 7.0, host operating system notes). Keep these
constraints in mind to avoid problems and to help achieve the maximum
performance from your RAID system.
