Important tips
•
If needed, upgrade the P2000 G3 SAS MSA controllers to the latest firmware version
before
connecting to the switch.
•
For dual-domain configurations, two controllers must be installed in each P2000 G3 SAS MSA
controller enclosure, and two I/O modules must be installed in each drive enclosure.
•
When cabling the P2000 G3 SAS MSA controller enclosure, P2000 drive enclosures, and
HP 6Gb SAS BL Switches, be sure to follow HP recommended best practices to provide a
highly available solution. For more information about cabling the devices, see the user
documents for the devices. Suggested references include the
HP P2000 G3 MSA System
Cable Configuration Guide

HP P2000 G3 MSA System SAS User Guide
, and

To connect P2000 drive enclosures to the P2000 G3 SAS MSA controller enclosure, a Mini-SAS
to SAS cable must be purchased. For more information, see the MSA2000 QuickSpecs or
