HP Direct-Connect External SAS Storage for HP BladeSystem Solutions Depoyment Guide

• Ability to grow as storage demands increase. The MSA2000sa controller enclosure can
support up to three cascaded drive enclosures. For detailed information about
maximum-capacity configurations, see the MSA2000sa QuickSpecs.
• Choice of high performance enterprise class dual-port SAS drives or low cost, high capacity
archival class single-port SATA drives.
Configuration, management, and monitoring tasks are performed using the Storage Management
Utility (SMU) or Command Line Interface (CLI), both of which are embedded in MSA2000 family
array controller firmware. For more information about these software utilities, see “Software
information” (page 38). Functionality of the two user interfaces is similar, but presented in different
screen formats. HP recommends becoming familiar with and primarily using one of the two
interfaces.

Important tips
• Be sure to upgrade the MSA2000sa controllers to the latest firmware version before connecting
to the switch.
• For high availability, two controllers must be installed in each MSA2000sa controller enclosure,
and two I/O modules must be installed in each MSA2000 drive enclosure.
• When cabling the MSA2000sa controller enclosure, MSA2000 drive enclosures, and HP
3Gb SAS BL Switches, be sure to follow HP recommended best practices. For more information
about cabling the devices, see the user documents for the devices. Suggested references
include the HP 2000sa Modular Smart Array supported cable configurations, HP 2012sa
