HP Smart Array SAS Controllers

HP Smart Array P71 1m, P712m, and P721m controllers provide 6Gb SAS connections through
the BladeSystem c-Class enclosure high-speed mid-plane to the 6Gb SAS switch blade, allowing
external SAS storage enclosures to be connected to BladeSystem c-Class enclosures. Their 6Gb
SAS technology delivers data bandwidth up to 1200 MB/s per port (600 MB/s per SAS link),
and is fully compatible with 6G SAS, 3G SAS, 3G SATA, and 1.5 G SATA. Dual-port SAS and
single-port SATA disk drive interconnections are supported, offering deployment flexibility. In
addition, these models support HP Smart Array Server Software, including SmartStart, HP Systems
Insight Manager (SIM), Array Configuration Utility (ACU), and Smart Storage Administrator (SSA).
NOTE: The HP Smart Array P731m controller is supported only by SSA.
NOTE: The HP Smart Array P731m does not support the 3GB MDS600 or the 1.5 G HDD. For
