The refurbished HP Smart Array P712m mezzanine card is the preferred high value solution for 6Gb/s Shared SAS Storage for the HP ProLiant BladeSystem servers. It is one of the highest performing controllers in the SAS portfolio and provides new levels of reliability for the HP BladeSystem through its support of the latest SCSI technology and advanced RAID capabilities. Supports up to 4 P2000 Smart Arrays.

• Storage interface (SAS/SATA), 6 Gb/s SAS technology delivers up to 600 MB/s per physical link. 3 Gb/s SATA technology delivers up to 300 MB/s for directly attached SATA drives. Mix-and-match SAS and SATA drives. Deploy drive technology as needed to fit the computing environment. Support for SAS tape drives, SAS tape autoloaders and SAS tape libraries. RAID controller features, 256 MB cache, RAID 0, 1, RAID 0, 1, 3, 5, 6, 10, 50 on P2000 G3 SA (for shared storage)

• Recovery ROM protects against ROM corruption, Smart Array PCIe mezzanine card that connects to a HP 6Gb/s SAS BL Switch through the c-Class enclosure high-speed mid-plane supporting shared SAS storage.
  Four (4) 6Gb/s SAS physical links distributed across 2 external 2x ports to supports up to 2 6Gb/s SAS Switches, Two (2) 6Gb/s SAS physical links distributed across 2 internal 1x ports to support up to 2 6Gb/s SAS HDDs
  Software consistency among all Smart Array family products: Array Configuration Utility, Systems Insight Manager, Array Diagnostic Utility (ADU) and SmartStart. 

• Online array expansion (with cache), Online logical drive extension (with cache), Online RAID level migration (with cache), Online strip size migration (with cache), User selectable rebuild priority, User selectable RAID level and stripe size. 

• HP Storage Management Utility (SMU). Management access, out-of-band: WEB GUI, CLI. Interface Types: USB, 10/100 Ethernet. Protocols Supported: SNMP, SMI-S, SSL, SSH, SMTP, FTP, HTTP, Telnet 

• In addition to the usual RAID levels, the P2000 G3 features several important additional levels. RAID 6 is the highest level of RAID protection. It allocates two sets of parity data across drives and allows simultaneous write operations. It can withstand two simultaneous drive failures without downtime or data loss. RAID 10 is mirroring and striping without parity. It is the most popular of the multiple RAID levels, allowing large arrays with high performance in most cases and superior fault tolerance. RAID 50 combines the block striping and parity of RAID 5 with the straight block striping of RAID 0, yielding higher performance than RAID 5 through the addition of RAID 0, particularly during writes.

• The following features offer detection of possible failures before they occur, allowing preventive action to be taken:

  S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at HP detects possible hard disk failure before it occurs, allowing replacement of the component before failure occurs.
  Drive Parameter Tracking monitors drive operational parameters, predicting failure and notifying the administrator.
  Dynamic Sector Repairing continually performs background surface scans on the hard disk drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
  Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure preventative maintenance.

• Supported Servers: HP ProLiant BL280c G6, HP ProLiant BL460c G7, HP ProLiant BL465c G7, HP ProLiant BL490c G7, HP ProLiant BL495c G5, HP ProLiant BL495c G6, HP ProLiant BL620c G7, HP ProLiant BL680c G7, HP ProLiant BL685c G7
