View the refurbished HP Smart Array P431/2GB FBWC 12Gb 2-ports Ext SAS Controller 698531-B21 729636-001 Quickspecs here
The HP Smart Array P431 Controller is a low profile, PCIe3 x8, 12 Gb/s capable Serial Attached SCSI (SAS) RAID controller that provides enterprise class storage performance, increased external scalability, and data protection for select HP ProLiant Gen8 rack and tower servers. It features eight external physical links and delivers increased server uptime by providing advanced storage functionality, including online RAID level migration (between any RAID levels) with flash back write cache (FBWC), global online spare, and pre-failure warning. Data compatibility between HP Smart Array Controllers means customers can easily upgrade to future Smart Array Controllers.
The SA-P431 Controller supports up to 200 physical drives
The SA-P431 Controller supports the HP D3600, D3700, D2600, and HP D2700 Disk Enclosures (up to 8 daisy chained). Seamless upgrades to current or next generation HP high performance and high capacity Serial Attached SCSI Smart Array controllers.
12 Gb/s SAS performance when used on a DL580 Gen8 with MSA 2040 Storage or D3000 Disk Enclosures
6 Gb/s SAS technology delivers high performance and data bandwidth and contains full compatibility with 6 Gb/s SATA technology
PCI Express Gen3 x8 link width delivers high performance and data bandwidth up to 8GT/s theoretical maximum bandwidth
2 GiBytes Flash Backed Write Cache (FBWC) or 4GiBytes Flash Backed Write Cache kit with Battery (FBWC) provides read ahead caching and write back caching with indefinite write cache data retention in the case of unexpected power outage
Capable of supporting both legacy and UEFI boot operation on a DL580 Gen8 server
Standard on the P431 are RAID 6, RAID 60, RAID 1 ADM, Capacity Expansion, mirror split, recombine, and rollback in Online Mode, Drive Erase, Performance Optimization-Degraded Reads and Read Coalescing, Move/Delete any individual LUNS
The HP SSD Smart Path feature included in the Smart Array software stack improves SSD reads for all RAID levels and RAID 0 write operations by optimizing the path to each SSD attached to the controller
The HP SmartCache feature (HP Smart Cache license is required on P431) is a controller-based read caching solution in a DAS environment that caches the most frequently accessed data ("hot" data) onto lower latency SSDs to dynamically accelerate application workloads
HP Secure Encryption is a Smart Array controller-based data encryption solution for ProLiant Gen 8 servers that protects sensitive, mission critical data.
Mix-and-match SAS and SATA hard drives lets you deploy drive technology as needed to fit your computing environment
Support for SAS tape products
Software consistency on most current shipping Smart Array products: HP Smart Storage Administrator, HP Systems Insight Manager, and HP Intelligent Provisioning. The HP Smart Storage Administrator configures and manages a host of Smart Array controllers and other storage devices using a single interface. It replaces the HP Array Configuration Utility (ACU) with an updated design and configuration enhancements.
