HP Smart Array P822 Controller
The HP Smart Array P822 is HP's 24 port Serial Attached SCSI (SAS) RAID controller with PCI-e 3.0. This high performance SAS RAID controller provides high levels of reliability for HP servers through its support of 6 Gb/s SAS and 6 Gb/s SATA technology, 2 GB FBWC, and advanced RAID capabilities. This controller ships standard with a Smart Array Advanced Pack 2.0 license key and supports up to 227 hard drives.
The HP Smart Array P822 Controller is a low profile, 6 Gb/s, PCIe 3.0, Serial Attached SCSI (SAS) RAID controller that provides enterprise class, second generation storage performance, maximum external scalability, and data protection for select HP ProLiant Gen8 rack servers and tower servers.
It features two internal and four external SAS ports. Advanced storage functionality, including online RAID level migration with flash backed write cache (FBWC), global online spare, and pre-failure warning all result in increased server uptime. Data compatibility gives customers an easy upgrade path to future Smart Array Controllers.
HP Smart Array Advanced Pack 2.0 firmware provides advanced functionality for this next generation of Smart Array controllers, including features such as RAID 1 ADM (Advanced Data Mirroring), making it easier for customers to protect their data.
Increased performance, scalability and data protection, with reduced initial setup time
Up to 3x performance improvement over previous generation, using DDR3-1333 cache memory
Greater scalability for explosive growth with up to 200 drives supported
Long term data retention with 512MB flash backed write cache (FBWC) offered as a standard feature
Support for RAID 0/1, 1+0, 5, 50 (and 6, 60 with upgrade); new predictive spare activation for improved rebuild and maximized uptime
Ideal for servers that require mission critical reliability and high performance:
Seamless upgrades to and from other HP Smart Array controllers.
Storage interface (SAS/SATA)
Two Mini SAS 4i connectors for attachment to internal drive backplanes
Four Mini SAS 4x connectors for attachment to JBODs and external tape drives
6 Gb/s SAS technology delivers up to 600 MB/s per physical link.
6 Gb/s SATA technology delivers up to 600 MB/s for directly attached SATA drives.
Mix-and-match SAS and SATA drives. Deploy drive technology as needed to fit the computing environment.
