HP Smart Array 6400A (SA6400A) Controller Quick Specs
The SA6400A is a high-performance Ultra320, PCI-X array controller. It provides maximum performance, flexibility, and reliable data protection for HP OpenVMS AlphaServers through its unique modular design and support for Advanced Data Guarding (RAID ADG). This new generation Smart Array controller again raises the standards of performance, introducing a Double Data Rate (DDR) battery-backed write cache architecture and a new RAID engine.
This controller is ideal for workgroup, departmental, and enterprise servers. And like other Smart Array controllers, the SA6400A features complete data compatibility with previous generation’s Smart Array controllers for easy data migration from server to server and for controller upgradability*
Advanced Data Guarding (RAID ADG) offers breakthrough level of fault protection of RAID volumes up to 1TB and a total of 28 disk drives in a RAID volume. RAID ADG provides fault protection greater than RAID 1 or RAID 5 and only consumes the capacity of 2 disk drives for distributed parity data. RAID ADG protects against any 2 disk drive failures. This higher level of protection is ideal to protect large logical volumes and with high capacity disk drives where a failed drive rebuild time may be significant.
High-performance, Sixth generation architecture offers a new hardware RAID engine, and a new performance 266MHz DDR memory architecture for increased performance over previous controllers.
Recovery ROM protects against a ROM failure or corruption. Ultra320 SCSI technology delivers high performance and data bandwidth up to 320 MB/s bandwidth per channel
