3ware introduces new raid controllers

AMCC today introduced a new line of PCI-Express RAID controllers, the 9650SE PCI-Express to SATA II RAID controller.

The 3ware 9650SE offers the most comprehensive line of PCI Express controllers, available in both low profile and half card footprints with 2, 4, 8, 12, 16, and 24-port configurations. The 2 port and 24 port cards are a first for 3ware. All 4-port and above models feature 3ware's Multi-lane connectivity. The 9650SE supports RAID levels 0, 1, 5, 6, 10, 50, Single Disk, and JBOD.

RAID 6 eliminates the risk of data loss if a second hard disk drive fails while the RAID array is rebuilding. In a 3ware RAID 6 system, two sets of parity are simultaneously calculated, written, and rotated across all the drives. This second parity calculation enables the array to survive up to two drive failures without losing data, significantly improving fault tolerance. The 3ware parallel XOR RAID 6 parity generation algorithm maximizes RAID 6 throughput, so that RAID 6 enabled 9650SE controllers deliver unequaled RAID 6 performance. The 9650SE can get up to 700MB/s read speed and up to 600MB/sec write speed in RAID 6.

AMCC's Multi-lane high bandwidth SATA connection system is fast, secure, simple, and clutter free. Multi-lane combines four SATA ports into a single locked connection. Four lanes of high speed SATA traffic travel through just one cable, significantly reducing the number of cables needed to connect controllers, backplanes, and standard SATA drives. With this Multi Lane system a 16 disk setup would only require 4 cables, as where other solutions would require 16 cables.
