Promise Technology has announced the release of its non-caching ATA RAID 0, 1, 0+1 card and hot swap kit for Ultra ATA/100 drives, that support hot swap under a four-drive RAID 0+1 array. Promise Technology products are available locally through distributor Memtek-MMW.
Designed for small office and departmental servers with higher data capacity requirements than two-drive RAID 1 delivers, the FastTrak100 TX4 PCI card houses four independent data channels designed for a total of four standard Ultra ATA/100 hard drives. The TX4 Pro kit bundles the four-channel RAID card with four SuperSwap hot swap removable drive chassis, designed for continuous PC operation of a RAID 0+1 array when a drive fails.
When used with SuperSwap drive chassis, TX4 permits users to replace a failed drive using two-drive RAID 1 or four-drive RAID 0+1 arrays without shutting down the PC. Users simply slide out the SuperSwap chassis housing the failed drive, replace the drive, and slide the chassis back in. In addition to supporting hot swap of a RAID 0+1 array, TX4 also supports hot swap of two independent RAID 1 arrays.
Says Gary Naidoo, product manager at Memtek-MMW: "TX4 is the newest addition to the Promise line of ATA RAID products - the FastTrak100 TX2, TX2 Pro and LP (low profile) ATA RAID PCI cards and kits."
Compatible with 66MHz PCI bus motherboards, the FastTrak100 TX4 offers data transfer rates in RAID 0 (striping) of up to 200MBps, depending on the number and type of drives used in the system. In addition to RAID 0+1, TX4 enables users to configure RAID arrays in RAID 0 (striping) and RAID 1 (mirroring) arrays.
"TX4 is set to satisfy the needs of business customers wanting run high performance, higher capacity entry-level servers 24x7," explains Naidoo. "It offers the speed of striping with the fault tolerance of mirroring and continuous operation of hot swap support."
TX4 and TX4 Pro support both hot spare and hot swap for 24/7 operations. The card supports Windows 2000/NT4/Me/98/95, RedHat Linux 6.2/7.0, and Netware 5.x.
