Mountain View, Calif. - Attacking the market for SCSI storage controllers, 3ware Inc. has rolled out a high-end version of its enhanced ATA adapter card and is sampling a card supporting the emerging serial ATA standard.
The Escalade 7500-12 is a 12-port storage controller claiming the performance and reliability of more-expensive SCSI storage controller cards. A serial ATA version, due this fall, will extend the adapter to support 16 ATA hard drives.
The card is based on a proprietary silicon switch and packet protocol that are said to support operations across multiple drives more efficiently than the shared-bus model of SCSI controllers. The company claims performance gains over SCSI cards in RAID configurations using more than four drives, at a relatively small price premium over existing ATA controller cards.
Due to its switching capabilities, the Escalade 7500-12 requires less buffering than most other ATA and SCSI controllers. It ships with 4 Mbytes of cache. The 12-port card is offered through distribution at a suggested price of $699. 3ware is initially using external PHYs to convert signals from parallel to serial for its serial ATA version. That card will carry a price premium of about $100 and will come in versions supporting four, eight, 12 and 16 ports.
