Adaptec unifies SAS, Serial ATA

Later this month, Adaptec will introduce what it calls its first Unified Serial host bus adapter. The cards can support a mix of as many as 128 Serial Advanced Technology Attachment and Serial Attached SCSI (SAS) drives.

"It delivers the value of [Serial ATA] connectivity and the performance scalability of SAS," said Suresh Panikar, Adaptec's director of worldwide marketing.

The company will offer two models, both under the Series 1 moniker. The Adaptec 1405 has four internal ports, and the Adaptec 1045 has four external ports. Plugged into a PCI Express x4 bus, either card can support as many as 128 storage devices, thanks to the SAS and Serial ATA architecture. The cards promise a throughput of 800 megabytes/sec, and they support Redundant Array of Independent Disks configurations. The 1405 lists for $160, and the 1045 lists for $190.

Organizations can incorporate the drives into file or print servers or as part of a backup system, eliminating the need for a stand-alone storage-area network. Using all 128 connections, a system could support as much as 100T in a single configuration, Panikar said. The drives could also be used for tape libraries that support Serial ATA and SAS commands.

The company will provide drivers for Microsoft Windows, FreeBSD, and Red Hat and Novell distributions of Linux.
