Next-Gen SCSI: More for Less
Servers using the new generation of serial-attached SCSI hard drives could cost up to 15 percent less than today's standard SCSI systems.NEW YORKServers using the new generation of serial-attached SCSI hard drives will cost up to 15 percent less than todays standard SCSI systems, according to representatives of Hewlett-Packard Co. HP, of Palo Alto, Calif., will transition its various server lines to SAS in mid-to-late 2004, officials said at the here. SAS technology, demonstrated here in prototype drives made by Seagate Technology LLC of Scotts Valley, Calif., and using controllers from Adaptec Inc., of Milpitas, Calif., features 3G-bps connections and dual ports, officials noted. Customers initially will be able to manually configure the ports for failover purposes.
In the 6G-bps SAS 2.0, due in 2005 or later, vendors like HP will offer factory configurations of the ports connected for greater bandwidth. Another doubling of bandwidth will come with SAS 3.0, officials said. Also, the future generations will offer non-volatile cache, they said.
