Managing Access Control Through SAS Zoning

Serial Attached SCSI (SAS) is gaining popularity in small storage area network (SAN) server environments. With its rise in popularity comes the need to segregate and manage device traffic in a similar fashion to what is already done in larger Fibre Channel networks by using zones or in Ethernet using virtual LANs. By doing this, IT administrators can create much more flexible, scalable, and efficient server networks that meet their business needs. SAS zoning, a proposal to the T10 Technical Committee for inclusion in the SAS-2 specification, provides this capability. (September 2005)
