 Serial Attached SCSI (SAS) is a quickly growing storage media that uses SAS and⁄or SATA drives in the same storage network depending on the need.
Serial Attached SCSI is the next step up from SATA desktop storage accommodating both low-cost, high-capacity SATA disk drives as well as long-life, high-performance SAS drives. This ability to support two classes of drives offers users and systems storage integrators new levels of flexibility in designing, scaling, and managing disk arrays. In fact, the key advantage of SAS is choice. Implementing SAS lets users meet performance, capacity, and reliability requirements while being able to employ legacy SCSI software and mix-and-match SAS and⁄or SATA drives.
SAS cards can manage huge arrays of drives using enclosures with expanders built in. SATA drives may be used in SAS networks for large inexpensive storage or backup for the best GB per dollar. For the best in data security use the highly rated SAS drives.
The New 6G SAS enclosures are now available. If you’re running an older 3G SAS card please stick with the 3G style expander enclosures. Use 6G expanders if you're running the newer 6G SAS cards. Do not mix and match within a system. If you're using a Mini-SAS enclosure that doesn't have a built in expander any enclosure will work with any card.
