Serial Attached SCSI (SAS) Interface
A drive with a SAS (Serial Attached SCSI) interface can be linked directly to controllers. The SAS interface offers the following advantages over the traditional SCSI
interface:
l SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables.
l Its full-duplex signal transmission supports up to 6.0 Gb/s.
l SAS drives can be hot-plugged.
