Viewing SAS Cards
Serial Attached SCSI (SAS) cards use arbitrated bus technology. Each port contains four
separately-arbitrated lanes. Each lane can perform concurrent IO transactions at
3 Gb/sec. This provides an aggregate port rate of 12 Gb/sec.
A SAS card connects to a SAS enclosure. It is a back-end only connection.
