Serial Attached SCSI (SAS) 12GBPS refers to a specific version of the SAS interface that supports a data transfer rate of 12 gigabits per second. SAS is a data storage interface that is commonly used in enterprise-level servers and storage systems. It is a point-to-point interface, meaning that each device is connected directly to the host, rather than through a shared bus. This allows for faster data transfer speeds and increased reliability compared to traditional parallel SCSI.
