Serial Attached SCSI: A Universal Interface for Enterprise Storage

Many factors determine a disk drive's ability to meet a storage application's requirements. Capacity, price, sustained data rates, inputs and outputs per second (IOPS), and reliability under an application's operating conditions are all criteria that systems designers and IT mangers must consider when designing storage infrastructure. This white paper will examine these tradeoffs and show how Serial Attached SCSI (SAS) is designed to enable a single storage system to meet a wide range of requirements.
