Serial Attached SCSI (SAS) Technology
Overview
Serial Attached SCSI (SAS) Technology
SAS is an interface standard that is used predominantly in data center storage ecosystems today. Currently supporting up to 12 Gb/s of throughput per SAS PHY, SAS has a roadmap up to 24Gb/s. SAS topologies are scalable to support a very large number of devices through expanders, allowing multiple host devices to access many SAS or SATA target devices. Additionally, longer cables are supported, enabling connectivity reaches of 10m or more when using optical cabling.
Industry-leading SAS/SATA Solutions
Microsemi’s industry-leading SAS Expanders offer superior signal integrity (up to 9dB better than the SAS specification), port density (up to 68 ports), and the industry’s lowest power consumption (competitive solutions have 20-40% higher power consumption).
Microsemi SAS/SATA RAID and HBA storage boards provide the lowest power solution, using the industry’s first 28nm storage controller silicon (up to 40% more power efficient than other solutions) and the industry’s first high-port density (up to 24 ports on a single storage controller device).
Active Leader in SAS Technologies
Microsemi is active in the Technical Committee T10, administered by the InterNational Committee for Information Technology Standards (INCITS). T10 is responsible for Small Computer System Interface (SCSI) standards and storage interfaces.
Microsemi also belongs to the SCSI Trade Association (STA), which promotes and contributes to the evolution of SCSI. Microsemi is an STA board member, giving us the opportunity to collaborate with other SAS industry leaders, such as Seagate, Amphenol, Western Digital, Toshiba (TAEC), SanDisk, Intel, and Molex. The association’s SAS Plugfest events, hosted at UNH-IOL, allow vendors to test point-to-point connections, related technology standards, and large configurations in order to highlight weaknesses and strengths, to allow for future improvements or the validation of existing methodologies.
