Serial Attached SCSI Technology Roadmap

  Last updated: September 14, 2021 Notes: This roadmap shows the availability of prototypes and end-user products for each generation of SAS. Plugfest is an event where industry participants test their prototype products to confirm interoperability. End-user products typically become available approximately 12-18 months after the first Plugfest. View / download the PDF version of… Read more »

Serial Attached SCSI

Serial Attached SCSI The industry is gearing up for Serial Attached SCSI (SAS), a new, faster version of SCSI designed to meet the demands of enterprise IT for the coming decade. The SAS interface supports both SAS disk drives for mission critical applications and Serial ATA (SATA) drives for low-cost bulk storage of reference data,… Read more »

Serial Attached SCSI Logos — 3Gb/s

The Serial Attached SCSI logo was created by the SCSI Trade Association (STA) membership to facilitate the identification of the Serial Attached SCSI architecture in the market place. STA has not established a trademark or product compliance program to be associated with the logo. STA assumes those using the logo will do so in a… Read more »

Serial Attached SCSI Cables and Connectors

Serial Attached SCSI Cables and Connectors In the process of defining and standardizing the Serial Attached SCSI technology, the T10 technical and SFF committees have defined cables and connectors to support the many different SAS-based system topologies that can now be developed. These cables and connectors are available today from many suppliers. Additional connectors are… Read more »

Serial Attached SCSI (SAS) Zoning Overview

Author: Tonya Comer, Product Marketing Manager HP Serial Attached SCSI (SAS) incorporates differential signaling, which reduces the effects of capacitance, inductance, and noise experienced by parallel SCSI at higher speeds. SAS links are full duplex (Figure 1); they send and receive information simultaneously, thereby reducing a major source of latency inherent in parallel SCSI. Unlike… Read more »
