Milestone signals SCSI Express products are in development and moving forward

SAN FRANCISCO – February 4, 2014 — In a move that punctuates the importance of technical standards including interoperability, investment protection and improved quality for end users, the SCSI Trade Association (STA) today announced the T10 Technical Committee completed and forwarded the first version of the SCSI Express specifications to the InterNational Committee on Information Technology Standards (INCITS) in November 2013. The SCSI Express specifications include the SCSI over PCI (SOP) and PCI Express (PCIe) Queuing Interface (PQI) technical standards.

Targeted at data applications such as financial trading, databases, virtualization servers and other high-throughput applications that require lower latency from critical data storage, SCSI Express is an emerging storage interface that runs commands over a PCIe link. It combines the enterprise-proven SCSI command set with the low latency of PCIe to create a powerful enterprise-class interface for the high-performance capabilities of SSD/flash storage.

“While SCSI commands have been transported across PCIe for quite some time, implementations were vendor unique,” said Marty Czekalski, president of the SCSI Trade Association and Interface and Emerging Architecture Program manager, Seagate. “SCSI Express provides a standardized method for transporting the SCSI protocol across PCIe. Being the most predominate storage protocol, SCSI not only provides a robust ecosystem to PCI Express storage, it protects the technology investment in today’s datacenters.”

Today’s announcement from STA is a milestone in the development of SCSI Express and signals SCSI Express products are in development and moving forward.
