Fibre Channel-NVMe-2 Standard is published

The Fibre Channel Industry Association (FCIA) says that the International Committee on Information Technology Standards (INCITS) has published the FC-NVMe-2 standard developed by the T11 Technical Committee. FC-NVMe-2 enhancements include Sequence Level Error Recovery (SLER), significantly increasing the speed at which bit errors are detected and recovered during data transmission.

“The FC-NVMe-2 standard is focused on allowing bit errors to be detected and recovered at the transport layer before the protocol layer knows anything is amiss,” said Mark Jones, president, FCIA, and director, Technical Marketing, Broadcom Inc. “As link speeds continue to increase to meet the growing volumes of data, detecting errors in microseconds with little or no impact on storage performance becomes increasingly important.”

Fibre Channel continues to evolve in lockstep with the storage-networking requirements of both traditional application environments and newer workloads associated with technologies such as AI, machine learning, and big data analytics. Market analyst and research firm Quillin Research estimates by the end of 2020 over 142M ports of Fibre Chanel will have shipped, and 37M Fibre Channel ports are in use today.

“Fibre Channel does a great job of delivering data reliably whether the data packets are SCSI or NVMe,” said Casey Quillin, principal analyst, Quillin Research. “The SLER feature in FC-NVMe-2 will result in better error handling and recovery, building a stronger foundation with even more reliability for NVMe over Fabrics.
