This week the National Association of Broadcasters (NAB) show is going full swing in Las Vegas and Ethernet Technology Summit (ETS) is running in Santa Clara, California. Today in the United States also happens to be Tax Day, when you must file your return and pay any extra taxes owed to the US Government. That makes it a great time to show a new solution that aims to eliminate latency “taxes” from flash storage—it’s called NVMe Over Fabrics.
What Is NVMe and Why Would I Want It?
First a brief history of NVMe (Non-Volatile Memory Express): Traditionally flash storage is connected by SAS or SATA disk interfaces or a PCIe slot with proprietary drivers. SAS and SATA are proven solutions but they—and the included SCSI protocol layer–are designed for spinning disk, not flash. NVMe standardizes a flash-optimized command set to access to flash devices over a PCIe bus, eliminating the SCSI latency tax. NVMe devices are shipping now with native drivers for Linux, Windows, and VMware.
