Where Would We Be Without NVMe?

The purpose of the NVMe standard is to replace SCSI-based protocols, like SAS, so memory-based storage systems, like all-flash arrays, can live up to their full potential. Data centers may not need the performance potential of NVMe all-flash systems. But an increasing number of data centers are finding themselves bottlenecked by SCSI. Before NVMe, these data centers were forced to consider proprietary protocols to get around the bottleneck, and if NVMe didn’t become the standard that it has the industry would be a fragmented mess.

Vendors, in an attempt to meet customer demand and without a standard like NVMe, were creating custom drivers that bypassed the SCSI command stack. The problem was the vendor had to write a version of its driver for each operating system or environment (VMware). The data center was heading toward a situation where it would have to buy flash drives from vendors based on which platforms they supported. Standardizing on a single vendor would have been impossible and vendor to vendor flexibility a pipe dream. Flash prices would have remained high, and the use of these SCSI-avoiding technologies would be for a distinct minority of applications.

NVMe calmed the flash waters. Each operating system and environment could create its own NVMe support, and then any vendor with an NVMe drive could work. NVMe isn’t just for corner use cases and is now positioned to take flash performance to the next level, horizontally solving a vast range of performance problems.

Watch On Demand

Twelve years ago George Crump founded Storage Switzerland with one simple goal; to educate IT professionals about all aspects of data center storage. He is the primary contributor to Storage Switzerland and is a heavily sought after public speaker. With over 25 years of experience designing storage solutions for data centers across the US, he has seen the birth of such technologies as RAID, NAS and SAN, Virtualization, Cloud and Enterprise Flash. Prior to founding Storage Switzerland he was CTO at one of the nation's largest storage integrators where he was in charge of technology testing, integration and product selection.
