PCI express (PCIe) solid state drives (SSDs) offer significant performance benefits in enterprise applications versus traditional hard disk drives (HDDs), as well as SSDs with a legacy storage interface. By realizing the full performance potential of flash memory, PCIe SSDs accelerate I/O-intensive enterprise applications, such as data mining, online transaction processing (OLTP), and financial transaction processing. The strong need for high-performance PCIe SSDs is underlined by the growing performance gap between processors and storage subsystems. Until recently, however, the lack of a host control interface standard has inhibited the widespread adoption of PCIe SSDs. Existing solutions have required proprietary software drivers that complicate OEM qualification, inhibiting broad adoption of PCIe SSDs.
With the emergence of non-volatile memory express (NVMe), a scalable host controller interface specifically developed for PCIe SSDs, and a supporting ecosystem plus dedicated devices such as NVMe programmable flash controller chips, the potential of PCIe SSDs for enterprise computing applications can be fully realized. Device programmability will allow SSD suppliers to lead an industry transition to NVMe PCIe SSDs while still being able to differentiate products through their own firmware. Server and storage OEMs meanwhile, will benefit through dramatically improved performance and greatly simplified and expedited qualification processes.
