Word of the Day: NVMe

Word of the Day Daily updates on the latest technology terms | December 25, 2018 NVMe NVMe (non-volatile memory express) is a host controller interface and storage protocol created to accelerate the transfer of data between enterprise and client systems and solid-state drives (SSDs) over a computer's high-speed Peripheral Component Interconnect Express (PCIe) bus. The NVMe specification defines a register interface, command set and collection of features for PCIe-based SSDs with the goals of high performance and interoperability across a broad range of NVM subsystems. The NVMe specification does not stipulate the ultimate usage model, such as solid-state storage, main memory, cache memory or backup memory. NVMe provides an alternative to the Small Computer System Interface (SCSI) standard and the Advanced Technology Attachment (ATA) standard for connecting and transmitting data between a host system and a peripheral target storage device. The ATA command set in use with Serial ATA (SATA) SSDs and the SCSI command set for Serial Attached SCSI (SAS) SSDs were developed at a time when hard disk drives (HDDs) and tape were the primary storage media. NVMe was designed for use with faster media. The main benefits of NVMe-based PCIe SSDs over SAS-based and SATA-based SSDs are reduced latency in the host software stack, higher input/output operations per second (IOPS), and potentially lower power consumption, depending on the form factor and the number of PCIe lanes in use.

Quote of the Day "NVMe over FC, also known as FC-NVMe, represents a critical next step in defining the future of the data center." - Scott Sinclair Trending Terms controller NVMe over Fabrics NVMe over Fibre Channel host bus adapter SAS SSD SATA Learning Center NVMe over FC is happening, and it's time to prepare It will be interesting to see how much NVMe over FC, part of the NVMe-over-Fabrics specification, lowers performance latencies in Fibre Channel SANs. Broadcom preps for NVMe over Fibre Channel with Brocade gear Broadcom ships Brocade 128-port, 32-gig FC switch and director blade, updates SAN management software to ease the way to NVMe over Fibre Channel while waiting for array support. How NVMe technology and NVMe over Fabrics will change storage NVMe technology is beginning to make significant inroads in the data center. The next step for many organizations is for NVMe over Fabrics to establish itself as a predominant networking protocol. Cisco MDS FC Director switches expand with eye on NVMe The 1U Cisco MDS 9148 comes with 24 ports for entry-level SANs Customers can light up to 48 ports in eight-port increments. The MDS 9396T switch has 48 ports and scales in 16-port increments, up to 96 ports. Cisco adds an automated SAN zone to ease transition to 32 Gbps FC.
