Samsung announced first NVMe PCIe SSD for Dell server

Posted by on Friday, May 23rd, 2014 in SSD NEWs

Samsung is offering its first Non-Volatile Memory express PCIe SSD in the new Dell R920 server.

NVMe an open source standardized low-latency host driver and set, operates over PCIe Gen 2.0 and Gen 3.0 communication protocols. NVMe was designed specifically to optimize the performance of next generation PCIes. NVMe enables variable device throughputs of up to 8 Gb/s per lane through specific PCIe lane architecture.NVMe is an open standard designed to address many of those problems. Non-volatile memory express, also known as NVMe or NVM Express, is a specification that allows a solid-state drive (SSD) to make effective use of a high-speed Peripheral Component Interconnect Express (PCIe) bus in a computer. NVMe operates at the host controller and defines a command set and feature set for PCIe-based SSDs with the goals of increased and efficient performance and interoperability on a broad range of enterprise and client systems. The main benefits of NVMe with PCIe-based SSDs are reduced latency, increased Input/Output operations per second (IOPS) and lower power consumption, in comparison to SAS-based or SATA-based SSDs, through the streamlining of the I/O stack.

Its features include :

•A scalable queue interface. Each core can have multiple queues – handy for virtual machines – and separate submission and completion queues with up to 64k outstanding commands.

•Efficient queuing. The queuing workload is split between the host and the NVMe controller.

•Command arbitration. Commands can be assigned different priorities – admin commands are high priority – to help manage service levels.

•Simple, fixed size commands. Three required I/O commands of fixed length means that lower-cost controllers can handle the SSD’s high performance.

•Data management hints. Helps controllers optimize data placement.

The 1.6TB Samsung SFF-8639 SSD is deliver with a sequential read speed of 3GB/s and random reads up to 750,000 IOPS. It is available today in Dell’s new PowerEdge R920 server. Pricing is not released yet, but expect it to be close to US$1/GB.

The NVMe specification was defined by the Non-Volatile Memory Host Controller Interface (NVMHCI) Work Group, which has expanded to include more than 90 companies in the technology industry. The work group released the 1.0 NVMe specification on March 1, 2011 and the 1.1 specification on October 11, 2012. NVMe reference drivers are publicly available for a variety of operating systems, including Windows and Linux.
