QLogic joins NVM Express initiative as NVMe Over Fibre spec emerges

NVM Express, or NVMe, is an optimized interface designed specifically for non-volatile memories, such as flash. As detailed in our Defining NVMe article, NVMe offers unparalleled performance over the PCIe bus. The NVMe specification lays the groundwork for the base technology, but complementary technologies are entering development to further enhance its capabilities. One particularly promising specification is the NVMe Over Fiber standard. This allows for end-to-end NVMe over Infiniband, Ethernet with RDMA, and Intel's Omni Scale Fabric.

 

TweakTown image news/4/1/41644_01_qlogic_joins_nvm_express_initiative_as_nvme_over_fibre_spec_emerges.jpg

 

Flash has long been confined inside the server in DAS (Direct Attached Storage) configurations. This keeps the SSD as close to the processor as possible, and eliminates network latency. NVMe Over Fibre offers refined performance by removing the SCSI translation layer, which adds latency when communicating over the network. According to recent surveys, network congestion is the most pressing issue for IT professionals. The NVMe Over Fibre standard will refine communication between clusters, and SSDs can be addressed from remote servers as if the PCIe SSD were plugged directly into the server. Qlogic is one of the leading suppliers of server networking products, and their entrance into the NVM Express consortium will likely speed development and adoption of NVMe Over Fibre as well.

PMC scores win with Lenovo ThinkServer SAS partnership

PMC has announced that Lenovo has selected PMC storage solutions for external connectivity in their ThinkServer product line. Lenovo is offering the Lenovo 8885E by PMC for 12Gb/s SAS applications. The low-profile MD2 form factor 8885E is an HBA that provides eight SAS/SATA ports for connectivity. HBA's are becoming more popular in the datacenter as new architectures arise to leverage scale-out storage and advanced erasure coding. PMC Sierra has been very aggressive on the SAS front and recently captured the goal of providing the most SAS ports on a single card. This has led to a leading position in the market, and PMC has currently shipped more SAS ports than their competitors.

 

TweakTown image news/4/1/41413_01_pmc_scores_win_with_lenovo_thinkserver_sas_partnership.png

 

The increased density has the side effect of lower power consumption per port, which resonates well in power-constrained datacenters. PMC has measured 40% lower power consumption than their competitors with the same number of devices connected, which results in a tangible TCO reduction for their customers. As a rough guideline most datacenters spec each watt of power as an incremental cost increase of $2 dollars per year. When deploying thousands of SAS adaptors this can lead to a staggering amount of increased cost if there is a difference of a few watts per port.
