NVM Express over Fabrics

NVMe-oF (NVM Express over Fabrics)

Cavium QLogic adapters enable NVMe over Fibre Channel and RDMA capable Ethernet Fabrics


What is NVMe?

NVM Express (NVMe) is a new and innovative method of accessing storage media and has been capturing the imagination of data center professionals worldwide. NVMe is an alternative to the Small Computer System Interface (SCSI) standard for connecting and transferring data between a host and a peripheral target storage device or system. SCSI became a standard in 1986, when hard disk drives (HDDs) and tape were the primary storage media. NVMe is designed for use with faster media, such as solid-state drives (SSDs) and post-flash memory-based technologies. NVMe provides a streamlined register interface and command set to reduce the I/O stack's CPU overhead by directly accessing the PCIe bus. Benefits of NVMe-based storage drives include lower latency, deep parallelism and higher performance.

What is NVME over Fabrics (NVMe-oF)?

With up to 200Gbps of Ethernet line rate throughput and 256Gb Fibre Channel line rate throughput, the FastLinQ 45000 series and 2700 Series Gen 6 Fibre Channel technologies offers intelligent offloads that enable low latency NVMe SSDs to scale out to the network in the most efficient way possible, simplifying design, reducing overhead and improving performance.

FC-NVMe

Next-generation data intensive workloads are utilizing low latency NVMe flash-based storage to meet ever increasing user demand. By combining the lossless, highly deterministic nature of Fibre Channel with NVMe, FC-NVMe delivers the performance, application response time, and scalability needed for next generation data centers, while leveraging existing Fibre Channel infrastructures. QLogic 2690 Series of Enhanced Gen 5 and 2700 Series of Gen 6 Fibre Channel adapters FC-NVMe ready.

NVMe over Ethernet RDMA

Cavium QLogic is one of the leaders driving the ecosystem with the goal of extending the reach of NVMe's low latency and high performance capabilities beyond the server and across the network to access remote storage. Due to the performance demands of NVMe, high performance and low latency networking is required and Ethernet based RDMA — RoCE, RoCEv2 or iWARP are the leading choices. QLogic FastLinQ 45000 Series 10/25/40/50/100GbE adapters support Universal RDMA (RoCE, RoCEv2 and iWARP) and deliver the ultimate choice to customers for scaling out NVMe over a general purpose Ethernet fabric.
