NVMe: Lower Prices, More Features Expand Use Cases

June 4, 2019

The wide adoption of Non-Volatile Memory Express (NVMe) over the last few years has completely revolutionized the storage industry in no small part due to lower prices and better performance. With the introduction of more features, such as management, more enterprises and hyperscale data centers are migrating to NVMe. The introduction of NVMe over Fabrics (NVMe-oF) promises to accelerate this trend for enterprises using a variety of infrastructures.

NVMe is architected with a layered approach, which enables NVMe data...

Nonvolatile memory express (NVMe) has gained incredible adoption as a low-latency interface for connecting host systems with SSDs. NVMe storage attached directly to host systems via peripheral component interconnect express (PCIe) is commonly available in high-end storage servers, laptops, and mobile devices.

A complementary specification, NVMe over fabrics (NVMeoF) defines the attachment of that same NVM storage media over a fabric with microsecond-level latency. The NVMe-oF specification was designed to be agnostic of the underlying transport, and an additional...

The non-volatile memory express (NVMe) storage controller interface continues extending into the data center, on the back of growing requirements for new levels of application performance acceleration. NVMe is typically deployed as direct-attach storage via a Peripheral Component Interconnect Express (PCIe) interface, which bypasses the latency overhead of storage networking but at the same time does not scale. NVMe-over Fabrics (NVMe-oF) is emerging to enable greater scalability with levels of latency that are closer to those of direct-attached storage. As...

The University of New Hampshire Interoperability Lab (UNH-IOL) has expanded its Non-Volatile-Memory-Express-over-Fabric (NVMe-oF) testing capabilities to include NVMe over TCP. Ratified in November 2018, the NVMe/TCP spec adds Transmission Control Protocol to the list of NVMe transport protocols, which previously included Fibre Channel, remote direct memory access (RDMA), and PCIe. “NVMe/TCP adds the most commonly used networking protocol to NVMe,” said David Woolf, senior engineer for data-center technologies at UNH-IOL, in a telephone interview with EE Times. “It will let...

Until a couple of years ago, the best way to test your storage hardware was by using a black box, but now there are more options. The new options are exclusively performed in software, courtesy of Calypso Systems, the Storage Networking Industry Association (SNIA), and maybe soon from the University of New Hampshire's InterOperability Laboratory.

Load-testing software isn't new, but it generally works by running sample data through your network. In the Calypso system, released as a specification via...

DURHAM, N.H., March 13, 2019 – The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based testing and standards conformance services for the networking industry, today announced it has expanded testing capabilities for NVMe with the addition of a new NVMe™ over TCP (NVMe™/TCP) test services. The emergence of NVMe/TCP extends NVMe across the entire data center and utilizes simple and efficient TCP/IP fabric to provide high performance and reduced deployment costs.

NVMe/TCP is an important...

The UNH InterOperability Lab (UNH-IOL) Joins SNIA to Support Interoperability in Storage Networking

February 12, 2019

Durham, N.H., February 12, 2019 -- The University of New Hampshire InterOperability Lab (UNH-IOL), an independent provider of broad-based testing and standards conformance solutions for the networking industry, is excited to announce they recently joined the Storage Networking Industry Association (S NIA ), which leads the storage industry in developing and promoting vendor-neutral architectures, standards and educational services that facilitate the efficient management, movement and security of information. The goal of joining SNIA is to follow initiatives around...

Entering the New Hampshire University InterOperability Lab (UNH-IOL) in November 2018, I was surrounded by servers, network cards, Ethernet cables hanging from the ceiling, and a lot of cool nerdy lab rats—like me. We were there to run the first-ever NVMe Over TCP (NVMe/TCP) plugfest.

This Proof of Concept (PoC) plugfest for the new NVMe/TCP protocol would bring together multiple vendors for the first time to validate their hardware and software implementations, specification compliance, and interoperability against each other....

Kalray, a pioneer in processors for new intelligent systems, is proud to announce that its KTC (Kalray Target Controller) solution has been certified1 by the NVM Express organization through the University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent testing provider of standard conformance solutions and multi-vendor interoperability. This certification, the first of its kind for a fully integrated system, is an important milestone for Kalray. It demonstrates the level of maturity of its KTC data center solution and its...

The next quantum leap in storage technologies is driving the need for faster storage fabrics to transport this data surge. Such an acceleration in storage demand and solutions requires storage transports to provide better overall performance as well as the ability to guarantee Service Level Agreements (SLAs). Of course, the storage solution I’m speaking about Non-Volatile Memory Express (NVMe) and its latest expansion into NVMe over Fabrics.

First some housekeeping. References to NVMe-oF and FC-NVMe are prevalent and cause...
