What is the Zoned Namespace Specification?
June 2, 2021
In mid-2020, the NVMe Organization released the first revision of the Zoned Namespace specification (ZNS). This new specification has received a lot of attention, with promises of longer living drives that achieve higher performance under certain conditions. Since then, a number of companies have published roadmaps that include products with ZNS support. In this article, we'll review the significance of this specification and what ZNS drives are good for.
First, this specification is significant because it brings a new...
The UNH InterOperability Lab Forges Ahead with Multi-vendor Interoperability through NVMe® Specification Virtual Test Events
February 2, 2021
Durham, N.H., February 2, 2021 -- The University of New Hampshire InterOperability Lab (UNH-IOL), an independent provider of broad-based testing and standards conformance solutions for the networking industry, today announced the completion of its second virtual multi-vendor plugfest focused on NVM Express® (NVMe®) and NVMe® over Fabrics (NVMe-oF™) technology test cases across eight unique devices and companies.
The UNH-IOL has been a pioneer in hosting Plugfests , or group test events, since its inception back in 1988....

How the OCP NIC 3.0 is Making Hyperscale Data Centers Cooler
September 20, 2019
Managing and storing more data has forced hyperscale data center companies to reexamine not just how they build a data center but also the thousands of servers housed inside – including the connectors for server components.
Hyperscale data centers have the purchasing power and platform to work directly with manufacturers and engineer the optimized server. Rather than figuring out how to use the latest widget designed for the mainstream data center market, hyperscale data center companies are designing the...

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...
What is NVMe-oF interop testing and why is it important?
May 2, 2019
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...
Validating the Developing Standards of NVMe
April 30, 2019
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...
UNH-IOL Adds NVMe over TCP Testing
March 14, 2019
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...
