NVDIMM Special Interest Group

**NEW** NVDIMM SIG creates the NVDIMM Cookbook!

*Non-Volatile DIMMs, or NVDIMMs, have emerged as a go-to technology for boosting performance for next generation storage platforms. The standardization efforts around NVDIMMs have paved the way to simple, plug-n-play adoption. If you're a storage developer who hasn't yet realized the benefits of NVDIMMs in your products, then this SNIA tutorial is for you! We will walk you through a soup-to-nuts description of integrating NVDIMMs into your system, from hardware to BIOS to application software. We'll highlight some of the "knobs" to turn to optimize use in your application as well as some of the "gotchas" encountered along the way.

The NVDIMM Special Interest Group (NVDIMM SIG) has been formed to accelerate awareness and adoption of Non-Volatile Dual In-line Memory Modules (NVDIMMs) in the marketplace by:

  • Providing education on how system vendors can "design-in" NVDIMMs.
  • Communicating existing industry standards, and areas for vendor differentiation. 
  • Helping technology and solution vendors whose products integrate NVDIMMs to communicate their benefits and value to the greater market. 
  • Developing vendor-agnostic user perspective case studies, best practices, and vertical industry requirements to help end user customers understand how products and solutions can meet performance, cost, and efficiency goals.

The NVDIMM SIG is a member communiity under the SNIA and the Solid State Storage Initiative (www.snia.org/forums/sssi), which will provide logistical and promotional support for the SIG.

The NVDIMM SIG includes vendors AgigA Tech, Calypso Systems, Diablo Technologies, Fujitsu, HGST, IDT, Inphi, Intel, Micron, Netlist, OCZ, Paper Battery, Samsung, SanDisk, SK Hynix, SMART Modular Technologies, Toshiba, and Viking Technology.

On this page, you will find up-to-date news, event listings, webcasts, FAQs, white papers, and articles about NVDIMMs.  Scroll down the page and see a wealth of educational content on this important topic.

Your feedback is welcome and encouraged.  If you would like to participate in SIG activities, email nvdimmsigchair@snia.org.



JEDEC Announces Support for NVDIMM Hybrid Memory Modules
JEDEC's JC-45 Committee has approved the first standards for support of “hybrid” DDR4 memory modules which are defined as modules that plug into standard dual in-line memory module (DIMM) sockets and appear like a DDR4
SDRAM to the system controller, yet contain non-volatile (NV) memories such as NAND Flash on the module. The press release linked above features a quote from the Co-Chairs of the NVDIMM SIG.

NVDIMM SIG honored by peers at SNIA 2015 Symposium, winning the award for most significant contributions by a SNIA committee in 2014.

Storage in the DIMM Socket
This tutorial focuses on how IT managers have begun seeking out new ways for flash to be deployed in the data center in order to take greater advantage of the performance and latency benefits. With traditional interfaces such as SAS, SATA and PCIe already taking advantage of flash and deployed, the focus has shifted to non-traditional interfaces in order to further penetrate current infrastructure. This has led to the emergence of new solutions that leverage the DDR3 interface, utilizing existing DIMM slots in server hardware
