At the SC17 show, Micron Tannounced a new 32GB NVDIMM-N offering twice the capacity of existing NVDIMMs, providing system designers and original equipment manufacturers (OEMs) with new flexibility to work with larger data sets in fast persistent memory.

The solution is architected to support the increasing performance, energy efficiency and uptime requirements of data analytics and online transaction processing applications. Compared to server configurations using traditional far storage, deploying NVDIMMs can deliver up to 400 percent performance benefits.
 

 
As data center storage volumes grow, database queries increasingly need key datasets to be retained in-memory to improve access speeds due to the rising business requirement for higher availability. Many businesses are seeing increased value in placing fast memory near the processor to reduce the need to transfer data from far storage.

Persistent memory delivers a unique balance of latency, bandwidth, capacity, and cost by delivering ultra-fast DRAM speeds for critical data. What sets it apart from standard server DRAM is its ability to preserve information in the event of a power loss. Micron’s technology provides a unique solution for near-memory data analysis and addresses rising bandwidth demands of data-rich applications in markets such as finance, medicine, retail, and oil and gas exploration.

NVDIMM has emerged as a critical persistent memory technology due to its ability to deliver the performance levels of DRAM combined with the persistent reliability of NAND. It reduces the bandwidth gap between memory and storage.

Applications which require frequent updates — such as journaling or transactional logging of metadata — now have the capability to leverage NVDIMM for these functions instead of traditional far storage. Micron’s NVDIMM allows customers to raise read-centric performance by 11 percent and write-centric performance by 63 percent for block level data.

"As data sets get larger and larger, data access becomes increasingly critical to application performance,” said Tom Eby, senior vice president for Micron's Compute and Networking Business Unit. “Our new 32GB NVDIMM-N equips system architects with a high-capacity persistent memory solution that can dramatically increase throughput and improve total cost of ownership.”

VMware and Dell are collaborating with Micron to increase the performance for virtualized applications. With virtual persistent memory, customers can now run multiple operating systems in a virtualized environment while reducing overall network traffic.

“As the global leader in cloud infrastructure and business mobility, VMware recognized early the significant reduction of database and local storage latencies that Micron NVDIMM-N can bring to our virtualized customers using Dell PowerEdge servers,” said Richard A. Brunner, chief platform architect and vice president of Server Platform Technologies at VMware, Inc. “Using the 16 GB NVDIMM-N from Micron for the Dell PowerEdge 14G servers, a future version of VMware vSphere(R) intends to efficiently grow the number and size of virtualized persistent memory workloads in the data center while ensuring the benefits of live migration, check-pointing, and legacy storage optimizations for NVDIMM. VMware looks forward to the improvements that can arise when the server industry starts deploying the new 32 GB Micron NVDIMM-N to our customers.”

“Persistent memory solutions enables our customers to optimize intensive database and analytics workloads,” said Robert Hormuth, vice president and fellow, Server Division CTO at Dell EMC. “Micron's advancement in persistent memory offering and Dell EMC engineering efforts to enhance NVDIMM capability of PowerEdge servers will boost application performance, reduce system crash recovery time and enhance SSD endurance for our customers.”
