SAN JOSE, Calif.–()–Samsung introduced at the moment in an OCP Digital Summit keynote that it has developed a stable state drive (PM9A3 SSD) with a SNIA-based* E1.S type issue and full PCIe Gen Four help to harness the manufacturing efficiencies of the corporate’s sixth-generation (1xx-layer), three-bit V-NAND. On the identical time, the corporate mentioned that it has launched a complete reference design for its E1.S-based storage system.

The keynote, along with saying the PM9A3, highlighted a brand new method to open supply multi-industry storage collaboration that spotlighted the event of an open-source platform (OSP) essentially tied to cloud-scale infrastructure deployments. It was introduced by Jongyoul Lee, senior vp of Samsung’s Reminiscence Software program Growth Group on the Open Compute Mission Digital World Summit.

“Providing essentially the most 1U server-optimized form-factor, the PM9A3 will enhance house utilization, add PCIe Gen4 speeds, allow elevated capability and extra,” mentioned Mr. Lee. “We see it will definitely changing into essentially the most sought-after storage resolution available on the market for tier one and tier two cloud datacenter servers, and one of many more cost effective,” he added.

The E1.S drive form-factor combines main advantages of two.5-inch U.2 SSDs, with what’s extensively thought-about the optimum storage design for 1U servers at the moment. For M.2 SSD customers, the E1.S SSD will broaden the SSD energy funds, accommodate PCIe Gen 4, and permit datacenter managers so as to add extra SSDs per rack-unit.

The newly introduced PM9A3 drive, to be out there in three variations**, is predicted to characteristic a PCIe Gen 4 (x4) interface for greater than twice the sequential learn efficiency of PCIe Gen 3 (3200MB/s), and embody devoted {hardware} accelerators for practically twice the random writes (180,000 IOPs) of the earlier technology. Capacities will vary from 960 GB to 7.68 TB.

The PM9A3 SSD’s E1.S design with an industry-standard EDSFF connector is ready to boost the {industry}’s hottest SSD lineup, one that features the main SSD for datacenter functions (PM983).

For datacenters now utilizing U.2 SSDs, the E1.S type issue will permit {hardware} engineers so as to add extra SSDs per server, releasing up extra 1U house and decreasing the entire price of possession.

Open-source Platform Reference Design

Samsung can also be offering a collaborative server reference design to help datacenter managers in rapidly adopting and deploying its E1.S-based storage system.

The reference design, made by Inspur, is now out there.
