Samsung Unveils The PM9A3 SSD Featuring Sixth-generation VNAND at OCP Virtual Global Summit
Samsung announced today in an OCP Virtual Summit keynote that it has developed a solid state drive (PM9A3 SSD) with a SNIA-based E1.S form factor and full PCIe Gen 4 support to harness the production efficiencies of the company’s sixth-generation (1xx-layer), three-bit V-NAND.
At the same time, the company said that it has introduced a comprehensive reference design for its E1.S-based storage system.
The keynote, in addition to announcing the PM9A3, highlighted a new approach to open source multi-industry storage collaboration that spotlighted the development of an open-source platform (OSP) fundamentally tied to cloud-scale infrastructure deployments. It was presented by Jongyoul Lee, Senior Vice President of Samsung’s Memory Software Development Team at the Open Compute Project Virtual Global Summit.
“Offering the most 1U server-optimized form-factor, the PM9A3 will improve space utilization, add PCIe Gen4 speeds, enable increased capacity and more,” said Mr. Lee. “We see it eventually becoming the most sought-after storage solution on the market for tier one and tier two cloud datacenter servers, and one of the more cost-effective,” he added.
The E1.S drive form-factor combines major benefits of 2.5-inch U.2 SSDs, with what is widely considered the optimal storage design for 1U servers today. For M.2 SSD users, the E1.S SSD will expand the SSD power budget, accommodate PCIe Gen 4, and allow datacenter managers to add more SSDs per rack-unit.
| Samsung PM9A3 Speeds | Random Reads | Random Writes | Sequential Reads | Sequential Writes |
|---|---|---|---|---|
| E1.S | 900,000 IOPS | 180,000 IOPS | Up to 6500 MB/s | Up to 3500 MB/s |
| U.2 | 900,000 IOPS | 180,000 IOPS | Up to 6500 MB/s | U p to 3500 MB/s |
| M.2 | 550,000 IOPS | 70,000 IOPS | Up to 3500 MB/s | Up to 1750 MB/s |
The newly announced PM9A3 drive, to be available in three versions, is expected to feature a PCIe Gen 4 (x4) interface for more than twice the sequential read performance of PCIe Gen 3 (3200MB/s), and include dedicated hardware accelerators for nearly twice the random writes (180,000 IOPs) of the previous generation. Capacities will range from 960 GB to 7.68 TB.
The PM9A3 SSD’s E1.S design with an industry-standard EDSFF connector is set to enhance the industry’s most popular SSD lineup, one that includes the leading SSD for datacenter applications (PM983).
For datacenters now using U.2 SSDs, the E1.S form factor will allow hardware engineers to add more SSDs per server, freeing up additional 1U space and lowering the total cost of ownership.
Open-source Platform Reference Design
Samsung is also providing a collaborative server reference design to assist datacenter managers in quickly adopting and deploying its E1.S-based storage system.
The reference design, made by Inspur, is now available.
