OCP Summit: PM883 8TB 2.5-Inch 6Gb SATA SSD From Samsung

Samsung Electronics Co., Ltd.  is rolling out its PM883, a high density datacenter SATA drive, at 8TB.

This SSD offering is a first datacenter SATA drive to incorporate LPDDR4 DRAM modules and features a 6Gb 2.5-inch SATA interface.

The PM883 is expected to accelerate a transition in many existing enterprise datacenters to SATA-formatted SSD designs, with improved economies of scale through the use of advanced-generation V-NAND technology at higher densities.

“We are thrilled to have the opportunity to enable a high level of storage density with low power consumption, which thanks to the efficiency of our 64-layer V-NAND-based technology, allows us to double the capacity of current SATA storage,” said Jim Elliott, corporate SVP, memory sales and marketing, Samsung Semiconductor, Inc. “Our expanded lineup for the PM883 will offer up to 8TB to allow optimal use in existing enterprise and cloud storage systems.“

The PM883 includes 16Gb LPDDR4 DRAM based on 10-nm-class process technology. Also, for the first time in the industry, a SATA 3.3-compliant Power Disable (PWDIS) feature allows power management in individual SSD units to maximize the energy efficiency of datacenters.

With additional power-saving technology, the new drive uses only 2.8Wof power when reading, and 3.7W when writing.

The PM883 reads data sequentially at up to 550MB/s and sequentially writes at up to 520MB/s. Random reads deliver up to 98,000 IO/s and random writes up to 28,000 IO/s.

Regarding endurance, the PM883 has a TBW (total bytes written) rating of 5466TB for the 3840GB drive and 10,932TB for the 7680GB drive.

In related enterprise memory news, the company announced that it will exhibit two new or upcoming memory solutions key to the HPC market – the first 8TB SSD built in the anticipated ultra-small NF1 form factor, and the first 64GB DDR4 RDIMM using 16Gb monolithic chips.

NF1 SSD exhibition
The firm’s NF1 (formerly referred to as NGSFF), which has been designed to improve the storage capacity and performance of next-generation 1U rack servers, was exhibited for the first time at the 2018 Open Compute Project U.S. Summit in the San Jose Convention Center.

The 8TB SSD is  being sampled with several server manufacturers, including two who was co-exhibiting in the company’s booth. The drive will have the first form factor designed specifically for the dense 1U servers widely used in cloud datacenters.

The upcoming company’s 64-layer 8TB NF1 SSD can deliver I/O at a 0.5 TB/s.

Measuring 30.5x110x4.8mm, the drive will improve space utilization and scaling options for artificial intelligence, deep learning and other hyper-scale datacenter server applications. Up to 36 NF1 SSDs can fit across the front of a 1RU server allowing nearly six times the storage capacity per RU over U.2 SSDs.

16Gb 64GB DDR4 RDIMM exhibited
The company also exhibited a 16Gb-based 64GB RDIMMs at the 2018 OCP U.S. Summit, for cloud or enterprise servers.

Available, these low-power monolithic chips support interface speeds of 2,666MT/s, and offer a greater than 20% power reduction versus 8Gb-based 64GB LRDIMMs. Use of the 16Gb monolithic chips allows the maximum DIMM density to increase to 256GB making them suitable for memory-intensive applications such as In-Memory Databases and VDI (VDI).

The firm plans to expand its lineup to include higher capacity 16Gb-based 128 and 256GB RDIMM and LRDIMMs later this year.
