Samsung Electronics is rolling out ithe PM883, an 8TB datacenter SSD, which uses LPDDR4 DRAM modules and features a 6.0-gigabits-per-second (Gbps) 2.5-inch SATA interface.
The PM883 includes 16Gb LPDDR4 DRAM based on 10-nanometer (nm)-class process technology. Also, for the first time, 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 2.8 watts of power when reading, and 3.7 watts when writing, according to Samsung.
The PM883 reads data sequentially at up to 550 megabits per second (MB/s) and sequentially writes at up to 520MB/s. Random reads deliver up to 98,000 IOPS and random writes up to 28,000 IOPS.
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, Samsung also announced that this week it will exhibit two new or upcoming memory solutions key to the High-Performance Computing (HPC) market - the first 8-terabyte SSD built in the ultra-small NF1 form factor, and the first 64GB DDR4 RDIMM using 16Gb monolithic chips.
The Samsung NF1 (formerly referred to as NGSFF), which has been designed to improve the storage capacity and performance of 1U rack servers, will be exhibited at the 2018 Open Compute Project U.S. Summit in the San Jose (CA) Convention Center. The Summit will be held March 20-21.
The 8TB SSD is now being sampled with several server manufacturers, including two who are co-exhibiting in the Samsung booth. The drive will have the first form factor designed specifically for the dense 1U servers widely used in cloud datacenters.
The upcoming Samsung 64-layer 8TB NF1 SSD can deliver I/O at a phenomenal 0.5 petabytes per second.
Measuring only 30.5mm x 110mm x 4.8mm, the drive will improve space utilization and scaling options for artificial intelligence, deep learning and other hyper-scale datacenter server applications. Up to 36 Samsung NF1 SSDs can fit across the front of a 1RU server allowing nearly six times the storage capacity per RU over U.2 SSDs.
Samsung will also be exhibiting the first 16Gb-based 64GB RDIMMs at the 2018 OCP U.S. Summit, for cloud or enterprise servers.
Available now, these low-power monolithic chips support interface speeds of 2666 MT/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 Virtual Desktop Infrastructure (VDI).
Samsung plans to expand its lineup to include higher capacity 16Gb-based 128GB and 256GB RDIMM and LRDIMMs later this year.
