Persistent Memory over Fabric Technology by Plexistor

Plexistor Ltd. announced a breakthrough in using persistent memory over fabric (PMoF).

Persistent memory can now be dis-aggregated and shared across multiple servers using company’s PMoF Brick running on commodity hardware. PMoF makes it possible to achieve near-memory speed and operational simplicity without sacrificing persistency.

Benchmarks performed on a Mellanox Technologies, Ltd. ‘s infrastructure over 100GbE using firm’s PMoF Brick demonstrated record performance: more than 1.6 million random 4KB IO/s at less than 6µs with throughput of 7GB/s. This is over an order-of-magnitude better than the recently announced rack-optimized flash storage DSSD appliance, which offers 100µs latency.

PMoF Brick architecture is designed to utilize emerging persistent memory technologies, such as Intel Corp.‘ Optane, providing higher performance for workloads like NoSQL databases and big data analytics. The solution also leverages traditional flash technologies and auto-tiering software in order to provide a cost-effective solution for the enterprise.

“Those who follow the evolution of memory will find that our PMoF Brick is a stunning development for the new in-memory workloads, as well as unprecedented low latency” said Sharon Azulai, CEO, Plexistor. “In businesses and industries where ‘fast’ means an increase in revenue, the PMoF Brick technology can change the economics of enterprise computing.”

Working with Mellanox, the company demonstrated it can handle millions of remote writes per second at latencies as low as a few microseconds utilizing Mellanox ConnectX4 NIC and a Spectrum switch. This advancement in persistent memory dis-aggregation offers lower costs and simpler management than other available architecture capable of delivering equivalent performance.

“We are excited to be the first to demonstrate how persistent memory fits in the Rack-Scale Design (RSD),” said Dr. Amit Golander, CTO, Plexistor. “Our collaboration with Mellanox proves that PMoF is a very viable solution for efficient utilization of shared resources to deliver both low latency and ease of operations.”
