It seems that NAND flash memory just isn't fast enough to show off the full performance of the latest datacenter networking equipment from Mellanox. They teamed up with HGST at Flash Memory Summit to demonstrate a Storage Area Network (SAN) setup that used Phase Change Memory to attain speeds that are well out of reach of any flash-based storage system. Last year at FMS, HGST showed a PCIe card with 2GB of Micron's Phase Change Memory (PCM). That drive used a custom protocol to achieve lower latency than possible with NVMe: it could complete a 512-byte read in about 1-1.5µs, and delivered about 3M IOPS for queued reads. HGST hasn't said how the PCM device in this year's demo differs, if at all. Instead, they're...
