SPECIAL FEATURE
Get to know NVMe and how it meets the demands of ever-increasing storage needs. By John Reardon, Editor Introduced in 2012, the Non-Volatile Memory Express (NVMe) quickly replaced the older SATA Solid State Drive (SSD) for storage solutions. The increased performance for high bandwidth data and lower latency better supported the current generation of NAND flash memory. Running on PCIe serial bus data rates increased to 3 Giga Bytes per second with seek times significantly faster. The approach of NAND flash acceleration via the PCIe interface used in NVMe protocol is not the first industry attempt to benefit from PCIe transfer speeds in data storage devices. But what made NVMe so successful is a direct connection between the NAND controller and host processor without unnecessary data protocol translations. NVMe is built upon x4 gen3 (8 Gb/s) PCIe lanes connection, which results in 32 Gb/s of theoretical maximum data transfer rate.
OSS - Provide up to 200TB high-density PCIe NVMe flash and support up to 8 million IOPS with 80GB/second throughput. Many of our Storage Arrays are based on the Ion Accelerator Software.
The use of NVMe will invariably increase the performance of a system over previous technologies. But not all sources are created equal. For example, the Toshiba RC100 reads at 1.2 GBps and writes at just less than 900 MBps, while Samsung’s 970 Pro exceeds the 3GBps and writes at over 2.5GBps. Speeds variations can also occur with improper configuration and or insufficient cache.
