NVMe transport protocol in Elastic Storage System 3000
The Elastic Storage System 3000 systems uses the Non-Volatile Memory express (NVMe) drive transport
protocol.
• NVMe is designed specifically for flash technologies. It is a faster, less complicated storage drive
transport protocol than SAS.
• The NVMe-attached drives support multiple queues so that each CPU core can communicate directly
with the drive. This avoids the latency and overhead of core-to-core communication, to give the best
performance.
• NVMe offers better performance and lower latencies exclusively for solid-state drives through multiple
I/O queues and other enhancements.
