Please check on specific feature support with the distros, e.g. Red Hat NVMe-CLI can be obtained as a package for all the Linux distributions. In Ubuntu: sudo apt-get install -y nvme-cli.
We look at queue depth and fan-out and fan-in ratios. With NVMe they could become a thing of the past, but for now there's still a bottleneck at the storage array NVME's huge queue-handling capabilities potentially offer a straight pass through for I/O traffic - a complete removal of the bottleneck.Hi, I recently got a new dedi with two samsung sm961 NVMe SSDs and I wated to test the write/ read performance. I'm using a Software Raid 1. According to benchmarks, this SSD should write with 2.7 GB/s and read with 1.7 GB/s.
I/O Queue Depth means how many I/O commands wait in a queue to be served. This queue depth (size) depends on the application, driver, OS implementation or the definition of host controller interface’s spec., like AHCI or NVMe and etc.. Comparing to ACHI with a single queue design, NVMe has multiple queues design supports parallel operations.
