Samsung lifts lid on 1.6TB flash whopper spaffing data at 3GB/s

NVMe stands for Non-Volatile Memory Express, and is a standardised protocol for applications to access data stored on PCIe-connected SSDs via a software driver. Currently each PCIe SSD on the market has its own data access protocol and needs its own specific driver. By standardising on the NVMe protocol, only one host operating system driver is needed to access any manufacturer's NVMe-compliant SSD.

This product has some amazing specs. Does SL6 have driver support for NVMe? If not, when can we expect to get such a driver?

From what I've read, it looks like NVMe was added to kernel 3.3. Unless this is backported to the upstream (RHEL) kernel, SL6 (2.6.32) will not have it. But it will most likely be in RHEL/SL-7.

If you wish to test the performance of NVMe on SL6, I suggest you install kernel-ml from ELRepo. Its version is 3.10.x at this moment.

Red Hat 6.5
QUOTE

Red Hat Enterprise Linux 6.5 stays current with the advancements in Solid-State Drive (SSD) controller interface, introducing support for NVM Express (NVMe)-based SSDs. The NVMe specification aims to standardize the interface for PCIe-based SSDs and its inclusion in Red Hat Enterprise Linux 6.5 positions the platform to support an expanding range of future NVMe-based devices.
