NVMe is a logical device interface specification for accessing non-volatile storage media attached via a PCI Express bus. The NVMe 1.3 specification has been published, and it introduces several new features:

As with previous updates to the standard, most of the new features are optional but will probably see widespread adoption in their relevant market segments over the next few years. Several of the new NVMe features are based on existing features of other storage interfaces and protocol such as eMMC and ATA. Here are some of the most interesting new features:

Device Self Tests
Boot Partitions
Sanitize
Virtualization
Namespace Optimal IO Boundary
Directives and Streams
Non-Operational Power State Permissive Mode
Host Controlled Thermal Management

    Virtualization - Won't boot

    I think whats going on is they got it on VMWare's VSAN approved devices list.

    I have a small vmware cluster in my basement the stereotypical "home lab" and VSAN requires at least one SSD per host, and I'm using NVMEe SSDs and spinning rust for bulk storage. AFAIK if it works at all, VSAN will use it, but you get the usual corporate song and dance bullshit about "official support" if you actually have support and if you want someone in India to read a script telling you to reinstall or reboot. So its nice to be on the VMWARE hardware compatibility list for VSAN.

    The list doesn't really matter for businesses anyway. My annual license was cheap because I'm in a user group that gets almost free licenses, but businesses pay like $2500 per host for VSAN so coughing up $600 for the "correct" 2 TB SSD isn't a major expenditure.

    For non-vmware people, VSAN is about what it sounds like a virtual SAN thats not exactly an appliance image but is more of a kernel driver implementation (whoa!). If you're familiar with life under LVM on linux, the vsan is like a magical LVM volumegroup.
