Support

"According to hardware support there is one feature that will become more and more important in the future: the NVMe driver that ESXi 6.0 includes out-of-the-box. NVMe (NVM Express) is a new standard for attaching SSD storage directly to the computer's PCIe bus (instead of through a SATA AHCI interface). This allows for new (much smaller) form factors and much improved performance for SSDs. Patrick Schulz over at vtricks.com has a nice detailed write-up about NVMe, and he also points out that an NVMe driver is already available for ESXi 5.5, but needs to be installed separately there."
