Intel NVMe Controller

== 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 ([http://en.wikipedia.org/wiki/NVM_Express 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 [http://vtricks.com/?p=2018 detailed write-up about NVMe], and he also points out that an NVMe driver is already [https://my.vmware.com/web/vmware/details?productId=351&downloadGroup=DT-ESXI55-VMWARE-NVME-10E030-1VMW available for ESXi 5.5], but needs to be installed separately there."
