SQLIO Performance tests of a 2 TB Intel P3700 NVMe PCIe SSD on a Dell r710
View Notes.txt
Notes: this is on a Dell R710 server running Windows 2012 Server Core (latest patches as of 2014-10-12) - access to NVMe drives is via a mini driver on this OS version.
We'll re-run these tests when these SSDs migrate to some new R730xd servers in about a month, when we rebuild the cluster on Windows 2012 R2 which has native NVMe support.
This is also in a currently inactive server while we do a burn-in test on the primary to ensure there are no issues with this storage setup. If you have additional SQLIO test configurations you want to see - ping me via @Nick_Craver and I'm happy to run when until we stick this into production on 2014-10-14 (2 days from now).
