What could be causing (and how to fix) my tempdb files (8 equal size) to have [avg_write_stall_ms] of 7300ms and the next highest data file is 47ms.
System is Hyper-V fail-over cluster, SQL 2012 Standard, 60GB RAM, 20 vCPU, EqualLogic PS6100 SAN
Here's my results from the Glen Berry tools
I've requested that the tempdb data files be moved to their own drive letter, but am not sure that will help because it would be the same SAN.
