Hi

 

SCv3020 with 12 SSD, 12 SAS. 95% of data in SSD.

Two 16gbps brand new Connectrix FC.

Six R630 with emulex 8gb FC running ESXI 6.7U3

6 Volumes. all of them using R10, R5 and SSD only (no SAS profiles)

Although most of time is 3-10ms, vCenter observes 60-70 milliseconds peaks of Read latency from random volumes.

All best practices of ESXI6.7 and SC have been applied.

Dell Support has already checked the machine with no issues found.

I totally have no clue or idea.

Anyone before I lost my mind? Maybe someone knows the best expert of SC then can determine the root cause of this?
