I’m running my Dell R410 with a SAS 6i/r HBA with a Seagate Constellation ES 2TB SAS Hard drive and I’m having really slow disk performance (10mb/s max) with latency of 40ms and above on both transfers using WinSCP and creating and installing VM’s (note those tests no other VM’s were running).
I am using Dell EMC’s ESXI 6.7U3 image and I recently upgraded from 6.5 because I had the same problem. Am I missing a driver that is slowing me down? If so what one do I need?
It can’t be the disk as I had a pair of Raid 0 160GB Hard drives (not the fastest) and that too was only reaching 10mb/s. I also had an SSD in the system but that would only reach 30mb/s with latency of about 70ms+ so that too was slow.
Any ideas welcome, I’m stumped.
