Hello All,
We have a DELL Poweredge R550 with RAID 10 and unmodifiable 512 KB block size, and our VMFS have size 1 MB block.
Before we made clone for our SQL server VM , with have no issue with performance , bandwith for internal copy is arrount 100 MB/s
But now on our new VM made by clone, we have 30 MB/s when we do some internal copy .
As we cannot change any block size of our RAID and our VMFS , we are blocked with this low performance , how can we increase this performance , or what is the issue and how we can make a workaround for that
NB : Vmware 7.0, vcenter 7.0 and ressource for our VM is now 180 MB and 32 CPU .
Best Regards
Tovo
