Hi guys,
I'm currently in my trail period of v14 before I pay for the upgrade from v12.5.
Most important feature is the performance gain of such a disk as by the VMware Workstation 14 Pro Release Notes
My first tests although are quite disappointing!
Preface
My host is Windows 7 x64 on a Dell Precision 7510 with 8 Core Xeon, 64GB RAM, two NVMe m.2 drives (Samsung 960 Pro & SM951).
I've installed the latest Samsung NVMe driver on the host and everything else is up to date as well.
All guests are up to date and all NVMe disks are shown correctly in the device manager (under the VMWare NVMe Controller).
All my test runs are done with a complete idle host and guest and are repeated a couple of times to ensure consistency.
My first test was done wit the VM on the "old" SM951 NVMe.
The VM/guest is a newly installed Windows Server 2016 with full VMWare tools installation.
I created 4 disks/vmdk with 60GB each:
The performance inside the guest isn't the same as on the host - not even close!
But whats more troubling is, that the SCSI-vmdk outperforms the new NVMe!!
I did another test with the VM/guest on the brand new 960Pro.
The VM is a Windows 7 with just one vmdk as a NVMe:
Here the "loss" is even worse!
It even seems there there is a "cap" in the maximum performance on a NVMe-vmdk, doesn't matter how fast the physical NVMe is.
Does anyone have suggestions for reasons to this test results?
Can/Should I approach VMWare directly with this issue?
Thanks heaps!
