To all VMmark Benchmark Submitters,
This is a notice to inform you of a limitation when running VMmark 3.x with vSAN.
vSAN OSA (all releases) and vSAN ESA (8.0U1 and older) have a limit of 200 VMs per host.
This equates to roughly 10.5 tiles per physical host in the cluster.
19 VMs per tile x 10.5 tiles = 199.5 VMs
For example, a 4-host vSAN cluster would have a limit of 42 tiles.
42 tiles is a total of 798 VMs, which is an average of 199.5 VMs per host.
Any additional tiles would exceed the maximum supported by vSAN and would be disallowed by the VMmark 3.x Run & Reporting Rules.
We realize that during the VMmark benchmark run it is theoretically possible that one or more hosts might exceed 200 VMs at some point during the run.
This is very difficult to control, and even more difficult to record and quantify. For this reason we will focus on the average number of VMs per host. As long as the average number of VMs per host stays within the documented supported maximums, the benchmark submission will be considered compliant on this point.
At this time the supported maximum number of VMs per host are as follows:
200 VMs per host: vSAN OSA all versions, vSAN ESA 8.0 and vSAN ESA 8.0U1
500 VMs per host: vSAN ESA 8.0U2 and later
For more information, please see the vSAN Limits section of the vSAN Design Guide.
Thank you,
The VMmark Team
