Hardware Requirements for System Under Test

Jump to solution

Hi Team,

I was reading through the VMMark 3.1 User's Guide and looking for a clarification regarding the VMmark Hardware Requirements for System Under Test.

I understood that the cluster for SUT should have minimum of 2 Hosts (to support Infrastructure operations as well). My question is - Are the CPU/Memory/Storage requirements mentioned in the document (47 vCPUs / 166 GB) per Host (or) cluster? Also, in case, if the CPU/Memory of SUT is lesser than recommended in the document, will there be any errors in the test run?

Thank you,

Krishna

The Datacenter Management Server refers to the HW server where  the VMware vCenter Server Appliance is running.

The statement under Clients section in regards to is 2/1 number mentioned for "Total Number of Virtual Clients / Virtual Client Hosts" is stating there are 2 virtual clients (the Tile Client and the PrimeClient) running on 1 ESXi host.

The 47 vCPUs refers to how many vCPUs are allocated to all the Workload VMs (Weathervane, DVD Store and Standby)  that are created for 1 tile for a VMmark3 run.  It is  possible to run a single tile on the SUT cluster (made up of a minimum of 2 hosts) that has less than 47 logical cores or threads.  On the VMMark3 Results page there is a submission of a single tile run with a 2 host SUT cluster with only 32 logical cores.   https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/vmmark/2019-11-01-Fujitsu-RX1330M4...

Also, for memory you are allowed to overcommit memory (more memory allocated to the VMs then physical memory installed in SUT hosts).

Per the VMmark3 User Guide document:

System Under Test Memory Requirements

Each tile in the VMmark benchmark allocates a total of either 158GB or 166GB of RAM (the RAM required by the prime and tile clients is not included in this total because it’s not part of the SUT; instead it’s addressed in “Memory Requirements for VMmark Clients” on page 35). While memory overcommitment is allowed, it does have the potential to adversely affect the VMmark score.

Thanks Fred for your reply -

I do have one question - I was going through the report from the link provided above (https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/vmmark/2019-11-01-Fujitsu-RX1330M4... ) and observed the following:

  • Under "Servers" section, there are 2 servers mentioned in SUT - I believe these are the ESXi hosts where the Workload VMs will run
  • "Datacenter Management Server" - I believe it is a different ESXi Host where the Prime Client is run.

Are my observations correct?

Also, under "Clients" section, there is 2/1 number mentioned for "Total Number of Virtual Clients / Virtual Client Hosts"  - I did not understand what this is for and how to read it. Can you please clarify this question?

Thank you,

Krishna

Thanks fredab2​ for your reply -

If I understand it right, from the report mentioned above (https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/vmmark/2019-11-01-Fujitsu-RX1330M4... ) , the vCenter Server is running in a seperate server and Clients (Tile Client and Prime Client) are running in a different server (as specs and ESXi versions are different).

Is it a good practice (and is it allowed in VMMark setup) to install vCenter Server as a Virtual Machine in the same ESXi Host as clients?

Thanks,

Krishna

It is allowed to run vCenter server on same hosts as Clients but you can look through a number of submissions and probably see it isn't done by most submitters.
