vapp hardware platforms

[ServiceOptimi]

All,

I am learning that the hardware platform 7 for the 502/503 vapp includes bundled vmware tools, but to add more cpu than 8 requires hardware platform 8.So its not possible to change this hardware version on a vapp. Is that correct?

well, yes and no

there is no officially tested/supported/recommended way to do this for the vc_ops product.

but "in general", hardware versions can be upgraded if you are running the VMs on a recent version of ESX which supports it

take a look at this KB for reference VMware KB: Upgrading a virtual machine to the latest hardware version

and you have to update vmware_tools manually after that.

in addition, vcops internal configs are pre-tuned and extensively tested with the recommended amount of mem/cpu/storage, based on the size of env.
throwing a bunch of additional vCPUs on it might, or might not, improve the performance of the system.

Thanks gradinka. Need more cpu to help overcome high metric count so that DTs can complete in less time. Currently taking 4-5 days.

Does vcops "require" daily DTs or can it work the same by tuning DTs to run every week instead?

it is not required per-se... it is set so by default so that always the latest data is taken into account.

if you have lot's of data, most likely it is disk I/O which is your bottleneck, and not CPU. Even though cpu usage is 100% on the analytics_vm.
So it's worth looking into that as well.
