VCSA v7.0 Storage Use

That_VM_Guy — Fri, 24 Apr 2020 14:11:10 GMT

This is resource use from my work vCenter 6.7 server running 5 datacenters in three countries with 336 VM's.

This is from my vCenter homelab that I updated to from 6.7 to 7.0 last night running 5 small Linux vms on a single host.

Why does this require half of my 1TB datastore? Is there anything I can do to reduce this massive chunk of storage?

Here are the drive stats for the VCSA. Massive overkill.

I'm going to see what I can do to reduce this without impeding the day to day operations.

There is no supported way so shrink the partitions.

I basically agree with you. The partition sizes (or should I call it disk space reservation) are most likely massive overkill for most use cases. It's similar to ESXi 7.0 itself, where a fresh installation will use up to ~128GB on the installation disk. Anyway, most modern storage systems support thin provisioning, zero detection, and other things, so that the whole disk space is not going to be used up front. For storage system without thin provisioning options, thin provisioned virtual disks may be an option.

Hi Benedikt,

I know that. What I'd love is the ability to define my own HD sizes, mem use and CPU.

Having this much storage use on a home lab is crippling.

Thanks.

For the homelab there is always the thin provisioning
