I've disccused this small fix to EquinixMetal with my friends at Equinix and they are supportive.

lgtm.

The specs in the general plan list only use GB today:

$ metal plans list -o json | jq -r '.[]|.specs.memory.total' | sort -n -u
null
16GB
32GB
64GB
128GB
192GB
256GB
384GB
512GB
768GB
1024GB

There are workload-optimized and custom reserved hardware instances that may have the memory spec written as this PR would address. This is a reasonable defensive patch.

I verified that this raw python block handles the input.

@luss do you have instances that return the memory in this format today?

@luss It seems we now have 3 Equinix Metal PRs up:

• EquinixMetal small fix to handle large instances RAM measured in TB #1970
• chore: Deprecate facility in the favor of metro #1971
• chore: Remove storage and volume interface implementation #1972

This PR's inclusion of 50c187e is complicating this PR and tying it to the features present in the other two PRs. Can we remove that commit from this PR?

For testing purposes, if you want to run with all of the PRs, I'd suggest using a different branch for that, one that is not opened as a PR.

I'm not the worlds biggest git expert.... I will create a new PR from a clean repo that has only my suggest fix. The I will withdraw this PR
