[osuosl-openpower] Hypervisor server moves next week

[Lance Albertson]

All,

We need to do some emergency server moves next week starting on Tuesday.
This is to help balance the power and cooling in the datacenter where these
systems are located. Most of these moves can be done with little to no
downtime for users, however there will be some users that will notice
longer downtimes.

The biggest impact will be any users on any of the two NVMe (local storage)
hypervisors. We are planning on moving those two systems on Tuesday, July
5th between 2-5pm PDT.

Provided we have enough RAM available on all of the systems, we should be
able to migrate most other users to unaffected systems as we make these
changes. If not, we may end up shutting down the systems (and the VMs
hosted on them) while we move the system as quickly as possible.

There is always a possibility that something could go wrong so expect
outages next week just in case. We'll be moving power distribution units,
cables and so forth and we may accidentally pull the wrong cable. We always
try but sometimes things happen.

We will be doing these moves during the workday (PDT) throughout the week.
I will try to send updates in case there are any unexpected outages if they
happen.

Thanks for your patience and support!
