Hey!

So by design your deployment should be fault-tolerant in case you are
using keepalived or anything like that for VIP failovers. So you
should be able to safely move blades between chassis.
The only thing to remember about, which might cause some effect - is
memcached, as it can not be set in any HA mode. What makes things
worse, is that memcached clients might be waiting for connection
timeout when connection is not refused by remote host, which might
happen during host shutdown - where it does not accept connections
anymore, but also still reachable.
You can check on more details here:
https://docs.openstack.org/openstack-ansible-memcached_server/latest/alternate-configurations.html

But in general it should be really fine.
