Change Details

As part of {T342750} we will be deploying a new ceph cluster in the codfw datacenter. Before implementation, we may want to decide on some details, like initial minimum capacity, rack distribution, etc.

Before implementation, we may want to decide on some details, like initial minimum capacity, rack distribution, etc. As a first approach, we might want to start with 8 ceph nodes, spread in 4 racks for high availability (we have 3 replicas). Any less nodes and the high availability gets compromised and we risk the cluster halting if a rack goes down (and with one node per rack, a single node going down makes the rack go down xd).
