Let’s say I have 6 nodes in my cluster, each with a disk of 1TB for cockroachdb storage, allwithing a single datacenter & availability zone, for simplicity.
My usable capacity in the dashboard will most likely be 6TB, but with a
num_replicas of 5, how much actual data will I be able to store in those 6TB?
The 6TB available throughout the cluster will also be used for replication & system data.
Is the formula
<total capacity>/num_replicas, in this case 1.2TB, a good approximation?
