The current cluster has 4 nodes with 48 TB of raw capacity, which is 65% utilized. This means that the cluster has 28.8 TB of free space.To upgrade to 2048 x 1536 resolution with a 30 days retention policy, the cluster will need to store 4 times as much data as before. This means that the cluster will need 115.2 TB of raw capacity.To achieve this, the cluster will need to add 10 nodes of the same type. This will give the cluster a total of 14 nodes with 144 TB of raw capacity, which is 70% utilized.
