We have been running out of disk recently with some indexes requiring more than 400GB of space per index replica. Actual disk space requirements are double that as we run with a replica. On top of that the idea is that 5 of 6 elasticsearch nodes have enough space for all our data so that we are resilient to losing a node. Napkin math: 400 * 10 * 2 = ~8TB of disk 400 * 7 * 2 = ~5.6TB of disk Each of the six ES nodes has 1TB of disk allocated to ES so 5.6TB should get us just under the limit. Then for handling a node outage weekends tend to not have as many records so our actual usage should be a little lower. Change-Id: Ie677bd47a9886870bc83876d2407742133299861
