All, We have 3 ES servers and we would like to store the ES data files in a SAN instead of local storage .We can have 3 differnt LUNs presented to these 3 differnt severs.

Please let us know if this work or there is a better way of doing this.

Is the SAN fast?

Given Elasticsearch is used to responding in the same amount of time, that might cause delays. But you'd need to test it.
