Say I have 12 VM servers on 3 hosts. They all perform different function like decryption, zip/unzip, etc on large "input" files. To avoid moving these files from one server to another I put them on a file share that all these servers can access, now what used to take 30-40 mins is taking 5-6 hours.
What are my options? someone suggested "Shared LUN" but after reading about that it looks like its frowned upon by the storage experts because exposing a LUN to multiple servers without some coordination leads to your volume going sideways.
