A client of ours has a system in place and they are currently sitting at about 75% cache usage.
We use Veeam to replicate (daily) to a datacentre for backups and DR so don't use the snapshot feature.
They have a number of servers that are static in nature and with them being backend servers, they are only read from occasionally by internal services.
My question is, is it worth moving these to a non cached volume so the caching can be used more for the always accessed data as I assume the reading of these servers daily is putting data into cache. Could we use the cache in a better way for the more prominent production servers? Or does the figure of 75% represent that this isn't an issue and data being read is cached.
