Typically this is one I never noticed until installing in production, the drive space requirements of the best practice analyser is quite significant see below:

  • A Warning will occur if any drive on the SharePoint server has less than 5x the total physical memory in free space, so that’s 40GB for a ‘recommended’ 8GB server.
  • A Critical alert will occur if the drive space of any drive on the server falls below 2x the total physical memory, so 16GB for a recommended spec server.

So the second one is fair, I get scared when the drive space in any server drops below 15GB or so, but the 5x warning is really annoying, basically with a ‘standard’ server with at least two drives (System and Apps) that’s 80GB minimum of wasted space to conform to the best practices. Ouch, sorry mister SAN admin!
