Possible MPU Server Purchases, 2019-22

Back to MPUServerBuying2018to21.

Last year's assumptions:
  • We can use virtual machines for non-critical "slave" roles.
  • Where we can replace server hardware with VMs we should do so, to release the server hardware for use elsewhere.
  • The LCFG master should be relatively young as it is so critically important.
  • The VM servers should be relatively young.
  • Servers are now purchased with a 5 year warranty.
  • We don't care how old ssh servers are because they can be any old server (within reason). We'd prefer not to virtualise them.
  • Any hardware fulfilling a non-critical function can be left until it fails, then replaced.
