Possible MPU Server Purchases, 2020-23

Back to MPUServerBuying2019to22.

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.
This year's additions:
  • Machines without a user login of some form can be kept going even when Intel has dropped support for their CPUs. With user logins, not so much.
  • Dell hardware is pretty reliable up to 7 years old - until that point we can just keep extending their warranties.
