Possible MPU Server Purchases, 2015-18

Back to MPUServerBuying2014to17. See also DisplacedServers2015.

Assumptions:
Some have been added or deleted compared to last year's.
  • Machines in service should not be more than six years old.
  • 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 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
  • Any hardware fulfilling a non-critical function can be left until it fails, then replaced.
