Possible MPU Server Purchases, 2014 - 2017

Back to MPUServerBuying2013to16

Assumptions:
  • 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
