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.
