Possible MPU Server Purchases, 2018-21
Back to
MPUServerBuying2016to19.
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.
