---+ Possible MPU Server Purchases, 2016-19

Back to MPUServerBuying2015to18. See also DisplacedServers2015.

---+++++ 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.

---++++ 2016-17 Developments:
(Each fresh indentation indicates a dependency on the previous event.)
   * New servers _gaivota_ and _girassol_
      * ==KVM host IF 1== and ==KVM host IF 2== move to _gaivota_ and _girassol_
         * _jubilee_ and _hammersmith_ are free.
            * ==Student remote desktop== and ==Staff remote desktop== move to _jubilee_ and _hammersmith_
               * _northern_ and _piccadilly_ are free.

   * ==OpenAFS build server== moves to _sauce_.
      * _budapest_ is free.
         * All of Informatics' 1950s have now been disposed of, so we get rid of _budapest_.
   * _oyster_ moves to Appleton Tower to become ==KVM host AT 2==, freeing up _circle_ from its subsidiary duty as backup to _waterloo_.
   * (*High priority purchase*) Two new servers _een_ and _twee_ with desktop style CPUs - guesstimate cost £1000 per server
      * ==LCFG slave 1== and ==LCFG slave 2== move from VMs to _een_ and _twee_
   * (*Lower priority purchase*) New server _drie_ with enough storage to provide several TB of usable space in RAID 10. - guesstimate cost £2500
      * ==Packages mirrors== and ==RPM/package master== merge and move to _drie_.
         * _bruegel_ and _juice_ are free.
            * ==Student SSH== moves to _bruegel_.
               * _schiff_ is free.
