---+ 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. ---++ MPU physical servers in summer 2016 | *Service Function* | *Machine Age* | *Machine Name* | *Model* | | ==OpenAFS build server== | 9 | _budapest_ | Dell 1950 | | ==Staff SSH== | 7 | _brendel_ | Dell R200 | | ==Student SSH== | 7 | _schiff_ | Dell R200 | | ==KVM host (test/develop)== | 7 | _circle_ | Dell R710 | | ==KVM host (hot spare)== | 7 | _metropolitan_ | Dell R710 | | ==Staff remote desktop== | 7 | _northern_ | Dell R710 | | ==Student remote desktop== | 7 | _piccadilly_ | Dell R710 | | ==Spare== | 6 | _sauce_ | HP DL180 G6 | | ==SAN storage== | 6 | | IBM storage array | | ==Package mirrors== | 5 | _juice_ | HP DL180 G6 | | ==(Will soon be) spare== | 4 | _jubilee_ | Dell R720 | | ==(Will soon be) spare== | 4 | _hammersmith_ | Dell R720 | | ==Package cache 1== | 4 | _hare_ | Dell R210 II | | ==Package cache 2== | 4 | _wildcat_ | Dell R210 II | | ==KVM host AT== | 3 | _waterloo_ | Dell R720 | | ==KVM host IF 3== | 3 | _oyster_ | Dell R720 | | ==Offsite KVM host 1== | 2 | _amarela_ | Dell R720 | | ==Offsite KVM host 2== | 2 | _vermelha_ | Dell R720 | | ==RPM/package master== | 2 | _bruegel_ | Dell R210 II | | ==LCFG master== | 2 | _steen_ | Dell R210 II | | ==Offsite disaster recovery== | 1 | _salamanca_ | Dell R320 | | ==KVM host IF 4== | 1 | _azul_ | Dell R730 | | ==KVM host IF 1== | 0 | _gaivota_ | Dell R730 | | ==KVM host IF 2== | 0 | _girassol_ | Dell R730 | ---++++ 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. * _northern_ and _piccadilly_ are powered off and kept for spares. * ==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 -
