  • Silicon Mechanics (siliconmechanics.com) - Seattle area, used extensively by CSL/Gates
  • Mazda Technologies (packs X58 chipset-based, core i7s in 1U machines)
  • Penguin Computing (usually more expensive)

Power

  • We will have two 220v three 250v plugs (probably 30A each) Need to get the NEMA code (C15, L630?!)20A each - L6-20R is the socket)
    • Should probably get 4 PDUs for 20kW total. Can likely scrounge a fourth socket if we need it.
  • PDUs commonly come with 24 plugs, so we'll likely want two, one for each 220v source.
  • Twin servers share a power supply, so we cut down on the number of plugs that way.
    • Quad servers apparently share 2 power supplies, but need only one to run (i.e. redundant power by default).
  • PDUs run ~$750 for 24 plugs
  • Was some concern that the Infiniband and 10GigE switches could be very power hungry
    • Our Mellanox 36-port switches are IS5024 (XXX verify):  ?? watts
    • Arista 24-port switch (7124S): 210W "typical power draw"
