?George,
yes the elephant as a 1U. Orangutan is 2U.
Are those new systems (future bears) IPMI capable ?
What is hurting us, on the rack, are our power switches as we don't have Big
capacity UPSes.
What we have here are upses with around 900 W load capacity which is not
enough to support 8 devices on boot up or when they are under extreme load.
