The Servers
We use mainly Supermicro Servers for our server builds.
Each server is connected to our network with at least two gigabit intefaces, one for the WAN, one for the LAN.
We only use enterprise components for our server builds, every server has out of band management (IPMI)
We also have control of the power distribution to each server trough our APC Masterswitches.
These can be customised to your requirements, any build is possible.
