Rack

The ATLAS Cluster is physicall hosted in two 19 inch racks; they are identical and are named Door and Wall; the former is the one closer to the entrance door while the latter is the one away from the entrance door.

Each rack houses, from top to bottom: four nodes, a Cisco Catalyst switch, three more nodes and an APC UPS; in total each rack has seven nodes.

Door rack
From top to bottom this rack houses the following nodes: mu, delta, beta, psi, iota, eta, tau.

The InfiniBand switch is also located in this rack; cables from the 6 nodes with InfiniBand which are located in the other rack connect here and this prevents the rear panel of both racks from being mounted.

Wall rack
From top to bottom this rack houses the following nodes: nu, omega, kappa, rho, pi, zeta, xi.
