Not knowing any of your requirements, I'll say what works well for us. We use cabinets with built-in casters that are 42U high and 24 in. wide. The 24 in. width nicely accommodates our 19 in. wide servers and indexes well with our 24 in. raised floor panels. Higher than 42U racks bump into many overhead obstacles. We end up using the bottom few spaces for cable entry and UPS and the top of the rack for patch panels and rack switches, so we plan for a maximum of 75% rack fill.

We use racks with square hole rails, which accommodate most modern equipment mounting rails, and use cage nuts in case something needs to be mounted with screws. We try to limit rack weight to 2,000 lbs. to stay within the limits of the raised floor specs.

We prefer racks made by companies who do not manufacture servers and find APC's AR3300 racks to offer excellent value. Other very good brands recommended in other threads include Rittal, Emerson and Chatsworth.

Hope that helps.


Ken
