3 Jim Magallanes Small IT Rooms  Data Centers & Large Computer Rooms Always include a dedicated cooling system  Small IT Rooms Many IT devices are located outside computer room  Closets /Branch Offices / Storage Rooms / Open Offices  Never designed for cooling IT equipment Power density of IT equipment has increased over time  Servers / Telecom / VOIP Routers & Switches / UPS Floor Space is a Premium: <100 ft 2 Contents: 1 – 3 Equipment Racks Heat Load per Rack: kW Avg. Typical Cooling: None or Building Cooling During Day Remote location of building Security: Medium  Locked Door and/or Locked Cabinet “The average wiring closet contains $150,000 - $300,000 of equipment and a typical small server room often houses more than three times that amount.” - Mitch Medford, NetBotz CTO Cooling Strategies for Small IT Rooms – CTM 2013 Operations Seminar

4 Jim Magallanes Small IT Rooms  Approach to cooling small IT Rooms Ignore cooling requirement Deploy equipment … deploy more equipment Call CTM frantically when IT equipment overheats and/or fails  Average small IT room can contain up to several hundred thousand dollars of equipment  Network down results in more than IT replacement cost  Lost sales / productivity / equipment / data  Cooling Strategy Requires proactive approach ensuring the uptime availability of your IT network  Cooling Strategies for Small IT Rooms Basic cooling principals for small IT rooms Available cooling options Cooling Strategies for Small IT Rooms – CTM 2013 Operations Seminar
