HP POD 20c capacity limitations
The capacity limitations for the HP POD 20c are separated into two categories: electrical power and
mechanical cooling capacities. Both of these categories are interdependent and must be considered in
conjunction with the overall customer requirements.
Electrical power capacities (critical IT power)
The electrical system of the HP POD 20c contains two main feeds, A and B, that are each rated at 400 A
380-415 VAC Wye 3-Phase. The HP POD 20c has two critical IT load feeds that are each rated at 200 A,
which electrically limits the POD regardless of the redundancy configuration.
Mechanical cooling capacities
The HP POD 20c cooling system consists of 3 zones. Each zone includes 2 heat exchangers and 12 fans.
Cooling capacities are based on:
• Chilled water inlet temperature of 15.6ºC (60ºF)
• Heat exchanger fluid delta temperature of 5.5ºC (10ºF)
• Pure water cooling
• Chilled water flow rate of 454 lpm (120 gpm)
• Average air flow of 1750 cfm per rack
Overall system capacities
The HP POD 20c overall system capacities are provided in the following table. The customer must understand
the level of redundancy required for the application and its associated limiting factor.
