The HP Performance Optimized Datacenter (POD) is a range of three modular data centers manufactured by HP. Housed in purpose-built modules of standard shipping container form-factor of either 20 feet or 40 feet in length the data centers are shipped preconfigured with racks, cabling and equipment for power and cooling. They can support technologies from HP or third parties. The claimed capacity is the equivalent of up to 10,000 square feet of typical data center capacity depending on the model. Depending on the model, they use either chilled water cooling or a combination of direct expansion air cooling.
