Using the low water mark, and a cost per KwH (inclusive of cogen generation costs, maintenance, CP&L power imports, heat reclamation costs, etc), the total cost for both power and cooling consumption is estimated at $27,489 per year for the Dell racks. | Using the low water mark, and a cost per KwH (inclusive of cogen generation costs, maintenance, CP&L power imports, heat reclamation costs, etc), the total cost for both power and cooling consumption is estimated at $27,489 per year for the Dell racks. |

New hardware could replace the Dell's functionality and reduce power/cooling needs in the data center while yielding significant savings. An 8-node cluster with each node comprised of dual 8 core CPUs, each with 256 GB of memory and a 15K 300 GB hard disk, all nodes connected to a fast throuput/low latency switch, would match or exceed key parameters such as gigaflops of computational power and number of job slots provided (with hyperthreading enabled). | New hardware could replace the Dell's functionality and reduce power/cooling needs in the data center while yielding significant savings.

Such a cluster would consume 77% less energy generating $21,094 in saving per year (after accounting for energy needs of that 8-node cluster). This implies that in 2.9 years the cost of acquiring that 8-node cluster ($61,714) will be recouped. Based on the low water mark. | Such a cluster would consume 77% less energy generating $21,094 in saving per year (after accounting for energy needs of that 8-node cluster).
