The Dell PowerEdge R420 features the extensive performance of two Intel E5-2400 processors. Powerful processors alone, however, are not enough to deliver balanced performance. Compute power must be combined with sufficient memory and I/O bandwidth to prevent performance bottlenecking. The Dell PowerEdge R420 complements its processors with 12 DIMM slots and two PCI Express (PCIe) 3.0-enabled I/O slots, providing a substantial memory footprint and wide I/O bandwidth to support both memory-intensive and data-intensive applications and databases
