The Dell Power Edge R420 is a 2-socket, 1U rack-mount server offering an aggressive entry-price point combined with internal expandability, enabling configurations to be tailored to specific workloads & user requirements, & supporting growth through the life of the server. The R420 is an excellent fit specializing in departmental email, workgroup collaboration, web hosting, e-commerce & file & print in space-constrained environments & in departmental or remote sites of large businesses & public organizations. The R420 is also highly attractive for compute-intense applications in space-constrained areas, as well as high-performance computing (HPC) workloads. Consistent worldwide support makes it appealing to multinational businesses & organizations. The R420 features the extensive performance of two Intel Xeon processors. Powerful processors alone, however, are not enough to deliver balanced performance. Compute power must be combined with sufficient memory & I/O bandwidth to prevent performance bottlenecking. The R420 complements its processors with 12 DIMMs & two PCI Express (PCIe) 3.0-enabled expansion slots, providing a substantial memory footprint & wide I/O bandwidth to support both memory-intensive & data-intensive applications & databases. These combined technology features are also necessary to support consolidated & virtualized environments, a role the R420 fills well. To protect your virtualized workloads, the R420 offers dual SD media making your hypervisors redundant & failsafe.
