Dell's latest PowerEdge server may not look like much, but the Dell PowerEdge C6145, which began shipping on Mar. 1, gives new meaning to high-density computing. Inside this 2U chassis is the capacity for 96 AMD Opteron processor cores, 1 TB of 1333-MHz DDR3 memory, 24 hot-swappable 2.5-inches (or 12 3.5-inch) SATA, SAS or solid state drives, six half-length PCIe x16 expansion cards and a pair of x16 mezzanine slots. These are divided evenly across two fully self-contained and redundant server nodes, each of which slides out for upgrades and service.
