The C6145 is actually two, 4-socket servers in one, with each sled sliding out rearward for upgrades and maintenance. A top cover slides backward slightly and lifts out to reveal processors, fans, memory and its three half-length PCIe x16 expansion slots (shown here and in a later slide).
For tests, we configured each node as a stand-alone server running 64-bit Windows Server 2008 R2. Each server was populated with four AMD 6132HE 12-core processors, and each with its own 128 GB of memory. However, Windows addressed only it maximum of 32 GB. The peak score of 22,607 was observed when running the 64-bit version of Geekbench on node 2. Node 1's high water mark was 21,257. The PowerEdge C6145 is aimed squarely at HPC applications, virtualization, VDI and EDA workloads. We'd say it's well qualified.
