On one of the C6145's two identical motherboards we see its four-processor heat sinks surrounded by its 32 RDIMM/UDIMM slots, each of which can handle up to 16 GB, for a grand total of 512 GB per server. Along the left side are the slot risers for low-profile PCIe expansion cards. The cramped quarters allows for two x16 cards of 6.667 inches in length, and a third at 4.795 inches, according to Dell's documentation.
Still, we would have preferred to see more than just two built-in networking interfaces per server, particularly for a machine that's intended for virtualization. The CRN Test Center recommends the Dell PowerEdge C6145 for any installation in need of a high-density, high-performance server with plenty of redundancy features. The C6145 as tested here carries a list price of $19,502. For more information about CRN's experience with the PowerEdge, please read the full review.
