Dell PowerEdge R740xd2
The Dell PowerEdge R740xd2 is an enterprise storage server that revolutionized 2U capacity by packing up to 26 3.5-inch hard drives into a standard rack chassis using dual front slide-out drive drawers. Designed for video surveillance recording, massive content archives, big data analytics, and cloud tiering, it provides over 500TB of raw capacity in just 2U. Powered by dual 1st or 2nd Gen Intel Xeon Scalable processors with 16 DDR4 DIMMs, it balances compute and massive bulk storage. Buyers on the refurbished market should inspect drawer cable management arms and test drive drawer latches.

Works together
How the Dell PowerEdge R740xd2 connects to servers, storage and the network: 4 ways, with the parts and products on each path.
Fibre Channel SAN
Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).

Optics
iSCSI and NVMe/TCP over Ethernet
Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Direct-attached SAS
12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.

File storage (NFS and SMB)
Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.
