The Dell PowerEdge T550 is a flexible 5U tower-to-rack convertible dual-socket server driven by 3rd Generation Intel Xeon Scalable (Ice Lake) processors. Built for corporate edge virtualization, database management, and remote office infrastructure, it provides 16 DDR4 DIMM slots for up to 1TB of memory and up to 24 2.5-inch hot-swap drive bays (including up to 8 NVMe drives). The T550 is engineered for quiet office acoustics while maintaining full PCIe Gen4 expansion and iDRAC9 remote manageability. When shopping on the secondary market, ensure the internal cooling shroud and heatsinks are intact.

Works together

How the Dell PowerEdge T550 connects to servers, storage and the network: 4 ways, with the parts and products on each path.

Fibre Channel SANiSCSI and NVMe/TCP over EthernetDirect-attached SASFile storage (NFS and SMB)

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).

Fibre Channel SAN: how it fits together

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.

iSCSI and NVMe/TCP over Ethernet: how it fits together

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.

Storage

Direct-attached SAS: how it fits together

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.

Buying a used T550: what to check

Check CPU socket load plates and verify cooling fan shrouds are undamaged. Confirm whether tower stabilizer feet or 5U rack rails are provided.
