Dell PowerEdge R HS5620
The Dell PowerEdge HS5620 is a 2U dual-socket cloud-optimized rack server designed for telecom operators, regional cloud service providers, and large-scale software-defined storage deployments. Powered by dual 4th or 5th Gen Intel Xeon Scalable processors with 16 DDR5 DIMM slots, the HS5620 balances processing density and storage capacity across up to 8 3.5-inch or 16 2.5-inch drive bays. It eliminates excess enterprise options to deliver optimized procurement pricing and power consumption. When acquiring used units, buyers should confirm drive backplane cabling and verify iDRAC remote management connectivity.

Works together
How the Dell PowerEdge R HS5620 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.
