Dell PowerEdge T140
The Dell PowerEdge T140 is a compact, entry-level single-socket mini-tower server designed for small businesses taking their first step into dedicated on-premises IT. Powered by Intel Xeon E-2100 or E-2200 processors, it supports up to 64GB of DDR4 ECC unbuffered memory across 4 slots and holds up to four cabled 3.5-inch hard drives. Quiet and energy-efficient, the T140 is ideal for file storage, printing, point-of-sale, and accounting software in small retail or office environments. Pre-owned units are popular among homelab hobbyists. Buyers should verify that unbuffered ECC UDIMMs are installed.

Works together
How the Dell PowerEdge T140 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.
