Server Network Adapter

The Dell Chelsio T6625M-CR is a genuine OEM dual-port 25G SFP28 network card built for Dell PowerEdge servers including the R640, R740, R750 and R940. It installs into a PCI Express 3.0 x8 slot to provide enterprise-grade connectivity for data centre and cloud workloads. This new replacement part suits administrators upgrading or repairing compatible Dell server platforms.

Offload And Virtualisation Support

The Chelsio T6 controller enables RDMA, iSCSI and TCP/IP offload functions that reduce host CPU overhead during intensive network operations. Compatibility with VMware, Hyper-V and KVM platforms means the adapter integrates directly into existing virtualisation clusters. SFP28 ports accept both optical transceivers and direct-attach cables for flexible link choices.

Throughput And Latency Headroom

Dual 25GbE ports deliver high bandwidth for storage replication, cloud traffic and virtualised workloads while maintaining ultra-low latency. The PCIe 3.0 x8 interface provides sufficient bus headroom for sustained line-rate performance on both ports simultaneously. Environments requiring higher port density or speeds beyond 25GbE will need additional or different adapters.

Questions about this item

Will the SFP28 transceivers on the T6625M-CR need periodic replacement?

The dual-port card uses standard SFP28 modules for 25GbE links; only the transceivers themselves may need swapping if a link fails or you change media type.

What limits sustained throughput on the Dell Chelsio T6625M-CR?

The PCI Express 3.0 x8 interface caps total bandwidth, so both 25G ports combined cannot exceed that bus ceiling under continuous load.

How much heat and power does the C9GKH adapter produce when running all day?

The energy-efficient PCIe 3.0 x8 design keeps power draw and thermal output low, allowing standard server airflow to cool the card without extra fans.
