be aware that intel based 2.5gbps nics are only 1 port. If you need a 2 port 2.5 nic, it will be a Realtek.  Realtek in a lot of cases needs you to install additional drivers so wont necessarily be plug and play. also there are 2 port 2.5g intel nics, but the chipset only supports 2.5gbps total throughput, so those cards only have 1.25gbps per port depending on how they have it built. so not 'true' dual port 2.5gbps like the realtek ones.
Hello, I have an old DELL T310 that is working perfectly for my needs. I need to install a 2,5gbps network card or 10gbps, to reach the maximum speed of the 2,5gbps internet fiber connection. The dell t310 pci bus speed can reach at least 2,5gbps? I have already installed a SAS Pci card with 6 HD...it's the pci bus speed shared? I can install any cheap 2,5gbps network card? Really thank you. Regards.
10gbps / 2,5Gbps PCIe card for DELL T310?
