4820C Converged Network Adapter (CNA) Speed

[IncidentalAdmin]

Hello,

I'm new to the Synergy line and have a very basic hardware question.

At what speed does the 4820C CNA operate, and under what circumstance?

I am currently assuming that it works at:

• 10GB in converged (i.e., FC + ethernet)
• 20GB in ethernet only mod when using 40GB Virtual Connect. 
• 25GB in ethernet only mode when a Virtual Connect SE 100GB F32 i installed in the interconnect bay.

  Can someone confirm this is correct?

The answer came from another member, whom I have thanked.

"- The speed at which the CNA connects to the VC (Virtual Connect) interconnect, id determined by the speed of the ILT.
- If you have a 10Gb ILT then the CNA connects at 10Gb and if you have a 20Gb ILT it connects at that speed.
- If this CNA is linked with a VC 100Gb then it will connect either at 25Gb or 50Gb depending on the ILT speed.
