Do you know is this will work in either a Dell PowerEdge 2950 (9th Gen) or PowerEdge 2650 (6th gen) server?

Thank you for your question . It could work if your server has PCI-E X8 X16 slot , and supports the operating system that Broadcom BCM57810S NIC compatible. You are welcome to have one to test.

If you insert an SFP+ module that supports both 10g and 2.5g, and connect to a remote 2.5g switch port, will it work?

No, the 10G SFP+ network card does not support 2.5G rate.

Does this card work with the cisco sfp+ ??

It has worked with every sfp+ cable we have thrown at it, probably a total of 5 various cables coded for different manufacturers. I will say though, we have not specifically tested with Cisco.

Does this card work with server 2016 and esxi 6.7?

Yes, HiFiber's 10Gb NIC card for Broadcom BCM57810S could work with server 2016 and esxi 6.7.
