Dell Servers with Nexus 7000 + Nexus 2000 extenders

<< Original post by smunzani. Answered by Robert. Moving from Document section to Discussions>>


I would like to use some of the existing Dell Servers for new network design of Nexus 7000 + Nexus 2000 extenders. What are my options for FEC to the hosts? All references of M81KR I found on CCO are related to UCS product only.

What's best option for following setup?

N7K(Aggregation Layer) -- N2K(Extenders) -- Dell servers

Need 10G to the servers due to dense population of the VMs. The customer is not up for dumping recently purchased dell boxes in favor of UCS. Customer VMware license is Enterprise Edition.

Thanks in advance.

To answer your question, the M81KR-VIC is a Mezz card for UCS blades only.  For Cisco rack there is a PCIe version which is called the P81.  These are both made for Cisco servers only due to the integration with server management and virtual interface functionality.
