I have some doubts about VM-FEX, I can only take advantage of this solution with Cisco UCS servers, right? If I have servers from other vendors, the solution is the Cisco Nexus 1000V, right? I need a solution to have more control in a new VMware Cluster.
I take one more question to this community, what alternative have on the netflow cisco nexus 5500?
Thanks to all
Yes you are right.
There are two ways to do virtual networing.
1. Thru ToR switch
2. Thru Software switch inside hypervisor
Adpter FEX is Single root I/O virtualiation technology that allows you to virtualize you network interface card into multiple vNIC(128 PCIe standards-compliant virtual interfaces). These vNICs are presented to OS (such as vmware ESXi). You can assign these vNIC directly to VMs and manage these vNIC directly from ToR switch(such as Nexus 5500) these technology called VM-FEX Only works with p81E and Nexus 5500 OR UCS fabric interconenct with B series blade server and M81KR and VIC 1280. The Cisco UCS P81E is designed specifically for Cisco UCS C-Series Rack-Mount Servers and VM-FEX and Adapter FEX only supported with P81E so I do not think you can use it on any other server.
Other option is to use a software switch inside hypervisor and manage your vNIC thru it. Solution available from Cisco is Nexus 1000v, which only requires hypervisor vendor supported NIC card and does NOT require any specific Cisco server or NIC card such as P81E.
As I said there are other options(802.1Qbg) available to manage you vNIC of VMs thru ToR switch or other software switches from different Vendor.
