Short answer, No, you don't want to do that.
Long answer:
There are two types of ports on the UCS 6100, "Uplink" ports, and
"Server" ports. At this time, only the 2104 FEX modules inside the
blade chassis can be connected to "Server" ports.
The default and preferred mode of the 6100 is "End Host" mode. In this
mode, there is no MAC learning on ports configured as "Uplinks".
You could potentially change the UCS 6100 mode to "Switch Mode" and
connect your "backup server" to an "Uplink" port. However, "Switch
Mode" is not the preffered mode of operation. There are some key
benefits to "End Host" mode, such as: no STP processing, all uplinks
forwarding on all VLANs, smaller MAC tables, the simplicity of
connecting to the network like a "Host", not like a "Switch", etc.
Probably not worth the trade-off and best to connect your "backup
server" to another switch outside of the system.
Check with your Cisco UCS specialist about things coming in the
roadmap that might provide more options. Or unicast me offline ;)

We're deploying a UCS setup that involves
some of the 20 port fabric interconnect
switches which basically connect our UCS
blade chassis to our EMC storage. I asked
the sales rep today if we could plug a backup
server at 10gig into one of the unused ports
on one of the 6120's and she initially said
no, but then when I questioned what the difference
was between a backup server and our core L3
switch or the EMC storage since all are just
remote nodes talking IP on ethernet, she said
well maybe I can connect a host to it.
Trying to get some planning out of the way
and haven't gotten an answer yet so I was
wondering if anyone knows the answer to this?
Assuming the 6120XP receives a tagged
uplink from the core for normal network
traffic coming and going from the UCS
servers, can a port on a 6100 be configured
for untagged 10gig in a specific vlan so I
can hook a server into it?
Thanks,
David
