Mark,
While I don't have any experience with UCS blades (as of yet), however, I have recently participated in a call with the Cisco team that implemented a three-node HP Superdome to 12-node UCS blade migration of their 40 TB Oracle ERP system. One of the things mentioned on the call was the noticeable different in the interconnect speed between the HP and the UCS platforms where the latter had a much lower latency and almost to a point where the workload partitioning was not even necessary. I know this is not what you are asking but I wanted to pass on the information to you.

Subject: High ping times on interconnect for Cisco UCS servers....
Hi,
Does anyone have any experience with Cisco UCS servers?
I've just been handed my first batch of them, and I'm getting ready to install a two-node RAC. These servers are replacement for HP DL360s. I currently have a two-node RAC running on the DL360s. The ping times on this RAC, with bonded 1GigE NICs, are around 0.070 ms. On the new UCS servers (10GigE "vNICs"), my ping times are in the neighborhood of 0.170. That's about 2.4 times slower...
I fully expected *faster* ping times for 10GigE interface....
So, has anyone seen something like this before? Any thoughts? Ideas?
FYI, I also have a second two-node UCS server RAC that I'm getting ready to set up, and it seems to have the same problem.
Any ideas, thoughts, or suggestions, would be appreciated.
Thanks,
-Mark
