Hi,
I have two of the 6200 fabric interconnects, and I need to connect to a port of the HP 5900 QSPF+ ports, I was thinking of getting one of these cables that QSFP that splits into 4 x 10GB cables.
The HP switch is a full 10GB ethernet switch with 2 x QSFP ports, however Cisco do not look to sell any SPF modules that are Ethernet presentation. So I'm left with the QSFP modules instead.
However I know the UCS is fussy about the transceivers, so I was wondering what is the best QSFP cable to purchase. Because previously when connecting a UCS FI to a HP Switch using 10GB modules, I've had to buy Cisco modules for the UCS FI and HP Modules for the HP Switch.

The 6200's don't have 40G ports so they don't support QSFP's.
The 3rd Gen FI's the 6300's would be able to do this.

Greetings.
If I understand your question correctly, you are concerned about the interop of the 10Gb transceivers at the end of a QSFP breakout cable that connects to the 6200 FI. I could not find any data on that either, as the 6200 datasheet is only going to list supported Cisco PIDs. If you can get one of the 3 or 4 listed HP QSFPs to 10Gb breakout cables to work, you may still have supportability questions if you start running into odd L1/L2 type issues.
You may want to try using the native 10Gb ports on the HP so you can use some known compatible SFP+ transcievers on the UCS 6200 side if you run into issues with the HP breakout cables.
Like Majid mentioned, the Gen 3, 6300's will have more options for native QSFP connectivity.
Thanks,
Kirk
