40Gbps QSFP -> 10Gbps SFP+ 4way splitter

Hi

We're looking at replacing our 4 server switches. Our servers are equipped with 10Gbps NICs and so I'm looking at 10Gbps switches. These switches will trunk using fiber to our core switch which runs at 10Gbps.

I'm finding it difficult to get a definitive answer on whether all 4 of the 10G SFP+ ends of the splitter cable have to be connected to the core switch?

I'm currently looking at the HP 5940 switch in case that's relevant.

The reason for asking is that one of our sites core switch is a 24 port and free port availability is limited.
