Not sure if this helps but I had a similar problem.
The problem ended up being the start up time for a port on the switch.
We disabled STP and the startup delay on the switch.

I don't have experience with that particular server type, but we also
have (Quanta and Dalco/Intel) servers with GigE and 10GE interfaces. We
never use the GigE (except the separate BMC/IPMI port) and always
PXEboot from the 10GEs. So it should be possible (unless IBM did
something nasty).
It works fine with the 1GBs nics but not with the 10Gbs. I enabled
debugging on the tftp server but it looks like the server is not even
reaching it. During boot I can see that both NICS register with DHCP
and that's it.
I wonder if it is a setting on the 10GBs switch like DHCP helper adress?
If your 10GE ports are on the same logical subnet (VLAN) as the GigE
ports, then that shouldn't be necessary.
What we do is that we put the (untagged/default VLAN) 10GE ports in a
special "provisioning" network that the DHCP server controlled by
Foreman (Smart Proxy) has access to. So we don't need DHCP helper
addresses.
(Once the systems are installed, they will not use that VLAN anymore.
They use separate VLANs that are used for production traffic.)
Another possible reason for your problem may be that the system doesn't
try to PXEboot from the 10GE ports. That's something that you can see
by staring at the console while it's trying to boot, and/or by running
tcpdump looking for packets from the 10GE interfaces (you can filter by
their MAC addresses; of course you must run the tcpdump on a port that
"sees" all traffic from those servers' 10GE ports). If the server
doesn't want to boot from the 10GEs, then *maybe* you can fix it by
changing BIOS settings. But depending on the age of the server/BIOS, it
may even turn out that PXE isn't even supported on the 10GE ports.
Hope this helps,
