Only the larger switches were from QLogic (144 and 288 ports) all
other switches were made by TopSpin/Cisco directly. Cisco is not
leaving the HPC space only IB.
Btw: you can still buy cables from Cisco. But as mentioned, all
cables come from 3rd party vendors.

I'm sure you're right. It's my understanding that IB is a

others and refuse support if we're not using all Cisco kit.
Then buy from an IB vendor that isn't silly like that. QLogic and
Voltaire are choices. Is Cisco still re-selling QLogic switches?

Again,
they aren't the only IB provider out there (seems such a shame,
gobbling
up TopSpin and then effectively discarding them).
Apparently the main attraction of TopSpin was their virtualization
software. Cisco, of course, supports all the major technologies, so it
can be hard to tell if they really are transitioning to something
else. At a minimum Cisco will want to sell gateways for all
non-Ethernet technologies. After TopSpin was bought, Cisco continued
to sell gateways developed by TopSpin, but sold rebranded QLogic DDR
switches.
