I had a very unpleasant experience with an SMC switch awhile back. I was having problems trying to bootstrap a rocks cluster. Turns out the SMC (and Dell relabel) was so evil that it warranted a mention in the Rocks FAQ. I believe the solution was to manually turn on edge node routing or similar on each port. Unfortunately there was a bug and you could only turn on the first 16 ports. There was a fix with new firmware, but there were 2 firmware images and you couldn't tell which from looking at the switch. Said firmware upgrade caused other problems. Eventually it worked well enough. I've used quite a variety of switches without problem, I was shocked that a default switch config wouldn't work with DHCP and PXEboot. > > I'm grateful if you could weigh in with your expertise. > > Thank you, > - Art. > > > _______________________________________________ > Beowulf mailing list, [email protected] sponsored by Penguin Computing > To change your subscription (digest mode or unsubscribe) visit > http://www.beowulf.org/mailman/listinfo/beowulf _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
