I didn't say it was hard - just impractical. ;) I thought the same thing when HP told me the nodes weren't hot-swappable. But then when I learned the SuperMicros were hot swappable, I figured if SuperMicro can do it, why not HP? I'm sure you'll agree that taking just one node down instead of 4 is more convenient, and is less likely to draw the ire of your number-crunchers. -- Prentice _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
