hrm. i thought i had heard of someone using drbd over 10 gig with netxen cards. i went looking for a few minutes and didn't find anything though. my recommendation would be try newer drivers either through compiling the drivers for you existing kernel or using a newer kernel. i don't have details on how to do that for your cards cause i have never used any 10 gig from hp or netxen. other than that, my only recommendation is new nics. good luck mike James Larcombe wrote: > > Hi Mike, > > > > The cards I'm using are HP NC522SFP Dual Port 10GbE Server Adapters > with HP BLc 10Gb SR SFP+ Fiber Transceivers.
