 I would suggest if you're doing a crossover between systems, you use
 infiniband rather than ethernet.  You can eBay a 40Gb IB card for under
 $300.  Quite frankly the performance issues should become almost a non-
 factor at that point.

I like that idea too - but I thought IB couldn't do crossover.  I thought a 
switch is required?

Crossover should be fine as long as you have a subnet manager on one of the
hosts.  Now you're going to ask me where you can get a subnet manager for
illumos/solaris/whatever, and I'm going to have to plead the fifth because
I haven't looked into it.

[zfs-discuss] reminder: ZFS day next Tuesday

2012-09-27 Thread Richard Elling
If you've been hiding under a rock, not checking your email, then you might
not have heard about the Next Big Whopper Event for ZFS Fans: ZFS Day!
The agenda is now set and the teams are preparing to descend towards San 
Francisco's Moscone Center vortex for a full day of ZFS. I'd love to see y'all 
there in person, but if you can't make it, be sure to register for the streaming
video feeds. Details at:
www.zfsday.com

Be sure to prep your ZFS war stories for the beer bash afterwards -- thanks
Delphix!
