No, it will not, because SLES doesn't provide a very uptodate ext4  
code, and a number of 16TB fixes went into ext4 late in the game.   
RHEL5.4, on the other hand, has very uptodate ext4 code and the RHEL  
ext4 maintainer is one of the ext4 maintainers himself.

I believe a few large customers are already testing/using this.  I'll  
let them speak for themselves.

Cheers, Andreas
