p.p.s:
Is this going to be SAN attached or not?
If EMC and you plan on using PowerPath, then only go for SP2, as SP3  
of SLES9 is not yet certified for PP.

If standalone, then get U3 as it will save you the hassle of driver  
disks for your "exotic" array controllers.
The kernel drivers will likely not see any of your LUNs during  
installation, suck em and see.
