interesting, i wonder if you could answer a few questions about the lsi card:

1. how do you manage the array(s)?  bios (before the OS boots)?  within the 
OS (with some kind of utility)?

2. did you have to compile/install any kernel modules or drivers, or are 
they in the stock kernel?

3. any provisions for monitoring the array status and/or alerting you if a 
problem is discovered?

thanks - jason
