not just ubuntu...the dell perc/x line software  utilities also
explicitly check the hardware platform so they only run on dell
hardware.  However, the lsi logic command line utilities run just
fine.  As for ubuntu sas support, ubuntu suports the mpt fusion/sas
line directly through the kernel.

In fact, installing ubuntu server fixed an unrelated issue relating to
a qlogic fibre hba that was causing reboots under heavy load with a
pci-x fibre controller on centos.  So, based on this and other
experiences, i'm starting to be more partial to linux distributions
with faster moving kernels, mainly because i trust the kernel drivers
more than the vendor provided drivers.  The in place distribution
upgrade is also very nice.
