We have the dell-equivalent (PERC 5/e and PERC 5/i) in production and
have had no issues with it, it also performes very well (compared to a
ICP Vortex controller). The LSI has been benchmarked by my colleague and
he was pleased with the controller.

We have 15 of the 36GB drives and they are doing great. According to
that same colleague, the Fujitsu drives are currently the best
performing drives. Although he hasn't had his hands on the new Savvio
15k rpm drives yet.

You could also look at this version of that chassis:

Afaik it sports a 28-port expander, which should (please confirm with
your vendor) allow you to connect all 16 drives to the 8-ports of your
controller. Which in turn allows your both sets of disks to be used with
your BBU-backed controller.
