How much rack space do you have? Anyway, back to V240, yes it takes 4
drives, 146GB max each if under sun support but there are ways to go
higher. You mention that performance is not critically important, but
max space is. Does it need to be redundant?
You could also add something like an ST-D130 adding 3 more drives in
1U (i know you said no external, but you might want to consider a 1U
solution).

Why hardware raid, also? What are you going to run on this? zfs zraid1
with compression is really nice on those v240. BTW, sol 10 u4 will let
you configure zraid1 including boot disk (supported by sun - you can
actually do this on x86 hardware with solaris 10 u3 or solaris nevada
but it is unsupported). zfs compression has given me a serious
performance boost, except with oracle database, but that's because I
didn't match the zfs settings to the database and didn't have time to
play with this.
