Sounds awfully expensive. True?
Most of them are, but you can add whole shelves of disks. I'm not sure
it matters so much in a case that holds six drives that you fill from
the start and then have nowhere to grow anyway.
The guy who initially asked, IIRC, wanted some 3-4TB storage. This can be
accomplished easily with a regular mid/maxi-size tower and a handful of
1TB-SATA drives. Even the midsize oldish Compucase-case I have at home can fit
four 3,5"-drives in the hd-cage and another four in the 5,25"-bays. Suppose
you fill that case with 1TB-drives and you have 8TB available. My argument is
that there is no explicit need for the hardware you mention, despite how sexy
it sounds. 8-)
My understanding was that he wanted some kind mid-level kind of storage
solution based on hw he already had and not sink the entire budget on a
roomful of EMC etc hardware. OTOH, this discussion has been a bit sidetracked
since the beginning. 8-)

Hi Sorin,
You're quite right with what you say. I have a 2U chassis already, with
a Gigabyte motherboard + 2GB RAM + Core 2 Duo E7650. I also have a few
160GB SATA HDD's laying around, but they're too small. So, I'll be
option to put 6 (if I can get the HDD cages fitted into the chassis) 1TB
HDD's into it instead, which with RAID 10 will give me 3TB space.
Thus, I don't want to spend more money to buy new equipment if I have
this already.
Using CentOS is preferred since I know it the best. I haven't used
FreeBSD since v4.7 ( I think I had a look @ 4.9 & 5.4 as well), and I
don't know Solaris.
I think my action plan now will be to figure out how to install CentOS
on a USB memory stick and make it boot on any machine (making it easy to
replace if need be), and then to play around with the RAID a bit and see
how well it works.
