For a home grown setup, it sounds ok.
8 disks on a controller might be too many... depends. Obviously, a LOT of standalone subystems have FAR fewer controllers.
I would think you'd get some pretty nice numbers off of it. Would you consider getting yourself setup on the Phoronix Test Suite (run the disk benchmark)? I wouldn't also mind seeing some bonnie++ benchmarks (make sure you include the version you used).
Your RAID 10.... how did you create that? Is that somehow coordinated using the 3ware RAID driver only.... or combination of 3ware RAID level plus Linux md? Just curious.
Also... (just thinking out loud)... this box might want more memory. Again, it depends on how/what the storage is being used for. For example, if this were to become a NAS box on a 10Gbit network, performance could go way up with more memory. Post some benchies... would love to see them.
Oh.. have you simulated a drive failure yet? A multi-drive RAID 10 failure? I think those are good tests.... just to make sure you really have a workable RAID10 on your hands.

Sent by: linux-lvm-bounces@redhat.com
Hey all,
I've made a storage by myself.
This box has 24x 1,5T SATA II disks, 3 controllers 3ware
PCI-Express,6G ram memory DDR3 1333Mhz. This disks are distributed for
each controller, 8 disks for each one. I've done at each controller
Raid 10 with 256k stripe size, then I've created one volume group with
all disks and I've created one logical volume with 10G, 3 stripes and
256k of stripe size. I've gotten a great result with it, but i'd like
to know what all think about it.
Sorry my last e-mail, I'm falling asleep and i've sent unintentionally.
Thanks all,
Fabricio
