hello
my suggestion of a big and really cheap system
(use dev build or next release 03.2010)
mainboard

ecc, max 32 ram, intel 3420 server chipset, vga, 3x pci-e, 6 x sata
in germany about 180 euro
3 x sas controller lsi1068
Yes, if I was to re-do the hardware config for these servers, using what I know
now, I would do things a little differently:
- multiple 8-port SATA controllers
- 1 vdev per controller
- 6-drive raidz2 vdevs
- find a case with more than 24 drive bays (any way to get a Thumper without

It's called the
SAS disks more expensive. Besides, there is no 2Tb SAS 7200 drives on market
yet.
Seagate released a 2 TB SAS drive last year.

Yes, it was announced. But it is not available in Russia yet.

3Ware 9650SE PCIe RAID controller (12-port, muli-lane)

Fully supported by FreeBSD, so everything should work with
OpenSolaris.
FWIW, I've used the 9650SE with 16 ports in OpenSolaris 2008.11
Hello.
Thanks for config, but Chenbro badly widespread here, in Russia.
As for 3Ware RAID cards i think better get dumb HBA cards and let ZFS
do all work.

That must be a combination of many things to make it happen.
ie. expander revision, SAS HBA revision, firmware, disk model, firmware, etc.
I didn't see the problem on my system but I haven't used SATA disks with it so
I can't say.

Hello.
We need big cheap storage.
Looking to Supermicro systems.
Something based on SC846E1-R900 case
http://www.supermicro.com/products/chassis/4U/846/SC846E1-R900.cfm with 24 disc
bays. This case with 3 GBit LSI SASX36 expander.
But the problem with LSI based HBA timeouts really confuses me.
I have Supermicro 936E1 (X28 expander chip) and LSI
1068 HBA. I never got timeout issue but I'm using
Seagate 15K.7 SAS. SATA might be different as it
handles error and io timeout differently. If you
still want volume, you make take a look at 7200 RPM
SAS version.
SAS disks more expensive.
We use the following for our storage servers:
Chenbro 5U chassis (24 hot-swap drive bays)
1350 watt 4-way redundant PSU
Tyan h200M motherboard (S3992)
2x dual-core AMD Opteron 2200-series CPUs
8 GB ECC DDR2-SDRAM
4-port Intel PRO/1000MT NIC (PCIe)
3Ware 9550SXU PCI-X RAID controller (12-port,
