Haha, sorry about that, I've been reading through the opensolaris forums to see what looks like a good solution when I'm ready to expand, which is where I found out about the quirks of those LSI cards. I'll probably wait until the 2TB green drives drop to $200 or so, and then get some variety...
Well, I'm assuming Mage didn't flash his card either, so he would have the same issues. The IT firmware isn't just an update, it's a completely different version of the firmware that doesn't have raid. It presents bare drives to the system, and skips all of the raid functionality, you don't...
From my general understanding, every LSI controller listed here http://www.lsi.com/storage_home/products_home/host_bus_adapters/sas_hbas/index.html is able to present "bare" drives to the system and act as a dumb HBA. That makes them attractive for ZFS, and I would imagine likewise for WHS...
What OS?
You might want to figure out what SAS card you're going to use, the M2N-LR has 2 PCI-X slots, but if you're going to drop the money on a HW Areca card, you might as well go PCIe and skip over the older tech.
That Corsair seems unnecessarily expensive. I don't know what the...
I think they're still referring to the LSI 8308ELP, seems to use an Intel IOP333. I would be interested to see if it works in 2009.06.
Otherwise the currently supported LSI cards that look good are the LSI SAS 3081E-R (2x 8087), and the 3041E-R (1x 8087). They use the same LSI 1068E chip...
Through a UPS, but the readings on those can be off as well. I checked it on a Kill-A-Watt once and FWIW, it did read a bit lower. Regardless, a system with a largely idle 45W processor and a few disks won't pull enough to justify a 550W supply. The corsair unit is a good one, it's been on...
Power consumption is the name of the game for an always-on server. Any of the 45W dual core processors are more than fast enough for WHS. No point in putting a 95W Phenom reject in a file server.
A 550W power supply is also massive overkill. You want to hit at least 20% load to get in the...
NFS seems to be the best option for OSX. It's a bit easier to get up and running than CIFS, and it's a bit faster normally.
Hardware wise just be careful with support, as opensolaris can be picky at times. A 64 bit processor is highly recommended and the more ram the better, 2GB is good...
Well it depends on what electricity costs are in your area along with the heat and noise considerations. The 1TB Green drives idle around 2.8W, the Blacks around 6.5W. Depends how much the extra 2 yr warranty means to you. If you're only serving a few users than you can get away with PCI-X on...
As far as I know there's no real limit on disks in a vdev or a zpool. It's also probably not recommended to go over 6 or 8 drives in a raidz due to the possibility of losing 2+ disks at the same time or during the resilvering (rebuild) process. Check out the ZFS Best Practices guide, it has...
The AOC-USAS-L8i (~$120) has been out for a while, what's the advantage of this new card?
