It was confirmed here - http://arstechnica.com/civis/viewtopic.php?p=22587440#p22587440 - by IntelEnthusiast (who verified it internally @ Intel) that the combination can work. So at least the potential is there. (Assuming you are running a C20X series chipset)

Raid-5 is a red herring. You should be running Raid-6/Raid-Z2 with large 2TB + disks anyway. If we are only talking 2-3TB of data then sure, just mirror it with two drives - but assuming we are talking multi disk arrays just run 2 parity disks and you will be fine.

Multiple parity drives. With Raid-6 or Raidz2/z3 and reasonably sized pools (8-10) drives your chance of actually loosing data are pretty miniscule (you are probably more likely to be robbed). As for monitoring - an email letting you know there is a problem should be supported by just...

No, not 20TB, but I do have 12 256gig micron SSD's running a 1.5TB pool (all 2-way mirrors) as a VM host datastore. Your original post said "Given a example of a 2T Pool, VMWare use case". If that *isn't* representative of your requirements/setup why did you bring it up? But...

I wouldn't neccecarily agree with that - for typical VM hosting I find that SSD's actually scale reasonably well - and excellently when you take performance into consideration. Bulk VM storage requirements aren't really that great - and as long as you keep your bulk data out of the VM image...

I have two of these: http://www.addonics.com/products/mst.php with the Infiniband mutlilane card connected to an PERC H200 (sas 2008 chipset) via 2 CX4 <-> SFF-8087 cables. You could do the same with a IBM M1015. It was the cheapest way I could find to get 8 full speed external ports...

Install a drive in the desktop, share it out, and backup laptop to the share? That's probably going to be the cheapest option. If sleep status is an issue you can probably configure wake on lan, or schedule a wakeup timer.

Thanks - hadn't actually caught that portion of it - so in practice it becomes similar to drive extender in whs2003 (though the implementation is different). I expect it's also doing some sort of dynamic relocation on the back end to "balance" the drives when you add a new drive (otherwise you...

I'm a bit confused - if you start with a 2 way mirror, then add a third drive, and it's *not* a parity setup, what exactly is it? (assuming we are protected from any drive failing).

2 of the 16i LSI cards would give you 32 ports for < 800. That's not to say the expander can't work - it should - but I would go with native HBA's just to cut down on the variables (just an opinion of course though)

The DD identification method works if you have individual disk activity lights (norco cases, etc.) -- if you don't just reference via the serial number on the disk (at least that was the easiest way for me). Yep, napp-it supports sending email alerts on errors - look under the jobs tab.

I would replace the SAS expander with 2 flashed m1015's, or one LSI 16i (16 port) cards (http://www.newegg.com/Product/Product.aspx?Item=N82E16816118142 ) - depending on how many PCIe slots you have available. The 2 flashed m1015's are probably cheaper than the expander card anyway - and you...

It hardly seems worthwile for a 2TB pool - that's small enough that you could easily put together a pool comprised of, say, 256Gig crucial M4 SSD mirrors (~6000 dollars for 16 drives gives you 2TB usable with 8 mirrors). At that point the performance you get is going to tremendously...

Windows 8 is a pretty significant change, so there will be some relearning there as well. That said, it looks like you should be fine as long as you stay away from the parity spaces. Run mirrors (multiple 2 disk mirrors) all in the same "space" - should be equivalent to raid10 (though it looks...

From a point of view of someone not involved in the discussion it appears to me that the issue/position is more fundamental than that - * Has oracle uncovered and fixed "the problem" ** This really requires someone who could reproduce the problem previously to now run Oracle 11 and see if...
