Drobo B800i SAN storage device teardown: Proprietary motherboard with Marvell processor

In your last sentence before the observations, I think you meant to say "shouldn't"

When someone says that "the manufacturer will likely be your only source for the proprietary hardware," then you should be very wary if my experience a couple years ago with an NAS drive is any indication. There may not be any fixing the thing when it craps-out in a couple years.

I'm just not getting it. I could self-build using Freenas for about $500 before hard drives (it's what I plan to do). I truly don't get what the other $3000 is going to buy me. Can anyone help? Especially since i will use "off the shelf" parts and can easily replace them myself with other non-proprietary parts whenever needed.

Proprietary? What isn't in PCs these days? Is there such a thing as a non-proprietary circuit board for a NAS? The only thing not proprietary about PC motherboards is the mounting hole placement. Even the I/O panel is unique to each motherboard. That is why the cases have a standard rectangle opening and the mobo maker supplies the insert.

No reason to ding a product because you need to get the circuit board from them.

I had very high hopes for Drobo devices, even the VMware certified units couldn't hold a match to basic direct attached storage. I have tested DroboS, DroboPro, and DroboElite units and found that when you really beat on them, especially with a Vmware esx host running a few load testing VMs, they fall over and lock up - requiring a manual poke in the eye to come back online.

While I look at the 800 and 1200 units optimistically, I'm not sure I would recommend them for any VMware use as I've found the vmware certification to be useless in this case. It doesn't appear they've invested any more into their controller's processor or storage subsystems.

I love being able to use different size drives and then get an automated rebuild, but you pay a premium.

Thanks, Colin. http://www.mackellar.net

they must be prepare huge storage device with less execute time fetching by operation server beispiel" DAS MOBILE WEB" window server2008 R2 or more requirement with more than one interface language-bar ,also be less price to be every body can owner.

Well done! Thank you very much for professional templates and community edition
