I beg to differ.
I bought a Drobo Pro and returned it.
It had a number of faults most notably really poor performance, no support for Ext4, only 1 GigE port and no ability to share it.

Sorry, an extra $2000 for a GigE port and the ability to share it?
Are they serious?

Also, their thin provisioning you tout as a great feature has left some users locked out of their data when the Drobo wrote too much data to the array.

I can buy a very fast hardware RAID card and a SAS external box for $1000.
I can spend $1600 on a fast NAS box like the Qnap 809 Turbo and have 2 different RAID options that outperform a Dodo and still have $900 left to spend on drives...

Oh wait, that's just what I did.
The hardware RAID connected to my Mac is blisteringly fast 800MB/s+ and the Qnap sharing NFS is saturating the GigE LAN.

The Dodo Pro could manage 70MB/s when connected directly to the Mac and more like 20MB/s - 30MB/s when shared.

Hey Evil Ted,

Well - let's be candid here. The Drobo Pro wasn't meant to be shared - it is positioned as a single server solution - so your bad on that one.

The new Drobo Elite on the other hand was designed to be shared.

From a performance perspective - I have no idea what application that you're running so I can't comment. But again, I don't think anyone claims that Drobo is the high performance storage solution. I didn't mention performance once in my blog.

Additionally, since you are trying to use ext4 - you are not probably not the target audience. It is unlikely that many of the Drobo users will even know what ext4 is. But I must point out again that this was your fault for not doing the research ahead of time because it is pretty easy to find out that Drobo doesn't support ext4.

Also - not sure if you really read my blog because I didn't say anything about thin provisioning.

Clearly you are technical - so your particular comfort level with managing a RAID system and integrating a NAS layer is okay for you. But for the multitude of customers that I am taking about that are out there - the blue ocean I referred to - doing what you described would be an uphill battle at best.

Drobo is not for you and not going to be good for every application. But they will soon hit over 100,000 units in the market. I know lots of people personally that use the Drobo (including me) - so clearly there are customers out there that want the ease of use and transparency that I discussed above.

I have been in the industry for a long time - and there is negative feedback about EVERYTHING out there. Nothing is a panacea and no product is perfect for everyone. I was attempting to point out in my blog the core value proposition of the Drobo and Beyond RAID - and none of your points seem to refute what I was saying. Rather, it just wasn't suitable for your needs. You don't want or need the ease of use and management - lots of others do.

Note from Tony Asaro - Interestingly, Colin is the first to comment on the blog and negatively at that. But he represents the "storage" person I spoke of - that doesn't get the value of Drobo - because he is good at integrating technology.

However, for the small business owner that runs their own IT (Drobo and Drobo Pro) - all the way to the Windows admin in a 100 to 500 person company that needs shared storage (Drobo Elite) - the transparency and ease of use are essential for this blue ocean market.

(Btw I know a number of storage people that have and use Drobo and they are pretty high on it as well)

I believe that a million storage systems will be running the Drobo technology in the foreseeable future. And the only way you get to those levels is by what I said earlier - requiring no skill to operate the device.

Jeez Ted!

So someone had an accident because he did walk over the street while the lights where red now they shout at the lights?

Its the same with Drobo: If you ignore Drobo (and any other thin provisioned storage for that matter) telling you that you should add capacity and you refuse to do so you shouldn't cry if you loose data.

Seen stuff like this in bigger companies with SANs in the 7 figures price range.

Tom - I don't know Colin's specific situation or the users he is referring to but I like your analogy.

Thanks,

EvilTed/Colin, I think you're missing Tony's point. Sure you can get better performance on your Qnap 809 Turbo, but the Drobo wins in ease of use.

Let's say you buy a couple of 1.5TB disks now since all you need is some added storage with RAID1. After a few months, you decide you need more capacity and 2TB drives have begun to offer the best bang-for-the-buck. You add a 2TB drive to your Qnap 809 and you'd have to re-build your array in RAID5 and then copy over all your files from your external back-up. With the Drobo, you stick in the drive and you can start using that extra capacity.

I haven't seen any other storage solution that does that, but if you find something, post it here.

I agree that the lack of support for ext4 sucks and it'd be great if they provided OFFICIAL support for Linux.

I agree that Drobo has nice features. You can easily grow your storage without worrying about the typical problems and complexities. Just add larger and larger disks, simply by watching the blinky lights!

Have you looked at other vendors that have done this same thing? What are your opinions of them compared to Drobo?

It looks like Netgear's ReadyNas XRAID2 does the same thing:

Also, it looks like QNAP does something similar as well.

Both of these products are much cheaper than the Drobo.

Thanks for you input!

I think that storage people aren't that thrilled about the Drobo because it's a consumer targeted product. In that space, I think the Drobo is a winner.

I don't think your parallel with VMware is a terrific one. That kind of virtualization abstracts an OS instance from the actual hardware it's running on. The Drobo doesn't quite do that. It provides storage redundancy (a good thing), makes the hardware array independent of specific drive sizes (a neat thing), and has software management which allows automatic upgrading of the array (also neat).

Ease of use and continuous upgrades are good design goals, but I think an enterprise storage guy is also worried about tiered performance, single points of failure, multi-chassis expansion, silent data corruption, enterprise apps, multiple host connections, filesystem support, data snapshots, raw drive access, intelligent cache utilization, enterprise support, etc.

Just ... different concerns.
