Product Description
Product Description
DroboPro is a storage array that manages itself. DroboPro is a rackmountable/desktop eight-drive storage array that protects against two simultaneous drive failures. Capacity expands by adding/replacing drives. DroboPro¿s BeyondRAID technology allows mixing different sized drives without sacrificing capacity. Connect to server via iSCSI/FireWire800/USB. It supports up to 16, 16TB volumes (LUNs). Includes iSCSI initiator and backup software.

Big Storage with Drobo Ease
Easily add up to 24TB of storage to a workstation or small office server without having to learn anything about storage administration. Just insert up to 8 disk drives into the DroboPro and the innovative BeyondRAID technology takes care of the rest. DroboPro is ideal for creative professionals, such as photographers and videographers, who have large amounts of rich media to store and protect. Also, DroboPro is an excellent alternative to internal RAID for a single server.
Up to 8 Disks of Instant Expansion to 24TB and Beyond
Grow your storage in line with your data capacity needs with minimal effort. To add capacity, simply insert a new hard disk drive or replace your smallest drive with a larger one, even when all eight drive bays are full. Unlike traditional RAID systems, the BeyondRAID technology in DroboPro enables you to mix and match disk brands, capacities, and speeds. This enables continuous expansion as drive capacities grow. With DroboPro expansion is automatic and instantaneous and access to data is always maintained.
Triple Interface Featuring iSCSI
Attach DroboPro directly to a workstation or small office server that requires high-capacity, protected storage. Interface options include Gigabit Ethernet (using iSCSI protocol), FireWire 800, and USB 2.0, with iSCSI providing the highest level of performance.
Unfamiliar with iSCSI? It's a high performance protocol that's become extremely popular for storage technology in IT environments, but it can often be complex to manage. DroboPro changes that by introducing zero-click iSCSI configuration for both Windows and Mac OS X.
Rack Mount Ready, Desktop Quiet
DroboPro is equally at home in a rack mount environment as it is on your desktop. Dual smart fans automatically manage their speeds to optimize both cooling and operating noise. (DroboPro rack mount sold separately.)
Smart Volumes with Thin Provisioning
Create new volumes in seconds and manage up to 16 x 16TB volumes over time with ease. The innovative and time-saving Smart Volume management technology with Thin Provisioning integrated into DroboPro allows volumes to pull storage from the common pool of disks rather than a specific physical disk allocation. The labor of re-sizing and migrating volumes is replaced with the simplicity of intelligent engineering.
Protection from Two Drive Failures
Enable the dual-drive redundancy option to protect your data from failure of up to two hard drives. It's all done with a single click and without ever losing access to your data. Running out of space? Switch back to single-drive redundancy at any time. Unlike moving between traditional RAID 5 and RAID 6, there's no need to reformat or migrate data from DroboPro, potentially saving you hours or days of downtime.

The product simply is no reliable and I would not recommend it. Save your money for the next generation which might have these problems fixed or for another solution that is proven.
Customer service is friendly and responds quickly but has been unable to resolve my issues as of yet. Hopefully my Drobo is defective and a new one will work as advertised.
I will update this review if my issue gets resolved.
-----Updated 3-3-10-------
So after a lot of testing and firmware updates the device still was pretty slow. The rebooting and crashing issues were resolved with a firmware release 2 months after my purchase. but it still was pretty slow with writes and semi unreliable when writing big chunks of data over a few hundred GB's. I have to say though that Drobo Tech support and customer service was very nice and easy to get a hold of. They ended up giving me a refund outside of Amazons typical 30 days and with no restocking fee. Also I know other people out there have had good luck with their Drobo's so my problems may not have been typical. So if you're considering this product I would say go for it since they stand behind their devices and will issue a refund if they can't make it work for you.
Also note that I have a Drobo 2nd gen that has been going 24/7 for a year and is working great. I even had a drive die in it and it worked as advertised, it sent me an email alerting me to the failure and began doing its thing making my data safe again on the other installed drives. They also are pretty frequent with updates for the dashboard software and firmware so if something is a little off it's likely they are aware and working on it.
Maybe I'll try the new SATA Drobo or get another 2nd gen. All said I would not buy this specific drobo again but will definitely consider their other products in the future.
Honestly, it's not terrible, but my experience overall made me return the unit at the end of the following day.
Here is why.
I was installing this as an iSCSI target. I have a lot of experience with iSCSI on Linux, BSD, Solaris, and Windows.
The DroboPro behaves like NO OTHER iSCSI target I have EVER worked with. The DroboDashboard software couldn't find it on our network, ever.
Open-iSCSI running on Debian Linux found it without issue though after I had preconfigured it over Firewire.
Here's where the real headaches started. DroboPro does not "officially" support more than 2TB LUNs formatted with EXT3, no matter what disks you use.
DroboPro doesn't support anything other than HFS+, NTFS, FAT32, and "unofficially" EXT3.
Never mind that an iSCSI target should be completely indifferent about what the filesystem used on it is, nor should it particularly care what size the LUN is.
DroboPro fails this point so badly it's disastrous. I tried 16TB with EXT4, it appeared to work until I went to actually mount the filesystem and then I get tons of iSCSI errors and eventually had to kill the process.
These are likely limitations brought on by their fake-raid. It's a goofy way of managing an array, you don't actually get any control over it.
Instead you decide what size your LUNs will be - they'll all be that size. Then "feed it disks".
So now having discovered this the hard way after hours of troubleshooting iSCSI failures caused by this thing not understanding what I felt was pretty basic task [1 LUN, 16TB, EXT4] I come to find that the problems are all caused by Drobo's lack of functionality as a block device.
Do not purchase any Drobo equipment if you want your data to be safe. In their documentation they constantly stress the need for backups... wonder why.
This might be fine for the Mac weenie as a large timecapule (I've heard bad things in this regard too though!) but for a real production SAN... RUN the other direction.
While looking for solutions to my problems with this I came across a bunch of people who had various issues related to DroboPro/Elite iSCSI reliability across pretty much all platforms used with it - Linux, VMware (ESX/ESXi), Windows, Mac. Nearly all of the complaints were about slow I/O under heavy load or complete disconnects seemingly at random.
You'll be better off with a SansDigital EliteRaid iSCSI -- TRUST me. They do everything from the $200 two drive portable unit all the way up to "Enterprise grade" 50 drive RAID6/60 monster for $60K.
This review was written immediately after finally giving up on the product and returning it to Amazon - as such it may be a little confusing and sound frustrated.
I hope this saves someone else from a similar experience.
I do love Amazon's return policy though!
