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
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
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
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
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
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.

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.

If you are planning to use this device as a enterprise critical storage target via iSCSI - forget it.

Don't buy the Drobo Pro, save some money and buy a better product at the same time, get the Areca ARC-5040 and you won't be sorry.

Dead simple to use compared to any other RAID-ish system I've seen, and more flexible. You can mix drive sizes and it (usually) makes good use of the space (be sure to prototype your configuration first using their online drive calculator). Plus you can replace small drives with larger drives on-the-fly. Rad.

The network iSCSI connection is more than fast enough to edit several simultaneous streams of video.

Some issues:

1. It only supports HFS+ volumes up to 16TB. According to Apple's Technical Note TN1150, HFS+ can technically support volumes up to 8 Exbibytes, so this seems like an arbitrarily low limitation on the part of the DroboPro. I'd rather just create a single humongous volume, and keep expanding actual capacity as larger drives appear, instead of creating multiple 16TB volumes...

2. It doesn't perform Data Scrubbing. So if data gets silently corrupted by bad harddrives, I probably won't know about it until it's too late -- whereas with proactive Data Scrubbing (like that provided by ZFS, for example), inconsistent blocks could be automatically blacklisted.

With these two issues solved, the DroboPro would be perfect.

Storage innovation has been ongoing over the years, but there hasn't been a whole lot of "new stuff" lately, and at price points like this, there hasn't been much change at all. Traditionally if you wanted to buy a cheap disk shelf, you'd be looking at something from Apple (discontinued), Promise, possibly Adaptec, NetGear, Iomega for a cheap 1u-style NAS head--at perhaps 4x-8x the price of this Drobo Pro.

But this isn't a NAS head, and it contains 8 drives (though it works fine with fewer). Instead, you're buying a block device that you can use over iSCSI, FW800, or USB.

The key benefit Drobo is selling is the zero management of RAID and volumes and the Drobo Pro delivers on this in a massive scale. Growing a volume is as simple as adding another disk (or swapping out the indicated disk with a larger one). The concepts of RAID-5 or RAID-6 need not be understood or considered by the user other than a checkbox of "do you want this thing to survive two concurrent drive failures?". Rebuilding is taken care of.

Drobo comes with a simple GUI to monitor capacity, show overhead for protection, configure email alerts. I did run into an issue where Drobo wouldn't work with my internal mail server due to a TLS problem, which I haven't debugged much--the mail server supports TLS, so I am not sure what the problem is. The iSCSI set-up was dead easy for me--I plugged in the Drobo with USB (just to get it configured), set the iSCSI IP address, moved the Drobo to the network closet and plugged in Ethernet, and the Mac automatically found and mounted the Drobo volume.

The construction of the unit is solid. It weighs a beefy 20 lbs (empty), and the fit and finish is superb.

I've heard good feedback on Drobo products but after trying a Drobo Pro we had a lot of problems. The first unit we tested performance was 20-30mb/s with frequent "freeze ups" where it would drop down to 5mb/s. Local storage on this same box gives 130mb/s with single raptor drives.

We got a replacement unit that was completely dysfunctional, it rebooted continuously and was not functional. The third unit a technician received and tested before sending to us. We managed to get 90MB/s out of it for about 5 minutes, then the device dropped down to 60Mb/s on average, still with random drops to 5mb/s (although not nearly as often as first unit but still frequently happens coming out of drive spin down). These tests are with 256K block size, I always test with 32K block size, but when using 32K block size, performance was really low (6-8Mb/s or so). This is tested with 8x Western Digital Black Dual Processor Drives w/ 32MB cache. The tech I spoke to only had odd drives like old 40GB drives to test with and did not have any reasonable performance drives in the lab.

The first device was extremely difficult to use, if for whatever reason you put the unit in standby you can fiddle with it for 15 minutes before it would eventually come online, many times only with a reboot. The new unit seems more reliable in this manor, but still can be quirky.

The software is super easy, and it is really designed to be dummy proof, but not as much for VMWare, Multiple Servers, or anything performance sensitive. It typically performs slower than an average single sata drive. Although they are marketing it for VMWare and corporate environments. A big part of this is due to the 256MB memory on the device, where only 64MB is reserved for write-cache.

On paper the Drobo Pro is great, an 8-bay raid box that can take care of it self. In reality however, it's not very good. I wasn't expecting blazing fast speed, but I wasn't ready for this. Connected via Fire Wire 800 my Drobo managed to sustain a 30mbps write speed (Fire Wire 800 is capable of 800mbps), and when you have over 6TB (yes, terabytes) of data to backup this kind of speed is unacceptable. I'm a video pro who needs lots of storage space and lots of speed, however I don't need all of my old footage on my super fast edit raid, hence the Drobo, lots of space and redundancy to protect my data. However, it took my Drobo several days to complete the backup and finish what it calls "Data protection", it's just too slow, and I can't even play back video files. Overall I'm deeply unsatisfied with the Drobo. If you are looking for an 8-bay storage device I would suggest you buy the Areca ARC-5040 Raid Box. Like the Drobo pro it has 8-bays, and it has a host of advanced features that enable you to have it grow over time like the Drobo. However the Areca has dedicated hardware raid built into it, so it can perform like a real raid should, it's fast, easy to use, and costs less than the Drobo Pro.
Don't buy the Drobo Pro, save some money and buy a better product at the same time, get the Areca ARC-5040 and you won't be sorry.
P.S. The ARC-5040 isn't currently available on Amazon (they don't sell it), look at NewEgg, they have it in stock.

UPDATE: 11/20/2010
Made the mistake of updating the firmware on my Drobo Pro, now it's dead. After the firmware updated Firewire stopped working, so it was connected via USB. Once it remounted it needed to perform "Data Protection", this went on for TWO weeks, until it crashed.
