DroboPro™ is the first business class storage array that manages itself. Engineered to be both simple and scalable, the revolutionary BeyondRAID™ technology incorporated into DroboPro frees businesses from making the difficult and confining choices commonly associated with storage management. Why trade simplicity for safety, or stability for expandability? DroboPro delivers both enterprise-level data safety and unprecedented expandability, featuring single and dual disk redundancy combined with instant capacity expansion. Once you experience DroboPro, you just might forget the differences between all eleven traditional RAID levels. If you do, don't panic. You're experiencing the peace of mind that comes with every Drobo® product. |
Up to 8 Disks of Instant Expansion to 16TB and Beyond
 Grow your storage in line with your data capacity needs with minimal effort. To add capacity, simply insert a new hard disk or replace your smallest disk with a larger one, even when all eight disk bays are full. Unlike traditional RAID systems, the BeyondRAID technology found in DroboPro enables you to efficiently mix and match disk brands, capacities and speeds. This allows for continuous expansion as disk capacities grow. With DroboPro expansion is automatic, instantaneous, and access to data is always maintained.
No Headache Dual Disk Redundancy
The DroboPro Dual Disk Redundancy option protects against the simultaneous failure of up to two hard disks. It's all done with a single click, without ever losing access to their data. Running out of space? Switch DroboPro back to single disk redundancy with a click. Unlike moving between RAID 5 and RAID 6, there’s no need to reformat or migrate data off of the array, potentially saving hours or days.
Triple Interface Featuring iSCSI
DroboPro attaches directly to a server or workstation that requires storage, or to a shared server or workstation on a network that can provide access to multiple clients. Interface options include:
  iSCSI (using Gigabit Ethernet)
- FireWire 800
- USB 2.0
Unfamiliar with iSCSI? It's a high performance protocol that has become extremely popular with businesses, but it can often be complex to manage. DroboPro reduces the complexity of iSCSI by introducing zero configuration connection establishment for both Windows and Intel-based Macs running OS X. |
The Virtues of Smart Volumes
Smart Volumes allow customers to create new volumes in seconds and manage 16TB volumes over time with ease. The timesaving Smart Volume management technology integrated into DroboPro allows volumes to pull storage from the common pool of disks rather than a specific physical disk allocation. The labor of resizing and migrating volumes is replaced with the simplicity of intelligent engineering.
Rack Mount Ready, Desktop Quiet
 DroboPro fits into a rack mount environment or can sit on a desktop. Dual smart fans automatically manage their speed to optimize both cooling and operating noise. (DroboPro rack-mount sold separately.)
BeyondRAID lerverages the same underlying data protection methodologies as traditional RAID, including mirroring and striping with parity; however, BeyondRAID applies these algorithms on top of a robust and flexible storage virtual platform. This allows for the removal of limitations and drawbacks normally associated with RAID.
Key Benefits of BeyondRAID include
- Data protection against hard disk failure
- Instant capacity expansion without downtime
- Self-management
- Automatic healing
