I recently bought a DroboFS for the storage needs of my lab. It is a nice piece of hardware but I was extremely surprised to see that the only way to configure it is the Drobo Dashboard, a Windows/Mac binary that must be plugged in the same network as the DroboFS (it sends broadcast packets to locate the DroboFS and it is impossible just to give it the IP address).
Why no web interface, such as the one on the Iomega StorCenter Ix2, a much cheaper network drive ?
A recent project to develop a webdashboard (by a user, not the company) exists, but to this day there is very little code available.
Based on his code, I wrote a PHP page (dirty code as I used PHP only once in the last 10 years) that displays the data I was able to get from the share configuration and status data of the Drobo.
edit:anonymized screenshots
I still cannot add users, allow them to change their own password, add a share and change user rights, but that’s a start !
Here is the source code in the hope it might be useful to someone else.
Known bug : if you did not define any users in your DroboFS the status display will fail.
To use it : activate DroboApps on your DroboFS (with Dashboard), install the Apache droboapp, create the file droboStatus.php in the /DroboApps/apache/www directory and fill it with the code that follows. To see the result, just go to http://droboIP:8080/droboStatus.php with your browser.
