Cracking Open the Drobo B800i
The Data Robotics Drobo B800i is an 8-bay, iSCSI SAN storage device that's designed for small and medium business environments. It can handle up to eight, 3TB drives for "up to 24TB of raw storage."
TechRepublic's Mark Kaelin reviewed the Drobo B800i back in June, and I couldn't wait to crack it open.
For an in-depth analysis of the Drobo B800i's internal hardware, check out my post, "Drobo B800i SAN storage device teardown: Proprietary motherboard with Marvell processor".

I am troubleshooting an obsolete DROBO four bay unit. I have it down to where I think the problem is in the USB input circuit -- perhaps a three terminal regulator. Running the part number (IR P730G M7) on a search doesn't turn up with any help. I could really use any info on the schematic, parts list, etc... Is there any help available?
As the small CR2032 would power the CMOS type settings, I guess the 3.7V, 7500mAh Li-ion battery pack must act as a temporary UPS to allow the unit to handle sudden loss of power while writing data?
what's wrong with fig. 24? a pair of long-nose pliers to do the job for a screwdriver??? well, well, well, aren't we macgyver-ish? :)
Sadly, Bill, the forest of advertising that has been allow to cultivate around your deconstructions has made an enjoyable diversion not worth it any more. When the subject of the page occupies less than the ad space, it's time to bail. Have fun with future Cracking Open episodes with 1 less interested party. Tom
I used the needle-nose pliers to compress the split end of the post, which held the PCB to the metal frame.
Not for nothing desert.. but this is a business. They are out to make a profit. I certainly do not fault them for that. I enjoy everything TR posts, ads or no ads.
I'll pass along your comments to our Web design and engineering groups. We're currently working on a redesigned gallery page that will make it easier to flip through the images.
havign to scroll down a screen to get to the picture makes it very unsatisfying another one who will not bother to look in the future david
Below the TechRepublic Search box (top right-hand corner) there is a link that either reads "Collapse" or "Expand". This link controls the three image-based content promo boxes that appear immediately below the blue navigation bar. We are in the process of redesigning the gallery page--hopefully making it easier to flip through the images. But, I hope this helps a bit for now.
