The famous but illusive 33 petabyte system

(1/1)

Lars Bencze:
Hi all,

I believe I once saw a technical description of the famous OnDemand system, which allegedly holds 33 petabyte of document data on a standalone server.
But I cannot find it anymore. Does anyone have a link to where I can find detailed info on the setup of that system?

Justin Derrick:
The largest one I'm aware of is/was in the low-single-digit petabyte range.  I would suspect that the number might have been 3.3 Petabytes...  33 sounds unfathomably large, even for CMOD.

True, but still, IBM likes to brag 8) tell about it - here's a quote by Brian Phelps, available online:

--- Quote ---IBM has thousands of archive and retrieval customers using CM OnDemand (CMOD), the largest of which has over 33 petabytes under management, with many others in the same size range.

Perhaps I misrecall slightly - 33 Petabytes is the max size one vendor's Storage repository can handle, and maybe it was 33 Billion documents in one system? Or Trillion ??? Anyways it was a huge number, that's for sure.
