IBM Building 120PB Drive, World’s Largest

IBM Building 120PB Drive, World’s Largest

Researchers at IBM’s Almaden, CA research facility are building a storage drive of monstrous proportions, a machination comprised of 200,000 hard disks that equals 120PB. So yes, it can house your entire digital music and HD video collection, as well as tens of thousands of copies of it.

The drive is designed to run the huge, complex simulations needed to research things like climate change and molecular study.



In order to make such a project work, the IBMers had to innovate. For example, the racks are densely populated with hard disks, creating a heat problem that the team solved by using water cooling instead of fans. Further, in order to prevent data loss, when a disk fails, the redundant data stored on other disks is slowly copied onto the failed disk’s replacement, which doesn’t really affect performance; if multiple nearby disks fail, that process is sped up to prevent any permanent data loss.

Purportedly, the 120PB drive will not lose any data or see an impact in performance for one million years.

Size, of course, is one thing, but speed is another. In order to boost performance, IBM is leveraging software, such as its own GPFS file system that it designed specifically for supercomputing applications.

IBM innovating again... :rolleyes:

Maybe they should have had 'Watson' look up SAN and RAID.

As for the 1 million year data and performance promise... no comment as you can't successfully argue with insanity.

Are they having trouble selling their 500GB drives and has 200K of them laying around

IBM being IBM as usual.

BTW:  HDS VSP scales to 'Up to 255PB of total storage capacity under management'

Personally I think this is really cool. IBM is often creating ground breaking projects. What the hell are they using to connect all these drives together.

Dave/Marco do you think you can get one of these for testing/benchmarking Stick out tongue

Hmm... we could try but I'm not sure if we can fit it in the lab! :)

I'm not sure you can even get one; unless you have a medical/chemistry degree or been on TV as a local weatherman.

Maybe Marco could offer to trade that new ASUS Video Card for it?

@realneil Dave would have to pry it from his cold dead hands in order to offer it up as a trade :)

I'm really glad that they are using liquid cooling!  I hope that more companies follow suit and develop commercial applications.  The heat transfer efficiency is just so much better than air cooling.

yay!

Sure looks like 120 petabytes+ may be the norm for cloud computing in a short time
