IBM Planning 120PB Cluster Array.

Saw this linked elsewhere, but:

Now that's a lot of pr0n...

Damn...the noise and vibrations must be intense.

Several Terabytes per second. Sweet. I wonder what kind of SSD cache they have strapped on the front end?

 

[Handruin]

It sounded like those transfer rates were a benefit of their custom filesystem. There is certainly that issue with the more data you store, the faster you need to read and write to make it worth accessing.

 

[ddrueding]

Indeed. If you connected a single SATA 3.0 link to 120PB, it would take 5.3 years to fill it.

I wonder what hard drives they are using?

Why wouldn't they just use DRAM as normal?

2.5" form factor for starters. Aren't Seagate and Hitachi the main enterprise drive manufacturers?

 

[LunarMist]

Then they will be WD-Hitachi or the Seagate drives?

Maybe DD expects OCZ.

Considering everything in that kind of rig needs to be redundant anyway, just get the fastest you can and let 'er rip.

just get the fastest you can and let 'er rip.

Except when 30% of the drives decide to fail at the exact same moment, and you're left with a slow-a*s array due to all the rebuilds taking place.
