IBM builds largest disk array ever

Hard-Disk-Drive-1There is RAID and then there is RAID!. Well IBM has the latter that is a conglomerate of 200,000 disk drives combined together to make up a 120 Petabyte (not to be confused with Pedabite which has to do with chewing on feet) drive array. IBM built this to accumulate data for weather simulations. We imagine that these would be more than answering what the temp will be on Monday but will likely be for long-term forecast models and of course everyone favorite; global warming.

The array is going to an as yet unnamed client of IBM’s but IBM did say that one day (in the far far future maybe) cloud systems would all have similar storage arrays. For those interested this is not a giant JBOD or even RAID 50 array. This is something new called GPFS that allows the system to almost self-heal. If a single disk begins to fail the system can move the data slowly to a ready spare without the normal rebuild times you expect from other arrays. It can also spread files across multiple disks allow extremely fast read/write/index times.

I wonder if I can put something like this together in the garage…
