It was confirmed recently that apple bought 12 petabytes of isilon storage.<p>Assuming the offering of ~3GB per cloud user, that is enough for up to 4 million accounts.<p>Given that their DC is 400,000 SF -- and the aerial view suggests at least two zones, it is pretty clear what and how they are offering this.<p>What would be interesting is if this offering is just integrated into iTunes and the new OS -- as would make sense.<p>If you have an iTunes account, you jsut have 3gb storage that now comes with it.<p>Accessible from any apple device you own - like your iPad and iPhone - your content is seamlessly accessible across three platforms + the web.<p>Obvious play.
