If you could expand on your post, I'm very curious about it. 2 Petabytes? 32 Petabytes? Where do you store that kind of information? For ther former you would need something like 2048 teraservers, just the power requirements are scary. How do you back it all up?

"For ther former you would need something like 2048 teraservers" ... or a few modern SAN storage arrays. There are 500TB off-the-shelf solutions available, and I'm sure the manufacturers will be happy to sell you bigger custom variants.

actually, you can get a petabyte of storage for ~$2m off-the-shelf that fits in ~4 racks consuming ~30KW of power

buy 40 Sun x4500 servers ( http://store.sun.com/CMTemplate/CEServlet?process=SunStor... ) each with 24TB storage, 2 dual-core opterons, and 16G ram

so 2PB of storage are $4m in 8 racks (80 servers) consuming ~60KW. that's not too scary (although it is quite a bit)

backups are an issue, my guess is that the backup is mirroring to another similar set.
