Parent article: Ext3 for large filesystems

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 ( ) 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.
