Update 2: Sorting 1 PB with MapReduce. PB is not peanut-butter-and-jelly misspelled. It's 1 petabyte or 1000 terabytes or 1,000,000 gigabytes. It took six hours and two minutes to sort 1PB (10 trillion 100-byte records) on 4,000 computers and the results were replicated thrice on 48,000 disks. Update: Greg Linden points to a new Google article MapReduce: simplified data processing on large cluster

It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 server with SATA-II RAID and Infiniband HBA). Cluster file systems are still not mature for enterpr
