The 5 PB size is about quarter scale of the largest known Swift cluster. V.impressive. The 100 PB installation that RAX run consists of 6 federated clusters. Number of objects and request rate are unknown. 1000/42 comes comes to about 25-30 disks per server, but they mention 45-disk JBODs later, with plans to move to 90-disk JBODs. Nodes of large clusters continue getting fatter.
The cluster is in operation since 2011 (started with the Diablo release). They still use Pound for load-balancing.
