There's NO "underlying storage architecture", typically. Although you could
configure Swift that way, nobody sane does it for production. Any account/
container/object node has physical drives attached to it. In a way, Swift
constitutes its own storage architecture.

Rackspace run possibly the largest production cluster in the world.
It certainly is the oldest, anyway. According to Chuck's lecture at
the Icehouse Summit, they attach 90 3TB SATA drives to 1 object node,
for the total of about 85 PB. Easy division operation shows that they
have at least 314 object server nodes in 1 cluster.
