I believe the only reference to "Cactus" in the Object Storage Admin
Guide is that Glance has been stable since Cactus. Please re-read the
sections starting here:
For folsom: http://docs.openstack.org/trunk/openstack-object-storage/admin/content/logical-architecture.html

For essex: http://docs.openstack.org/essex/openstack-object-storage/admin/content/logical-architecture.html

Object Storage is Swift, Block storage is Cinder as of the Folsom
release. Please read:
http://docs.openstack.org/trunk/openstack-object-storage/admin/content/overview-block-storage-arch.html

We don't yet have a separate "Block Storage" Admin guide to point to.

Hope this helps.
