Кстати, посмотри на OpenStack, в частности, Swift (object storage). Интерес в OpenStack сейчас очень высокий, и куча толстых вендоров вливает в разработку его компонентов (всё - опенсурц) очень много ресурсов.
Вот OpenStack Beginner's guide, для краткого ознакомления:
"Swift provides a distributed, eventually consistent virtual object store for OpenStack. It is analogous to Amazon Web Services - Simple Storage Service (S3). Swift is capable of storing billions of objects distributed across nodes. Swift has built-in redundancy and failover management and is capable of archiving and media streaming. It is extremely scalable in terms of both size (Several petabytes) and capacity (Number of objects)."
