Changes
added mentioning of S3
* No special hardware requirements. Commodity hardware (SATA/SAS drives, 1Gbit+ Ethernet) can be used to create a storage.
* Strong consistency semantics. This makes Pstorage suitable for iSCSI, VMs and CTs running on top of it (unlike object storage such as Amazon S3 or Swift).
* Usable for Containers or exportable as iSCSI, NFS, S3 object storage
* Built-in replication.
* Automatic disaster recovery on hard drive or node failures.
