"calls. Each Nova service, such as Compute, Scheduler, and so on, creates two"

"OpenStack Object Storage (code-named Swift) is open source software for "
"creating redundant, scalable data storage using clusters of standardized "
"servers to store petabytes of accessible data. It is a long-term storage "
"system for large amounts of static data that can be retrieved, leveraged, "
"and updated. Object Storage uses a distributed architecture with no central "
"point of control, providing greater scalability, redundancy and permanence. "
"Objects are written to multiple hardware devices, with the OpenStack "
"software responsible for ensuring data replication and integrity across the "
"cluster. Storage clusters scale horizontally by adding new nodes. Should a "
"node fail, OpenStack works to replicate its content from other active nodes."
" Because OpenStack uses software logic to ensure data replication and "
"distribution across different devices, inexpensive commodity hard drives and"

"_GettingTheCode: http://wiki.openstack.org/GettingTheCode Following these "

"able to run cinder (i.e., launch VM instances), you will also need to "
"install libvirt and at least one of the `supported hypervisors`_. Running "
"cinder is currently only supported on Linux, although you can run the unit "
"tests on Mac OS X. See :doc:`../quickstart` for how to get a working version"
