| PackageDescription | distributed virtual object store - object-expirer
OpenStack Object Storage (code-named Swift) creates redundant, scalable object
storage using clusters of standardized servers to store petabytes of
accessible data. It is not a file system or real-time data storage system, but
rather a long-term storage system for a more permanent type of static data
that can be retrieved, leveraged, and then updated if necessary. Primary
examples of data that best fit this type of storage model are virtual machine
images, photo storage, email storage and backup archiving. Having no central
"brain" or master point of control provides greater scalability, redundancy
and permanence.
.
Objects are written to multiple hardware devices in the data center, with
the OpenStack software responsible for ensuring data replication and
integrity across the cluster. Storage clusters can 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 servers can be used in lieu of more
expensive equipment.
.
This package provides the swift object expirer daemon. Only a single instance
of this daemon is needed for a given swift cluster, which is why it is
packaged separately. |
