<title>Introduction to Object Storage</title>
|
|
<para>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 servers can be
|
|
used in lieu of more expensive equipment.</para>
|
|
<para>Object Storage is ideal for cost effective, scale-out
|
|
storage. It provides a fully distributed, API-accessible
|
|
storage platform that can be integrated directly into
|
|
applications or used for backup, archiving and data retention.
|
|
Block Storage allows block devices to be exposed and connected
|
|
to compute instances for expanded storage, better performance
|
|
and integration with enterprise storage platforms, such as
|
|
NetApp, Nexenta and SolidFire.</para>
