To create zone, grouping of storage resources such as rack or storage node is done. Zones: Unser Regions come zones, which defines availability level that swift provides. Swift to support the read/write function, it favor the data that are closer to read and while write, data is written locally and then is transferred to rest of regions. Region: As Swift is a geographically distributed environment, data can be sent to multiple nodes that are placed in to different regions. Swifts isolates failures, and to achieve this, swift defines the new hierarchy that helps abstract the logical organization of data from physical one. Once data is written it si spread across other two redundant replicas. These metadata are stored with object itself in key/value pairs.īy default, a swift cluster storage has design considers the replica if three. In swift object storage solution, when we need to search, retrieve and index any data on object storage device, Meta data is used. This server defines where and how actual data and its metadata are stored and every object belongs to a container.
