High scalability

By leveraging allocation groups, XFS provides excellent scalability.

The block device that supports the XFS filesystem is split into eight or more linear regions that are all the same size at the moment the filesystem is created. They are referred to as allocation groups. Each allocation group controls its own free disk space and inodes. The kernel can address multiple allocation groups at once since they are relatively independent of one another. The high scalability of XFS is made possible by this feature. These autonomous allocation groups naturally meet the requirements of multiprocessor systems.
