Quotas

VxFS supports quotas, which allocate per-user quotas and limit the use of two principal resources: files and data blocks. You can assign quotas for each of these resources. Each quota consists of two limits for each resource, the hard limit and soft limit.

The hard limit represents an absolute limit on data blocks or files. A user can never exceed the hard limit under any circumstances.

The soft limit is lower than the hard limit and can be exceeded for a limited amount of time. This allows users to exceed limits temporarily as long as they fall under those limits before the allotted time expires.

See Quota Limits for details on using VxFS quotas.
