Disk quotas are a file system feature that allows administrators to set limits on the amount of disk space that users or groups can consume. By configuring a hard quota, the system will prevent the user from writing any more data once their allocated disk space limit is reached, thereby enforcing the acceptable use policy.

Resource pools are used in virtualization environments to manage and allocate CPU and memory resources to groups of virtual machines, not to limit user disk space.

LUN masking is a storage area network (SAN) security feature that restricts which servers can access specific LUNs (Logical Unit Numbers), and it does not limit individual user disk space usage.

Reservations, typically used in virtualization or resource management, guarantee a minimum amount of resources (like CPU or memory) for a VM or application, rather than limiting disk space consumption.
