NOTE:
When enabling disk quotas on a volume, any users with write access to the volume who have not exceeded
their quota limit can store data on the volume. The first time a user writes data to a quota-enabled volume,
default values for disk space limit and warning level are automatically assigned by the quota system.
For more information about disk quotas, read the online help.
Adding storage
Expansion is the process of adding physical disks to an array that has already been configured.
Extension is the process of adding new storage space to an existing logical drive on the same array,
usually after the array has been expanded.
Storage growth may occur in three forms:
•
Extend unallocated space from the original logical disks or LUNs.
•
Alter LUNs to contain additional storage.
•
Add new LUNs to the system.
The additional space is then extended through a variety of means, depending on which type of disk
structure is in use.
NOTE:
This section addresses only single storage server node configurations. If your server has Windows Storage
Server 2003 R2 Enterprise Edition, see the Cluster Administration chapter for expanding and extending
storage in a cluster environment.
Expanding storage
Expansion is the process of adding physical disks to an array that has already been configured. The
logical drives (or volumes) that exist in the array before the expansion takes place are unchanged,
because only the amount of free space in the array changes. The expansion process is entirely
independent of the operating system.
NOTE:
See your storage array hardware user documentation for further details about expanding storage on the
array.
Extending storage using Windows Storage Utilities
Volume extension grows the storage space of a logical drive. During this process, the administrator
adds new storage space to an existing logical drive on the same array, usually after the array has
been expanded. An administrator may have gained this new storage space by either expansion or
by deleting another logical drive on the same array. Unlike drive expansion, the operating system
must be aware of changes to the logical drive size.
