NOTE:
This section addresses only single storage system node configurations. If your server has Windows Storage Server 2008 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.
You extend a volume to:
•Increase raw data storage
•Improve performance by increasing the number of spindles in a logical drive volume
•Change
For more information about RAID levels, see the Smart Array Controller User Guide, or the document titled Assessing RAID ADG vs. RAID 5 vs. RAID 1+0. Both are available at the Smart Array controller web page or at http://h18000.www1.hp.com/products/servers/proliantstorage/arraycontrollers/ documentation.html.
Extend volumes using Disk Management
The Disk Management
NOTE:
Disk Management cannot be used to extend basic disk partitions.
Guidelines for extending a dynamic volume:
•Use the Disk Management utility.
•You can extend a volume only if it does not have a file system or if it is formatted NTFS.
•You cannot extend volumes formatted using FAT or FAT32.
