Introducing HP Storage Manager 60 Volume Volume Group Free Capacity Unconfigured Capacity A logical object that is the basic structure created on the Storage Array to store data. One or more volumes are configured across a volume group, and each volume is seen by the operating system as one drive. A set of drives that are logically grouped together by the controllers in a Storage Array. Each volume group is assigned an appropriate RAID level to meet application needs for data availability and I/O performance. The RAID level is a volume group parameter, not a volume parameter. A contiguous region of unassigned capacity on a designated volume group. The space can be used to create one or more volumes. Note: In the Array Management Window Logical View, free capacity is shown as Free Capacity Nodes. Multiple Free Capacity nodes can exist on a volume group. Capacity present in the Storage Array from drives that have not been assigned to a volume group. The space can be used to create new volume groups. Note: In the Array Management Window Logical View, unconfigured capacity is shown as an Unconfigured Capacity Node. 8 INTRODUCING HP STORAGE MANAGER 60

Volume
A logical object that is the basic structure created on the Storage Array to store data.
One or more volumes are configured across a volume group, and each volume is seen
by the operating system as one drive.
Volume Group
A set of drives that are logically grouped together by the controllers in a Storage Array.
Each volume group is assigned an appropriate RAID level to meet application needs
for data availability and I/O performance. The RAID level is a volume group
parameter, not a volume parameter.
Free Capacity
A contiguous region of unassigned capacity on a designated volume group. The space
can be used to create one or more volumes.
Note:
In the Array Management Window Logical View, free capacity is shown as Free
Capacity Nodes. Multiple Free Capacity nodes can exist on a volume group.
Unconfigured Capacity
Capacity present in the Storage Array from drives that have not been assigned to a
volume group. The space can be used to create new volume groups.
Note:
In the Array Management Window Logical View, unconfigured capacity is shown
as an Unconfigured Capacity Node.
