Monitoring Storage Space
Monitoring Storage Space
Storage Center sends an Alert when additional space is required. The Storage Center:
• Automatically monitors the amount of space used and the amount of space remaining
on a Storage Center, both as a percentage of space and an absolute value
• Automatically allocates disk space for volumes to use as needed
• Notifies you when remaining free space falls below the Storage Alert Threshold
Storage Center groups all disks in a managed Disk Folder into one common pool of
storage. Volumes draw space from the common pool. Each volume simultaneously uses all
of the disk drives in the shared storage pool for improved data access rates.
Figure 204. Shared Storage Pool
Note An exception to the efficient pool of storage is created when disks are assigned to a
second Managed Disk Folder or volumes are created with non-standard datapage
sizes or redundancy. To take full advantage of Dynamic Capacity, assign all disks to
one Managed Disk Folder using standard Storage Type volumes.
Space is allocated from the shared storage pool as new volumes are created, additional
data is stored on volumes, and Replays are taken and stored.
