Status Information
The top portion of the Status plugin displays information about disk space usage.
NOTE: The information displayed varies with the Storage Center version.
Disk Space
• Disk—Total amount of raw disk space on all drives in the Storage Center.
• Spare—Amount of space distributed across all drives that is reserved for balancing drive usage and recovering from a drive failure.
For Storage Center version 7.3 and earlier, this value will appear as zero, because a hard drive is dedicated to spare space usage.
Available Space
• Available—Amount of space allocated for volumes on the Storage Center. Calculated as:
• Storage Center version 7.4.10—Used space + Free space
• Storage Center versions 7.3-7.4.2—Allocated + Free space
• Free—Amount of disk space available for use by a Storage Center. Calculated as:
• Storage Center version 7.4.10—Storage Type Free space + Disk Free space
• Storage Center versions 7.3-7.4.2—Free space = Disk Free space
• Used—Amount of configured space used by the Storage Center plus RAID overhead. The calculation includes used space on different
objects, depending on the Storage Center software version and the use of hot spares versus distributed spares:
• Version 7.4.10—sum of all used space for each Storage Type.
• Earlier versions—combination of the sum of used space on hot spares, distributed spares, and Storage Type, depending on the
system configuration.
Configured Space—Total amount of space available on all of the configured volumes in the Storage Center. Calculated as:
• Storage Center version 7.4.10—Configured space is equal Total space
• Storage Center version 7.2 and earlier, Configured space is equal to Available space
Allocated Space—Amount of disk space allocated on the disks for volumes plus RAID overhead. (Not used in Storage Center versions
7.1 or 7.2).
