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 and later—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 and later—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 and later—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 and later—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).

Storage Alert Threshold—Remaining disk space percentage that causes a storage alert to occur.

System Data Efficiency Ratio—Ratio that indicates the efficiency of compression, deduplication, RAID, and Thin Provisioning.

System RAID Overhead Ratio—The RAID overhead ratio for the entire system calculated using the RAID overhead from the existing storage types.

Estimated Usable Space—Calculation of the free space that is usable based on the current usage of the system.
