Physical Summary | |
# Pools | Links to XIV Storage Pools Summary |
Soft Limit | The logical amount of space for all storage pools in the array. A soft limit greater than the hard limit indicates thin provisioning. |
Hard Limit | Maximum physical capacity that can be used by volumes and snapshots in the pool. |
Free Hard | Amount of unused physical space in the array |
Free Soft | Unused amount of the logical storage that has been presented to hosts and applications |
Hard Utilization | (hard limit - free hard)/hard limit |
Spare Disks | # of spare disks in the array |
Spare Modules | # of spare modules in the array |
Target Spare Disks | # of spare disks on the remote target system |
Target Spare Modules | # of spare modules on the remote target system |
Usable Summary | |
Disk Space | Sum of the number of drives times the drive capacity |
Available Disk Space | XIV Available Disk Space = (number_of_disks - number_of_spare_disks - (number_of_spare_modules * 12) * disk_capacity * 0.96/2 |
Formatted Volume Space | Sum of all volume sizes, or total allocated (or provisioned) storage |
Formatted Snapshot Space | Sum of volume sizes minus the sum of all volumes used |
Formatted Space | Formatted available and usable storage |
Formatted Space Used | The Formatted Space Used value is used to derive Formatted Utilization |
Formatted with No Volumes | The unused portion of the provisioned capacity shared by all volumes; volumes do not consume storage until pages are written by the OS; all LUNs are thin |
Overall Unavailable Disk Space | Metadata and system reserve used for traces and statistics |
Subscription | The thermometer mouse-over indicates if storage has been over-subscribed. |
Formatted Utilization | The thermometer mouse-over indicates the formatted storage utilization %, calculated as Formatted Space Used/Formatted Space |
