Table: Array Capacity & Utilization - (EMC VNX Celerra View)
Column name | Description |
|---|---|
|
Storage Array |
The name that you assigned to the array. Available values include all supported storage arrays. |

The family classification of the storage array as assigned by the vendor. Use this name to ascertain the vendor's product specifications. |
|
Vendor |
The name of the vendor that distributes the storage array. |
|
Product |
The name of the product, typically shown as a series number. This field provides an indicator of capacity specifications, such as LUNs, hosts per array, and drives per array. |
|
Version |
Version of the storage array software. |
|
Status |
Status of the array. |
|
# DMs |
Number of Data Movers links to the Data Mover report where you can chart CPU and Memory utilization. |
|
# VDMs |
Number of Virtual Data Movers links to the Virtual Data Mover report. |
|
# FC Ports |
Number of storage director Fibre Channel ports. |
|

|
Physical Summary | |
|
Capacity |
Sum of the capacity of all physical disks from all array groups, including spares (drives that are not allocated to an array group). |
|
Allocated |
Allocated storage is physical storage consumed, including parity overhead and system overhead. A gap between raw and allocated capacity may indicate unused capacity, such as drives in a rack that are not in use. |
|
Available |
Total raw capacity of the array that has not been allocated. The size is displayed in the units you selected with the Advanced option when you generated the report. |
|
% Available |
% of storage that is available. |
|
Raw Usage |
% indicates raw usage. |
|
Raw RAID Group Summary | |
|
# RAID Groups |
Number of raw RAID groups for this storage array. |
|
RAID Groups Capacity |
Amount of capacity associated with the array's RAID groups. |
|
RAID Groups Used |
Amount of raw RAID group capacity that is currently in use. |
|
RAID Groups Available |
Amount of raw RAID group capacity that is available. |
|
RAID Group Usage |
% of the RAID group capacity that is in use. |
|
Storage Pools | |
|
# Storage Pools |
Number of storage pools for this array; links to the Storage Pools Summary report. |
|
Raw Capacity |
The storage pool's raw capacity. Raw capacity is the summation of the physical disks. |
|
Used Capacity |
The amount of storage pool capacity that is in use. |
|
Available Capacity |
The amount of storage pool capacity that is available. |
|
Potential Capacity |
Storage pool capacity, including available space that can be allocated (depending on the associated storage profile). |
|
Thin Pool Total |
Total of thin pool capacity for the storage pools. |
|
Thin Pool Used |
Amount of thin pool capacity in the storage pools that is in use, not including LUNs that have not yet been physically allocated. |
|
Thin Pool Available |
Amount of thin pool capacity in the storage pools that is available. |
|
% Subscribed |
% of the thin pool capacity that is subscribed. |
|
Volume Summary | |
|
# Disk Vols |

|
# Slice Vols |
Number of slices within the volumes. |
|
# Stripe Vols |
Number of strip volumes configured to improve performance. |
|
# Meta Vols |

|
# Pool Vols |
Number of pool volumes, used to store Celerra SnapSure checkpoint data (SavVol) or Celerra Replicator copies (ConfigVol). |
|
Volume Capacity |
The amount of capacity associated with all the volumes. |
|
# Allocated Vols |
Number of volumes allocated to Celerra file systems. |
|
Allocated Vol Capacity |
Amount of capacity associated with the allocated volumes. |
|
# Unallocated Vols |
Number of volumes that have not been allocated to Celerra file systems. |
|
UnAlloc Vol Capacity |
Amount of capacity associated with the unallocated volumes. |
|
Vol Usage |
% of the volumes that is in use. |
