Array Capacity and Utilization (NetApp Cluster)
To access this report, in the Navigation pane select:
Because NetApp Cluster mode uses a number of unique constructs—such as Aggregates and Volumes—to organize and access its storage, additional data is available through drilldowns.
The report is organized into four sections:
1. NetApp Cluster Summary
2. Physical Summary
3. Aggregate Summary
4. Volume Capacity
5. LUN Summary
6. Performance
NetApp Cluster Summary
This section of the report provides a overview of the storage system, with links to relevant components.
Cluster
NetApp Cluster name.
Last Poll Time
Date/Time of the last successful or partially successful collection cycle.
UUID
Product designator of NetApp instance (universally unique identifier).
SN
Serial number of the storage array.
ONTAP Ver
Version of ONTAP as of the last data collection.
Location
User designated. Free-form field describing the relative location of the cluster in the user’s environment.
Peer
Peer cluster name.
Contact
Primary contact information for the cluster.
# Nodes
Number of configured nodes in the cluster. Drill down to the NetApp Cluster-Mode Node Summary.
# Vservers
Number of configured Vservers. Drill down to the Vserver Summary report.
# FC Ports
Sum of all member nodes’ FC ports. Drill down to the Array Port Utilization reports for these ports.
# iSCSI Ports
Sum of all member nodes’ iSCSI ports. Drill down to the NetApp LUN Utilization Summary.
# CIFS Shares
Sum of all member nodes’ CIFS shares. Drill down to the NetApp CIFS report.
# NFS Exports
Sum of all member nodes’ NFS exports. Drill down to the NetApp NFS report.
# Disks
Sum of all member nodes’ disks. Drill down to the NetApp Disk Summary report for these disks.
# Hosts
Total number of connected hosts via all configured nodes. Drill down to the Host Capacity and Utilization report for these hosts.
Host Usage
Amount of logical capacity associated with host connections. Drill down to LUN Utilization Summary for these LUNs.
% Used
Percentage of used capacity associated with LUNs allocated to hosts.
 
Physical Summary
This section of information summarizes capacity and usage. The percentages, in particular, capture the essence of your current utilization status.
Internal Capacity
Sum of all disk drive capacities associated with individual member nodes.
External Capacity
For V-Series only, sum of all the usable capacities of volumes served up by external arrays associated with the V-Series array.
Virtualized Capacity
0, Cluster-mode does not virtualize capacity.
Allocated
Sum of all member nodes’ configured RAID Group capacities in the cluster.
Available
Represents the physical capacity of the Cluster that potentially could be provisioned in to RAID Groups. Could include customer designated spares. Calculated by subtracting Allocated capacity from Internal Capacity.
% Available
Percentage of Available Capacity relative to Internal Capacity (not External).
Raw Usage
Progress bar representing provisioned RAID Groups (including RAID overhead) relative to Internal Capacity.
Aggregate Summary
This section provides an overview of the aggregate and volume capacity and utilization.
# Aggregates
Number of member nodes' aggregates. Drill down to NetApp Aggregate Summary for these aggregates.
Aggr Capacity
The aggregate’s total size.
Aggr Used
Amount of the aggregate’s capacity in use.
Aggr Available
Available storage in the aggregate.
Aggr Usage
Used data storage at the physical layer. Mouse over the thermometer bar to view the % available.
Volume Capacity
This section provides an overview of the volume capacity and utilization.
# of Total Vol(ume)s
Sum of all member nodes’ volumes. Drill down to NetApp Volume Summary for these volumes.
# FlexVols
Sum of all member nodes’ thinly provisioned volumes (FlexVols). Drill down to NetApp Volume Summary for these volumes.
# Inf Vol(ume)s
Sum of all member nodes’ infinite volumes. Drill down to NetApp Volume Summary for these volumes.
# Thin Vol(ume)s
Sum of all member nodes’ volumes with Space Guarantee of none. Drill down to the NetApp Volume Summary for these volumes.
Vol(ume) Capacity
Used data storage at the physical layer. Mouse over the thermometer bar to view the percent available.
Vol(ume) Used
Total of used space for all the associated volumes.
Vol(ume) Available
Available capacity from all of the associated volumes.
Vol(ume) Usage
Used data storage at the logical layer. Mouse over the thermometer bar to view the percent available.
LUN Summary
The LUN fields enable drill-down access to additional details so that you can determine the capacity of each configured LUN.
# LUNs
Sum of member nodes’ FC and iSCSI LUNs. Drill down to LUN Utilization Summary for these LUNs.
Total LUN Capacity
Total storage capacity for all of the associated LUNs.
# Allocated LUNs
The number of LUNs on the array that have been mapped to a host. These LUNs are typically configured as volumes on the host and dedicated to an application. Drill down to LUN Utilization Summary for these LUNs.
Alloc LUN Capacity
The total storage capacity for the allocated LUNs.
# UnAllocated LUNs
The number of LUNs that have yet to be allocated.
UnAllocated LUN Capacity
The available LUN capacity.
LUN Usage
% of LUN capacity that is currently in use.
