Array Capacity and Utilization (NetApp Cluster)

To access this report, in the Navigation pane select:

Capacity Manager > Array Capacity & Utilization > Array Capacity & Utilization

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

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.

CPU Busy	Percentage of time one or more processors is busy in the system from last data collection cycle.
Sys Read Resp Time (ms)	System Read Response Time: Average response time for the Cluster in aggregate as of the last data collection poll. Includes all active Node read operations.
Sys Write Resp Time (ms)	System Write Response Time: Average response time for the Cluster in aggregate as of the last data collection poll. Includes all active Node write operations.
Read OPS	Read operations per second from the last data collection cycle.
