The Array Capacity and Utilization report provides an overview of storage array capacity and utilization. Use this report to identify storage arrays that are under utilized or highly utilized.

The Array Capacity & Utilization report represents Hitachi NAS (HNAS) arrays in the following manner:

Table: Array Capacity & Utilization (Hitachi NAS Arrays)

Column name	Description
Storage Array	The name of the Hitachi NAS (HNAS) array.
Model	The model of the storage array as assigned by the vendor. Use this name to ascertain the vendor's product specifications.
Status	The status of the array; for example, online or offline.
Product	The name of the product for this Hitachi NAS array. This field provides an indicator of capacity specifications, such as LUNs, hosts per array, and drives per array.
# Storage Servers	Click the value to view the HNAS Storage Server Summary. See Hitachi NAS Storage Server Summary.
# Storage Subsystems	Number of storage sub-systems associated with this array.
# EVS	Number of Enterprise Virtual Servers (EVS). See Hitachi NAS EVS Summary.
# 10G Ports	The number of 10G ports on all Enterprise Virtual Servers (EVS). See Hitachi NAS Ethernet Port Summary.
# Disks	Click the value to view the HNAS Disk Summary. See Hitachi NAS Disk Summary.
# CIFS Shares	Click the value to view the HNAS CIFS Share Summary. See Hitachi NAS CIFS Share Summary.
# NFS Shares	Click the value to view the HNAS NFS Export Summary. See Hitachi NAS NFS Export Summary.
# FTP Mounts	Sum of the FTP mount points.
# iSCSI LUNs	Sum of the iSCSI Block LUNs.
Physical Summary
Internal Capacity	The Hitachi NAS (HNAS) filer heads will not have any internal capacity, as they rely on block storage arrays.
External Capacity	Sum of the capacity of all block storage array LUNs being virtualized by the Hitachi NAS filer.
Allocated	Sum of the capacity of all the system drives allocated to Storage Pools.
Available	Sum of the capacity of all system drives not allocated to Storage Pools.
% Available	Expressed as a percentage, Available/Internal capacity.
Raw Usage	Expressed as a percentage, Allocated/Internal capacity.
Storage Pools Summary
# Storage Pools	Sum of the array's Storage Pools. See Hitachi NAS Storage Pool Summary.
Storage Pool Capacity	Sum the of array's Storage Pool capacity for File Systems (net RAID parity and overhead).
Storage Pool Used	Sum of the array's File System used capacity.
Storage Pool Available	The Storage Pool Capacity minus the Storage Pool Used.
File System Usage	Thermometer with a tooltip that displays % of Used/Capacity.
File System Summary
# File Systems	Number of array file systems. See Hitachi NAS File System Summary.
# Thin Prov File Systems	Number of file systems that are thin. See Hitachi NAS File System Summary.
File System Capacity	Sum of the array's file system sizes.
File System Used	Sum of the array's file systems' used capacity.
File System Available	File System Capacity minus File System Used
File System Usage	Percentage: Used/Capacity
LUN Summary
# LUNs	Number of iSCSI LUNs.
Total LUN Capacity	Sum of the array's iSCSI LUN sizes.
# Allocated LUNs	Sum of the array's iSCSI LUNs allocated to hosts.
Alloc LUN Capacity	Sum of the array's iSCSI LUNs allocated sizes.
# Unallocated LUNs	Sum of the array's iSCSI LUNs not allocated to hosts.
Unalloc LUN Capacity	Sum of the sizes of the array's iSCSI LUNs not allocated to hosts.
LUN Usage	The percentage of the LUN that is allocated, Capacity/Total Capacity.
