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

Use this report to identify storage arrays that are under-utilized or highly utilized.

Raw capacity is the summation of the physical disks. Usable space is the space that is calculated from RAID groups and LUNs.

This array information can be used to reference the array vendor's capacity limits.

Table: Array Capacity & Utilization - (EMC Symmetrix View)

Column name	Description
Storage Array	The name that you assigned to the array. Available values include all supported storage arrays.
Family	The family classification of the storage array as assigned by the vendor. Use this name to ascertain the vendor's product specifications.
Type	The specific model of the storage array.
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.
# FC Ports	Number of Fibre Channel ports. See Array FC Port Utilization .
# EF Ports	Number of EF - FICON (Fibre-ESCON) director ports.
# RA Ports	Number of RA - RDF director ports. Links to the RA Summary report.
# Hosts	This is the total number of unique hosts that have LUNs assigned by this storage array, and the hosts have been successfully queried using one or more host resource policies. If zero, host resources data has not been collected.
Host Usage	Amount of capacity used by hosts.
Physical Summary
Capacity	Sum of the capacity of all physical disks from all array groups, allocated, hot spares and unallocated.
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.
Hot Spares	Total capacity of hot spare drives.
Unallocated	Unallocated storage is storage that is not part of an Array Group
Raw Usage	Expressed as a percentage, total capacity of the LUNs in the array that have been assigned to a host and that are not available for provisioning.
Save Pools
# of Pools	Number of Save Pools for this storage array, representing the point-in-time copy of data
Pool Capacity	Total physical capacity for all the Save Pools associated with this array. Note that Save Pool capacity can make the Total FB LUN Capacity appear inflated or duplicated.
Pool Capacity Enabled	Amount of Save Pool capacity that has been enabled for host writes.
Pool Capacity Used	Amount of the Save Pool capacity that has already been consumed by hosts.
Pool Usage	Expressed as a percentage, this is the capacity of the Save Pools that has already been used by hosts.
Raw RAID Group Summary
# RAID Groups	The number of array groups in the storage array. See List Array Groups .
RAID Groups Capacity	Total capacity of the array groups in the storage array.
RAID Groups Used	Total used capacity of the array groups (by LUNs) in the storage array.
RAID Groups Available	Available capacity of the array groups in the storage array.
RAID Group Usage	Thermometer with a tooltip that displays the percentage used.
Thin Provisioning
# of SRPs	Links to the EMC Symmetrix SRP Summary for storage resource pool information.
# of Pools	Links to EMC Symmetrix Thin Pool Summary.
Pool Capacity	Total capacity of the thin pool.
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.
% Used	Pool used divided by pool capacity = % used.
Pool Subscribed	The physical capacity that has been given to hosts/applications; this is from the host's perspective.
% Subscribed	Amount of capacity that has been subscribed to users.
LUN Summary
# FB LUNs	Number of FB (fixed block) LUNs. See LUN Utilization Summary .
Total FB LUN Capacity	Total capacity of all the FB (fixed block) LUNs for this array. See the Save Pool section of this report to verify capacity values.
#Allocated FB LUNs	Links to the LUN Utilization Summary. See LUN Utilization Summary .
Alloc FB LUN Capacity	Total storage capacity for the FB (fixed block) LUNs.
# UnAllocated FB LUNs	The number of FB (fixed block) LUNs that have yet to be allocated. See LUN Utilization Summary .
UnAlloc FB LUN Capacity	Total unallocated capacity for FB (fixed block) LUNs.
FB LUN Usage	Mouse over the thermometer to view the percentage of the fixed block LUNs that are allocated.
# CKD LUNs	Total number of Count-Key-Data (CKD) LUNs.
CKD LUN Capacity	Total capacity of Count-Key-Data (CKD) LUNs.
# CKD Allocated LUNs	Total number of allocated Count-Key-Data (CKD) LUNs.
CKD Alloc LUN Capacity	Total allocated capacity of Count-Key-Data (CKD) LUNs.
# CKD UnAllocated LUNs	Total number of unallocated Count-Key-Data (CKD) LUNs.
CKD UnAlloc LUN Capacity	Total capacity of unallocated Count-Key-Data (CKD) LUNs.
CKD LUN Usage	Mouse over the thermometer to view the percentage of the Count-Key-Data (CKD) LUNs that are allocated.
