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.
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. Links to the Array FC Port Utilization report.
# 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. Links to 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. Links to the 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, which displays the allocated LUNs.
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. Links to the LUN Utilization Summary, filtered by unallocated LUNs.
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.
