Table: Array Capacity & Utilization - (Dell Compellent View)
Column name | Description |
|---|---|
|
Storage Array |
The name that you assigned to the array. Available values include all supported storage arrays/clusters. |
|
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. |
|
# 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. |
|
# Ports |
The number of ports in the array. Click the value to view the Array Port Utilization. |
|
Host Usage |
Links to the LUN Utilization Summary. See LUN Utilization Summary . |
|
Physical Summary | |
|
Capacity |
Total raw or physical capacity. |
|
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. |
|
Available |
Total raw capacity of the array that has not been allocated. The size is displayed in the units you selected with the Advanced option when you generated the report. |
|
% Available |
Expressed as a percentage, total capacity of the LUNs in the array that have not been assigned to a host and that are available for provisioning. This percentage is a better capacity indicator than the number shown as Available Size. |
|
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. |
|
Raw RAID Group Summary | |
|
# RAID Groups |
The number of array groups in the storage array. Links to the List Array Groups. 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. |
|
LUN Summary | |
|
# LUNs |
The number of LUNs that have been created on the array. See LUN Utilization Summary . |
|
Total LUN Capacity |
The total capacity for the volumes/LUNs. |
|
# Allocated LUNs |
The number of volumes/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. See LUN Utilization Summary . |
|
Allocated 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 |
Thermometer with a tooltip that displays the percentage allocated, calculated as Allocated divided by (Allocated + Unallocated). |
