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. |
Last Poll Time | Indicates the last time the data was collected from the storage array and persisted to the Portal database. |
# Ports | The number of ports in the array. Click the value to view the Array Port Utilization. |
# 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. Click the value to go to the
Host Capacity & Utilization. |
# Disks | The number of physical disks for this storage array. |
Host Usage | Links to the
LUN Utilization Summary. |
Physical Summary | |
Capacity | For EMC CLARiiON arrays: Sum of the capacity of all physical disks from all array groups—including spares (drives that are not allocated to an array group). |
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
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. Click the link to view the
LUN Utilization Summary. |
Total LUN Capacity | The total capacity for the 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. storage array --> array port --> host storage domain --> HBA port --> host. Click the link to view the
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). |
Thin Provisioning | |
# of Pools | Number of thin pools. Drills down to the relevant Thin Pool Summary report. |
Raw Capacity | The raw capacity of the pool. Raw capacity is the summation of the physical disks. |
User Capacity | The physical capacity that’s available to all LUNs in the storage pool; also known as usable capacity or host-visible capacity. |
Consumed Capacity | The physical capacity that is assigned to all LUNs in the storage pool. From the array’s perspective, consumed capacity is the same as allocated capacity. |
% Used | Consumed Capacity divided by User Capacity |
Available Capacity | The physical pool storage that is not allocated to pool LUNs |
Subscribed Capacity | The physical capacity that has been given to hosts/applications; this is from the host’s perspective |
% Oversubscribed | Oversubscribed capacity refers to Subscribed Capacity that exceeds User Capacity. |
