The Array Capacity & 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 Vantara All-Flash and Hybrid Flash Storage in the following manner:
Table: Array Capacity & Utilization (Hitachi Vantara All-Flash and Hybrid Flash Storage view)
Column name | Description |
|---|---|
Array/Cluster Summary | |
|
Array Name |
The name that you assigned to the array. Available values include all supported storage devices. For a list of supported devices, see the Certified Configurations Guide. |
Serial #: | Serial number of the cluster. |
IP Address | IP address of the flash storage. |
Model | 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 | The date and time of the last successful data collection cycle. |
Firmware Version | Current firmware version of the array. |
# FC Ports | The number of FC ports in the array. Click the value to view the Array Port Utilization. |
# iSCSI Ports | Number of iSCSI ports. Click the link to drill down to the Array iSCSI Port Utilization report. |
# Disks | The number of disks in the array. Click the value to view the Disk 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. |
Cache | Cache size of the array. Values are stored as TiB in the database and rendered according to your user profile preferences. |
Host Usage | Links to the LUN Utilization Summary. See LUN Utilization Summary . |
|
Physical Summary | |
|
Raw Capacity |
For HDS arrays: Sum of capacity of all PDEVs from all array groups. When calculating raw capacity for HDS arrays, the data collector makes requests to the Device Manager for physical devices (PDEVs) for all Array Groups in a storage array. The data collector assumes that all PDEVs are part of an array group, so PDEVs that are marked as not included in an array group (-1) are included in the capacity calculation. That is, no disks are treated as spares. |
Allocated | Total of all of disk capacities (physical storage). |
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. |
|
# Array Groups | Number of Array Groups. Links to List Array Groups report. |
|
Pool Summary | |
|
# Pools |
The number of dynamic provisioning pools links to the Dynamic Provisioning Pool Summary |
|
Total Capacity | The total capacity for the volumes/LUNs. |
|
Used Capacity |
Amount of internal RAID group capacity allocated to LUNs. |
|
Available Capacity |
Amount of available capacity in RAID groups from which to allocate LUNs. |
# Resv Vols/LUNs | The number of LUNs that are reserved on the array. Click the link to view the LUN Utilization Summary. |
|
# Resv Vols/LUN Capacity |
Capacity of the reserved LUNs that cannot be assigned to the hosts. For example, dynamic pool capacity. |
Volume/LUN Summary | |
# Vols/LUNs | The number of LUNs that have been created on the array. Click the link to view the LUN Utilization Summary. |
Total Vol/LUN Capacity | The total capacity for the volumes/LUNs. |
# Allocated Vols/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. Click the link to view the LUN Summary. |
Alloc Vol/LUN Capacity | The total storage capacity for the allocated LUNs. |
# UnAllocated Vols/LUNs | The number of LUNs that have yet to be allocated. Click the link to view the LUN Summary. |
UnAlloc Vol/LUN Capacity | The available LUN capacity. |
