Hosts page in the Hosts view
The Hosts page in the Hosts view enables you to:
- know how many storage systems, storage pools, and volumes are attached to each host
- verify the capacity initially allocated and actually consumed by each host.
To access the page, in the Helix Continuous Optimization Dashboard, click Capacity > Storage > Hosts, and in the Hosts view page, click the Hosts tab.
Metrics per host are displayed in a tabular format.
By default, some columns are hidden. You can show or hide columns using the action menu
that is located next to the table title.
Each row in the table represents a host and displays the following metrics, which are computed from the Hosts to Systems page.
Host-related metrics are not available when the option Disabled and Collected for metric computation (Default) are selected in the ETL additional settings. Refer to Customizing Volumes and Shares Monitoring for more information.
Column | Description | Statistical Type | Metrics |
|---|---|---|---|
Host | Name of the host. Depending on the information available, the value will either be the entity name, the collected host name or the collected WWN or IQN. | Not applicable | Grouping criteria from Hosts to Systems |
| Number of Storage Systems | Number of storage systems mapped to the host. | Not applicable | Count of Storage Systems that share the same hostname |
| Number of Storage Pools | Number of storage pools of the storage system that are actually mapped to the host. | Not applicable | Count of Storage Pools that share the same hostname |
| Number of Storage Volumes | Number of volumes of the storage system that are actually mapped to the host. | Not applicable | Count of Storage Volumes that share the same hostname |
| Consumed Capacity [GB] | Capacity actually consumed in Gigabytes. | Average on the latest day | Sum of BYHOST_SIZE for the volumes that share the same hostname |
| Host Visible Capacity [GB] | Amount of capacity exposed to the host (i.e. subscribed capacity) in Gigabytes. | Average on the latest day | Sum of BYHOST_ALLOCATED for the volumes that share the same hostname |
To find a specific host
Use the sorting and filtering options on the page to find a specific host. For more information, see Using Filtering Options in Helix Capacity Optimization Dashboard.
