Hosts to Systems page in the Hosts view
The Hosts to Systems page in the Hosts view enables you to get more information about the storage system mapped to a specific host and more especially:
- the storage system name
- the number of storage pools and volumes attached to the host
- how much capacity is exposed to each host
- how much capacity is actually consumed.
To access the page, in the Helix Continuous Optimization Dashboard, click Capacity > Storage > Hosts, and in the Hosts view page, click the Hosts to Systems 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 Pools
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 Pools |
| Storage System | Name of the storage system mapped to the host. | Not applicable | NAME |
| Vendor | System vendor. | Not applicable | ST_SYSTEM_VENDOR |
| Number of Pools | Number of storage pools of the storage system that are actually mapped to the host. | Not applicable | Count of storage pools for the Storage System that have the same Hostname |
| Number of Volumes | Number of volumes of the storage system that are actually mapped to the host. | Not applicable | Count of volumes for the Storage System that have the same Hostname |
| Consumed Capacity [GB] | Capacity actually consumed in Gigabytes. | Average on the latest day | Sum of BYHOST_SIZE for the storage systems that share the same Host |
| 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 storage systems that share the same Host |
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.
