Hosts to Volumes page in the Hosts view
The Hosts to Volumes page in the Hosts view enables you to get more information about the volume mapped to a specific host and more especially:
- the name of the volume
- the name and type of storage pool attached to the volume
- the RAID level used
- the capacity exposed to the host and consumed by the host.
To access the page, in the Helix Continuous Optimization Dashboard, click Capacity > Storage > Hosts, and in the Hosts view page, click the Hosts to Volumes 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 Volumes Mapping Table 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 Volumes Mapping Table |
| Storage System | Name of the storage system. | Not applicable | SA_CONTAINS_VOLUME |
| Vendor | System vendor. | Not applicable | ST_SYSTEM_VENDOR |
| RAID Level | RAID level of the volume (if available). | Not applicable | ST_VOLUME_RAID_LEVEL when available |
| Storage Pool | Name of the storage pool associated to the volume. | Not applicable | SP_CONTAINS_VOLUME |
| Pool Type | Type of the storage pool associated to the volume. | Not applicable | ST_POOL_TYPE |
| Pool Service Level | Level of service required. This information is not collected by the storage connectors but specified by the Administrator from the Workspace or a dedicated ETL. | Not applicable | ST_POOL_SERVICE_LEVEL |
| Volume Tiering Policy | Tiering policy applied to the volume. | Not applicable | ST_TIERING_POLICY |
| Storage Volume | Name of the volume. | Not applicable | NAME |
| Consumed Capacity [GB] | Capacity actually consumed in Gigabytes. | Average on the latest day | Sum of BYHOST_SIZE for the volumes that share the same Host |
| Host Visible Capacity [GB] | Amount of capacity exposed to the host (i.e. subscribed capacity) in Gigabytes. | Not applicable | Sum of BYHOST_ALLOCATED for the volumes 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.
