The Storage Dashboard provides an at-a-glance view of storage resources in your CloudSoda environment. Read through the following topics to familiarize yourself with the dashboard's features, manage storage resources, and monitor their status.
Accessing the Dashboard
To access the Storage dashboard, click Orchestration > Storage in the left-hand navigation panel.
The Storage page displays. Storage resources can by displayed either in a list or gallery view by clicking one of the icons to the left of the search bar at the top of the page.
List View
The list view provides a high-level, compact view of all storage resources in your CloudSoda system. For each resource, the dashboard displays the storage name, storage type, access level (read & write), and storage capacity (used and available), along with color-indicated state of the resource. Clicking on a specific storage displays its key metrics and information, discussed below in Detailed View.
Gallery View
The gallery view presents storage resources in a card format, making it easier to visualize details about individual storages. The gallery format presents similar storage information to the list view - name, type, storage capacity (used and available), and status are show. Because of the card size, not as many storage resources are visible on-screen, but you can scroll down to see more. Clicking on a specific storage resource displays its key metrics and information, discussed in Detailed View.
Detailed View and Management Actions
Clicking on a specific storage opens a card showing additional details and relationships of the selected resource, organized across three tabs (Detail, Agents, and Scopes). From these tabs, storage-related management actions are available.
Details Tab
In the Details tab, data for the selected storage is shown in upper and lower panes. The resource name is listed in the upper pane, with icons and text indicating the storage type, in this example, file-based storage. The resource's storage capacity (used and available) are listed with the ring surrounding the storage icon showing the proportional capacity utilization. The number of agents attached to the storage are also listed.
The lower pane includes data on when the storage was created and updated, its location and associated price book, default Accessor, key, and storage class.
Agents Tab
The Agents tab displays details about Agents attached to the storage resource and their associated Accessors. For each Agent, its name, related Accessor, color-coded status is shown, with the total number of Agents in each state listed in the upper pane. The ring surrounding the storage icon shows the proportional distribution of the Agent states.
The graphic below shows a typical Agents tab, with one Agent (external agent 1) shown online. Its Accessor (LocalFile) is also listed. The state distribution ring appears solid green because only one Agent is attached to the storage and it is online. Several Agent-related management actions are available on this tab.
Attaching a New Agent
To attach a new Agent to the storage, click the Plus icon, select the Agent and the Accessor, and click the Checkmark icon to confirm. The storage card updates to list the new Agent and include it in the total number of connected agents.
Enabling, Disabling, and Deleting Agents
To enable an Agent and take it online, hover over the right side of the row where the Agent is listed and click the enable (>) icon. When the Agent goes online, its state changes to green (online).
To disable an online Agent, hover over the right side of the row listing the Agent and click the pause icon. When the Agent goes offline, its state changes to disabled (gray). If you want to take the Agent back online, click the enable (>) icon. If you want to delete the Agent, click the delete icon. If you delete the Agent, it will no longer be attached to the storage resource.
For all of these management actions, you have to refresh the detailed view of the storage resource for the Agent state changes to be reflected in the upper pane.
Agent States
Individual Agent states are enabled/online (green), disabled (gray) or broken (red). Enabling or disabling an Agent causes it to change state, with the Agent's current status indicated by color-coding: green when it's enabled and gray when it's disabled. An Agent is broken and displays a red state indicator when it cannot access the storage.
IMPORTANT: Keep in mind that an Agent's color-coded state indicator only shows the status of that specific component, not any other Agent or Accessor, nor the overall state of the attached Storage. This can be confusing because the Storage Dashboard's list view and the Details tab for individual resources also use color-coded indicators to show the Storage's global status - active (green) or inactive (gray). In the following example, the Storage resource Dell ECS (shown in the left graphic) is active and available in the CloudSoda environment. Dell ECS has one attached Agent, named external agent 1. Clicking the Agents tab to display details (shown in the right graphic), we see that external agent 1 is disabled (gray). This Agent's offline state only applies to this component and does not reflect the status of any other Agent or the Dell ECS storage resource.
Scopes Tab
The Scopes tab lists the scopes that include the selected Storage as an attached resource. The graphic below shows a typical Scopes tab listing the Default scope and one custom scope, All Resources. Several scope-related management actions are available on this tab.
Attaching Storage to a New Scope
To attach storage to a new scope, click the Plus icon, click the drop-down to select the scope, and click the Checkmark icon to confirm. The Scopes tab updates to list the selected scope. If you click the scope, its Resources tab displays and lists the newly-attached storage resource.
Removing Storage from an Existing Scope
To remove storage from an existing scope, so it is no longer an attached resource, hover over the right side of the row listing the scope and click the delete icon. The Scopes tab updates and no longer lists the scope.
