The Storage page displays counts of active, inactive, and unverified storage components, the total count of active objects, and information about system-wide total, used, and estimated available storage capacity. The page also displays information about individual storage components and their current capacity.

The Storage page displays several areas of information.

System-wide information

The top area of the page displays the following rolled-up information for HCP S Series Node storage components configured in the system.

Screenshot of top area of Storage page, which shows rolled-up information for HCP S Series Node storage components
  • Total capacity - the total number of bytes available, as well as the change over the past week
  • Used capacity - the total number of bytes used, as well as the change over the past week
  • Estimated available capacity - the total number of bytes unused, as well as the change over the past week
  • Total objects - the total count of objects stored across all storage components, as well as the change over the past week
  • Active storage - the number of storage components that can receive objects
  • Inactive storage - the number of storage components that cannot receive objects
  • Unverified storage - the number of storage components whose state can't be determined

The calculation of used capacity includes:

  • HCP S Series Node storage components configured for capacity monitoring
  • Storage components set to read-only status
  • Storage components that are inactive

Metrics for capacity usage are for Metadata Gateway instances only, so adding used capacity to estimated available capacity will not equal the total capacity on the system. Also, multiple services are running on a system instance, all sharing the disk capacity. Therefore, the estimated available capacity for the Metadata Gateway service on one node can be consumed by a different service running on the same node.

Note: If the MAPI Gateway service restarts, capacity values are shown as 0 until fresh metrics are obtained.

The calculation of estimated available system capacity does not include:

  • HCP S Series Node storage components not configured for capacity monitoring
  • Storage components other than HCP S Series Node storage components
  • Storage components set to read-only status
  • Storage components that are inactive

Per-storage component information

The central area of the page displays information for each HCP S Series Node storage component configured for capacity monitoring in the system.

Screenshot of central portion of Storage page, which lists information about each storage component
  • User-defined name.
  • Type (HCP S Series Node, displayed as HCPS_S3).
  • AWS region.
  • State:
    • Active - Available to serve requests
    • Inactive - Not available to serve requests (access is administratively paused)
    • Unverified - Not available to serve requests (unreachable by specified parameters, or awaiting administrative activation)
  • Whether or not the storage component is set to read-only status.
  • Disk capacity: A graphical display of used capacity as a percentage of total capacity. You can configure a warning threshold, which is displayed as a red line. If the used capacity is below the threshold the bar is displayed in blue, and if the used capacity exceeds the threshold the bar is displayed in red. If no capacity is used the bar is displayed in gray. For example:

    Example of disk capacity information for two storage components, displayed as bars with used capacity as a percentage of the total. One bar represents a storage component that is below the user-defined capacity threshold; the bar is displayed in blue. The other bar represents a storage component that has exceeded the threshold; the bar is displayed in red.

  • Total capacity (used plus free).
  • Available (estimated) capacity.

Capacity alerts are generated by the MAPI Gateway service. Use the System Management application to configure the capacity alert threshold for individual storage components or the overall system.

A more button (The More menu appears as three dots arranged vertically), to the right of each storage component, opens a menu of actions that you can perform on that storage component:
  • Edit - edit the configuration of the storage component
  • Set inactive | Set active- change the state of the storage component between active and inactive
  • Set read-only | Set read-write - change the status of the storage component between read-only and read-write

Active object information

The bottom area of the page displays a graph over time of the count of active objects stored in the system. The maximum time period is the previous week.
