Sites

Monitor the capacity and space usage of the sites in IBM Cloud Object Storage. See which COS Slicestor and COS Accesser nodes are on each site and which sites are protected against COS Accesser node failures.

A site is the location, such as the geographical location or the building, of the nodes in the storage system. IBM Cloud Object Storage can be deployed on a single site or across multiple geographically dispersed locations based on your business requirements.
Additional information is provided about the following attributes of sites:
Accesser® Nodes
The number of COS Accesser nodes on the site.
Accessibility
The minimum number of COS Accesser nodes that can fail before one or more vaults become inaccessible from the site.

For example, a value of 5 indicates that all the vaults that are accessed from the site have at least five COS Accesser nodes available to read and write data. A value of 1 represents the highest risk because it indicates that if a COS Accesser node on the site fails, then one or more vaults cannot be accessed.

The following values might be shown:
Accessibility Description
0 All the vaults in the storage system are inaccessible from the site because no COS Accesser nodes are configured on the site.
Error status0 Some vaults are inaccessible from the site because the COS Accesser nodes that are configured to access the vaults from the site are not available.
1 All the vaults that are accessed from the site have at least one COS Accesser node available to read and write data.
Warning status1 All the vaults that are accessed from the site have at least one COS Accesser node available to read and write data. Some COS Accesser nodes that are configured on the site are not available.
Acknowledged
Shows whether a user marked the status of the site as acknowledged. An acknowledged status indicates that the status was reviewed and is either resolved or can be ignored.
Slicestor® Nodes
The number of COS Slicestor nodes on the site.
Status
The overall status of the site. This status represents the most critical status that is detected for the access pools or the storage pools that are associated with the site. The following examples show some of the conditions that determine the overall site status:
  • If one of the COS Slicestor nodes is not available, an error icon Error condition icon is shown.
  • If all of the COS Accesser nodes in an access pool are not available, an error icon Error condition icon is shown.
  • If all the COS Slicestor are available but some of the COS Accesser nodes are not available, a warning icon Warning status is shown.
