Storage Pools
View information about the storage pools in object storage systems.
A storage pool is a logical collection of COS Slicestor nodes that is used to store vault data
in IBM
Cloud Object Storage.
Use the information on the Storage Pools page to complete the following
monitoring tasks:
- View the different sites that the COS Slicestor nodes in a pool are distributed to and view the number of nodes at each site.
- Monitor the used and available raw storage space on the Slicestor®.
- View the number of vaults that depend on each of the storage pools.
Tip: In the manager applications for IBM
Cloud Object Storage, storage capacity is represented in
decimal (base 10) units, such as kilobyte (KB), megabyte (MB), and gigabyte (GB). In
IBM Storage
Insights Pro,
storage capacity is represented in binary (base 2) units such as kibibyte (KiB), mebibyte (MiB), and
gibibyte (GiB). For more information, see Units of measurement for storage data.
Additional information is provided
about the following attributes of storage pools:
- Acknowledged
- Shows whether a user marked the status of a storage pool as acknowledged. An acknowledged status indicates that the status was reviewed and is either resolved or can be ignored.
- Sets
- The number of device sets in the storage pool and the number of COS Slicestor nodes in each of the device sets. For example, a value of 3(6) indicates that the storage pool has three device sets, with six nodes in each set.
- Site
- The location, such as the geographical location or the building, of the COS Slicestor nodes in the storage pool. To ensure
high availability for the vault data in IBM
Cloud Object Storage, you can distribute the nodes to
multiple sites.
The number of site columns that are shown depends on the number of sites that the COS Slicestor nodes are distributed to. For example, if the nodes in the storage pool are distributed to four sites, then four site columns will be shown. For each site, the number of nodes that are distributed to that site is shown.
- Status
- The status of the storage pool. Use the status to determine the condition of the storage pool,
and if any actions must be taken.
A Warning status is shown when one or more of the sites that is associated with the storage pool is unavailable. An Error status is shown when all the sites are unavailable. To ensure high availability for the vault data in IBM Cloud Object Storage, take immediate action to resolve site failures.
- Storage Risk
- The number of COS Slicestor nodes that can fail before one or more vaults in the storage pool become unavailable. The number of COS Slicestor nodes that can fail before read and write operations cannot be completed on one or more vaults in the storage pool. The status of the Slicestor nodes is determined by the health of the disk drives in the Slicestor node.
- Vaults
- The number of vaults that store data on COS Slicestor nodes in the storage pool.
Multiple vaults can be created on a single storage pool.
