Configuring Data Foundation local storage

From the Data Foundation user interface page, you can configure local storage for IBM Storage Fusion Data Foundation.

Before you begin

Install service with device type as local.

Procedure

  1. Go to the Data Foundation page.
  2. Wait for the discovery of compute nodes to complete.
    After the discovery process completes, the Configure storage button is enabled.
  3. Click Configure storage.
  4. If you want to change the default disk size for your storage configuration, select from the available disk size and type in the Configure storage page. The type can be HDD or SSD/NVMe. If you have either SSD or HDD types available, then this option is not available for selection. The SSD/NVMe is the recommended option for optimal performance and reliability. The HDDs are supported for development or test only.
  5. In the Storage nodes section, select nodes from the node table based on the recommendation. They are candidate nodes to be selected as IBM Storage Fusion Data Foundation storage nodes. Only compute nodes with available HDD or SSD/NVMe disks can be viewed as candidate nodes and they get displayed in the table.
    The table includes Name, Disks, Disk size (TiB), CPU, and Memory (GiB) details about the node.
    For example, the recommendation can be to select a minimum of 3 nodes with an aggregation of at least 30 CPUs and 72 GiB memory.
  6. In the Summary section, check the capacity configuration and click Next.
  7. In the Additional settings section, you can toggle to enable dedicated nodes for infrastructure. It changes compute nodes to infrastructure nodes.
    When the Global Data Platform service is enabled, the Dedicated nodes for infrastructure button is not visible.
  8. In the Enable encryption section, enter the following details:
  9. Click Configure.
    The Data Foundation page now includes Usable capacity, Health, and Storage nodes sections:
    Important: If you use an external device, then the Storage nodes list is not available instead the following message is displayed:
    External mode Data Foundation is deployed in external mode.
    Note: Sometimes, it can take up to five minutes to show the summary of Usable capacity and Health sections.
    Usable capacity
    The amount of capacity that is available for storing data on a system after the RAID or mirroring technology is applied. In IBM Storage Fusion Data Foundation, it is 1/3 of the raw capacity when you use three replicas. Usable capacity is represented in a line graph. The block, file and object are distinguished by different colors.
    Health
    It includes Storage cluster and Data resiliency. The status gets displayed only after the provisioning is complete. You can check in the Storage > Data Foundation. Go to Storage Systems to see the created storage file system. Open the file system and in the Overview tab. In the Storage > Persistent Volumes page, you can view the local persistent volumes based on the selected disk.
    Storage nodes
    It includes a list of all nodes that are used in your local storage configuration. The node details listed in the table are Name, Status, Disks, Disk size (TiB), CPU, and Memory (GiB). You can use the search option to filter and search for nodes. You can add nodes to scale up. For the procedure to add nodes, see Adding nodes to your IBM Storage Fusion Data Foundation storage..
