Provisioning storage by creating a Flash Pool aggregate manually

You can use System Manager to create a Flash Pool aggregate manually, or to convert an existing HDD aggregate to a Flash Pool aggregate by adding SSDs. When you create a new HDD aggregate, you can provision an SSD cache to it and create a Flash Pool aggregate.

About this task

Steps

  1. Create an aggregate by using one of the following methods:
    • Click Applications & Tiers > Storage Tiers > Add Aggregate.
    • Click Storage > Aggregate & Disks > Aggregates > Create.
  2. Enable the Manually Create Aggregate option to create an aggregate.
  3. In the Create Aggregate window, specify the name of the aggregate, the disk type, and the number of disks or partitions to include for the HDDs in the aggregate.
  4. If you want to mirror the aggregate, select the Mirror this aggregate check box.
    For MetroCluster configurations, creating unmirrored aggregates is restricted. Therefore, the mirroring option is enabled by default for MetroCluster configurations.
  5. Click Use Flash Pool Cache with this aggregate.

      3. Click Save.
  7. Click Create.

Result

The Flash Pool aggregate is created with the specified configuration, and is added to the list of aggregates in the Aggregates window.
