Provisioning block storage space

Block storage space is provisioned via storage volumes connected to a target group.

Limitations

• Each node in a target group can host a single target for that group.
• Block storage space is not fully thin provisioned. After user data removal, unused storage space is not reclaimed and is reported as actual used space, which is charged according to your licensing model. For more details, refer to Logical space chart.

Prerequisites

• A clear understanding of block storage, which is explained in About block storage.
• Your hardware meets the requirements listed in Server requirements.
• Your infrastructure networks are set up, as described in Setting up networks for block storage.
• The storage cluster is created by following the instructions in Deploying the storage cluster.

Provisioning overview

1. Create a target group.
2. Create block volumes and attach them to the target group as LUNs.

3. Connect initiators to targets by using standard tools of your operating system or product (refer to "Accessing iSCSI targets" in the Storage User’s Guide).
