Before you start the installation of the StorageGRID Webscale appliance Storage Node, you can select the RAID volume configuration that is appropriate for your deployment environment.
Before you begin
- You must have a service laptop with a web browser already installed.
- You must already have the IP address of the management network.
About this task
Note: This setting can only be modified before you start the software installation on the StorageGRID Webscale appliance.
You can choose from two volume configuration options on the StorageGRID Webscale appliance:
- Dynamic Disk Pools (DDP): This is the default, and recommended setting. DDP is an enhanced hardware data protection scheme that delivers system performance, reduced rebuild times, and ease of management.
- RAID6: A hardware protection scheme that uses to parity stripes on each disk, and allows for two disk failures within the RAID set before any data is lost. RAID6 provides improved storage efficiency over DDP (typically 5-10%), but does not recover from failures as efficiently.
Steps
- Using the service laptop, open a web browser and access the RAID6 Option web page on the StorageGRID Webscale appliance: http://Management_Port_IP:8080/advanced
Management_Port_IP is the Management Port 1 IP address of the E5600SG controller that was provisioned during the physical installation.
- If you want to change from the default DDP value to RAID6:
- Click Change volume configuration to RAID6.
- Click OK in the confirmation dialog box.
- If you have selected RAID6 and want to restore DDP:
- Click Change volume configuration to DDP.
- Click OK in the confirmation dialog box.
