On the SG6060 appliance, you can change to a different RAID mode to accommodate your storage and recovery requirements. You can only change the mode before deploying the appliance Storage Node.
Before you begin
- You are using any client that can connect to StorageGRID.
- The client has a supported web browser.
About this task
Before deploying the
SG6060 appliance as a Storage Node, you can choose one of the following volume configuration options:
- DDP: This is the default and recommended mode for all appliances. When compared to RAID6, DDP delivers better system performance, reduced rebuild times after drive failures, and ease of management. This mode uses two parity drives for every eight data drives. DDP also provides drawer loss protection in a 60-drive appliance that contains a newer version of E-Series software.
- DDP16: This mode uses two parity drives for every 16 data drives, which results in higher storage efficiency compared to DDP. When compared to RAID6, DDP16 delivers better system performance, reduced rebuild times after drive failures, ease of management, and comparable storage efficiency. DDP16 is available only for 60-drive appliances. DDP16 does not provide drawer loss protection.
- RAID6: This mode uses two parity drives for every 16 or more data drives. RAID6 is only available in 60-drive appliances. Although RAID6 can increase storage efficiency of the appliance when compared to DDP, it is not recommended for most StorageGRID environments.
Attention: If any volumes have already been configured or if StorageGRID was previously installed, changing the RAID mode causes the volumes to be removed and replaced. Any data on those volumes will be lost.
Steps
- Access the StorageGRID Appliance Installer: https://SG6000-CN_Controller_IP:8443
SG6000-CN_Controller_IP is the IP address of the SG6000-CN controller on any of the three StorageGRID networks.
- From the menu bar, select .
- On the Configure RAID Mode page, select the desired RAID mode from the Mode drop-down list.
- Click Save.
