RAID6 – This is 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.
Note:
The SG5612 does not support RAID6. If you have this model, you must use the DDP
option.
Steps
1. 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 IP address of management port 1 on the E5600SG controller
controller (provisioned during the physical installation).
2. If you want to change from the default DDP value to RAID6:
a. Click Change volume configuration to RAID6.
b. Click OK in the confirmation dialog box.
3. If you have selected RAID6 and want to restore DDP:
a. Click Change volume configuration to DDP.
b. Click OK in the confirmation dialog box.
