Optional: Changing To Raid6 Mode - NetApp StorageGRID Webscale SG6000 Series Installation And Maintenance Manual

56 | Hardware Installation and Maintenance Guide for SG6000 Appliances
Steps
1. From the BMC dashboard, select Settings > SNMP Settings.
2. On the SNMP Settings page, select the Enable SNMP V1/V2 checkbox, and provide a Read-
Only Community String and a Read-Write Community String.
The Read-Only Community String is like a user ID or password. You should change this value to
prevent intruders from getting information about your network setup. The Read-Write
Community String protects the device against unauthorized changes.
3. Optionally, select Enable Trap, and enter the required information.
Enable traps if you want the SG6000-CN controller to send immediate notifications to an SNMP
console when it is in an unusual state. Traps might indicate link up/down conditions, temperatures
exceeding certain thresholds, or high traffic.
4. Optionally, click Send Test Trap to test your settings.
5. If the settings are correct, click Save.

Optional: Changing to RAID6 mode

You can change the volume configuration from its default and recommended setting, Dynamic Disk
Pools (DDP), to RAID6. 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 Webscale.
• The client has a supported web browser.
About this task
Before deploying the SG6060 appliance as a Storage Node, you can choose from two volume
configuration options:
• Dynamic Disk Pools (DDP) – This is the default and recommended setting. DDP is an enhanced
hardware data protection scheme that delivers better system performance, reduced rebuild times
after drive failures, and ease of management.
• RAID6 – This is a hardware protection scheme that uses parity stripes on each disk, and allows
for two disk failures within the RAID set before any data is lost.
Using RAID6 is not recommended for most StorageGRID Webscale environments.
Attention:
Although RAID6 can increase storage efficiency to 88% (compared to 80% for DDP), DDP
mode provides more efficient recovery from drive failures.
If any volumes have already been configured or if StorageGRID Webscale was
Attention:
previously installed, changing the RAID mode causes the volumes to be removed and replaced.
Any data on those volumes will be lost.
