The Infoblox TE-1606 appliance uses a RAID 1 (Redundant Array of Independent Disks) array, also known as Disk (drive) mirroring, which offers the optimal combination of high database performance, high stability, and disk failure recovery.

RAID 1 is a data replication that requires a minimum of two disks to provide data redundancy by mirroring data. In this configuration, data is stored simultaneously on multiple drives, resulting in an exact mirror copy. This feature ensures that data can still be accessed from the remaining drive(s) if one drive fails. Each device in the RAID 1 array contains same data, ensuring that the data is always accessible.
Disk mirroring is particularly advantageous for disaster recovery because it provides immediate failover for mission-critical applications' data.

RAID1 Array Configuration

Evaluating the Status of the Disk Subsystem

You can monitor the disk subsystem through the Grid Manager and the front panel LEDs for the disks. You can also view disk status by using the CLI command show hardware_status.
To see a detailed status report, log in to the Grid Manager and from the Grid -> Grid Manager tab, select the appliance, and then click the Detailed Status icon. (For more information on the Detailed Status panel, refer to the Infoblox Administrator Guide.)
The color of the RAID icon on the Detailed Status panel indicates the status of the RAID array.

The Grid Manager also displays detailed status of the RAID array. In the event of a disk failure, you must replace the failed disk with one that is qualified and shipped from Infoblox.

Disk LED Operation

The disks are located on the left side of the appliance front panel behind a removable face plate. A single LED, the top LED on the right, indicates the activity and status of each drive. The LEDs are not visible unless you remove the face plate. To do so, gently grip the left edge of the face plate and pull towards the front.
