All replaceable units must be replaced with parts of the same specifications as described in this section. For parts and replacements, contact your
Infoblox field representative or Infoblox Technical Support. You can also order some parts as local spares.
Managing the Disk Subsystem
The Infoblox 4005 Series appliances use a RAID (Redundant Array of Independent Disks) 10 array to provide the optimum mix of high database
performance and redundant data storage with recovery in the event of disk failures. The disk array is completely self managed, with no
maintenance or special procedures required to service the disk subsystem.
RAID 10 (or sometimes called RAID 1+0) uses a minimum of four disk drives to create a RAID 0 array from two RAID 1 arrays, as shown in the
fig
It uses mirroring and striping to form a stripe of mirrored subsets. The RAID array combines—or stripes—multiple disk drives, creating

a single logical volume (RAID 0). RAID 10 combines the high performance of RAID 0 and the high fault tolerance of RAID 1. Striping disk drives
improves database write performance over a single disk drive for large databases. The disks are also mirrored (RAID 1), so that each disk in the
logical volume is fully redundant.
RAID-10 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 disk drives. 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
->
tab, select the appliance, and then click the

Detailed Status icon. (For more information on the

Detailed Status
Infoblox Administrator Guide
The color of the RAID icon on the
panel indicates the status of the RAID array on the 4005 Series appliances.
Detailed Status
RAID Array LED States
Color
Meaning
Green
The RAID array is in an optimal state.
Yellow
A new disk was inserted and the RAID array is rebuilding.
Red
The RAID array is degraded. At least one disk is not functioning properly. The Grid Manager lists the disks that are online. Replace
only the disks that are offline.
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 and has the same disk type as the rest of the disks in the array. The appliance displays information about
mismatched disks in the Detailed Status panel.
Note that all disk drives in the array must have the same disk type (
) for the array to function properly. When you have a mismatched
IB-Type 5
disk in the array, promptly replace the disk with a replacement disk from Infoblox to avoid operational issues.
Disk LED Operation
The disk drives 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,
