Infoblox 2200 Series Field Replaceable Units
The Infoblox 2200 Series appliances provide for several replaceable units in the system:
• Hard disk drives
• Fan modules
• AC power supplies
• SFP/SFP+ Transceivers
All replaceable units must be replaced with parts of the same specifications as described in this section. You can
also order some parts as local spares. For information about compatible parts and their part numbers, see
Table 4
on page 41.
Managing the Infoblox 2200 Series Disk Subsystem
The Infoblox 2200 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 Figure 15. 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.
