3. RAID Configuration
3.1.Hardware RAID Layout
The FS-1600 Series NAS appliance uses ARC-1160 (FS-1600) or ARC- 1261ML (FS-1610) Serial-ATA RAID II controller that can aggregate a maximum number of 16 HDD into user definable RAID levels. The minimum number of required HDD is one (or RAID 0). Tandberg Data recommends using a minimum of 4 HDD (Serial-ATA II type) in order to kick start an implementation. Subsequent HDD can be added into an already configured RAID set or a new RAID set. Please refer to the respective sections in RAID controller User Guide for details.
Upon boot up of the FS-1600 Series NAS appliance, the RAID controller BIOS can be accessed by pressing the F6 or TAB key. It is recommended that a RAID set that comprises of a 4 HDD is created first before creating subsequent Volume sets.
In this case Tandberg Data recommends two logical Volume sets consisting of System Volume and Data Volume to be created within the RAID set. The two logical volumes are to be configured to RAID levels 0+1 and 5. The System Volume, installed with the host operating system (Windows® Storage Server 2003), is organized as RAID 0+1 and the Data Volume is organized as RAID 5. This is to allow OS redundancy if more than one HDD fails.
The Volume set layout for the appliance is illustrated below.
