2HDD system (optional)

When the device ships, the second hard disk is connected to SATA port 2. This hard disk
drive is not set up. This gives you the option of backing up your data to this hard disk. For
information on hard disk capacities, refer to your order documentation.
Booting from the slave hard disk
In order to allow booting from the second hard disk, you need to configure it as the primary
boot device. Make the following settings in your BIOS Setup:
Select Boot > Legacy > Hard Disk Drive > <Hard disk name> e.g. P0- ST3500418AS, then
press the "+" key to move it up in the boot order.
Note
The drive letters for the partitions on both drives are assigned by the operating system used.
You can change these in the Control Panel as required.

RAID system

4.4.5.1

RAID1 system

This is a RAID1 system configuration (data mirroring with two drives). This means that if
there is a defective hard disk drive or there are cable problems, the system can continue to
operate in one channel and achieve a high degree of availability.
Note
You will find information about the Intel
"Drivers\RAID\Intel" directory on the "Documentation and Drivers" DVD that ships with the
product.
Additional information on RAID1 systems can be found in the section "Managing RAID
systems (Page 90)".
4.4.5.2

RAID5 system

This is a RAID5 system configuration (striping with parity). This means that if there is a
defective hard disk drive or there are cable problems, the system can continue to operate in
one channel and achieve a high degree of availability.
Note
You can find information about the Intel® RAID controller in the RAID documentation in the
"Drivers\RAID\Intel" directory on the supplied "Documentation and Drivers" DVD.
Additional information on RAID5 systems can be found in the section "Managing RAID
systems (Page 90)".
