Can I use RAID to make my system more reliable?

Yes, if you use two IDE or SATA a disk, at the initial stage of installation of system after a choice installed PBX press to create RAID 1 for used disks, the system configures RAID 1 (mirroring) on both drives. This step does not apply if you have the hardware raid controller, for that use standard settings after choosing PBX simply press Enter.
