HDD mirroring feature (option)
●
Overview
This option enables HDD data mirroring (RAID1).
When one HDD is crashed, the other HDD backs up the operation. This minimizes the
downtime due to crash, thus enhancing the reliability as the document server.
Mirroring is performed in the following 2 ways depending on HDD capacities (160GB or 1TB).
The mirroring PCB controls the reading / writing timing of HDD data.
The LED PCB indicates HDD operation statuses by LED.
