1.3 Consider your RAID Configuration

If you purchased RAX QR with drives pre-installed and pre-configured, skip to Hardware Setup.

RAX QR supports RAID 0, RAID 1 and a single drive. Consider which configuration best suits your needs.

All hard drives must be initialized prior to use in RAX QR. It is not possible to add a drive to RAX QR and

access existing data on that drive. Before it can be readable, the hard drive must be initialized by RAX

QR which will cause the loss of all data on the drive. The drive(s) must be configured to RAID 0, RAID 1

or a single drive.

1.3.1 RAID 0

In this mode, RAX QR will configure the drives in a "striped" RAID. This will split your data between the

drives, offering faster performance and allowing you to use the full capacity of the drives in a single

volume. However, RAID 0 offers no data redundancy, so all data is unrecoverable if either drive fails.

1.3.2 RAID 1

In this mode, RAX QR will "mirror" the two drives for best data protection. In this mode, you will work with

a single volume equal in size to the capacity of one drive. When you copy data to the volume, RAX will

simultaneously write the data to both drives. If one drive were to fail, your data would still be preserved on

the other drive. After replacing a failed drive you can rebuild the RAID on the fly so that your data is once

again redundant and secure.

1.3.3 Single Disk Mode

In this mode RAX QR will support a single drive.

Because your RAX QR features a redundant RAID mode which protects against a hard drive mechanical failure, it

is an excellent part of any backup strategy. However, a RAID is not, in itself, a backup strategy. Many things

besides hard drive failure can compromise your data (e.g. malware, theft, fire, etc.) That's why it's important to

have another copy of your data somewhere else. Follow the 3-2-1 backup rule: your data should exist in three

different places on two different storage media and at least one of those copies should be maintained offsite.

If you do not have an effective backup strategy, you may not be able to recover your data, or the cost of recovery

may be quite expensive. Our warranty does not cover costs associated with data loss (nor do the warranties of

other hard drive manufacturers). We know it would be heartbreaking to lose your data, so please plan

accordingly!

2.1.1 HDD installation for RAX210-QR

Follow these steps for installing or removing a hard drive

from the front bays.

a) Pull on the ejection handle and open the door.

b) Slide in your SATA hard drive, connector-end first.

Note: the drive's label should be facing up.

c) Shut the door.

NOTE: There is no way to convert a drive

in Single Disk Mode to RAID 1 without

creating a new array which will cause the

loss of data on the hard drive.
