2.1 Summary of RAID Levels

The RTX Secure 410-QR supports RAID Levels 0, 1, 3, 5, and 10.

RAID Level 5 is most commonly used by those seeking an optimal

balance of speed and data safety.

RAID Features and Performance

RAID

Description

Level

Also known as striping. Data distrib-

uted across multiple drives in the

array. There is no data protection.

Also known as mirroring. All data

replicated on two separate disks. This

is a high availability solution, but due

to the 100% duplication, only half

the total disk capacity is available for

data storage.

Also known as Bit-Interleaved

Parity. Data and parity information

is subdivided and distributed across

all disks. Parity must be equal to the

smallest disk capacity in the array.

Parity information normally stored on

a dedicated parity disk.

Also known as Block-Interleaved

Distributed Parity. Data and parity

information is subdivided and distrib-

uted across all disks. Can withstand

the failure of one drive. The total

capacity of all but one of the drives is

available for data storage.

Also known as Block-Interleaved

Parity. Data is striped across two

separate disks and mirrored to

another disk pair.

*If both drives in either the RAID 0 or RAID 1 set fail, then the entire RAID will fail. If

only one drive in each of the RAID 0 and RAID 1 sets fail, then the RAID is preserved.

2.2 Hot Spares (Host Standby)

RAIDs 3 and 5 are the two RAIDs available with the RTX that will

support hot spares. Hot spares are connected as part of your RAID

and are switched into operation when a drive fails. In other words,

if you setup "3 + Host Standby" with your RAID 3 or 5, then the RTX

will immediately rebuild the RAID if a drive should happen to fail.

After that a new drive will need to be inserted, preferably the same

model of the drive that needs replaced.

3. Installation Steps

a. Pull the ejection handle on the TrayFree bay to open the bay

door.

b. Insert a SATA hard drive into the bay. Make sure it is label-side

up with the SATA connection on the drive inserted first toward

the rear of the enclosure.

c. Shut the bay door.

d. You can option-

ally secure each

bay door by

inserting an RTX

Key into its key

lock and turning

it 90 degrees

clockwise.

Doing so is not

necessary to operate the RTX Secure.

Sticker Card

Use the stickers on the provided sticker card to label each drive if

you plan to use Unique Encrypted Mode (see Section 3.2). This will

prevent the drives from getting mixed up when they are removed

from the bays.

3.2 Setting the Encryption Mode

The RTX Secure has three modes that determine how it handles

Security Keys. The status of the mode is determined at power up.

After the unit has been successfully mounted by the system, the

Security Key may be removed and stored in a safe location. Changing

the position of the switches on the bottom of the RTX after the unit

has successfully been mounted will also not change the mode used

at power up.

Unique Encrypted Mode

This is the most secure mode of operation. A Security Key is required

to access data, and each bay is loaded with its own unique 256-bit

security value from the Security Key. These security values are all

stored in one Security Key. Flip the left switch on the bottom panel

switch down to "Encrypted."

down to "Unique" and the right

Common Encrypted Mode

This mode allows hard drives to be located in different boxes after

the array is formatted. A Security Key is required to access data.

Each bay uses the same security value from the Security Key. Flip the

left switch on the bottom panel up to "Common" and the right switch

down to "Encrypted." The Encryption Display Common Key LED will

illuminate.

Bypass Mode

A Security Key is not required to access data. This option cannot be

used with encrypted hard drives. Flip the right switch on the bottom

panel to "Bypass." This option disables the Common/Unique switch.

The Encryption Display Bypass LED will illuminate and the drive bay

Encryption Active LEDs will remain off.
