1.5.2 Fan Alarm Mute Button

To adjust your RAID settings, there are 3 switches on the back of the OWC Mercury

Rack Pro.

Use the silkscreened settings as a guide when adjusting the switches to the desired

RAID setting. Proceed to section “1.6 RAID Settings” for instructions on changing the

RAID levels on the OWC Mercury Rack Pro.

1.6 RAID Settings

1.6.1 Changing the RAID Mode

IMPORTANT NOTE: Drives of identical model are required for all RAID types other

than Clear & JBOD (Independent Drive) Mode and JBOD (SPAN) “Combine” Mode.

IMPORTANT NOTE: Changing the RAID setup will require you to reformat the drives.

Reformatting deletes all of the existing data on the drives!

Make sure that you have backed up your data before proceeding!

To switch or clear RAID modes, follow these steps:

In the event one of the fans within the OWC Mercury Rack Pro fails, an alarm will

sound. The “Fan Alarm Mute” button located on the rear panel of the unit, will mute

the alarm. It is recommended to replace the failed fan as soon as possible in order to

adequately cool the unit, prevent damage to components, and avoid data loss.

1.5.3 RAID Selector Switches

➀ With the OWC Mercury Rack Pro turned OFF, adjust the switches on the back of the

unit to the desired setting (either to “Clear RAID” mode or to a RAID level).

➁ While holding down the SET button, power ON the OWC Mercury Rack Pro. Keep

holding the SET button until you hear a full beep (you may hear shorter chirps or

beeps while the unit is setting itself into the RAID mode). The lights on the Rack Pro

will also ash during this process and will stop ashing when complete.

➂ The OWC Mercury Rack Pro is now set to the newly selected mode. If the Rack Pro

has just been set to “Clear RAID” mode, you can now repeat steps ➀and ➁to apply a

RAID setting. If the Rack Pro has just been set to a RAID mode, it is now ready to be

formatted. Instructions for formatting can be found in Chapter 3 of this manual.

IMPORTANT NOTE: Changing the RAID settings requires you to set the

Rack Pro to“Clear RAID” mode between each mode change.

OWC Mercury Rack Pro Chapter 1 - Introduction

1.6.2 RAID Modes

IMPORTANT NOTES:

Drives of identical size and model are required for all RAID types

other than Clear & JBOD (Independent Drive) Mode and JBOD

(SPAN) “Combine” Mode.

Changing the RAID mode will require you to reformat the drives.

Be sure to back up your data ﬁrst!

Clear & JBOD (Independent Drive) Mode

Switch setting: DOWN-DOWN-DOWN

Each drive will appear as a single volume. If you wish to use a mixed variety of capac-

ity and model drives, this is the mode to use. To swap or replace drives, dismount all

drives and power the OWC Mercury Rack Pro o.

JBOD (SPAN) “Combine” Mode

Switch setting: UP-DOWN-UP

The drives show up as one large single volume. The total size will depend on the

drives installed, you can use drives of dierent capacities. JBOD (SPAN) is an array (not

RAID) in which the data is written across drives sequentially. This is done to combine

the capacities of the drives, but it does not provide any performance or redundancy

benets.

RAID 0 “Drive Striping” Mode

Switch setting: UP-UP-UP

The drives show up as one large single volume. RAID 0 is used when speed is the pri-

mary objective, but does not have any redundancy for protection. Data is alternated

very quickly across two or more drives to gain speed by essentially distributing the

workload. Since data is written without parity data-checking, it allows for the fastest

data transfer rates, but if one drive fails, the whole array can become corrupted and

data will be lost. Always maintain a backup of your data!

Storage Capacity Data Safety Performance

! !

OWC Mercury Rack Pro Chapter 1 - Introduction

RAID 1 “Drive Mirroring” Mode (2 drives installed only)

Switch setting: UP-UP-DOWN

The drives show up as one volume, but only 50% of the total capacity can be used. It is

highly recommended to use identical drives for this RAID method. However, while you

can utilize drives of dierent capacity, the RAID size will be based on the smallest ca-

pacity total of the drives used in the RAID set. RAID 1 creates an exact copy (or “mirror”)

of a set of data on the second drive. This is useful when reliability and backup are more

important than capacity. When one drive fails, it can be replaced and the data rebuilt.

RAID 10 “Drive Mirroring with Striping” Mode

Switch setting: UP-UP-DOWN

The drives show up as one volume, but only 50% of the total capacity can be used,

depending on the drive with the smallest capacity. RAID 10 creates an exact copy (or

“mirror”) of a set of data but also uses a RAID 0 Stripe for speed. When one drive fails, it

can be replaced and the data rebuilt automatically.

RAID 3 “Drive Striping with Dedicated Parity” Mode

Switch setting: UP-DOWN-DOWN

The drives show up as one volume, but the total capacity, depending on the drive with

the smallest capacity, is the combined size minus the size of one drive. RAID 3 uses

byte level striping with parity data located on 1 drive. Very fast performance can be

achieved with RAID 3 while also maintaining fault protection, so if one drive fails, it can

be replaced and the data rebuilt automatically.

RAID 5 “Drive Striping with Distributed Parity” Mode

Switch setting: DOWN-UP-DOWN

The drives show up as one volume, but the total capacity, depending on the drive with

the smallest capacity, is the combined size minus the size of one drive. RAID 5 uses

block level striping with parity data distributed across all member disks and therefore

provides the perfect balance between high performance and data integrity. When one

drive fails, it can be replaced and the data rebuilt automatically.

OWC Mercury Rack Pro Chapter 2 - System Setup

2.1 Drive Installation

NOTE: If you purchased a precongured solution with drives included, each drive has a

dierent colored dot on it. Use these 4 dierent colored dots to match the drive to the

appropriate drive bay.

To install your own drive mechanisms:

➀Open the front door on the

OWC Mercury Rack Pro.

➁Install the drive as shown to

the left, with the SATA connector

facing away from you.

➂Slide the drive all the way into

the drive bay. It will t ush with

the aluminum frame.

➃Repeat the previous steps for

each drive you are installing.

NOTE: Be careful to not damage any components, and do not force the drives into

place. If they don’t slide in easily, make sure there are no obstructions.

IMPORTANT - ADDING DRIVES TO AN EXISTING RAID SET:

It is not possible to add more drives to an existing RAID array or change the RAID

conguration without reformatting. To add additional drives at a later point, with the

OWC Mercury Rack Pro turned OFF, adjust the switches on the back of the unit to the

Clear RAID setting (down-down-down). Power the OWC Mercury Rack Pro ON while

holding down the SET button right next to it. This will clear the existing RAID settings

out. Once the unit has beeped and the drive access lights stop ashing, you can

release the buttons and press the power button again to turn the enclosure o. You are

now able to change the switches to whichever RAID setting you wish to use.

IMPORTANT - ADDING DRIVES TO AN INDEPENDENT (CLEAR RAID) SET:

You can remove any drive from a Clear RAID set and replace it with another drive by

powering the OWC Mercury Rack Pro o, and replacing the drive. NOTE: To avoid

corruption it is essential to eject (unmount) all drives and power the unit o.

2 SYSTEM SETUP

OWC Mercury Rack Pro Chapter 2 - System Setup

2.2 Replacing Drives

When one of the drives

fails, the corresponding

activity LED will light up

solid red and the alarm

will sound. To disable

the alarm, press the SET

button once. If only one

drive is defective and the

RAID mode is set to RAID

1, RAID 3, RAID 5, or RAID

10, the data can still be

accessed, but we strongly

suggest that you replace

the faulty drive mecha-

nism immediately with an identical model / capacity drive to assure continued backup

and data safety. To remove the drive from the enclosure, simply use the ip lever

located above the drive to eject the drive mechanism.

If more than one drive fails at the same time, or if one drive fails and the RAID mode

is set to RAID 0 or Combine/Span, the data is lost (in Combine mode, only on that one

drive) and the system cannot be accessed again until the drive(s) are replaced and a

new array is built.

➀ Check the HDD LED and replace the faulty drive. The red LED indicates the defective

drive. You do NOT need to power the enclosure o to do this.

➁ For RAID 1, RAID 3 RAID 5, and RAID 10, the RAID array will be rebuilt automatically.

During the rebuild process, the drive LED will ash red. Rebuilding the RAID array will

take several hours to days, depending on drive capacity. Once the rebuild is complete,

the LED will turn o, or ash red with activity. Power cycle the rack enclosure to return

to normal LED operation.

➂ For RAID 0 and Combine/Span, mode, the corresponding LED will turn blue show-

ing that the defective drive is replaced and a good drive is inserted into the bay. You

will need to clear and reset your RAID. See section 1.6.1 for details on how to do that.

NOTE: Combined drives or independent drives can have the data from the good drives

recovered in most cases.

NOTE: We recommend not turning the power o during the rebuild process but if it is

interrupted, it will continue rebuilding the data as soon as the power is restored. The

OWC Mercury Rack Pro does NOT need to be connected to a computer for the rebuild

process to complete.

Cable Connections:

➀Plug the power cable into the wall and into the OWC Mercury Rack Pro.

➁ Connect the eSATA, FireWire 800, FireWire 400, or USB 3.0 cable - appropriate for the

interface your computer supports - into the drive and computer. (eSATA recommended

for maximum performance)

If sold as a precongured solution, your OWC Mercury Rack Pro is preset as a RAID 5,

using the “Mac OS Extended” format and is ready to use. If you want to change this

conguration, please follow the instructions in Chapter 3 to do so.

A few precautions and notes when using your external storage device:

• Do not expose the product to water or humid conditions.

• Do not cover the enclosure’s ventilation holes.

• Only one interface (eSATA, FW800, FW400, USB 3.0) at a time can be used.

• When more than one interface cable is connected, the fastest interface has

priority. To use a dierent interface, dismount the drive from the computer via the

operating system, then disconnect the interface cable you are changing from rst

before connecting the new interface cable.

• Before connecting the device to your computer, install the drives, and set your

preferred RAID mode.

• For the safe removal of your drive and to assure that no data is lost, always eject or

unmount the drive from your operating system before powering o. See section

4.2 for that procedure.

• In order for the computer to access volumes larger than 2TB, the Operating

System need to support large volumes (e.g.: Windows Vista 32bit/64bit or Mac OS

X 10.4 and above).
