MINIMUM SYSTEM REQUIREMENTS
To utilize the RAID, the minimum system configuration in the host computer requires the following:
3.5 or 2.5 inch SATA-compatible hard drive and/or 2.5-inch Solid State Drive(s) (SSD) are required for
the RAID System. Once the hard drive and/or SSD are formatted, the actual available storage
capacity can vary depending on the selected operating environment (normally 5-10 % less).
HARDWARE REQUIREMENTS AND PRECAUSIONS
1. Whenever turning off or unplugging the Rocsecure DE51 Series from your computer system becomes
necessary, always remember to safely remove it from your operating system first.
2. When the Rocsecure DE51 is connected to the computer system, it’s prohibited to remove, insert or
swap the hard drive while data transfer is being performed.
3. If you will be incorporating either software or hardware RAID functionality to operate with the ST4
Series, it is important to understand the RAID level and its component that will be incorporated and
the precautions to take as each RAID level and component may function differently and contains
various limitations.
4. If installing your own HDD, please make sure that the hard drives are free from bad blocks or defects
prior to installation in order to avoid system crashes or data loss.
5. It is highly recommended for users to back up important data contained within the drives of the
Rocsecure DE51 Series on a regular basis or whenever the user feels necessary to a remote or a
separate storage device. Rocstor will not be responsible for any loss of data caused during the use of
the DE51 Series or the recovery of the data lost.

Operation
To operate the Rocsecure DE51, the Secure Key Token must be inserted before the unit is powered up. This
will enable the system to validate the encrypted codes in the token key and enable the drives to power up.
When the Rocsecure Token Key is recognized and active, the PWR LED light on the front of the unit will lite up.
While the PWR LED is on, the Secure Token Key may be removed and stored in a safe location. If the power is
turned off, or the RESET button on the Secure Key Module in front of the unit pressed, then the Secure Key
Token needs to be inserted in for the for the PWR LED and the access to the drives is restored. If the PWR LED
is not on, the Token Key must be inserted in order to the storage unit to be accessed.
The Host Activity LED will activate to ON which will indicate a connection to an eSATA or USB host adapter.
The light will flicker to indicate activity between the Rocsecure DE51 RAID tower and the computer. The HDD
LED on this unit is normally dark and will also flicker to indicate activity between the RAID Tower and the
computer. The RAID Error LED will glow if a RAID is defined and is either in a degraded or offline state. It will
flicker to indicate a fault-tolerant RAID is rebuilding with a spare.
Installation
1. Make sure rear power switches are in the OFF position..
2. Connect Power Cord to the unit..
3. Connect the computer to DE51 via eSATA Cable.
4. Mount Turn on main power switch on the back of the unit.
Drive Installation
A. Be sure all doors are unlocked, use the provided keys to unlock if needed.
B. Gently pull the lever on the door to release it.
C. Insert the drive as shown on the label inside the door. The SATA connector toward the rear, with label side to
the right. The drive should slide in easily, don't force it.
D. Close the door on the drive bay. It should also give little resistance, don't force it. It can help to slightly tug the
lever while snapping the door shut to make it easier. As soon as the drive is in position it will power up.
E. The drives may be locked in place if desired.
IMPORTANT NOTE: There is no back door for the Rocsecure DE51 encrypted hard drives if the Secure Key Token
is lost or stolen .
IMPORTANT NOTE: all hard drives installed MUST be RAID compatible hard drives, with same
capacities and speeds of 7,200 R.P.M. or higher and preferably from the same manufacturer of hard
drives.

Rocstor® Rocsecure® DE51 [12]
Secure Key Token
The Three Secure Token keys have identical encryption code. It is recommended, one of these keys should be
kept in a safe and secure location. If you are down to the last key, make a backup of all the data stored inside
your Rocsecure DE51 tower prior to sending the last key to Rocstor for duplication.
Rocstor is not responsible for key lost in the mail or retrieval of the data inside the encrypted hard drive.
IDENTIFYING HARD DRIVES
If you are using the Rocsecure DE51 to encrypt multiple hard drives, it is important to label your hard drives if
you are taking the drive out of the DE51. The encrypted drive will act like a brand new drive when attach
directly to the SATA controller of a computer. There will be no partition or any hint to indicate that the drive
contains encrypted data. When the drive is partitioned, all the encrypted data will be lost. The same holds
true if a hard drive already has data on it is installed into the Rocsecure DE51. The computer detects the hard
drive as a brand new unallocated drive. Once you proceed to partition the drive, the data on the hard drive
will be erased and cannot be recovered.
PORT MULTIPLIER COMPATIBILITY
When configured as a set of individual drives and connected to a SATA or an eSATA host adapter, the Port
Multiplier will only work with a Port Multiplier aware host. This includes setting up the unit with more than
one array. Identify your host controller and check with its hardware manufacturer if you are unsure. Rocstor
offers several Port Multiplier aware host adapters.
Using identical drives for all settings other than JBOD or LARGE is strongly recommended. Creating a LARGE
array using drives that have different properties will use all space on all members, and performance will match
that of the member in use during any particular I/0 operation. Creating a RAID using drives that are not all the
same size will result in all members using only as much space as the smallest member. Creating a RAID using
drives that have different performance will degrade the overall performance of the array.
PORT MULTIPLIER MODES
The Port Multiplier supports individual drives (JBOD Mode), several types of RAID and some non-RAID drive
sets. Each configuration has different properties and requirements, as follows:

Rocstor® Rocsecure® DE51 [13]
RAID SELECTION
JBOD (INDIVITUAL DRIVES)
Minimum number of drives: 1
Unit Capacity: 100% of each drive
Fault Tolerance: None
Spare: No
JBOD mode offers all connected units to the host adapter, no RAID is defined at all.
Note: JBOD mode requires a SATA controller featuring Port Multiplier support for eSATA connections
Note: Optical drives can only be configured as JBOD using an eSATA connection.
RAID 0 (STRIPE SET)
Minimum number of drives: 2
Unit Capacity: size of each drive times number of drives.
Fault Tolerance: None - if any drive is lost all data is lost
Spare: No
RAID 0 "stripes" the file system across the array by placing "chunks" of data sequentially between drives in a
specific order
RAID 1 or 10 (MIRROR SET, STRIPE OR MIRROR SETS)
Number of drives: 2 (RAID 1) or 4 (RAID 10)
Unit Capacity: size of one drive (RAID 1) or size of two drives (RAID 10) times Number of drives.
Spare: Yes, if EZ mode is not disabled and 3 (RAID 1) or 5 (RAID 10) drives are present, the array will be
initialized with a spares
Fault tolerance: RAID 1 can withstand the loss of one drive without losing data. RAID 10 can withstand the loss
of one drive from each mirror set without losing data. RAID 1 works by duplicating the exact same data on two
drives. RAID 10 works by using two RAID 1 sets configured as members of a RAID 0. Disks 1 and 2 are mirrored,
disks 3 and 4 are mirrored, and the two mirror sets are striped together mode offers all connected units to the
host adapter, no RAID is defined at all.

Rocstor® Rocsecure® DE51 [14]
RAID 3 (STRIPE SET WITH DEDICATED PARITY)
Minimum number of drives: 3
Unit Capacity: size of one drive times number of total drives minus one.
E.g. (4TB x 5 drives –1 Drive = 16TB)
Spare: Yes
Fault tolerance: can withstand the loss of one drive without losing data. RAID 3 works by striping data for
individual i/0 blocks across all members except one, which contains parity data for the stripe set computed
internally by the Port Multiplier. In the event of failure, the missing information can be calculated using the
parity information.
RAID 5 (STRIPE SET WITH STRIPED PARITY)
Minimum number of drives: 3
Unit Capacity: size of one drive times number of total drives minus one.
E.g. (4TB x 5 drives –1 Drive = 16TB)
Spare: Yes
Fault tolerance: can withstand the loss of one drive without losing data. RAID 5 works by striping data for
individual i/0 blocks across all members of the set, with each member taking turns carrying parity data
computed by the Port Multiplier. In the event of failure, the missing information can be calculated using the
parity information.
CLONE (MIRROR SET)
Minimum number of drives: 2
Unit Capacity: size of one drive.
Spare: Yes
Fault tolerance: can withstand the loss of any number of drives without losing data as long as at least one
complete member remains online. CLONE mode works the same way as RAID 1, by maintaining a complete copy
of the entire set of data on each drive..

Rocstor® Rocsecure® DE51 [15]
LARGE (SPANNED SET)
Minimum number of drives: 2
Unit Capacity: 100% of all drives together regardless of differences in size.
Spare: No.
Fault tolerance: cannot withstand the loss of any drives without losing data. However, some data may be
recovered as long as the drive(s) carrying the filesystem data (boot record, directory, etc.) remain online. LARGE
mode is neither a RAID nor is it a JBOD. It works by declaring the sum of all available space of the member drives
as a single unit, without striping the data. As each member is filled, new data is stored on the next...
NOTES ABOUT SPARE DRIVE
If EZ mode is disabled (SW1: 2 ON), all individual drives not configured as array members will be offered to the
host adapter as separate units. To create an array with one or more spares, set or modify the RAID mode while
the spares are disconnected from the Port Multiplier. When EZ mode is enabled (SW1 :2 OFF), individual
drives connected when an array is present are considered spare. Spare drives must be equal to or larger in size
than the smallest member. When any type of array is defined, individual units will be considered spare
Raid 0 and LARGE arrays are not fault-tolerant and spare drive will not be useful, therefore disabling EZ for
these arrays is recommended. When a spare drive is present and fault-tolerant RAID (1, 10, 3, or 5) is defined,
EZ Mode will automatically rebuilt any available spare into the array to replace failed drive.
RESETTING RAID
NOTE: This procedure destroys all RAID data. It should not harm individual drives or their contents; however,
creating backups of all data is strongly recommended before proceeding. Be sure the port multiplier is
connected to an active host before proceeding. The port multiplier will not complete the process if it has no
host connection.
1. Power down the unit and set the dip switch to the desired RAID Mode.
2. While holding the SET button, turn the unit on. A long beep will sound from the Port Multiplier. The SET button
may be released once the long beep starts. Shortly after releasing the SET button, the port multiplier should
"chirp" to indicate the process is complete. If instead of a chirp the Port Multiplier sounds a series of short
beeps, an error has occurred during the process.

Rocstor® Rocsecure® DE51 [16]
SETTING OR MODIFYING THE RAID MODE
NOTE: Setting or modifying the RAID mode destroys all data. Be sure the port multiplier is connected to an
active host before proceeding. The port multiplier will not complete the process if it has no host connection.
1. Follow the procedure for resetting the RAID Mode.
2. Power down the unit and set the dip switch to the desired RAID Mode.
3. While holding the SET button with a ball point pen, turn the unit on. A long beep will sound from the Port
Multiplier. The SET button may be released once the long beep starts. Shortly afterward, the port multiplier
should "chirp" to indicate the process is complete. If instead of a chirp the Port Multiplier sounds a series of
short beeps, an error has occurred during configuration of the array.
BZS SWITCH (SW1: 1)
The BZS switch is used to silence the audible alarm buzzer. The OFF position permits the audible alarm, and
the ON position silences the audible alarm. The BZS switch has immediate effect.
EZ SWITCH (SW1: 2)
The EZ (spare) switch inhibits spares when ON. When in the OFF position, all individual drives (not defined as
members of an array) are considered spare and are not offered to the operating system. Should a RAID
become degraded, when the EZ switch is in the OFF position a spare drive will be used automatically to rebuild
the RAID, if present. EZ mode is determined when the unit is powered up. Changing the switch will have no
effect until the unit has been re-powered.
Warning: turning off the EZ switch to rebuild an array will consider any drives not declared array members to
be eligible for rebuild as a spare. Rebuilding will destroy all existing data on that drive and the drive chosen is
not predictable. Disconnect any individual drives with valuable data on them before enabling EZ Mode.
RAID Mode Switches M2, M1, MO (SW1 :3 - SW1 -5)

Rocstor® Rocsecure® DE51 [17]
RAID MODE SWITCH SETTING
The RAID Mode switches define what type of RAID will be initialized when the unit is powered
up while the RAID Mode button is held down, as follows:
