Access LED
The LED will be blinking blue when the eSATA host channel is busy (with data transmission).
Summary
RAID 0 is the fastest and most efficient array type but offers no fault-tolerance. RAID 0 requires
a minimum of one drive.
RAID 1 is the best choice for performance-critical, fault-tolerant environments. RAID 1 is the
only choice for fault-tolerance if no more than two drives are used.
RAID 3 can be used to speed up data transfer and provide fault-tolerance in single-user
environments that access long sequential records. However, RAID 3 does not allow overlapping
of multiple I/O operations and requires synchronized-spindle drives to avoid performance
degradation with short records. RAID 5 with a small stripe size offers similar performance.
RAID 5 combines efficient, fault-tolerant data storage with good performance characteristics.
However, write performance and performance during drive failure is slower than with RAID 1.
Rebuild operations also require more time than with RAID 1 because parity information is also
reconstructed. At least three drives are required for RAID 5 arrays.
RAID MANAGEMENT
The Guardian 4RT can implement several different levels of RAID technology. RAID levels
supported by the Guardian 4RT are shown below.
RAID Level Description Min. Drives
0
Block striping is provide, which yields higher
performance than with individual drives. There is
no redundancy.
1
1
Drives are paired and mirrored. All data is 100%
duplicated on an equivalent drive. Fully
redundant.
2
3 Data is striped across several physical drives.
Parity protection is used for data redundancy. 3
5 Data is striped across several physical drives.
Parity protection is used for data redundancy. 3
1 + 0
Combination of RAID levels 0 and 1. This level
provides redundancy through mirroring and
striping.

QUICK INSTALLATION GUIDE
reparing the and owering ON
1. Attach network cable to the R-Link port and connect the other end of network cable
to your network hub/switch.
2. Connect the eSATA cable to the eSATA port of the RAID.
3. Connect the other end of eSATA cable to the eSATA port of the eSATA card inserted in
your host system or server.
Or if you have onboard SATA port, you can connect the eSATA cable using eSATA-to-
SATA cable, and connect to the onboard SATA port.
4. Insert the key token into the key token port.
5. Connect the power cord to the AC input socket. Plug the other end of power cord to
the power source.

6. Press the Power ON/OFF Switch at the rear of the unit.
7. After power ON, the RAID model name and IP address will be displayed in the LCD
display panel.
NOTE: Default IP address is 192.168.1.100 and DHCP is enabled. If you have a DHCP
server and the RAID obtained a dynamic IP from DHCP server, the dynamic IP
will be displayed in the LCD display panel.

ROCSECURE – Guardian 4RT Secure Raid System User Manual Page | 20
Installing Hard Drives
1. Open the drive door by pressing the door lock downwards.
2. If the drive tray is locked, open the drive tray lock.
3. Remove one drive tray.
4. Place the disk drive in the drive tray. Make sure the holes of the disk drive align with the
holes of the drive tray.
5. Install the mounting screws to secure the disk drive into the drive tray.
6. Insert the drive tray into the slot. If the RAID is powered on, the HDD Status LED will
change from red into “no light” which means the drive has been detected.
Creating Raid Set and Volume Set Open web browser in a PC or MAC. Make sure your PC or
MAC have network connection to the RAID’s IP address.
1. Type in http://192.168.1.100, or if you have DHCP server, use the dynamic IP address
obtained from your DHCP server.
2. A user name and password will be required to login. Default user name is “admin” and
default password is “00000000.”
3. After login, the RAID Manager GUI will be displayed.
4. Select “Raid Set Functions” and click “Create Raid Set.” Select the disk drives that will be
included in the Raid Set. Change the Raid Set Name if needed. Tick “Confirm the
Operation” and click “Submit.” The Raid Set will be created.
