IMPORTANT NOTICES
Safety Notices
•The warranty is void if an unauthorized person attempts and/or repairs the hard disk drive.
•Read all Manuals and instructions carefully before using the device.
•Do not spill any liquid or insert any object into the device.
•Use the device within the specifications indicated, including but not limited to: power
requirements, temperature, humidity, sunlight and magnetism from other devices such as
computers and televisions.
•Please visit the Rocstor website, www.rocstor.com for further information concerning
specifications and use of the device.
General Notices
•Consistently make multiple backup copies of your data for your protection. Hard disk drives

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 with a small stripe size offers similar performance.
RAID 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 arrays.
RAID MANAGEMENT
The Rocserve 4RTe can implement several different levels of RAID technology. RAID levels
supported by the Rocserve 4RTe 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
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
Preparing the and Powering 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.
. 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.
