Installing/Replacing the Hard Drives in the RAID System
Install an HDD by completing the following steps. After installing the HDD, install
required software if any.
1.
Lift the quick HDD release lever to release the selected HDD tray from the
desired drive bay.
2.
Slide the HDD tray out of the drive bay.
Note: After lifting the lever, the HDD tray will typically be easily released by the drive
bay. Due to the design tolerance of the SATA HDD connector, however, the HDD
tray may not always be released from the drive bay easily, or may not be released at
all. If this occurs, carefully slide the HDD tray out of the drive bay after lifting the quick
HDD release lever.
3.
12
When removed the HDD tray appears as shown below.
4.
13
Carefully slide the HDD into the drive tray.
5.
Ensure that the interface connectors are oriented toward the rear of the drive
tray.
Data & power
connectors are
on this side.
6.
14
Locate the screws included in the package. Ensure that the screw guides on the
side of the HDD are aligned with the openings on the side of the drive tray.
Fasten the HDD to the drive tray by inserting and tightening the screws.
7.
Align the drive tray with the guide rails and slide it into the drive bay. Ensure that
the tray is completely inserted and that the interface connectors are properly
seated.
8.
The RAID System is ready for connection to a host.
15
Connecting the RAID System to a Computer
Complete the following steps to connect the enclosure to a host computer.
1. Connect the AC/DC power adapter.
2. Insert the connector of the eSATA, USB 2.0, or FireWire 800 cable into the
corresponding port of the RAID System.
16
3. Insert the connector of the eSATA, USB 2.0 or FireWire 800 cable into the
corresponding port of a host computer.
Computer
Note: Due to compatibility issues, the Silicon Image eSATA host controller is highly
recommended for the eSATA/USB 2.0 model.
4. Turn the power switch to the on position.
17
5. When connected the System LED lights steadily orange.
Note: The RAID System should only be connected to a host computer via one
interface. Connection of the system to a computer via two or more interfaces
simultaneously is not recommended.
You are now ready to begin using your RAID System.
Safe Removal of the RAID System
eSATA/USB 2.0 model
The host, depending on the eSATA controller, may handle external eSATA HDD
devices as internal HDD devices, if so, safe removal of the RAID System from the
host is unnecessary.
USB 2.0 and USB 2.0/FireWire 800 models
Most current USB and 1394b host controllers handle USB and 1394b devices as
external devices; thus, it is highly recommended that the RAID System be safely
removed from the host.
18
Setting the RAID Mode
Deleting the current partition prior to changing RAID modes is highly recommended.
eSATA/USB 2.0 model
Due to the chipset of the eSATA/USB 2.0 model, after deleting the current partition
and setting the new RAID mode, the reset button on the right side of the Mode switch
must be pressed in order for the updated RAID mode to take effect.
Pressing the reset button on first use of the RAID system is highly
recommended.

Rebuild and Hot Swap Functions
Rebuild
In Mirror mode, if one of the HDDs fails and is replaced with a functional HDD, the
RAID System will automatically rebuild the target HDD (the new functional HDD) with
data from the source HDD (the remaining functional HDD) sector by sector. After the
rebuild is complete, data in both HDDs will be identical. The use of two identical
HDDs from the same manufacturer, having the same capacity and RPM is
highly recommended.
Online Rebuild vs. Offline Rebuild
In most cases, Rebuild refers to “Online Rebuild”, meaning the rebuild is initiated
when the RAID System is connected to the host. Due to the chipset, some systems
also support an Offline Rebuild function. After an Online Rebuild is activated and the
RAID System rebuild begins, even if the RAID System loses connection to the host,
the rebuild continues. If the RAID System is powered off, the RAID System will retain
the rebuild status in memory. When the RAID System is powered on again, the
rebuild process will resume from the previous status. If the Online Rebuild is not
activated initiating the rebuild, the RAID System cannot be rebuilt when not
connected to the host.
Rebuild Type by RAID System
eSATA/USB 2.0 Model - Online Rebuild
USB 2.0 Model - Online Rebuild
USB 2.0/FireWire 800 Model - Online/Offline Rebuild
Rebuild Existing Data to a Backup HDD
Due to the Rebuild behavior, the first HDD inserted into one of the HDD trays and
recognized by the RAID System becomes the source HDD. To rebuild existing data
from a source HDD to a backup HDD (target HDD), the source HDD must first be
inserted into one of the two HDD. After the host detects the source HDD (in 10 to 15
seconds), and the RAID System indicates the target HDD tray is empty via the LED
disk error light, the target HDD should then be inserted in the other HDD tray. The
RAID System will then recognize the target HDD, the disk error LED will stop, and the
rebuild process will begin automatically. These actions ensure that the RAID System
recognizes the correct source and target HDDs and to prevent the source data from
being overwritten.
Rebuild Speed
eSATA/USB 2.0 Model – 100 GB/hour or 28.4 MB/sec (approximate)
USB 2.0 Model and USB 2.0/FireWire 800 Model – 100 GB/hour or 28.4 MB/sec
(approximate)
Note: Because the chipset is processing rebuild task, if the data is accessed during
this period, the speed of data access of the USB 2.0 Model and USB 2.0/FireWire
23
800 Model is around 2 ~ 3 MB/sec; thus, access the HDD of these models during a
rebuild is not recommended.
Hot Swap
Hot Swap refers to the ability to add or remove a device from the host computer
without first powering off the device. After adding or removing the device, the
operating system automatically recognizes the change. Due to the chipset, hot swap
support varies by RAID System model.
Note: Because Span/Stripe mode combines two drives into a single logical unit, hot
swapping hard drives will halt RAID function. Hot swapping is not recommended in
Span or Stripe modes.
eSATA/USB 2.0 Model
The eSATA/USB 2.0 model supports HDD hot swap in JBOD and Mirror modes. Hot
swapping the HDD when the other HDD is transferring data when connected via
USB2.0 in JBOD mode is not recommended. When one HDD is hot swapped in
JBOD mode, the system will reset interrupting data transfer and causing data loss.
USB 2.0 Model
The USB 2.0 model does not support HDD hot swap in JBOD or Mirror modes.
Ensure that the RAID System is powered off before replacing HDDs.
USB 2.0/FireWire 800 Model
The USB 2.0/FireWire 800 model supports device HDD hot swap in JBOD and Mirror
modes. Hot swapping the HDD when the other HDD is transferring data is not
recommended in JBOD and Mirror modes. When one of the HDDs is hot swapped,
the system will reset interrupting data transfer and causing data loss.
24
RAID System and RAID Modes
A Redundant Array of Independent (or Inexpensive) Disks (RAID) is a system that
utilizes multiple hard drives to share or replicate data among the disks. The benefit,
depending on the selected RAID Mode (combinations of disks), is one or more of
increased data integrity, fault-tolerance, throughput or capacity when compared to
single drives.
Striping
Striping (RAID 0) is a performance-oriented, non-redundant data mapping technique.
It combines multiple hard drives into a single logical unit. Instead of seeing several
different hard drives, the operating system sees only one large drive. Striping splits
data evenly across two or more disks simultaneously, dramatically increasing
performance.
Striping can be implemented in disks of differing sizes, but the storage space added
to the array by each disk is limited to the size of the smallest disk. For example, if a
220 GB disk is striped with a 200 GB disk, the size of the array will be 400 GB.
Striping is typically used for high performance applications, such as, video editing,
video playback, and 3D multimedia design. Although Striping is an easily
implemented, simple configuration, Striping should never be used for mission critical
applications. In Striping mode, if one disk in the RAID System fails, all data in all
installed disks will be lost.
25
Spanning
Spanning provides another maximum capacity solution. Spanning combines multiple
hard drives into a single logical unit. Unlike Striping, Spanning writes data to the first
physical drive until it reaches full capacity. When the first disk reaches full capacity,
data is written to the second physical disk. Spanning provides the maximum possible
storage capacity but does not increase performance.
Mirroring
Mirroring (RAID 1) consists of at least two drives storing duplicate copies of the same
data. In this mode, the data is simultaneously written to two disks. Thus, the storage
capacity of a two-disk array is combined into a single disk and the capacity is limited
to the size of the smallest disk. In Mirroring mode, identical HDDs of the same
capacity and RPM from the same manufacturer are highly recommended for best
capacity utilization.
26
Mirroring offers the highest level of data protection. If one disk in the array fails, a
backup is always available. Mirroring is typically used in mission-critical systems,
such as payroll, accounting, and ERP databases.
JBOD
Just a Bunch of Disks (JBOD) refers to a group of hard drives. In JBOD, the number
of logical drives is equal to the number of physical drives. This mode allows the
RAID System to operate as a multi-disk storage enclosure but provides no data
redundancy.
