SOHO RAID1

Chapter 1 Introduction
SR2000 SOHO RAID (Redundant of Array Independent
Drives) provides disk mirror function for the internal RAID
Level 1 for small offices or home offices. SR2000 SOHO
RAID is an excellent low-cost, high-efficiency substitute for
expensive RAID Level 5 and low-efficiency magnetic tape as a
back up.
1-1 Functions and Features
 The two hard disks can simultaneously perform mirroring
with synchronization.

One of the two hard disks can function as source, and the
other as target for back up purpose.

Providing on-line rebuild function.

Hot plug to replace damaged HDD without interrupting
system.

Support for IDE interface.

Alarm for HDD failure.
 System maintains normal performance when any HDD is
damaged.
 Supports most PC Operating Systems (OS), no drivers
required.

Hot plug to EIDE connector without interface card.

Compatible with most HDD.

LCD screen showing HDD operating status.

Status Indicator for HDD "reading" or "writing" modes.
 High power fan to prevent overheating.
 High quality stainless handle (SUS 302) for Removable
Carrier.

LINUX (RedHat Slackware, Debian, S.U.S.E.,
OPENLinux, TURBOLinux), Free BSD, IBM OS/2,
Solaris 2.x.
1-4 Note (Read carefully before using SR2000)
1. Use two identical hard disks (same brand name and model)
for optimum performance and greatest convenience.
2. To obtain optimum performance, use two brand new hard
disks or hard disks in perfect conditions without any
damaged sectors.
3. Use hard disks with a minimum capacity of 3.2GB Ultra
DMA 33/66.
4. Easy to use with hard disks manufactured by QUANTUM,
IBM, MAXTOR, or Western Digital. (see Chapter 6
Certified HDD for SR2000)
5. Whether it is the upper or lower deck, please set up both
Hard Disks in SR2000 to MASTER mode. (Drive Mode:
HDD Factory Default), or else HDD won’t be detected.
6. If replacing an old HDD with a new one, please purchase
the same brand and choose a disk capacity greater than or
equal to the original one.
7. SR2000 will automatically format a new HDD. No need to
use FDISK or FORMAT. Use the Auto-Rebuild Function
or manual Back Up to copy data to the new target HDD.
SOHO RAID4

8. Normal HDD mode for SR2000 is Ultra DMA. In the
event of failure to work with EIDE connector, HDD will
automatically configure itself in PIO mode 4 or with lower
speed.
9. There is a 6mm Ball Bearing Fan integrated in the SR2000
to prevent overheating for 7200 rpm HDD. When two
7200rpm Hard Disks are installed in a very busy server,
we suggest adopting a PC case with optimal design for
overheating prevention in order to avoid PC or RAID
crashes.
10. In case of power failure during the Auto-Rebuild
Function, controller will remember the rebuilding
progress percentage and carry on the operations when the
power is restored.
11. In case of power failure during Back up, restart Back up
when power is restored.
12. Under normal conditions, set Operation Mode Switch to
NORMAL position, or else your PC will not detect the
SR2000 and it will have to be reset.

Chapter 3 RAID Use
 After proper installation, the SR2000 can be considered
as one HDD.

Both FDISK and FORMAT commands have the same
function on the two Hard Disks inside the SR2000.

Some OS can perform self partitioning and formatting
without going through the above mentioned process.

After turning PC power on,SR2000’s two hard disks
maintain synchronized operation unless one of them stops
working.

3-2 Installation
 Installing two new Hard Disks in Auto-Rebuild mode
1. Push the switch on the right side center of the SR2000
to open its front panel. (Refer to Section 2-3 How to
open/close the front panel)
2. Insert two Removable Carriers into the SR2000. (HDD
assembled) (Refer to Section 2-4 How to remove/insert
the Removable Carrier.)
3. For handling convenience, open the panel as wide as
possible. Set Operation Mode Switch to NORMAL on
the upper right corner of controller.
4. Turn the power on. In the BIOS setting screen, change
HDD type to AUTO. This will enable the computer
system to automatically detect the type and model of
your Hard Disks.
5. After restarting the computer, the SR2000 will
SOHO RAID14

automatically format HDD synchronously. In addition,
it will install the OS and other required software.
(Refer to OS Installation Guide)
6. When the two installed hard disks have different
capacities, SR2000 will auto detect and set the capacity
according to the smaller one. This way your Computer
will suppose that the SR2000 has a smaller capacity.
 Installing one new HDD inAuto-Rebuild mode
1. Locate the original HDD in either the upper or lower
deck of SR2000.
2. In the event of no HDD inside, SR2000’s buzzer begins
to sound after computer is started. To switch off the
alarm, use a sharp pointed object to turn off the buzzer
on the front panel. TheAccess LED on the lower part
of the panel will be on. (Note 1)
3. After loading the OS, insert the Removable Carrier with
the new HDD into the upper or lower deck of the
SR2000. The capacity of the new HDD should be equal
to or greater than the original one.
4. Wait a few minutes, after which the SR2000 will
automatically perform the Auto-Rebuild function.
(Refer to Chapter 4Automatic Rebuild Function).
5. After the Auto-Rebuild, use a sharp pointed object to
turn on the buzzer on the front panel. TheAccess LED
on the lower part of the panel will be off. (Note 2)
 Hot plug and data on-line rebuild
1. In the event of any installed HDD’s operation failure,
the SR2000 buzzer will sound. Pull out the Removable
Carrier together with the damaged HDD without
turning the power off.
2. PC will continue normally to store data into the other
HDD; no data loss will happen.
SOHO RAID15

3. First follow the reverse order of the steps described in
Section 2-5 Installing HDD in Removable Carrier to
remove the damaged HDD, and then replace it with a
new HDD.
4. Insert the Removable Carrier with the new HDD into
the SR2000.
5. Wait a moment. The SR2000 will automatically
perform rebuild function on the new HDD. (Refer to
Chapter 4 Automatic Rebuild Function)
6. Use a sharp pointed object to turn on the buzzer on the
front panel. TheAccess LED on the lower part of the
panel will be off. (Refer to Note 2).
7. After the rebuild process is over, any data on the newly
installed HDD will be overwritten.
Note1：Alarm functions when buzzer switch is "On".
Note2：Buzzer access LED displays red when buzzer
switch is "Off".
SOHO RAID16

Chapter 4 Automatic Rebuild Function (A.R.F.)
 A.R.F. supports Windows NT4.0 Server & Workstation,
Windows 98*/95*/3.1X, Dos 6.22, SCO UNIX System V,
Linux (RedHat, Slackware, Debian, S.u.S.E., OPEN,
Turbo), Novell NetWare** V3.12, V4.1X, V5.X.
 In most OS, the A.R.F. is performed in the background in
order to restore rapidly a HDD to its normal read/write
operation.
 When the A.R.F. runs under Windows 95/98 during active
DMA, if mouse operation or foreground response should
slow down, please close the DMA and start the A.R.F.
once again.

Please choose optimal hardware and SR2000 compatible
OS. (Refer to Chapter 6 Certified HDD for SR2000).

Please set Operation Mode Switch to NORMAL position
on the control panel before use.

The HDD on the upper deck is designated as the Primary,
the one on the lower deck as the Secondary.
SOHO RAID17

4-1 Installing an extra HDD for rebuilding
 While the HDD with data is on the upper deck of the
SR2000, start the computer. The computer will
automatically detect the HDD on the lower deck of the
SR2000. In case of abnormal operation, the buzzer will
sound and the LCD will show the following:
1. Insert a new HDD correctly on the lower deck of the
SR2000. Screen will display and buzzer will sound in
case of abnormal operation. If the HDD is properly set
up, the LCD will show the following:
Pri HDD：OK
Sec HDD：Fail
Pri HDD：OK
Sec HDD：OK
2. A few seconds later, the LCD will show:
The data in the upper deck’s HDD will be rebuilt in the
lower deck’s HDD.

While data is in the HDD on the upper deck of the SR2000,
start up the computer. The computer system will
automatically check the status of the HDD on the upper
deck of the SR2000. In case of failure, the buzzer will
sound and the LCD will show the following:
Pri HDD：Fail
Sec HDD：OK
1. Set up a new HDD on the lower deck of the SR2000. If
the HDD is properly set up, the LCD will show the
following:
