CHAPTER

1

Overview

Introduction and Requirements

The Overland Storage REO 4600 disk-based backup and recovery appliance (Figure 1-1)
with Protection OS® software delivers volume and device virtualization, management,
and connectivity capabilities, plus offers both iSCSI and Fibre Channel (FC) connectivity
features.

Figure 1-1: REO 4600 Disk Backup and Recovery Appliance

The VTL uses a Web-based interface and can be easily configured as either a virtual tape
library (VTL) and/or any mix of standalone virtual tape drives, Dynamic Virtual Tape
(DVT) drives, or virtual disks. Using DVT, users can create virtual tape cartridges that
automatically expand or shrink as needed to match the exact capacity requirements of the
backup operation.

The REO 4600 offers optional add-on data compression hardware that provides high
performance compression and decompression capabilities for use with any virtual tape
device. It provides 2:1 or better compression without sacrificing performance.

NOTE: Hardware compression is only available for virtual tape drives; it is not an available option

for disk targets.

Once the hardware card is installed, compression is enabled and is available for all virtual
tape devices on the REO 4600. The also implements in-band host application enable or
disable requests, and monitors the compression status for the virtual tape devices.

NOTE: Hardware compression settings cannot be changed manually.

Reviewing Pre-Installation Requirements

Before attempting to operate the REO 4600 with your backup media servers, verify that
your network meets the minimum requirements specified in the following sections.

10400253-101 01/2010 ©2007-10 Overland Storage, Inc. W 1-1

REO 4600 User Guide Introduction and Requirements

Network

For best results, Overland strongly recommends that you use a dedicated GbE network to
share the storage resources on the REO 4600 among multiple backup media servers.

To ensure optimum performance, always use the appropriate patch cables to connect the
REO 4600 to the backup-server storage network. To select the appropriate cables, use the
following guidelines:

• If you intend to use GbE, you must use Category 5e (or better) cables for GbE

connections. You can use either straight-through or cross-over cables.

• If you intend to connect the REO 4600 to a 100BASE-T or faster network, use

Category 5 (or better) shielded cables.

• The maximum length of cable for any Ethernet-based network connection is 328 feet

(100 meters).

NOTE: For smaller environments, you can attach the REO 4600 directly to a single application or

backup server by using standard Category 5e cables without the use of a switch.

Initiators

Initiators are required to communicate with the REO 4600 targets (devices). Each backup
media server that will interface with the REO 4600 must be equipped with a software- or
hardware-based initiator. The REO 4600 supports any computing platform with an
available iSCSI initiator, either in software or using an iSCSI HBA (it must comply with
iSCSI draft 20, version 1.0).

Browser

The REO 4600 GUI is a Web-enabled program that requires the use of cookies, Java
applets, and JavaScript. Make sure that the Web browser you use is configured to allow
these items.

REO 4600 User Guide Hardware Setup

Installation Preparation

CAUTION: Overland strongly recommends that you install the unit in a clean, air-conditioned

environment with power conditioning and an adequately rated uninterruptible power supply
(UPS). The unit is intended to be grounded.

Unpacking the REO Appliance

The REO 4600 appliance ships with up to twelve disk drives assembled into carriers and
packaged separately.

An Accessory Kit is included containing:

• Power cords

• Rack kit and adaptors

• REO 4600 Quick Start Guide

• REO 4600 Documentation CD

IMPORTANT: Before unpacking the unit, ensure that the area is free from conditions that

cause electrostatic discharge (ESD). Discharge static electricity from your body by touching a
known grounded surface. Also, avoid touching pins, leads, or circuitry.

Installing the Rail Kit

Your REO 4600 appliance comes with a set of slide rails for mounting the chassis in the
19-inch rack. The unit has a 2U form factor.

Each rail assembly consists of three rail members (Figure 2-2 on page 2-3). The inner
member is released from the rail assembly and attached to the appliance. The expandable
outer member along with the embedded middle member is mounted onto the rack.

The rail kit included with the appliance is adaptable for installation in the three major
types of hardware racks:

• Squared-holed RETMA rack on page 2-4

• Round-holed RETMA rack on page 2-4

• Round/Threaded-holed RETMA rack on page 2-5

NOTE: The two-post telco-style rack or a rack less than 32-inches in depth will not support the

REO 4600 appliance.

WARNING: Install multiple units in the rack from the bottom up. Extending a unit that has
empty spaces beneath it might cause the rack to tip and cause injury or damage. Overland
recommends that two people be used to insert or remove a unit.

The rails are not universal. They are stamped LH (left) and RH (right) and must be
mounted on the appropriate side (when facing the rack front).

CHAPTER

Powering Up the Appliance

3

The main steps involved in enabling power to the REO 4600 include:

• Making sure that the disks are correctly inserted in the appliance.

• Connecting the power cords to a power source and enabling power.

• Shutting down the appliance.

• Using an Uninterruptible Power Supply (UPS).

Disk Insertion Verification

IMPORTANT: The REO 4600 head unit must be fully populated with drives that are all of the

same capacity. Also, expansion units must be fully populated with drives that are all of the
same capacity. The drives in one unit can be a different capacity than those in other units as long
as all the drives in a single unit are the same size.

Make sure that the disks are seated correctly to prevent an error state during the power­on procedure.

Enabling Power

IMPORTANT: Both power cords must be connected. If one of the cords is disconnected or

malfunctioning, the appliance beeps continuously until the situation is resolved. Overland
recommends that you use separate power mains for the power sources.

Power problems can be the cause of serious failures and downtime on your network.
Ensure that the power input to your system is clean and free from sags and surges to avoid
unforeseen network outages. Overland strongly recommends that you install power
conditioning and an adequately rated uninterruptible power supply (UPS), especially in
areas prone to blackouts, power dips, and electrical storms.

The REO 4600 is intended to be grounded. Ensure it is connected to earth ground during
normal use.

Power Supplies

Each of the two power supply modules contain:

• A socket for an AC line cord.

• A two-color LED for indicating the status of the power supply.

• When all outputs are available, the LED becomes green.

• If the power supply fails, the LED becomes red.

• A latch for releasing the power supply.

• A handle for pulling the power supply out of the appliance.

• A pair of fans to prevent overheating.

• A feature that verifies the following (if not detected, an alarm signal sounds):

• All output voltages V1 to V5 are within regulation.

• The fans are operating normally.

• The internal temperature of the power supply is normal.

Figure 3-1: Enabling Power to the Appliance

CAUTION: To power on a REO system with an expansion unit, refer to Chapter 8, “Expanding

Capacity.” If you do not complete these steps in this order, the appliance might start in an

error state.

To power up the appliance:

1. Plug the UPS power cord into a separate AC power source and turn the UPS ON.

IMPORTANT: If power is automatically enabled when you attach the UPS cord to an AC
power source, shut down the appliance by pressing the Power button for one second

and then releasing it before continuing with the setup process.

2. To power up the REO 4600, press and hold the Power button for about one second,

which starts the power-up sequence.

The power switch is located in the lower-left corner of the front panel. The power
switch is a momentary contact device that needs to be held no more than one second
to begin the power-up sequence.

Figure 3-2: Power Button Location

After you turn the power on, the REO 4600 performs a power-on self-test (POST)
process. Following successful completion of the POST, which takes several minutes,
you should hear 3 beep tones spaced about 1 second apart.

If you are unable to hear the tones in your physical environment, wait about five
minutes before continuing.

IMPORTANT: On startup, the appliance might reach an error state and begin an

endless loop of alerts. The pattern (2 beeps separated by a 1-second delay) repeats
every 4 seconds. If this occurs, turn the appliance off and then back on. For more
information, see “Perpetual Loop of Audible Alerts on the Appliance” on page A-12

3. After you hear the POST completion beep tones, proceed to the configuration steps

outlined in the next chapter,

“Configuring Your Appliance” on page 4-1.

IMPORTANT: You must leave the appliance ON while completing the configuration

process for your application and backup media servers.

Shutting Down the Appliance

IMPORTANT: To ensure preservation of data on the REO 4600, you should not turn off the
appliance using the Power button. Always use the Shut Down option located in the GUI.

NOTE: If you are setting up a new appliance and you did not complete the steps in the proper

order or power was automatically enabled, you might not have access to the Shut Down
option in the GUI.

To shut down the appliance via the GUI:

1. Make sure none of the initiators (servers) have active connections.

To determine connection status, check the Initiator Summary page in the GUI.

2. In the GUI, click System > Maintenance.

3. On the Maintenance page, under Shut Down/Restart, click Shut Down.

4. When the confirmation message appears, click OK.

10400253-101 01/2010 ©2007-10 Overland Storage, Inc. W 3-3

REO 4600 User Guide Powering Up the Appliance

To shut down the appliance without GUI access:

1. Press and release the Power button on the front of the appliance quickly (1 second

or less) to initiate a graceful software-system shut down process.

2. Wait up to 1-2 minutes to see if the appliance responds.

The power LED turns off after the shutdown process is finished.

3. If the appliance does not shut down after the first attempt, repeat

Steps 1–2 a second time.

CAUTION: Pressing and holding the Power button for 4 seconds or more causes an

immediate hardware shut down that might result in the loss of data on the appliance if there
are any active read-, write-, or management-operations. Whenever possible, turn off the
appliance using the GUI or the graceful shutdown method described earlier. If you must use
the immediate hardware shutdown method, make sure that you first stop all host and
management server-related activity.

Backup Power

In order to protect your data from loss due to sudden power interruption, your REO 4600
supports the use of an external UPS. The unit monitors the UPS via the USB port
(reporting the charge level on the System Summary page). When the REO 4600 senses a
low UPS power condition, it initiates a graceful shutdown that completes before the UPS
runs out of battery power.

UPS Power Monitoring

When the REO appliance detects that it is connected to a UPS, it displays the UPS
Information (

Figure 3-3) at the bottom of the System Summary page.

Figure 3-3: System Summary Page UPS Information

• When the REO is receiving power from the main AC source, the indicator bar is

green. A complete green bar and 100% indication mean that the UPS battery is fully
charged.

10400253-101 01/2010 ©2007-10 Overland Storage, Inc. W 3-4

REO 4600 User Guide Powering Up the Appliance

• When the main AC power is interrupted and the REO is powered by the UPS, the

indicator bar turns red (Figure 3-4). The red bar and the numeric indication grow
smaller as the UPS battery charge goes down.

Figure 3-4: REO Running on UPS Power

• When the primary AC power is restored, the indicator bar turns green. The green

bar and the numeric indication grow toward 100% as the UPS battery recharges
itself.

Behavior When Connected to UPS

A REO 4600 with a UPS works normally as long as the main AC power is supplied. When
the main AC power is interrupted and the REO 4600 detects battery power, it initiates a
graceful shutdown in such a way as to be completed before the battery power runs out.

Once initiated, the shutdown process continues to completion, even if the AC power has
been restored. Upon completion of the shutdown, and when the AC power has been
restored, the REO 4600 does not restart automatically. Use the Power button on the front
panel to restart the REO 4600.

Supported UPS Models

UPS support has been verified with the APC Smart-UPS 2200VA. Other UPS devices that
connect via the same driver can be found at:

Continue the configuration process by configuring the GbE data ports as described in the
next section,

“Configuring the GbE Data Ports.”

Configuring the GbE Data Ports

Data Port 1 and Data Port 2 are GbE data ports used for block-level data transport
between your backup media servers targets and the REO 4600. Data Port
Port

2 are fully interchangeable before configuration.

IMPORTANT: The Management Port is on the Management LAN. Use Data Port 1 and Data

Port 2 on separate subnets of the backup network. Data Port 1 and Data Port 2 each
requires an available static IP address within their respective subnets. The REO can also be
managed via either of the data ports. Entering either data port IP address in your browser displays
the REO 4600 GUI.

The backup media servers must have a GbE port. If you have one or two backup media
servers, you can connect each one directly to one of the data ports on the REO 4600. If you
have more than two backup media servers, you must make these backup media server
connections through a GbE switch.

NOTE: You cannot configure the data port to which you are currently connected. When you are

connected to Data Port 1 via the default IP, you can only configure the Management Port.
To configure Data Port 1, you must be connected to the Management Port.

1 and Data

To configure the GbE ports:

1. At the System tab, click Network Configuration.

Because you are accessing the GUI through the Management Port, those port
options are not changeable.
