Overland Storage REO 9000 with ProtectionPAC Software

8 X Contents

Preface

The Overland Storage REO 9000 Disk-Based Backup-and-Recovery Appliance takes the lag time, expense, and burden out of backing up critical data and works seamlessly within current storage environments. The REO Appliance performs faster than traditional disk-based storage methods and serves as a shared network resource by utilizing highcapacity disks, high-speed Ethernet and Internet SCSI (iSCSI) connectivity, and unique software intelligence capability from Overland Storage.

The REO Appliance comes with a standard software package called the ProtectionPAC. The ProtectionPAC software contains all the basic features that you need to configure your REO Appliance to work within your network environment.

This document includes information that helps you set up the REO Appliance, including system requirements, questions that you need to answer before installing the product, and installation procedures.

Important: If you purchased multiple units, set up (attach and

configure) one unit at a time. The target names must be unique within a network; that is, if you are using multiple appliances, you must change the default target names.

Also, be aware that the keys are not interchangeable and Overland strongly recommends that you make a backup copy of the files on the keys before and after you configure them.

10 X Preface

Reviewing REO 9000 Concepts

CHAPTER

and Requirements

The main steps involved in preparing to set up the REO Appliance include:

Step 1 Understanding the concepts of iSCSI, Fibre Channel (FC), disk-to-disk-

to-tape (D2D2T) backup, redundant array of independent disks (RAID), tape emulation, logical volume management (LVM), and how the REO Appliance fits into the picture.

Step 2 Reviewing the requirements that your servers and network must meet to

ensure successful installation and operation of the REO Appliance.

Important Concepts to Understand

To understand the configuration of the backup network and how it fits into the local-area network (LAN) or Fibre Channel (FC) storage-area network (SAN), review the following sections.

Internet SCSI (iSCSI) Protocol

Internet SCSI (iSCSI) is a standard protocol for universal access to shared storage devices over standard, Ethernet-based transmission control protocol/Internet protocol (TCP/IP) networks. The connectionoriented protocol transports SCSI commands, data, and status across an IP network. For more information, see Glossary and Acronym List on page 163.

iSCSI Architecture

The iSCSI architecture is based on a client-server model. The client is a host system that issues requests to read or write data. iSCSI refers to a client as an initiator. The server is a resource that receives and executes client requests. iSCSI refers to a server as a target.

File servers, which store the programs and data files shared by users, normally play the role of server. With the REO Appliance, the application and backup servers within your network act as clients or initiators and the REO Appliance acts as a server or target. The initiators can either be software drivers or iSCSI host bus adapters (HBAs) on the server that is being backed up.

Reviewing REO 9000 Concepts and Requirements W 11

Overland Storage REO 9000 with ProtectionPAC Software

Fibre Channel (FC)

Instead of, or in addition to, using iSCSI and the TCP/IP protocol to transmit information over a network, you also have the option of using a SAN that makes use of the FC and Small Computer System Interface (SCSI) protocols. The FC protocol uses two additional protocols to communicate at the hardware level: Fibre Channel Arbitrated Loop (FCAL), which communicates with hubs, and Fibre Channel Switched (FCSW), which communicates with switches. The SCSI protocol provides the communication link at the higher level, between the hardware and the software.

You can use all three basic FC SAN topologies with the REO Appliance:

 Point-to-point. This topology provides a direct connection between

two N_Ports.

 Arbitrated loop. In an arbitrated loop, NL_Ports and FL_Ports are

daisy-chained with hubs, which means that only one device can send data at a time.

 Switched fabric. Switched fabric consists of one or more switches

that are interconnected, and multiple nodes connected to the switches.

The REO Appliance supports the following types of ports for FC:

Port Type Represents Associated Topology

N_Port Node Port Connects point-to-point or to F_Port

NL_Port Node Loop Port N_Ports that can connect to an arbitrated loop

FC uses strict naming conventions to support unique, 64-bit names for the worldwide node name (WWNN) and the worldwide port name (WWPN). These names are pre-assigned by the manufacturers of the different hardware components used in an FC.

12 X Reviewing REO 9000 Concepts and Requirements

Disk-to-Disk-to-Tape (D2D2T) Backup Capabilities

The REO Appliance is a storage resource used by a single backup server or shared by multiple backup servers using an Ethernet or FC network. By using standard backup software, you can copy backup data that resides on the REO Appliance to tape for long-term data retention.

The following illustration shows application servers sending backup data over a 10/100 or Gigabit Ethernet (GbE) LAN to backup servers sharing REO Appliance D2D storage over GbE or FC.

Redundant Array of Independent Disks (RAID)

RAID provides convenient, low-cost, reliable storage by saving data on more than one disk drive simultaneously. If one disk drive in a RAID 5 configuration becomes unavailable, the others continue to work in a degraded state, thus avoiding downtime for users.

Tape sub-system

Note: Because RAID 5 is designed for data protection, you might see

performance degradation when compared to JBOD operations.

RAID allows you to group the individual disk drives on the REO Appliance into logical disk drives of different sizes. You can configure your REO Appliance to create two physical RAID volumes by selecting either of the following RAID options:

 RAID 0. This configuration uses striping, which provides enhanced

performance and volume-level capacity. It divides the data into blocks and writes each block to a separate disk drive, which improves performance by dispersing the input and output load. RAID 0 does not provide data redundancy.

 RAID 5. This configuration uses striping and distributed parity,

which provides a balance between performance and availability. In addition to dividing the data into blocks as described for RAID 0, the parity information is also striped across the disks. If one of the disk drives fails, you can use the parity information to rebuild the lost data.

In addition to using either of the preceding RAID configurations, you can also take advantage of logical volume management (LVM) and create logical volumes from the data pool.

Important Concepts to Understand W 15

Overland Storage REO 9000 with ProtectionPAC Software

If you use a RAID 5 configuration, you can also set aside a disk drive for each physical host (controller); that is, you can create a hot spare. These disk drives remain in standby mode, and you can use them immediately if another disk fails.

Tape Emulation

The ProtectionPAC software includes two tape emulation features, which you can use to create virtual linear tape-open (LTO-2) tape devices that provide 2-to-1 compression ratios with typical data sets (actual performance might vary with application). When you use tape emulation, the disk drives on the REO Appliance appear to your backup software as LTO-2 tape drives, which simplifies the setup process while simultaneously providing data compression and the attributes of backing up data to disk.

Depending on the configuration that you use, you get a different number of virtual LTO-2 devices. In the just-a-bunch-of-disks (JBOD) configuration, you can have up to 24. If you use RAID 0 or 5 without logical volumes, you can have four. If you use logical volumes with RAID 0 or 5, you can create up to 64 virtual LTO-2 devices.

If you decide to use tape emulation, you also have the option of using fixed-length (Tape) or dynamic-length (Dynamic Tape) devices. To take advantage of the Dynamic Tape option, you must use logical volumes, which is described in the next section. Using Dynamic Tape lets you create devices that adjust to the size of individual backup jobs.

Logical Volume Management (LVM)

With LVM, you can combine the two physical RAID volumes into multiple logical volumes (partitions) of different sizes and assign logical unit numbers (LUNs) to represent the different volumes, or REO devices. This feature lets you set up and assign devices to different systems according to your needs and the configuration and type of storage network that you use.

Using this feature in the ProtectionPAC software, you can create up to 64 LUNs, and you can reassign space allocation for disk or standard (not dynamic) virtual tape devices, in 1 gigabyte (GB) increments, on the fly.

Reviewing Pre-Installation Requirements

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

Important: If you purchased multiple units, set up (attach and

configure) one unit at a time. The target names must be unique within a network; that is, if you are using multiple appliances, you must change the default target names.

Also, be aware that the keys are not interchangeable and Overland strongly recommends that you make a backup copy of the files on the keys before and after you configure them.

16 X Reviewing REO 9000 Concepts and Requirements

Network

Setup Guide

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

To ensure optimum performance, always use the appropriate patch cables to connect the REO Appliance 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 Appliance to a 100 BaseT network,

use CAT 5 (or better) shielded (screened) or unshielded 100-ohm twisted-pair RJ-45 network cables. Also:

 If you intend to connect the Management Port, which is a 10/100

port, to an application or backup server via a switch, you must use a straight-through cable.

 If you intend to connect the Management Port directly to your

application or backup server (without a switch), you must use a cross-over cable.

 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 Appliance

directly to a single application or backup server by using standard Category 5E cables without the use of a switch.

iSCSI Initiators

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

Reviewing Pre-Installation Requirements W 17

Overland Storage REO 9000 with ProtectionPAC Software

Setting the SCSI Time-Out Value in Windows Environments

If you intend to use your REO Appliance in a Windows environment, be aware that there are certain operating conditions in which time-out errors might occur. These errors usually result in the system reporting a disk failure for the associated REO Appliance disk drive or drives. (These errors might be reported as iSCSIPrt errors in the System Log of the Event Viewer. Examples include an Event ID 9 [Target did not respond in time for a SCSI request…] and Event ID 39 [Initiator sent a task management command to reset the target…]. Other symptoms might include “Lost Delayed Write Data” system error messages or similar error messages related to the REO Appliance disk drives.)

The reason that these disk time-out errors can occur is because the default I/O time-out value for Windows is 20 seconds, which is not sufficient to support the default iSCSI protocol time-out value of 60 seconds. When you install and set up your REO Appliance, Overland

strongly recommends that you set this value to 60 seconds.

To set the time-out value to 60 seconds

1 On the Windows system, run regedit.

Warning: If you edit the registry incorrectly, you might cause serious

problems that require you to reinstall your operating system. Edit the registry at your own risk. Prior to making any changes, refer to the

following Microsoft Knowledge Base article: http://support.microsoft.com/default.aspx?scid=kb;en-us;322755

2 In HKEY_LOCAL_MACHINE\System\CurrentControlSet\

Services\Disk, edit or add the TimeOutValue entry to set it to 60

seconds in decimal format ((0000003c in hexadecimal).

 To edit the value for the TimeOutValue entry if it already exists,

double-click the entry, enter the new value, and click OK.

 To add the TimeOutValue entry if it does not yet exist, right-click

anywhere in the list of values, and then click New > DWORD value. Name the new value TimeOutValue, and then double-click it to edit the setting.

Setting Up the REO 9000

The main steps involved in setting up the REO Appliance include:

Step 1 Unpacking the REO Appliance, and reviewing safety guidelines.

Step 2 If you intend to position the REO Appliance in a rack, attaching the

required components.

Step 3 Connecting the REO Appliance to the management LAN.

Step 4 Connecting the REO Appliance to the application and backup servers,

SAN for the backup servers, or FC.

Step 5 Connecting external SCSI devices.

Step 6 Attaching the power cords.

Preparing the REO Appliance

Caution: Due to the weight of each rack-mounted unit when it is fully

extended, you should install units from the bottom up. Extending a unit that has empty spaces beneath it might cause the rack to tip forward or might cause personal injury. Overland Storage recommends that two people support and slide the unit in the rack.

Vorsicht: Aufgrund des Gewichtes eines Gerätes, welches für den

Einbau in ein Rack gedacht ist, empfehlen wir Ihnen, dieses von unten nach oben in das Rack zu installieren. Wenn Sie ein Gerät aus dem Rack heraus ziehen, könnte es Ihnen entgleiten und so zu Verletzungen führen. Wir empfehlen den Ein- und Ausbau des Gerätes durch zwei Personen.

1 Unpack the REO Appliance.

The shipping container contains the following:

 Overland Storage appliance chassis

 Depending on which version of the product that you purchased, either

12 or 24 disk carriers and disk drives

 Power cords (U.S.) (Approved cord sets shall be used in countries

outside North America.)

 Appliance face-plate

 REO SoftKey

 Rack-mount hardware

 Documentation CD-ROM and poster

2 Review the following guidelines prior to positioning the REO Appliance

physically within your network.

 Make sure that the REO Appliance is accessible.

 Make sure there is unrestricted air flow around the unit and through

the vents in the sides and rear of the case.

 Route external cables so that they can be connected easily without

blocking air vents or impeding air flow.

 Protect the REO Appliance from extreme temperature and humidity.

Overland Storage recommends that you install the REO Appliance in a clean, air-conditioned environment where water and moisture cannot enter the case of the REO Appliance. Keep the air as free from dust as possible.

 Protect the REO Appliance from physical shock and vibration.

 Make sure that the inlet air temperature within the rack remains

below the specified limit of 95°F (35°C).

 Keep the REO Appliance and cabling away from sources of electrical

noise such as elevator shafts, stereo speakers, microwave ovens, air conditioning units, and even telephones. Electromagnetic fields can interfere with the signals on copper cabling and introduce errors, therefore slowing down the network.

Attaching the Power Cords

1 Attach all four power cords to the REO Appliance.

2 Plug the power cords in to an AC power source (do not turn the power on).

Important: You must connect and use all four power cords; if one of the

cords is disconnected or malfunctioning, the REO Appliance beeps repeatedly until the situation is resolved. Overland Storage recommends that you use separate power mains for the power sources.

If you are not using Dynamic Host Configuration Protocol (DHCP), it is critical to the configuration process that you refrain from enabling power to the REO Appliance before completing the configuration steps specified in the next chapter.

Power problems can be the cause of serious failures and downtime in your network. Ensure that the power input to your system is clean and free from sags and surges to avoid unforeseen network outages. Overland Storage 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 Appliance is intended to be grounded. Ensure it is connected to earth ground during normal use. Installing proper grounding helps to avoid damage from lightning and power surges.

Step 1 Making a backup copy of the key.

Step 2 If your network does not use DHCP, manually editing the configuration

and network files on the key.

Step 3 Connecting the key to the REO Appliance.

Understanding What the REO SoftKey Is

The REO SoftKey is a removable USB disk drive on a key ring. It contains the software and settings required for configuring the REO Appliance and must be inserted in the REO Appliance whenever you restart it (because the REO Appliance uses a Linux-based OS, the key is formatted using the virtual file allocation table [VFAT]). You can also use the REO SoftKey to download and install updates when they become available.

Important: If you purchased multiple units, note that the keys are not

interchangeable

The simplest configuration can be achieved when your LAN uses DHCP on its own subnetwork (subnet). If your LAN does not use DHCP, you must manually edit the configuration file located on the REO SoftKey before continuing.

Using the REO SoftKey to Start the REO 9000 W 31

Overland Storage REO 9000 with ProtectionPAC Software

Backing Up Your REO SoftKey (Pre-Configuration)

Make a backup copy of all the files on the REO SoftKey before and after you configure it.

1 Remove the cap from the REO SoftKey, and insert it into a USB port on

a Windows 2000, 2003, or XP system that contains active virusprotection software.

Note: If you have not previously installed a USB mass-storage device,

Windows displays a dialog box that indicates it has found new hardware and will automatically install the necessary drivers on your system.

2 Double-click My Computer on your desktop (or use Windows Explorer),

and browse to the software-key disk drive.

Overland Storage REO 9000 with ProtectionPAC Software

Verifying that the Gateway Address and Management Port are Correctly Configured

The Default Gateway is the IP address that provides entrance into the network to which the REO Appliance is assigned. The Management Port connects the REO Appliance to the management system, which you use for network management on the LAN.

Important: Remember that the Management Port and both Data Ports

must be on separate subnets.

1 Using the management system, access the mapped drive

\\REO\programs.

2 To open the REO Appliance console in your Web browser, double-click the

Overland.html file.

Tip: After you have initially configured your REO Appliance, if you are

not using DHCP, you can also access the interface by typing the IP address assigned to the Management Port for the REO Appliance.

To launch the console, double-click Overland.

52 X Configuring the Management System

3 If you are prompted for your name and password, enter the following in

case-sensitive format:

Logon Name: Administrator Password: system

The REO Appliance console appears.

Tip: To access online help on any of the pages in the console, click Help

under System Menu or click the Help button that appears on each of the pages.

To access help at any time, click Help.

Verifying that the Gateway Address and Management Port are Correctly Configured W 53

Overland Storage REO 9000 with ProtectionPAC Software

4 In the left pane, under System Menu, click Network Configuration.

Click Network Configuration.

5 If you are not using DHCP, in the Default Gateway section of the right

pane, make sure that the correct IP Address appears.

If DHCP is disabled, the IP address and other information is completed using information from the configuration file that you previously modified (for more information, see Editing the Configuration File (for a

non-DHCP or UNIX Management System) on page 33).

Verify that this is the correct information for your network.

54 X Configuring the Management System

6 In the Management Port section, verify the following:

 If your network uses DHCP (recommended), make sure that Enable

is selected. The Management Port is automatically configured when DHCP is enabled. This is the default setting. (If you are using DHCP, the system displays the addresses that are currently being used.)

 If your network does not use DHCP or you are using a UNIX-based

system, make sure that the correct addresses appear and that Disable is selected.

7 Continue the configuration process by configuring the GbE data ports as

described in the next section.

Configuring the GbE Data Ports

The GbE data ports are used for block-level data transport between your backup servers and the REO Appliance. Data Port 1 and Data Port 2 are fully interchangeable prior to configuration.

Important: Remember that the Management Port is on the LAN (a

10/100 network); use Data Port 1 and Data Port 2 on separate subnets of the backup network. Data Port 1 and Data Port 2 each require an

available static IP address within their respective subnets. If you want to manage the REO Appliance from the same port, use the GbE (Data Port 1 or 2) IP address. Entering this IP address in your browser displays the REO Appliance software console.

Setup Guide

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

To configure the GbE ports

1 In the right pane, scroll down below the Management Port section to

locate the Data Port 1 and Data Port 2 sections.

2 In the Data Port 1 section, enter the following:

 IP Address. Using dotted decimal notation, enter an available static

IP address that falls within the Data Port 1 subnet. An example of an address is: 192.168.1.4.

 Subnet Mask. Using dotted decimal notation, enter the subnet

address. An example of an address is: 255.255.0.0.

Tip: If you change one of these settings, such as the IP Address, you

might need to reconnect to the server via your Web browser.

Configuring the GbE Data Ports W 55

Overland Storage REO 9000 with ProtectionPAC Software

3 Click Apply.

4 Repeat these steps for Data Port 2 using an IP address that falls within

the Data Port 2 subnet.

Tip: Overland Storage recommends that you use a ping command to

ensure that the management system sees each port on the REO Appliance.

5 If you purchased the FC-enabled REO Appliance, continue the

configuration process by entering the FC information described in the next section; otherwise, proceed to the subsequent section, Entering the

System Information on page 57.

Entering the Fibre Channel Information

1 In the right pane, scroll down to the Fibre Channel Configuration

section.

2 For each FC port (the REO Appliance provides two), select the applicable

settings from the Set Link Speed and Set Link Topology lists.

 For link speed, select Auto, 1 GB, or 2 GB.

 For topology, select Auto, Fabric/Point-to-Point (N_Port), or Loop

(NL_Port).

Select the applicable settings for each Fibre Channel port.

3 Click Apply.

4 Continue the configuration process by configuring the system

information as described in the next section.

56 X Configuring the Management System

Entering the System Information

1 In the left pane, under System Menu, click System Configuration.

Setup Guide

Click System Configuration.

2 In the System Information section of the right pane, enter the

following:

 Workgroup/Domain Name. Enter the workgroup or domain name

assigned by your network administrator.

 REO Name. Enter up to 16 characters to name the REO Appliance.

You can use letters or a mixture of letters and numbers, and you can also use hyphens (-). Overland Storage recommends that you change this name (the default is REO), especially if you use multiple REO Appliances in your network.

 REO Description. Enter up to 20 alphabetical or numerical

characters (or a combination of the two) to describe the appliance.

Change these entries, especially if you use multiple appliances.

3 Click Apply.

4 Continue the configuration process by entering the logon information

described in the next section.

Entering the System Information W 57

Overland Storage REO 9000 with ProtectionPAC Software

Configuring Logon Information

Using the Logon Information section, you can change your logon name and password, which Overland Storage recommends that you do during the initial configuration process. If you choose to keep Administrator as your logon name, Overland Storage strongly recommends that you change the password to protect your network from unauthorized users.

1 In the right pane, scroll down below the System Information section to

locate the Logon Information section, and enter the following in case- sensitive format:

 User Name. (required) Enter a new logon name using up to 30

alphabetical or numerical characters or a combination of the two.

 Password. (optional) Enter a new password using up to 30

alphabetical or numerical characters or a combination of the two characters (do not use spaces or Ctrl-key characters).

 Retype Password. Enter the password again.

2 Click Apply.

3 Continue the configuration process by entering the e-mail information

described in the next section.

Configuring E-mail Alerts

The REO Appliance continuously monitors its performance and routinely checks for disk failures. If you use the messaging option, an e-mail is sent whenever the Status of a volume on the REO Device Summary page becomes anything other than Up (for example, changes to REBUILDING).

Tip: You can also use the ALARM MESSAGES section on the Physical

Volume Management page to see more information. The messages (also known as asynchronous event notifications) that appear on this page display additional information about each disk that might not be displayed in an alert e-mail.

You can specify whether the REO Appliance should send an alert once or repeat the message until the issue is resolved. Each alert that is sent reports the status of all volumes on the REO Appliance. If you configure the option to use an Alert Frequency of five minutes or more, the alerts will be numbered.

If your mail server is able to send e-mail messages outside the company, you can also set up messaging to notify Overland Storage Technical Support automatically whenever a critical error occurs.

58 X Configuring the Management System

Setup Guide

To configure messaging

1 In the right pane, scroll down below the Logon Information section to

locate the E-mail Notification section, and enter the following:

 Mail Address. Using dotted decimal notation, enter the IP address of

your incoming mail server.

 From Address. Enter the e-mail address from which the alert will be

sent. This address must use the same domain as the mail server specified for Mail Address.

 Address for all warnings & critical messages. Enter the e-mail

address to which alerts should be sent (for example, the e-mail address for the network administrator).

 Address for critical messages only. To instruct the REO Appliance

to notify Overland automatically whenever a critical message is presented, enter the following e-mail address:

techsupport@overlandstorage.com

Involved in the Backup Process

The main steps involved in configuring the backup servers include:

Step 1 Mapping the REO Appliance to a drive letter to simplify access to the

console and other installation and management tools.

Step 2 Installing software client drivers or storage adapters for iSCSI or FC

access.

Mapping a Network Drive to the REO Appliance (Windows Only)

To access the components used for installation and configuration of the REO Appliance, you must map a network drive from the system to a folder located on the REO Appliance.

1 Make sure that the REO Appliance is still powered on and that the REO

SoftKey is still inserted in a USB port.

2 Perform the steps previously outlined under Mapping a Network Drive to

the REO Appliance (Windows Only) on page 39.

3 Repeat these steps for each system that will access storage on the REO

Appliance.

Establishing Communication

If you are using iSCSI connectivity, iSCSI initiators are required to communicate with the iSCSI targets (REO Devices) on the REO Appliance. Each backup server that uses the REO Appliance must be equipped with a software initiator, such as the Microsoft iSCSI Software Initiator, or an IP storage HBA, such as the Intel PRO/1000 T IP Storage Adapter.

Note: You do not need TOE-equipped (Transmission Control Protocol

[TCP] Offload Engine) or special iSCSI-capable GbE HBAs to work with software initiators. Any standard Network Interface Card (NIC) can serve as an iSCSI network interface device; however, Overland Storage strongly recommends that you use GbE for enhanced performance.

If you are using FC connectivity, make sure that the applicable FC initiator is installed.

Creating Logical Volumes

The main steps involved in switching from one configuration to another or creating logical volumes include:

Step 1 Selecting the applicable configuration.

Step 2 Creating the desired number of logical volumes, and setting their size.

Using the Default Volume Setup

The REO Appliance uses a default volume configuration of RAID 5 with logical volumes. To use this configuration, you must create the logical volumes.

X To use the default configuration and create logical volumes, proceed to

Creating Logical Volumes on page 71.

Changing the Volume Configuration

You can use the Volume Setup feature in the console to select a different RAID configuration or to select the JBOD configuration.

Important: Be aware that the process of changing the volume

configuration takes time for the RAID 5 configurations while the arrays are initialized. After you select the new configuration and the initialization process begins, you can use the REO Appliance, but performance will be impacted. Overland Storage strongly recommends that you wait until the Status on the Physical Volume Management page is OK (not INITIALIZING) before using a volume. (Switching to a RAID 0 or JBOD configuration usually requires less than 10 minutes.)

5 After waiting approximately five minutes, log on to the console, and then

proceed to the steps outlined in Configuring REO Devices as Disk or Tape

Devices on page 73.

Selecting a RAID Configuration

The REO Appliance supports RAID 0 and RAID 5. You can only select one configuration; that is you cannot set up one volume to use RAID 0 and set up another to use RAID 5.

Important: Because the process of changing the volume configuration

takes time if you select a RAID 5 option, Overland Storage recommends that you make your selection and let the process run overnight. (Switching to a RAID 0 or JBOD configuration usually requires less than 10 minutes.)

In a RAID configuration, how the volumes are arranged depends on whether you are using an appliance that contains 12 physical disks or 24, and it depends on whether those disks are 250 GB or 400 GB in size.

The appliance also contains two physical hosts (controllers). If you are using 12 physical disks, they are all assigned to the first host; if you are using 24 disks, the second set of disks is assigned to the second host.

If you select a RAID 5 option, you will also have the option of creating a hot-spare disk drive for each physical host (controller) after you click Submit. (These disk drives remain in standby mode, so that you can use them immediately if another disk fails.)

Changing the Volume Configuration W 65

Overland Storage REO 9000 with ProtectionPAC Software

The following describes how the volumes are arranged in RAID configurations, depending on the number of disks and their size.

If you are using the 12-disk appliance:

 RAID 0. Creates three REO Devices. Each REO Device (physical unit

[PU]) is comprised of four disks. Each device provides either 1000 GB (using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity.

 RAID 5, without hot spare. Creates two REO Devices. Each REO

Device (PU) is comprised of six disks. Each device provides either 1250 GB (using 250 GB disks) or 2000 GB (using 400 GB disks) of capacity.

 RAID 5, with hot spare. Creates two REO Devices and one hot-spare

disk. One REO Device (PU) is comprised of six disks and the other is comprised of five disks. The five-disk device provides either 1000 GB (using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity, and the six-disk device provides either 1250 GB (using 250 GB disks) or 2000 GB (using 400 GB disks) of capacity.

If you are using the 24-disk appliance:

 RAID 0. Creates six REO Devices (three physical units for each host).

Each REO Device (PU) is comprised of four disks. Each device provides either 1000 GB (using 250 GB disks) or 1600 GB (using 400 GB disks) of capacity.

 RAID 5, without hot spare. Creates four REO Devices (two physical

units for each host). Each REO Device (PU) is comprised of six disks. Each device provides either 1250 GB (using 250 GB disks) or 2000 GB (using 400 GB disks) of capacity.

and Initiators

The main steps involved in associating targets (REO Devices) and initiators with each other include:

Step 1 Understanding how the targets and initiators must be identified so that

they can successfully communicate with each other.

Step 2 Making sure that IP addresses and names match on both the targets and

the initiators.

Step 3 Making another backup copy of the REO SoftKey so that your

configuration information is preserved.

Understanding How Initiators and Targets (Devices) are Connected

To configure the REO Appliance as a backup-and-recovery-acceleration appliance, you must provide target and initiator information. Each volume on the REO Appliance is a target (REO Device); the servers are initiators.

If you are using iSCSI initiators, an iSCSI name is required both at the targets and at the initiators. An iSCSI target name is required because it uniquely identifies a target as a storage resource for the initiators. An iSCSI initiator name is required because it helps identify an initiator for the purpose of target resource allocation (that is, which initiator has access to which target resource).

If you are using FC initiators, you must provide a WWNN and WWPN for the same purpose of providing a unique identifier.

Reviewing iSCSI Naming Conventions

iSCSI names must be unique within the domain of the end user. However, because user domains can potentially merge with other user domains, the iSCSI naming mechanism is structured to ensure worldwide uniqueness. To ensure both domain and worldwide name uniqueness, iSCSI provides for the use of different types of naming mechanisms, based on the naming authority. Each iSCSI name is prefixed with a short designator string that indicates the type of naming

Associating Targets (Devices) and Initiators W 87

Overland Storage REO 9000 with ProtectionPAC Software

authority. The iqn prefix is used for iSCSI-qualified names and the eui prefix is used for Institute of Electrical and Electronics Engineers (IEEE) iSCSI names.

To ensure the free movement of network HBAs between hosts without carrying over the SCSI state information, iSCSI initiator names are associated with iSCSI nodes instead of with network adapter cards. A target name should not be tied to hardware interfaces, which can be changed. A target name should identify the logical target and must be the same for the target, regardless of the physical portion being addressed.

iSCSI-Qualified Names

iSCSI-qualified names are constructed in four parts, each separated by a decimal. The first part of the name is the iqn prefix. The second part of the name is a date code in yyyy-mm format. The third part is a reversed domain name, and the fourth part is any string (within the character set and length boundaries) that uniquely identifies the initiator or target. For example, the iSCSI-qualified name iqn.2002-

07.com.mycompany.storage:drive1 can be broken down into four parts as shown.

Type Date Organization Naming Authority Subgroup Naming Authority

iqn 2002-07 com.mycompany storage:drive1

Note: To enhance ease-of-use, the REO Appliance uses more simplified

iSCSI target names.

IEEE iSCSI Names

IEEE iSCSI names are used when a manufacturer is already basing unique identifiers on worldwide names, as defined in the SCSI SPC-2 specification (ANSI [American National Standards for Information Systems], 2001. NCITS.351:2001. SCSI Primary Commands - 2 [SPC-2].). IEEE iSCSI names are constructed in two parts, separated by a decimal. The first part of the name is the eui prefix. The second part of the name is an EUI-64 address in ASCII hexadecimal (16 digits). For example, the IEEE iSCSI name eui.02004567A425678D can be broken down into two parts as shown.

Type EUI-64 Worldwide Name

eui 02004567A425678D

88 X Associating Targets (Devices) and Initiators

Reviewing How Targets (REO Devices) and Initiators are Associated

After you have named the targets and initiators (described later in this chapter), you must assign them to each other in pairs. This must be performed both on the REO Appliance by using the REO Appliance software console and on the application or backup server by using the iSCSI initiator management tools. The following illustrations demonstrate how this should be accomplished in an iSCSI configuration using the Microsoft iSCSI initiator.

1 Match the Data Port IP address on the REO Appliance to the

target address on the backup server.

For example, if Data Port 1 on the REO Appliance is assigned an IP address of 10.10.50.42, the IP address on the REO Appliance Network Configuration page must match the target address on the iSCSI configuration tool screens (you must launch the iSCSI configuration tool to obtain this information) for the backup server you are configuring.

Setup Guide

(To access this dialog box, double-click the Microsoft iSCSI Initiator icon on your desktop.)

Note: The preceding example illustrates using the Microsoft iSCSI

Configuration Tool.

(To access the Add Target Portal dialog box, click Add on the Target Portals tab in the iSCSI Initiator Properties dialog box.)

Overland Storage REO 9000 with ProtectionPAC Software

2 Verify that the iSCSI Target Name on the REO Appliance

matches the target name on the backup server.

For example, if one of the volumes on the REO Appliance is named idevice.name0, this is the iSCSI Target Name. The target name on the REO Appliance Device Configuration page must match the target name on the iSCSI configuration tool screens for the backup server you are configuring.

Important: The target names must be unique within a network. If you

are using multiple appliances, you must change the default target names. For more information, see Expanding Storage Capacity

(Scalability) on page 107.

90 X Associating Targets (Devices) and Initiators

3 Match the iSCSI initiator name on the REO Appliance to the

initiator name on the backup server.

For example, if one of the volumes on the REO Appliance is named idevice.name0, this is the iSCSI Target Name. You must assign at least one initiator to this target (if you do not, you will not be able to access the disk). The iSCSI initiator name on the initiator portion of the REO Appliance Device Configuration page must match the initiator name on the iSCSI configuration tool screen for the backup server you are configuring.

The Initiator IP Address field is optional. If used, both the iSCSI initiator name and the IP address will be checked by the REO Appliance and must match for access to be granted.

Setup Guide

Configuring Targets (REO Devices and External Devices) and Initiators

Each disk or LUN on the REO Appliance is an iSCSI or FC target and has a passive role in fulfilling requests initiated by the application or backup server.

The backup server is an initiator and plays the active role in issuing commands. An initiator is configured in conjunction with targets on the REO Appliance as an access control mechanism. You must configure an initiator by using the initiator software and by using the REO Appliance console. You can assign up to eight initiators (iSCSI, FC, or a combination of both) to each REO disk device (a virtual tape device currently supports only one initiator) or External Device.

3 In the iSCSI Initiator Name box, enter a unique name (up to 223

alphabetical or numerical characters) of an authorized initiator for the target.

Enter the unique name of the initiator, select the ID, and click Submit.

4 (Optional) In the Initiator IP Address box, if you want to use an

additional level of authentication, use dotted decimal notation to enter the IP address of the backup server.

If present, the IP address of the initiator is compared with the IP address you enter here.

5 From the REO Device ID list, select the ID for the target to which you

are assigning this initiator.

6 Click Submit.

7 Repeat step 2 through step 6 for each target.

Configuring the iSCSI Initiator with Target (External Device) and Initiator Assignments

X On each applicable server, use the management tool that came with your

iSCSI initiator to specify the target (External Device) information.

Backing Up Your REO SoftKey (Post-Configuration)

Make another backup copy of all the files on the REO SoftKey.

1 Transfer the REO SoftKey to a USB port on a Windows 2000, 2003, or XP

system that contains active virus-protection software.

2 If you are using Windows, double-click My Computer on your desktop

(or use Windows Explorer), and browse to the software-key disk drive.

The name of this disk varies based on your system configuration, but it will be called something like Removable Disk (G:).

3 Make a backup copy of all the data on the REO SoftKey, and store the

copy in a secure location.

CHAPTER

This chapter provides a few tips on working with the REO Appliance including:

 Logging on to the Web interface.

 Reviewing the information displayed in the REO Device Summary.

 Switching from one configuration to another.

 Understanding how disk drives are numbered.

 Powering down the REO Appliance.

Logging On from Any System with Network Access

After you have completed configuration of the REO Appliance, you can access the REO Appliance console from any system that has network access to the IP address of the Management Port.

1 Choose one of the following:

 If you are using DHCP, using the management system, access the

mapped drive \\REO\programs, and then double-click the Overland.html file.

 If you are not using DHCP, in your Web browser, type the IP address

assigned to the Management Port for the REO Appliance.

Tip: You can also use the IP addresses assigned to the Data Ports, which

you can do even if you are using DHCP.

2 When the prompt appears, type your name and password (the defaults

are

Administrator and system) in case-sensitive format.
