Preface

The Overland Storage REO 1000 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 Protection OS. The Protection OS 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, 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 1000 Concepts

CHAPTER

and Requirements

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

Step 1 Understanding the concepts of iSCSI, 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), 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 143.

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 1000 Concepts and Requirements W 11

Overland Storage REO 1000™ with Protection OS™ Software

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 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 Gigabit Ethernet (GbE) LAN to backup servers sharing REO Appliance D2D storage over GbE.

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.

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 a physical RAID volume 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.

Important Concepts to Understand W 13

Overland Storage REO 1000™ with Protection OS™ Software

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.

Tape Emulation

The Protection OS 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. The REO Appliance uses an InstantSearch feature that ensures you can recover any file in any directory in less than one second.

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 four. If you use RAID 0 or 5 without logical volumes, you can have one. 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 create 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 Protection OS 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.

Virtual Tape-Libraries (VTLs)

The VTL feature lets you create up to four virtual libraries on your REO Appliance that emulate a NEO SERIES tape library (NEO 2000, 4100, or

4200). The VTL appears as a standard physical library to your backup software. (If you already use a physical library in your backup process, this feature helps you integrate a disk-based backup solution into your existing environment.) It includes virtual versions of the storage elements (storage slots, also known as bins) and data-transfer elements (tape drives) that make up a physical library or changer.

To take advantage of the VTL feature, you must use a RAID configuration with logical volumes. Each virtual tape-cartridge is automatically defined for you by the REO GUI as a device of type Dynamic Tape, which means that it adjusts to the size of an individual backup job. (For more information, refer back to Tape Emulation.) You can create up to 180 virtual cartridges and 32 virtual drives.

14 X Reviewing REO 1000 Concepts and Requirements

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, 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.

Network

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:

 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 Category 5 (or better) shielded (screened) or unshielded 100-ohm twisted-pair RJ-45 network 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 Appliance

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

REO SERIES™ Setup Guide

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).

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.

REO SERIES™ Setup Guide

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

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

Step 1 Unpacking the appliance, and reviewing safety guidelines.

Step 2 If you intend to position the appliance in a rack, attaching the required

components.

Step 3 Connecting the appliance to the management LAN.

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.

Step 2 Choosing whether to change the settings via the REO GUI or to edit 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. It contains the software and settings required for configuring the REO Appliance and must be inserted in the REO Appliance whenever you restart it or access the REO GUI. (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.

Backing Up Your REO SoftKey (Pre-Configuration)

Always 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.

Establishing Communication Between the Systems Involved in the Backup Process and the Appliance

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 Adaptec 7211C or Adaptec 7211F.

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.

To establish communication

1 Install the desired software initiator or storage adapter.

Note: For detailed information on various drivers and adapters, see the

manufacturer’s documentation for assistance on assigning targets (REO Devices). You can also check the Overland Web site (www.overlandstorage.com) for the applicable Application Notes.

2 Repeat this step for each system that will access storage on the REO

Appliance.

3 After you complete these configuration steps, choose one of the following:

 If you want to use the default volume configuration of RAID 5 with

logical volumes, proceed to the steps outlined in Creating Logical

Volumes on page 65.

 If you want to use a different configuration, proceed to the steps

outlined in Changing the Volume Configuration on page 59.

CHAPTER

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. If you want to configure and use devices of type Disk, Tape, or Dynamic Tape, you must first create the logical volumes. If you want to create and use a virtual tape-library (VTL), the logical volumes will be created for you based on the information you enter for the VTL. (Even if you create a VTL, you can also create and use separate devices outside the VTL environment.)

X Choose from the following:

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

Creating Logical Volumes on page 65.

 To use the default configuration and create a VTL, proceed to Creating

a Virtual Tape-Library (VTL) on page 85.

Changing the Volume Configuration

You can use the Volume Setup feature in the GUI 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 Wait several minutes, log on to the GUI, and then proceed to the steps

outlined in Configuring REO Devices as Disk or Tape Devices on page 67.

Selecting a RAID Configuration

The REO Appliance supports RAID 0 and 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.)

6 To view the volumes created for the configuration and their status, under

System Menu in the left pane, click Physical Volume Management.

Click Physical Volume Management.

When you first create a new RAID 5 configuration, the Status for each physical unit (PU) is INITIALIZING. After the initial build phase completes (this can take a while, depending on the number of units and the size of each; to display the current percentage complete, click the Physical Volume Management option again), the Status changes to OK. While the volume is in an initializing state, it is not redundant.

Changing the Volume Configuration W 63

Overland Storage REO 1000™ with Protection OS™ Software

Note: Although the volumes are available while they are in an

initializing state, performance is impacted. Overland Storage strongly recommends that you wait until the Status is OK before using a volume.

After the initial build completes, this status changes to OK.

CHAPTER

Disk or Tape Devices

You can configure each REO Device to function either as a disk device (the default) or as a virtual LTO-2 tape device; that is, you can use each device in its native disk format, virtual-tape format, or any combination of the two.

As explained previously, the number of devices that you have depends on the volume configuration that you use. For example, if you use logical volumes with RAID 5, you can create up to 64 disk LUNs, 64 virtual LTO-2 tape devices, or any combination of LUNs and virtual LTO-2 devices up to 64 in total.

Note: If you create devices of type Disk or Tape (or both) and allocate all

available space on the appliances to the devices, the system automatically sends one critical-level alert regarding the storage pool. If you restart the appliance, the system automatically sends the message again.

Using Devices as Disk Devices

X If you want each REO Device to function as a disk device (the default),

proceed to the steps outlined in Associating Targets (Devices) and

Initiators on page 77.

Creating Tape Devices

If you intend to create devices of type Tape or Dynamic Tape, note the following:

 As with standard tape devices, a specific driver (on a Windows system)

or changes to a system configuration (on a UNIX system) might be required to operate with your selected backup software. For more information, check the Overland Web site (www.overlandstorage.com) for Application Notes related to your specific backup software.

 If you are using logical volumes, you can create dynamic tape devices,

which expand and contract to accommodate the size of a specific backup job.

 When you change the configuration of a device, all data currently

residing on the device is deleted. Also, if you change the device type

from Tape to Dynamic Tape, you must restart the appliance.

Configuring REO Devices as Disk or Tape Devices W 67



If you chose to use a RAID configuration with logical volumes (required if you want to create devices of type Dynamic Tape), you must create the volumes before you can change the device settings. For more information, see Creating Logical Volumes on page 65.

 If you choose to enable compression, be aware that various factors

(such as the speed of your backup server, source devices, or network) can significantly affect performance. Additionally, the existing state of the files you are backing up (for example, whether the files are already compressed) can affect the level of compression that might be achieved. Consider these factors when you determine the applicable settings for your backup environment.

Associating Targets (Devices)

CHAPTER

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 appliance, you must provide target and initiator information. Each volume on the appliance is a target (REO Device); the servers are initiators.

An iSCSI name is required both at the targets and at 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).

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 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

Associating Targets (Devices) and Initiators W 77

Overland Storage REO 1000™ with Protection OS™ Software

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 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

78 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 GUI 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 10.20.16.4, 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.

REO SERIES™ 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.

Understanding How Initiators and Targets (Devices) are Connected W 79

(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 1000™ with Protection OS™ 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.name.00e0812dd2e1.00, 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.

80 X Associating Targets (Devices) and Initiators

REO SERIES™ Setup Guide

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.name.00e0812dd2e1.00, 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 device). 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.

Configuring Targets (REO Devices) and Initiators

Each disk or logical volume on the REO Appliance is an iSCSI 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 GUI. You can assign up to eight initiators to each REO disk device (a virtual tapedevice currently supports only one initiator).

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

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

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

To configure the REO Appliance as a backup-and-recovery appliance, you must provide target (REO Device) and initiator (host) information. An iSCSI name is required for both the targets and the initiators. After targets and initiators have been specified, they must be assigned to each other. This must be performed on the server by using the software or hardware initiator, and on the REO Appliance by using the REO GUI, which you completed in the previous section.

Note: For detailed information on various drivers and adapters, see the

manufacturer’s documentation for assistance on assigning targets. You can also check the Overland Web site (www.overlandstorage.com) for the applicable Application Notes.

You can also clear the check box, and type a name (up to 32 alphanumeric characters) in the text box that appears.

4 Select the Emulation Template that you want to use as a guideline for

the setup of the VTL.

The template that you select changes the default number of virtual tapedrives and virtual tape-cartridges that are created. This template is a guideline; you can manually change any of the default settings.

 Selecting the NEO 2000 creates one drive and 30 cartridges.

 Selecting the NEO 4100 creates two drives and 60 cartridges.

 Selecting the NEO 4200 creates four drives and 120 cartridges.

5 In the Bar Code Seed section, if you want the REO GUI to specify the

first bar code label and automatically generate subsequent labels, leave the Automatic check box selected.

If you want to use your own naming convention, you can clear the check box, and type the name (up to six alphanumeric characters) in the text box that appears. The REO GUI automatically includes L2 at the end of each bar code to indicate that the device uses the LTO-2 technology.

The sequencing of the codes begins with the last character listed before the L2. For example, if you manually entered a seed of AAAAAA, the next code is AAAAAB. When the code reaches AAAAAZ, it rolls the second to the last character and starts over (AAAABA, AAAABB, and so on). If you manually entered a seed of 111111, the next number would automatically be 111112.

6 To change the default number of virtual tape-drives that you want to

96 X Working with the REO 1000

Reviewing the Device Summary Page

The Device Summary page provides an immediate view of your REO Appliance and its status. The following shows two examples of what you might see on this page (what you see depends on how you configure your appliance).

This image shows the RAID 5 configuration, with logical volumes. Five logical volumes have been created at this point.

REO SERIES™ Setup Guide

This image shows the JBOD configuration. Two of the REO Devices have been configured to function as virtual LTO-2 tape devices.

The following explains each of the columns:

 REO Device ID. This entry is automatically designated by the REO

Appliance. Depending on the configuration, you might have up to 64 IDs in this list.

 iSCSI Target Name. Displays either the default name assigned by

the REO Appliance or the new name assigned by you.

 Status. Indicates whether the device is Up or Down. In addition to

using an Up or Down label, the color green indicates that the item is okay, orange indicates that the item is in an unprotected state (for example, initializing), and red indicates that the item is unavailable (for example, a disk is missing).

Note: This status is different from that which is shown on the Physical

Volume Management page. For example, if you switch from a JBOD configuration to a RAID 5 configuration, the status of the device ID on the summary page will be Up, while the status for the volume on the Physical Volume Management Page will be INITIALIZING.

 Device Type. Indicates whether the device is exported as a disk drive

or as a virtual LTO-2 tape drive. If you create a Tape Device or Dynamic Tape Device and select the Enable Tape Compression check box, Tape (or Dynamic Tape) appears in italic formatting in this column.

 Size (GB). Indicates the amount of space allocated to the device.

The following image shows the initiators for a RAID configuration using logical volumes.

Tip: To access the Initiator Configuration page for a specific initiator,

click the applicable Initiator Name. To access the Device Configuration page for a specific device, click the applicable REO Device ID.

Understanding the VTL Manager Page

The VTL Manager page displays high-level information about your VTLs and provides access to all pages associated with a VTL. Before you create a VTL, only the upper sections of the page (Capacity Summary and Resources) are displayed. After you create a VTL, the Current VTL Summary section is added.

REO SERIES™ Setup Guide

The following explains each of the items:

 Available Space. Indicates the amount of space that remains on the

appliance.

 Used Capacity. Indicates how much space on the appliance is

currently consumed by the data stored in the VTLs.

 Available VTLs. Indicates the number of VTLs that you can create

(as you create a VTL, this number decreases accordingly).

 Available Virtual Cartridges. Indicates the number of virtual tapes

that are currently allocated for use by a VTL.

 Available Virtual Drives. Indicates the number of virtual tape-

drives that are currently allocated for use by a VTL.

 VTL #. Indicates the number automatically assigned by the REO GUI.

 Name. Indicates the Descriptive Name automatically assigned by the

GUI or manually entered by you.

 Target Configuration. Accesses the Target Configuration page

where you can change settings such as compression, drive counts, and the names of targets.

 Initiator Configuration. Accesses the Initiator Configuration page

where you can add, modify, or remove initiators.

Understanding How Dynamic Tape Devices Work

As explained previously, Dynamic Tape devices contract and expand to accommodate the size of a specific backup job.

When your backup software starts a job, it mounts the Dynamic Tape device as if it were a physical tape, and then begins the backup process by launching a Write operation. During this process, if the tape position in the backup software corresponds to a logical-block address (LBA) that is less than 3, the software treats the device as though it were overwriting a tape, and the REO Appliance reduces the capacity of the device to 1 GB. The appliance then releases the unused storage back into a virtual storage-pool (VSP).

When the backup software reaches an early warning (EW) state (EW is reached when less than 100 MB of space remains on the current device), the REO Appliance reviews the following to determine whether it can expand the size of the device:

Step 1 It determines how much space is already consumed.

 If the current consumption exceeds 70 percent of the VSP, the

appliance sends a “warning” message to the e-mail address you specified for alerts.

 If the current consumption exceeds 90 percent of the VSP, the

appliance sends a “critical” message to the e-mail address you specified for alerts.

Step 2 It determines whether you specified a maximum size for the device.

 If you did not (that is, if you used the default entry of 0 which lets the

appliance use up to 2198 GB of the VSP), the appliance attempts to expand the size of the tape in 1 GB increments until the maximum of 2198 GB is reached.

 If you specified a maximum size, the appliance determines whether

expanding the size of the tape by 1 GB would exceed the specified capacity.

 If the expansion would not exceed the limit, the appliance increases

the size of the tape by 1 GB. If the expansion is successful, an EW is not reported to the backup software. If the expansion is unsuccessful, the EW is relayed to the backup software.

 If the expansion would exceed the limit, an EW is relayed to the

backup software.
