Configuring InfiniGuard with OpenStorage Technology (OST)

The OST presentation requires the Veritas NetBackup host application and the OST Plug-in client installation on the media server.  Plug-in clients are host operating system dependent and are supplied by Infinidat. To use the InfiniGuard DDE in OST mode, you must configure an OST storage server and LSUs on the DDE. You must also map the LSUs on the NetBackup Media Server so that NetBackup can perform backups and restore from them. Additionally, policies for optimized duplication (OST replication) need to be set on the NetBackup server.

This section details InfiniGuard configuration with OST and is a supplement to InfiniGuard 3.0 Configuration and Best Practice Guide for Veritas NetBackup; which details OST Plug-in Installation, Veritas NetBackup Configuration and Operations.

Configuring InfiniGuard DDEs for OST


To use the InfiniGuard DDE in OST mode, you must configure an OST storage server and LSUs on the DDE. You must also map the LSUs on the NetBackup Media Server so that NetBackup can perform backups and restore from them. Additionally, policies for optimized duplication (OST replication) need to be set on the NetBackup server.

Configuring the OST Authentication

To authenticate the OST storage servers on a media server, you must create local OST user credentials. After you create the OST user credentials, enter them in the backup application to authenticate OST devices on the media server.

Note

Authentication between the OST Plug-in and InfiniGuard DOES NOT USE Active Directory. Instead, you must add new OST user credentials on the InfiniGuard and the media server

To create OST user credentials:

  1. Log in to the InfiniGuard management console.
  2. Navigate to the Configuration > System > Manage Users page.
  3. Click Add.
  4. Specify the Username and New Password that will be used to authenticate the storage servers on the media server.
    Note: For username, alphanumeric characters are allowed, as well as underscores ( _ ) and hyphens ( - ). For password, alphanumeric characters are allowed, as well as the following special characters: ` ~ ! @ # $ % ^ & * ( ) - _ = + [ { ] } \ | ; : ' “ , < . > / ? 
    Provide the same credentials on the media server. Do not include the domain name in the username.
  5. Click Apply.
  6. On the NetBackup management console, add credentials for the Storage Server, making sure to use the same OST username and password you entered on the InfiniGuard.

Configuring OST Backup and Replication Environment

The OST page allows you to configure the InfiniGuard to present its storage capacity as storage servers using OpenStorage (OST) technology. You can add one or more Logical Storage Units (LSUs) to a storage server. Storage servers and LSUs are compatible with backup applications that support OST, such as Veritas NetBackup. In addition, OST data can be duplicated (replicated) between InfiniGuard systems using NetBackup (see OST Data Replication).

To access the OST page, click the Configuration menu, and then click the OST tab.

The OST page contains the following tabs

Configuring Storage Servers

The Storage Servers page allows you to manage OST storage servers on the InfiniGuard DDE. You can view information about existing storage servers, add or edit storage servers, and delete storage servers.

To access the Storage Servers page, on the OST page, click the Storage Servers tab.

The number of backup images on the storage server.

Concurrent Optimized Duplication

The status of Concurrent Optimized Duplication for the storage server (Enabled or Disabled), as well as the configured targets (if any).

Description

A brief description of the storage server (if available).

Additional Information

  • Click a column heading to sort the rows in the table by that column. Click the column heading again to reverse the sort order.
  • The connections of a storage server that are used equals the data streams plus one for each LSU polling. A backup job may generate more than one data stream if the data can be read in parallel. For example, a policy that is backing up A, B, C, and D drives of a Windows system can generate four data streams in parallel.

Adding a Storage Server

Add a storage server to present the storage capacity of the InfiniGuard as LSUs that are compatible with backup applications that support OST. You can add up to 100 storage servers. When adding a storage server, you must also add an LSU to the storage server. (For more information about LSUs, see LSU)

Note

Data on storage servers is always deduplicated.

To add a storage server:

  1. Click Add.

The Add Storage Server page displays.

Add Storage Server Page

2. Under Add Storage Server, enter information about the storage server:

Name

Enter the name of the storage server.

Caution: Do not use an underscore ( _ ) in the name of the storage server.

Note: OST storage server names are not case-sensitive. For example, if you create a storage server named ost1, you cannot create another storage server named OST1 because the system considers the names to be the same.

Description

(Optional) Enter a brief description of the storage server.

Max Connections

Enter the maximum number of connections allowed to the storage server. To disable OST, enter 0 connections. To enable OST, enter 3 to 65536 connections.

Note: Infinidat recommends setting Max Connections to 300.

Enable Concurrent
Optimized Duplication

Select the check box to enable optimized duplication during OST ingest.

Concurrent Optimized Duplication is disabled by default. If enabled, as data is written to the storage server, it is simultaneously replicated to the target InfiniGuard DDE. When optimized duplication or Automatic Image Replication subsequently occurs, the operation is more efficient because a portion of the required data has already been replicated to the target storage server.


Note: To configure the target DDE, (see Adding a Replication Target).

Note: When Concurrent Optimized Duplication is enabled, all data on the storage server is duplicated, not just the specified images.

3. Select the check box for each optimized duplication target you want to duplicate the storage server to. When the storage server is duplicated, its data will be sent to all selected targets.

4. Under Logical Storage Unit, select the type of LSU to add to the new storage server:

Available Capacity

 (Recommended for best performance) Select this option to add an LSU that uses the available capacity on the system.
You cannot add an available capacity LSU to a storage server that already contains an LSU. Also, if you add an available capacity LSU to a storage server, you cannot add additional LSUs to that same storage server.

Note: After you add an LSU that uses the Available Capacity option, you cannot change the LSU to use the Specific Capacity option. Instead, you must delete the LSU, then add a new LSU and choose the Specific Capacity option (see Deleting an LSU).

Specific Capacity

Select this option to specify the physical capacity of the LSU, and then enter the following information.

  • LSU Name - Enter the name of the LSU.
  • Physical Capacity - Enter the physical capacity of the LSU (1 to 1048576 GB).

Note: Infinidat recommends setting LSUs to maximum size (1048576 GB) because spanning them on a backup is not possible.

5. (Optional) In the Description box, enter a brief description of the LSU.

6. (Optional) Select the Enable Automatic Image Replication check box to automatically replicate (duplicate) data on the LSU to a remote LSU on another InfiniGuard DDE.

Automatic Image Replication (AIR) is disabled by default. If enabled, data on an LSU is automatically replicated to a remote LSU that resides on a DDE in a different NetBackup domain. The timing of the duplication, as well as the backup images that are duplicated, are determined by the storage lifecycle policies (SLPs) configured in NetBackup.
OST AIR requires NetBackup 7.6 or higher.

Note

You must configure at least one remote user before you can enable Automatic Image Replication (see Manage Remote Users).

7. If Automatic Image Replication is enabled, select the replication target you want to replicate images to. (You can select only a single target.) When images are replicated, data will be sent to the selected target.

8. If Automatic Image Replication is enabled, specify the following information:

Target IP Mapping

The Target IP Mapping page allows you to map a target data IP address to route all network traffic sent to the data IP address to the specified replication IP address instead. This can be necessary if the target InfiniGuard is configured with different network interfaces (and therefore different IP addresses) for data and replication traffic (see Network).

Generally, OST traffic is routed to the data network segment. However, the OST Automatic Image Replication (AIR) and Concurrent Optimized Duplication features use the replication network segment to transmit data to the target system. (Optimized duplication can optionally use the replication channel.) When a data IP address is mapped to a replication IP address, OST traffic that is sent to one of the IP addresses is routed to the other IP address as necessary.

Additional Information

  • You must add target IP mapping information if you are performing optimized duplication on a segmented network and replication is not configured between the source InfiniGuard and target InfiniGuard.
  • Infinidat does not recommend mapping multiple data IP addresses to a single replication IP address. If you have mapped multiple data IP addresses and the routing is not working, try removing the additional data IP addresses, and map only a single data IP address.
  • To switch from using the replication channel to the OST channel for optimized duplication, replication must be unconfigured.

To access the Target IP Mapping page, on the OST page, click the Target IP Mapping tab.

Target IP Mapping page

Tasks

Use the Target IP Mapping page to perform the following tasks:

Target IP Mapping List

The Target IP Mapping list displays the following information for all mapped IP addresses:

  • The OST Plug-in is installed on the media server.
  • NetBoost is enabled on the InfiniGuard. (By default, NetBoost is disabled on the InfiniGuard.)
  • NetBoost is enabled on the media server. By default, NetBoost is enabled on the media server when you install the OST Plug-in.

When all these requirements are met, NetBoost will be used for all OST transport between the media server and the InfiniGuard. Otherwise, normal OST transport will be used. for information about the maximum number of connections when NetBoost is enabled see, Maximum Number of InfiniGuard NetBoost Jobs .

Note

When InfiniGuard NetBoost is in use, you can monitor NetBoost performance information in the InfiniGuard remote management console, on the Status > NetBoost page. 

Enabling or Disabling NetBoost on the InfiniGuard

By default, InfiniGuard NetBoost is disabled on the InfiniGuard. To use NetBoost, you must enable it on the InfiniGuard.

Note

If NetBoost is enabled, all media servers that are using the same InfiniGuard DDE must have the latest OST plug-in installed.

To enable or disable NetBoost on the InfiniGuard:

1. Access the InfiniGuard DDE remote management console.

2. Navigate to the Configuration > OST > NetBoost page.


3. To enable InfiniGuard NetBoost, click the Enable Deduplication with NetBoost check box.
Or, to disable InfiniGuard NetBoost, clear the Enable Deduplication with NetBoost check box.

4. Click Apply.

5. To enable or disable encryption when sending OST data from the media server to the InfiniGuard, select the Change Encryption Type link or go to the Configuration > System > Security > Data Encryption page.
6. Select an option in the Encryption drop-down box. Encryption applies to all OST data traffic.

None

OST data is not encrypted.

Default AES 128

OST data is encrypted using AES 128-bit encryption.

Default AES 256

OST data is encrypted using AES 256-bit encryption.

TLS with AES 256

OST data is encrypted using AES 256-bit encryption with Transport Layer Security (TLS)


Additional Information

  • Using 256-bit encryption provides a stronger level of security but may have an impact on system performance in some situations.
  • If encryption is enabled, all other OST data will use TLS with AES 256 encryption.

7. If you selected any encryption option, you must install the required certificate and key files on the InfiniGuard:

    • Certificate File
    • Private Key File
    • Certificate Authority File
    • Rejection List File

To install a file, click the Browse button to browse the system and locate the file, and then click Open. Click Install to install the selected file on the InfiniGuard.

Caution

Installing certificate files requires a system reboot immediately after the changes are applied. Wait for at least 15 minutes before logging back in.

Additional Information

  • You can install new certificate and key files at any time, as long as there are no active network connections between the OST media server and the InfiniGuard.
  • To remove all certificate and key files, click Restore Factory Defaults.

8. Click Apply.

Enabling or Disabling InfiniGuard NetBoost on the Media Server

By default, InfiniGuard NetBoost is enabled on the media server when you install the Infinidat OST Plug-in. Because use of InfiniGuard NetBoost can be enabled individually on each InfiniGuard, there is typically no need to disable NetBoost on the media server. However, you might want to disable NetBoost on an individual media server if that media server is equipped with a slow CPU or if the type of data being backed up is not easily deduplicated. Note that you may mix NetBoost-enabled and NetBoost-disabled media servers with a single InfiniGuard.

To enable or disable NetBoost on the media server:

1. Open the configuration file for editing:

Linux/Unix

/usr/INFINIDAT/INFINIDATPlugin.conf

Windows

C:\libstspiINFINIDAT.ini

2.In the configuration file, locate the IO_PATH variable.

To enable NetBoost

Set the value of the IO_PATH variable to 4. For example: IO_PATH=4

To disable NetBoost and revert to using traditional OST transport

Set the value of the IO_PATH variable to 1. For example: IO_PATH=1

3. Save and close the configuration file.

Maximum Number of InfiniGuard NetBoost Jobs

When InfiniGuard NetBoost is enabled, a maximum of 768 concurrent NetBoost jobs can be run against each DDE in the InfiniGuard.

If the connection limit is reached, one or more of the following messages (or similar) is logged in the InfiniGuard log in the /var/log/messages directory:

  • VServer "hybrid-dedupe-no-encrypt" limit reached (limit 768).
  • VServer "hybrid-dedupe-no-encrypt" connection limit failed due to VServer "hybrid-group".
  • VServer "hybrid-group" connection limit failed due to VServer "hybrid-remote- group".
  • VServer "hybrid-remote-group" limit reached (limit 768).
  • VServer "hybrid-dedupe-no-encrypt" connection limit failed due to VServer "hybrid-group".
  • VServer "hybrid-group" limit reached (limit 768).

In addition, NetBackup displays a message:

NetBackup - The following progress message displays:

Critical bpdm (pid=12515) image open failed: error 2060020: storage server connection limit exceeded

When the connection limit is reached on the InfiniGuard, The OST plug-in retries the connection for 300 seconds by default. If the connection cannot be established after 300 seconds, the connection times out and an error is returned.

The default connection timeout is 300 seconds.

To change the timeout value, edit the following setting:

DATA_CONNECTION_BUSY_TIMEOUT

Linux  /usr/INFINIDAT/INFINIDATplugin.conf  file

Windows C:\libstspiINFINIDAT.ini file
