SAN considerations

The following requirements apply to a SAN environment:

•
In a SAN environment, you must use persistent binding (also known as SCSI mapping, persistent reservation, or persistent naming).
NetVault Backup cannot communicate with a library if its logical address changes as a result of changes in the SAN. Persistent binding assigns a fixed logical address to the device. This address does not change as devices are added or removed in the SAN.
For Fiber Channel Host Bus Adapters (HBAs), you can map the Fiber Channel device address (World Wide Name (WWN) or World Wide Identifier (WWID)) or Loop ID to the logical SCSI address. This configuration ensures that the changes in the SAN have no impact on the NetVault Backup operations.
•
You must also use persistent binding when the server and fiber devices are attached to separate switches or when zoning is implemented.
NetVault Backup does not support multipathing to a tape library or device. To ensure consistent communication path, you must configure only one logical or physical channel for use.
You should not use tape libraries or drives on the same switch or in the same zone that has disk devices attached. Problems might be encountered if packets from both device types co-exist in a SAN environment. Therefore, you should use separate HBAs for these devices.
•
Apple supports multipathing in FC Host Adapter and XserveRAID. Multipathing is often the default setting after installation. However, multipathing is not supported in NetVault Backup. Therefore, the connections should be logically or physically separated to ensure a consistent communication path.

About Quest DR Series systems

The Quest DR Series disk-based data protection appliances optimize utilization with in-line deduplication and compression, and reduce network bandwidth requirements with client-side deduplication processing and deduplicated replication.

These appliances incorporate innovative deduplication and compression technology to help you achieve a data-reduction level up to 15:1. As a result, you can retain more backup data for a longer period in the same footprint.

The Quest DR Series systems use the Plug-in for Rapid Data Access (RDA) to integrate its data storage operations with NetVault Backup. This plug-in is automatically installed on the NetVault Backup machines when you install the NetVault Backup Server or Client software.

For more information about Quest DR Series systems, see the Quest DR Series system Administration Guide.

 
* 
NOTE: The Quest DR Series systems do not support backups over a wide-area network (WAN).

Quest DR Series system prerequisites

Before adding a Quest DR Series system to a NetVault Backup Server, verify that the following requirements are met:

•
DR appliance must be running on DR OS version 4.0 or higher.
•
Configure the required storage options: On the Quest DR Series system, configure the storage options for the container. For more information about the storage options, see the Quest DR Series system Administration Guide.
•
Configure ports for optimized replication: To perform optimized replication operations across a firewall, configure the following fixed TCP ports on the Quest DR Series system to support RDA replication operations:
•
Port 9920
•
Port 11000
•
Port 10011
