Advanced Load Balancing and Link Failover
vRanger supports a single host name and IP address per repository. For EMC® Data Domain® systems that require multiple 1 GbE links to obtain full system performance, you must set up multiple storage servers on the Data Domain systems — one per interface — and target the backup policies to different storage servers to spread the load on the interfaces.
The Advanced Load Balancing and Link Failover feature allows for combining multiple Ethernet links into a group. Only one of the interfaces on the Data Domain system is registered with vRanger. The EMC® Data Domain® Boost (DD Boost™) Library negotiates with the Data Domain system on the interface registered with vRanger to obtain an interface to send the data. The load balancing provides higher physical throughput to the Data Domain system compared to configuring the interfaces into a virtual interface using Ethernet level aggregation.
The benefits of Advanced Load Balancing and Link Failover are as follows:
Configuration restrictions
• Since only one interface group is supported on the EMC® Data Domain® system, for connecting more than one backup server, a switch is needed in the middle.
Managed file replication
File replication replicates a single file. The replication request is initiated by the application. By default, the backup servers set up replication jobs between two EMC® Data Domain® systems after authenticating them using the pre-configured EMC® Data Domain® Boost (DD Boost™) user name and password. If the replication feature is enabled, when an optimized job is set up by backup servers, the session between the source and destination Data Domain systems is encrypted using Secure Sockets Layer (SSL), ensuring all image data and metadata is sent encrypted over the WAN.
Replication notes
• Both the source and the destination EMC® Data Domain® systems must be running Data Domain OS 5.2 or later to use this feature.
Low-bandwidth optimization
The low-bandwidth optimization option is available to EMC® Data Domain®s systems with an installed Replicator license. The option is enabled on a Data Domain system and applies to all replication jobs on that system.
