Accent Path Optimization (APO)

Accent Path Optimization (APO) is a Quantum technology used to route data from a client via the OST Plugin to a single V5000, spreading connections across a number of network interfaces. This technology allows for simplified management of data streams on installations where network bonding is not configured. With APO, there is no longer a need to manually balance backup jobs across network interfaces.

Note: Because the V5000 is a VM and resources are controlled by a hypervisor, not all networking features will work with all installations.

When a client plugin connects to the V5000 on any interface, the V5000 sends the plugin a list of all its interfaces. The plugin will attempt to run the backup job over the fastest interface which contains the least load. For example, consider a V5000 with one 1 Gbps interfaces and 4 x 10 GbE interfaces. The plugin will ignore the 1 Gbps interface and run the backup over the 10 GbE interface with the least amount of load when the backup job is starting.

Automatic handling of downed paths is being considered for a future release.

Note: Running an RMAN and OST Plug-in on the same client is not supported by the DXi system.

OST (OpenStorage) technology allows Veritas NetBackup and Backup Exec to seamlessly integrate with the DXi. Using OST, NetBackup and Backup Exec can manage backups through the DXi and can take advantage of the system's capabilities, such as data deduplication and replication. To use OST, you must first download the OST Plug-in and install it on the NetBackup or Backup Exec media server.

Recovery Manager (RMAN) is an Oracle utility that can back up, restore, and recover database files. Using RMAN, an Oracle database server can manage RMAN share backups through the DXi and can take advantage of the system's capabilities, such as data deduplication and replication. To use RMAN, you must first download the RMAN Plug-in and install it on the Oracle server.

The Accent File System (AccentFS) includes your servers in the deduplication process, to minimize bandwidth and send only unique data over the network. Since the Accent File System appears as a native file system on the client, or backup host, any program that can write to a file system can use AccentFS.

AccentFS enables a hybrid or collaborative approach to deduplication, combining the best features of both target and source-based systems. It moves a portion of the deduplication process to the backup server, so that only unique blocks are transmitted to the target appliance. This system, which leverages many of the underlying functionalities of DXi replication, allows DXi Accent to accelerate backups where network bandwidth is the limiting factor.

The Accent File System uses FUSE (File System in User Space) to export file system requests to a custom daemon. The daemon converts file system requests as appropriate, and transports new user data to the V5000 using the distributed deduplication features of V5000 Accent.

AccentFS is intended to be used by backup applications not supported directly by Quantum application-specific plug-ins.

Download the AccentFS Plug-in for your platform from the Quantum Service and Support Client Plug-ins page.
