OpenStorage Technology (OST): DR Series System

OpenStorage Technology (OST) is developed by Symantec and provides a logical disk interface for use with network
storage devices. The DR Series system appliance can use OST via plug-in software to integrate its data storage
operations with a number of data management applications (DMAs).
OST allows for better coordination and integration between DR Series system backup, restore, and optimized duplication
operations and the following supported DMA types:
• NetBackup
• Backup Exec
Integration is done via a Dell OST plug-in developed for the DR Series system, through which NetBackup and Backup
Exec can control when the backup images are created, duplicated, and deleted. The major benefit of OST is that it
allows the deduplication operations to happen on the client-side so that network traffic can be reduced.
OST via the Dell OST plug-in allows NetBackup and Backup Exec to take full advantage of such DR Series system
features as data deduplication, replication, and energy efficiency. DR Series systems can access the OpenStorage API
code through the plug-in, which can be installed on the media server platform choice you make (Windows or Linux). The
OST protocol allows the supported backup applications to communicate directly with the DR Series system and
determine whether a specific chunk of data already exists on the system. This process means that if the data already
exists, only the pointers need to be updated on the DR Series system, and the duplicate chunk of data does not need to
be transferred to the system. This process provides two benefits: it improves the overall backup speed, and also reduces
the network load.
When OST is used with the DR Series system, it offers the following benefits:
• OST protocol provides faster and improved data transfers:
– Focused on backups with minimal overhead
– Accommodates larger data transfer sizes
– Provides throughput that is significantly better than CIFS or NFS
• OST and DMA integration:
– OpenStorage API enables the DMA-to-media server software communications
– DR Series system storage capabilities can be used without extensive changes to DMAs
– Backup and replication operations are simplified by using built-in DMA policies
• DR Series System and OST:
– Control channel uses TCP port 10011
– Data channel uses TCP port 11000
– Optimized write operations enable client-side deduplication
