Symantec OpenStorage (OST) API Support

Support for OST is a standard feature for all DXi6900 Series units, allowing users to write data to OST logical storage units (LSUs) and enabling application-aware replication in NetBackup and Backup Exec environments. Support includes Optimized Duplication, Auto Image Replication (AIR), Granular Restore Technology (GRT), and OST path-to-tape introduced in NetBackup 6.5.4. OST Optimized Synthetic Full Backups is supported to reduce network I/O and shorten time to perform full restore from incremental backups.

DXi Accent

DXi Accent software, a standard feature on all DXi6900 Series models, allows the backup server to collaborate in the deduplication process, off-loading part of the data reduction activity so that only unique blocks are sent over the network to the DXi appliance. This distributed approach provides faster backups over bandwidth-constrained LANs or WANs. DXi Accent can be enabled or disabled on a per-media server basis. Initial support for DXi Accent is provided through the NetBackup OpenStorage (OST) API and Oracle RMAN (DXi6900-S only).

Data-At-Rest Encryption

Data-at-Rest Encryption uses Self-Encrypting Drive (SED) technology to secure all data stored on the DXi6900. This includes file data and metadata, configuration files, and the DXi software and operating system. When Data-at-Rest Encryption is enabled, all hard drives in the DXi are paired with the disk controllers using encryption keys. After this, accessing data on the drives requires the same encryption keys and controllers that were used to write the data. This ensures that a drive that is physically removed from the DXi cannot be read using another system or device.

DXi Advanced Reporting

DXi Advanced Reporting, which is included on all DXi appliances, sets new standards for onboard intelligence by giving users a detailed view of internal appliance operations and provides them with years of backup and replication data for extended trend analysis. DXi Advanced Reporting reduces administration time, improves operations, streamlines performance tuning, and helps users maximize the value of their DXi appliances.

Quantum Vision

Quantum Vision® provides powerful monitoring, reporting, and analysis tools for all of the Quantum storage devices in your backup environment. You can view the status and track the performance of multiple DXi disk backup systems, vmPRO software, DXi V-Series virtual devices, Scalar LTFS devices, and Scalar libraries using a single flexible interface.

Q-Cloud Ready

Quantum Q-Cloud provides a new, innovative Cloud backup and DR strategy designed specifically for virtual and physical environments. Q-Cloud is a subscription-based solution that allows customers of all sizes to keep more data offsite for a longer period of time by efficiently replicating data to the Cloud with a simple, cost-effective approach. Q-Cloud is a secure cloud data protection solution that integrates with your existing backup software and reduces risk for IT Departments with a convenient option to efficiently replicate your data to the cloud.


Replication compatible with all DXi-Series products, schedules and bandwidth use set in DXi6900 scheduler. Replication is asynchronous, one-to-one, one-to-two, or multiple-to-one configurations; partitions in same unit act as replication source or target; units with partitions acting as replication targets can also support local backup; data is deduplicated and encrypted (AES 256-bit) prior to transmission; cartridge-by-cartridge and file-by-file replication provides automated access to data at the target; CLI support scripting/scheduling. Provides application-aware replication with NetBackup and Backup Exec OST interface.

DXi Software

Combined with StorNext 5 high-performance file system, variable-length deduplication, built-in intelligence with iLayer Management for DXi, and efficient replication, customers can realize their data protection goals. Quantum DXi's Software delivers the most efficient deduplication algorithm, high-performance file system with tuned optimized storage, and the most comprehensive management suite available. Combined, the Quantum DXi Software stack provides customers with the greatest reduction in disk resources, highest performance and broadest scale in a single system, and management capabilities designed to reduce overall management time and expenses.
