Quantum DXi 7500

Enterprise disk backup with integrated data deduplication

Ideal for distributed corporate environments, the Quantum DXi7500 leverages patented de-duplication technology to increase enterprise disk storage backup capacities by 10-50 times. With de-duplication, inline compression of data, and automated encryption of data-in-transit, WAN replication can be a practical portion of your DR solution.

Designed for large sites and corporate data centers, the Quantum DXi 7500 features up to 240 TB of raw, native data capacity and 8 TB per hour backup performance. Compatible with the DXi3500 & DXi5500 Quantum disk appliances, the DXi7500 features an enterprise-class architecture that eliminates all single-points-of-failure.

Policy-based De-Duplication

The Quantum DXi 7500 enables enterprises to choose how to utilize de-duplication in a manner that meets their needs. De-duplication can be utilized in-line, to minimize disk capacity requirements, or post-processing, to maximize data ingest rates prior to de-duplication. With the DXi7500, each job can be performed to either maximize performance, or minimize capacity allotment, based on the unique requirements of the task.

Integrated Tape Creation

Although disk-based backup is cost-efficient with the DXi disk backup appliances, the DXi7500 supports direct tape creation from the device. This allows data to be archived for long-term retention, without affecting the backup window, application server, or datacenter SAN, and even supports bar-code tracking with the backup application.

Implementation

There are two main methods of implementing deduplication: inline or offline. Inline de-duplication is performed at the host application, or on an appliance sitting on the data path, which minimizes disk capacity requirements, thereby maximizing cost-savings achieved by reduced disk requirements. Inline dedupe has its disadvantages, as performance is negatively impacted by having de-duplication performed on the data path.

Offline de-duplication performs the process at the backup system or appliance, which requires more disk capacity, but maximizes performance by having the process reside outside of the data path, after the backup job is complete. Disk backup solutions such as the Quantum DXi7500 provides for policy-based de-duplication so a each backup job can utilize a de-duplication method appropriate for the workload requirements.
