DXi9200 User's Guide

The DXi9200 leverages Quantum’s data deduplication technology to dramatically increase the role that disk can play in the protection of critical data. With the DXi9200 solution, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays.

With the DXi9200, users can transmit backup data from a remote site to a central, secure location to reduce or eliminate media handling. DXi™‑Series replication is asynchronous, automated, and operates as a background process.

DXi Accent distributes deduplication between the DXi9200 and the backup server to accelerate backups over bandwidth-constrained networks.

In addition, DXi9200 systems optionally support Data-at-Rest Encryption to secure all data stored on the DXi9200. Data-at-Rest Encryption ensures that a hard drive that is physically removed from the DXi9200 cannot be read using another system or device.

DXi storage presentations are optimized for backup usage rather than file sharing. Backup application usage is typically characterized by:

• Aggregated name spaces and file contents.

• Limited direct, active file access.

• Limited browsing, scanning, or stating.

• Limited metadata manipulation (including rename).

Note: Usage diverging from these characteristics must be qualified to ensure acceptable behavior with respect to functionality, performance, replication, and recovery.
