Quantum DXi4700 User's Guide

The DXi4700 is Quantum’s entry level and midrange disk backup solution that integrates data deduplication and replication technology to connect backup and DR (disaster recovery) protection across distributed corporate environments. The DXi4700 disk-based backup appliance uses Quantum’s patented data deduplication technology to increase disk capacities by 10 to 50 times, and make WAN replication a practical, cost-effective part of disaster recovery planning. With Capacity-on-Demand scalability from 5 TB up to 135 TB, the DXi4700 is designed for departmental and medium business customers.

Advanced Data Deduplication Increasing Disk Retention for Backup Data

The DXi4700 leverages Quantum’s patented data deduplication technology to dramatically increase the role that disk can play in the protection of critical data. With theDXi4700 solution, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays.

Remote Replication of Backup Data Providing Automated Disaster Recovery Protection

With the DXi4700, 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.

Enterprise Features Provide Secure Repository

The DXi4700 features Capacity-on-Demand scalability from 5 TB up to 135 TB. The DXi4700 offers three options for storage presentation:

• DXi4700 NAS Configuration - Presents storage as NAS shares (CIFS/SMB, NFS, Application Specific) or OST storage servers.
• DXi4700 VTL Configuration - Presents storage as VTL (virtual tape library) partitions.
• DXi4700 Multi-Protocol Configuration - Ability to present storage as NAS shares (CIFS/SMB, NFS, Application Specific), OST storage servers, and VTL (virtual tape library) partitions.

DXi Accent distributes deduplication between the DXi4700 and the backup server to accelerate backups over bandwidth-constrained networks. Compatibility with Quantum's vmPRO software provides consolidated support for backup of physical and virtual servers.

In addition, DXi4700 systems optionally support Data-at-Rest Encryption to secure all data stored on the DXi4700. Data-at-Rest Encryption ensures that a hard drive that is physically removed from the DXi4700 cannot be read using another system or device.

DXi Usage Scenarios

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.
