DXi T10 User's Guide

The DXi T10 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 DXi T10 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 15 TB up to 60 TB (DXi T10-60), 30 TB up to 120 TB (DXi T10-120) 60 TB up to 240 TB (DXi T10-240), or 120 TB up to 480 TB (DXi T10-480), the DXi T10 is designed for departmental and medium business customers.

The DXi T10 leverages Quantum’s data deduplication technology to dramatically increase the role that disk can play in the protection of critical data. With the DXi T10 solution, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays.

With the DXi T10, 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.

With up to 60 TB (DXi T10-60), 120 TB (DXi T10-120), 240 TB (DXi T10-240), or 480 TB (DXi T10-480) usable capacity, the DXi T10 supports large-scale Enterprise environments. Presentations include VTL (Fibre Channel), NAS (CIFS/SMB), Veritas OpenStorage (OST) and Oracle® Recovery Manager (RMAN). Integrated tape creation writes physical media directly over dedicated Fibre Channel connections, and supports ISV direct tape creation in NetBackup, Backup Exec, Oracle Secure Backup, and Atempo Time Navigator.

DXi Accent distributes deduplication between the DXi T10 and the backup server to accelerate backups over bandwidth-constrained networks.

In addition, DXi T10 systems optionally support Data-at-Rest Encryption to secure all data stored on the DXi T10. Data-at-Rest Encryption ensures that a hard drive that is physically removed from the DXi T10 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.
