Quantum DXi9000User's Guide

TheDXi9000is Quantum’s Enterprise disk backup solution that integrates data deduplication, replication, and direct tape creation technology to connect backup and disaster recovery protection across distributed corporate environments. TheDXi9000disk-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. Scalable to 1020 TB usable capacity, theDXi9000is designed for larger sites and corporate data centers.

TheDXi9000leverages Quantum’s data deduplication technology to dramatically increase the role that disk can play in the protection of critical data. With theDXi9000solution, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays.

With theDXi9000, 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 1020 TB usable capacity, theDXi9000supports large-scale Enterprise environments. Presentations include both VTL (Fibre Channel) and NAS (CIFS/SMB) as well as Veritas OpenStorage (OST) andOracle® 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, NetWorker, Oracle Secure Backup, and ASG-Time Navigator.

DXi Accent distributes deduplication between theDXi9000and the backup server to accelerate backups over bandwidth-constrained networks.

In addition,DXi9000systems optionally support Data-at-Rest Encryption to secure all data stored on theDXi9000. Data-at-Rest Encryption ensures that a hard drive that is physically removed from theDXi9000cannot 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.

  • 有限的元数据操作(包括重命名)。

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