Page 24 The DXi4500 leverages Quantum’s patented data deduplication technology (U.S. Pat. No. 5,990,810) to dramatically increase the role that disk can play in the protection of critical data. With the DXi4500 solution, users can retain 10 to 50 times more backup data on fast recovery disk than with conventional arrays.

Page 26: Compression
The DXi4500 system can reduce the amount of storage capacity required through a data deduplication process. The term data deduplication refers to the elimination of redundant data. Data deduplication works by recognizing repeated variable-length blocks of data in a stream of data.
Page 27: Remote Replication
Chapter 1: DXi4500 System Description Remote Replication deduplication engine searches for new data entering the DXi and uses a “variable length compression type algorithm” to compare this to existing data in the block pool. Unique blocks are added to the block pool and known blocks are indexed.

Data Replication • Recovering Data • Network Segmentation Data Storage Presentation The DXi4500 can present itself to your host computers in two ways: • Network Attached Storage (NAS) • OpenStorage (OST) Network Attached The DXi4500 can present itself to your host computers as Network Storage (NAS) Attached Storage (NAS).
Page 46: Openstorage (Ost)
Data Storage Presentation OpenStorage (OST) For Symantec NetBackup users, another replication option is available for DXi4500 models through the Symantec Open Storage (OST) API. Specific versions of NetBackup are required. For more details, refer to Quantum DXi4500: Symantec Veritas NetBackup OST Configuration Guide Quantum DXi4500 User’s Guide...

• Data Replication Space Management When data deduplication is enabled on the DXi4500, it is not possible to accurately predict the amount of storage space required because the data deduplication process depends on the type of data being stored. This makes it necessary to define storage space thresholds so the user can be notified when storage space begins to run low.
Page 156: General
Chapter 8: DXi4500 Data Services Space Management Note: When a “low-disk-space” condition occurs on a system, the current system will pause its replication activity and any source systems that are currently replicating to this system are paused. When the “low-disk-space” condition ends, the current system will resume its replication activity and the source systems that were replicating to this system resume.
