DRMS Replicates All file types:

– fixed– sequential– relative– stream– 1-way server queue– message queue

VOS internal commands – Batch– Command-line– Macros

Supports dynamic file wild-cards



- 5 -

DRMS is scalable Replicate data in any direction Many-to-one operation (A-to-C, B-to-C) Dual-mode operation (A-to-B, B-to-A) Supports all VOS platform (PA7100, PA8000,V-Series) Supports all VOS release The result: a “Load-Balancing” solution



- 6 -

DRMS is simple No additional hardware or software No application changes (not even bind files !) Use existing communications One table (standard TIN) to configure Practically no learning curve



- 7 -

Hands-off operations Designed for 24x7 hands-off operation from boot to

shutdown No ongoing maintenance required Line failure & recovery Line switching - alternate routing Allows configuration changes without interruption

(bouncing the software)



- 8 -

Performance Designed to preserve Primary application performance and

integrity Operation is “pushed” to remote system immediately Execution occurs on target system Reported 5% overhead at full Continuum capacity (@25 TPS)

Online Monitors & Reports Online monitor:

– Total transactions– Transaction processing rate– Queuing activities and statistics

Reports– Daily statistics– By-file/by-I/O type statistics– Error reporting and handling– Debugging traces

Software Vs. Hardware Solutions No downtime – the data on the backup module is immediately

available. Software solutions are very flexible - you can pick and choose

individual files and directories. (A hardware solution is an all-or-nothing)”

It is easier to incorporate a software solution into DR operations procedures, management of the applications and rapid recovery.

No hardware changes whatsoever; disks continue to be duplexed (hardware solutions require simplexing your disks)

Software solutions are scalable – you can easily mirror from multiple systems into one; A-to-B, B-to-A; all at the same time.

GUI HTML-based monitoring facilities. No performance impact on Production. Price / Performance
