3	The Globalization of Business “It is estimated that more than one third of all worldwide businesses are run on a seven-day- a- week and 24- hour- a- day basis, and that number is expected to grow to over 60 percent in the near future Source: Dataquest / Contingency Planning Research
4	The Cost Of Business Downtime
5	The Business Requirement The design goal of High Availability Software is to minimize costly system downtime and to “reduce the time to recovery” in order to keep customers and business working together.

9	What RemoteSHADOW helps our customers accomplish “uniquely well” Protect data Local and Remote data replication Continue business Data is immediately available at the remote site Save on Unnecessary Operational Expenses Bandwidth can be sized to average not peak No artificial bandwidth purchases paid monthly No Surprises Avoid “Application Slowdown” during unexpected peak periods
10	How does RemoteSHADOW work? Replicates Data from one system to another Local Remote Modes of Operation -- balancing costs and efficiency Synchronous all I/O’s must complete before continuing Asynchronous Local I/O’s complete at production speed Remote I/O’s controlled
11	RemoteSHADOW Features Unique RemoteSHADOW features Synchronous and Asynchronous Communication Out of Sync Tolerance Save dollars on Operational Bandwidth Expense RemoteSHADOW always works to stay synchronous Production Systems continue Network Restart – Automatic Reconnect No Data Loss Remote “local” SHADOW (2+2 Shadowing) Remove SHADOW Set Members for off line processing Data Collection Reporting Defines actual Bandwidth need Avoid overspending on bandwidth
12	RemoteSHADOW Features Unique RemoteSHADOW features… Ten (10) Member Shadow Sets Supported for high levels of redundancy Logical Volume Copy Operation OpenVMS Clusters Fully Supported OpenVMS Volume Shadowing Supported Tru64 TruClusters Supported
13	Synchronization Tolerance -- Dynamic Bandwidth Balance Bandwidth Expense and Performance
14	RemoteSHADOW’s Dynamic Bandwidth reduces Operational Costs
15	Network Restart Tolerance Isolates Production Systems from Network Outages Recovery is automatic and transparent
16	Network Restart Tolerance RemoteSHADOW reconnect: Specifiable in seconds or minutes Dynamic can be reset even during a failure Automatic Reconnection I/O’s continue upon a successful restart, Remote member is removed if time out occurs Size of the “funnel” or tolerance can be updated dynamically Synchronization Tolerance may be updated dynamically
17	Remote Site Shadowing... 2 + 2 Remote Shadowing Double Failure No Additional Impact on Network Performance
18	Why RemoteSHADOW? RemoteSHADOW Experienced and Proven SHADOW introduced in 1983 RemoteSHADOW introduced in 1990 RemoteSHADOW defined the concepts Tested under “fire” at hundreds of sites Our customers back us up! Worldwide Customer Base Large Financial Industry presence
19	RemoteSHADOW^® meeting Customer Expectations with... RemoteSHADOW low “Cost of Operations reduces the time to recovery” Supports installed hardware and storage Reduces network traffic by mirroring only critical data Flexible Mode of Operation Synchronous Asynchronous Business Recovery within minutes upon application switchover Data Integrity/Data Security Minimal Impact on Production Systems Performance 100% Application Transparent General Purpose (file systems/databases) Isolates Production Site from Network Outages Multi Platform Support
