Executive Summary
Becoming Proactive on HA/DR Readiness 3
Availability requirements continue to increase • Business services are complex and multi-layered
• Even small IT changes increase our HA/DR risks
Need to become proactive • Stop fire fighting
• Find and fix the HA/DR risks before they are a problem
Disaster Recovery Advisor • Only solution to cover the entire IT infrastructure
• Proactively reports on the HA/DR risks

Understanding the Real Availability Needs
Availability needs can be higher than expected

What are the Causes of Downtime?
Becoming Proactive on HA/DR Readiness 5
Ever-increasing risk • Each change in the infrastructure introduces risk
Causes of downtime • Most downtime (72%) is caused by configuration management 1
• 80% of mission critical downtime is due to people and process 2

Success Story: Tier 1 Application Disaster Recovery

DRA found: Tier 1 application with no disaster recovery capabilities
• Application owner failed to turn replication on after application maintenance
Situation
• Replication turned back on • Application’s disaster recovery readiness restored • DRA validates the disaster recovery readiness of the application on a weekly basis • Without DRA:
• Would have been identified with a major outage or during annual disaster recovery test

Disaster Recovery Advisor Executive Summary by a Customer
Becoming Proactive on HA/DR Readiness 13
Disaster Recovery Advisory is a polling, analytics, & reporting tool targeted at proactively identifying system configurations of High-Availability & Disaster Recovery.
Put quite simply this is like AntiVirus software that looks for fail-over signatures, instead of virus-signatures.

Success Story: Eliminating a Concentration Risk
17
DRA found: Concentration risk – Clustered VMDKs mounted on the same array
• A single array outage or network outage to Site 1 would bring down multiple sites
Situation
• DRA recommended that VMDK images should be mounted in varied storage locations • Removal of concentration risk • Without DRA:
• Would have been identified with a major host outage • Outage would impact a large number of applications

Success Story: Improving Resiliency and Performance
20
DRA found: Single I/O Path = A single point of failure and performance bottleneck
• SAN I/O was configured with a single path causing performance degradation
Situation
• Configuration changed to meet certified architecture • Application performance and resiliency improved • Without DRA:
• Would have been identified with a major outage • Application would have continued to experience performance degradation

Success Story: Core Web Application High Availability
21
DRA found: Application configuration doubled the risk of downtime
• Downtime in either datacenter would cause an outage in the Core Web Application
Situation
• Core application installed locally • Application will remain online if either site experiences an outage • Without DRA:
• Would have been identified with a major outage • Outage would have impacted customer, Web-facing services
