ASSESSMENT AND DESIGN

Begin at Home

Disaster Prevention

• How Can we maintain uptime at the core location(s)

• Redundancy

• Diversity

• Power Protection

Focus on Continuity of Operations

• Categorize Applications for Criticality

• Standardize RPO and RTO according to Application Tiers

Audience Discussion

• What Categories have you identified for Applications

• What RPO/RTO have you defined.

Traditional Methodologies

Traditional Approaches to BC and DR solutions have limitations• Tape Backup and Offsite Storage• Data Protection Only

• Very Long recovery time

• Difficult and expensive to test

• High End Storage Replication and Hardware Clustering• Expensive

• Solutions specific to applications

• Bandwidth Intensive

• May not support geographic separation

Traditional Methodologies

Budgetary Constraints and High

Cost of Solutions mean that only a

small percentage of systems are

protected

• 80% of dollars support 20% of applications

• Tier 1 Apps – Over insured

• Tier 2 Apps - Somewhat insured

• Tier 3 Apps - Underinsured

Impact of Virtualization

• Virtualization is an obvious Game Changer

- Removes Hardware from the equation

- No longer necessary to maintain identical storage or hardware

- One-to-one relationship not needed between production and

recovery site

• Hardware independence allows for smaller recovery

site and greater efficiency

• Network Independence – NAT for Legacy Applications

• Testing can be done in a silo environment

• Test Time Objective (TTO)

• Not a Panacea

Impact of Virtualization

• Reduce Total Cost of Ownership/Operations for

Business Continuity- Ease of Administration

- Fewer physical Resources Required for Recovery

- Recovery performed by IT Generalist vs Specialist

- Recovery infrastructure is flexible and scalable for the future

• Workload Protection- Migrate from box protection to application continuity

- A workload encapsulates the data, applications and operating systems

that reside on a physical or virtual host

- Integrated Snapshots provide for shorter Recovery Point Objectives

Impact of Virtualization on Disaster

Recovery

• Eliminate many manual steps

• Standardize key steps in recovery

• Automate recovery process

ManagementSimplify and Automate disaster recovery management

• Implement unified process for protection of all data needed to recover system

• Ensure reliable restore to any hardware

DataSimplify Data Protection

• Consolidate and reuse servers for recovery infrastructure

• Enable productive use of recovery infrastructure during normal operation

Discussion around Solutions

• Solutions in Use today

• How Many Servers and Applications (Workloads)

• Physical or Virtual

• How much Data

• SAN today ?

• RPO/RTO Targets per Workload

• Onsite or Offsite Protection

Automates Failover

Allows automated resource management

Destination Clusters can have non critical workloads spooled down to allow for failover workloads

SRM Storage Connectors

• All SAN Vendors offer replication tools

• SRM requires Site Recovery Adapter at both sides

• Verify SRA compatibility prior to SAN selection/decision
