Disasters Happen. Do You Need Protection?

43% of companies experiencing disasters never re-open, and 29% close within two years (McGladrey and Pullen)

93% of business that lost their data center for 10 days went bankrupt within one year (National Archives & Records Administration)

40% of all companies that experience a major disaster will go out of business if they cannot gain access to their data within 24 hours (Gartner)

Top executives say 10 hours to recovery; IT managers say up to 30 hours (Harris Interactive)

Business-Critical Applications Require Business Continuity

Availability Expectations on vSphere Continue to Increase RTO’s decreasing from >24 hours to <12 hours

So How To Overcome This?

vSphere Provides The Best Foundation For Disaster Recovery

Flexible Infrastructure •  Eliminate need for identical hardware across

sites •  Enable waterfalling of equipment to recovery site

Simple Application Protection •  Entire system – including application, OS,

and data – is stored as virtual machine files •  Entire system can be protected with data

protection tools

Cost-Efficient Infrastructure •  Reduced hardware requirements at recovery site •  Use recovery hardware to run low-priority apps

Encapsulation

Consolidation

Hardware Independence

§  Error-prone

§ Quickly falls out of sync with apps and infrastructure changes

§  Simple recovery plan set up in minutes

§  Fewer steps means far less room for errors

vSphere Replication For Cost-Efficient, Simple Replication

Reduce storage costs by 2X

• Support for heterogeneous storage across sites, including non-replicating storage

• Use lower-end or older storage at failover site

Eliminate replication software costs

• vSphere Replication included with Site Recovery Manager at no additional cost

Manage replication directly from vCenter

• Eliminate complex interactions with storage teams

Manage replication at the individual VM level

• Eliminate need for complicated VM-to-LUN mapping

15 minute RPOs

• Set RPOs between 15 minutes and 24 hours

Efficient network utilization • Replicate only changed disk

areas

Highly scalable • 500 virtual machines

Limitations • No automated failback • File-level consistency only

(except planned migration) • No FT, templates, linked

clones, physical RDMs

Automate DR Failover Processes

Overview

Benefits

Automatically detect site failures §  Require user to manually initiate failover

Automate recovery process §  Stop replication and present replicated LUNs to

vSphere §  Execute user-defined recovery plan

Ensure fast and predictable failovers and migrations §  Consistently meet business requirements

Minimize risk of user errors

Planned Migrations For App Consistency & No Data Loss

Overview

Benefits

Two workflows can be applied to recovery plans: §  DR failover §  Planned migration

Planned migration ensures application consistency and no data-loss during migration §  Graceful shutdown of production VMs in

application consistent state §  Data sync to complete replication of VMs §  Recover fully replicated VMs

Better support for planned migrations §  No loss of data during migration process §  Recover ‘application-consistent’ VMs at

recovery site

Planned Migration

Site B Site A

1 Shut down production VMs

2 Sync data, stop replication and present LUNs to vSphere

Simplify failback process §  Automate replication management §  Eliminate need to set up new recovery plan

Streamline frequent bi-directional migarations

Automated Failback To Streamline Bi-Directional Migrations

Re-protect VMs from Site B to Site A §  Reverse replication §  Apply reverse resource mapping

Automate failover from Site B to Site A §  Reverse original recovery plan

Beyond DR: Disaster Avoidance And Planned Migrations

Recover from unexpected site failure

• Full or partial site failure

The most critical but least frequent use-case

• Unexpected site failures do not happen often

• When they do, fast recovery is critical to the business

Anticipate potential datacenter outages

• For example: in case of planned hurricane, floods, forced evacuation, etc.

Initiate preventive failover for smooth migration

• Leverage SRM ‘planned migration’ to ensure no data-loss

•  ‘Automated failback’ enables easy return to original site

Most frequent SRM use case

• Planned datacenter maintenance

• Global load balancing

Streamline routine migrations across sites

• Test to minimize risk • Execute partial failovers • Leverage SRM ‘planned

migration’ to ensure no data-loss

•  ‘Automated failback’ enables bi-directional migrations

Points to consider first

§  Distinguish between Service Disruption and Disaster – What is and What’s Not

§  Availability <not equal> to Disaster Recovery

§  Disaster Recovery Procedures (DRP) and Business Continuity Procedures – Understand the Differences

§  Important point to note about DRP and BCP solution.

25

Important point to note about DRP and BCP solution

§  No single product provides disaster recovery or business continuity

§  Companies are dynamic §  New systems and applications are brought on-line §  Old systems and applications are retired

§  DRPs and BCPs must be constantly updated to match the current operations reality.

§  Disaster recovery and business continuity are not products §  No one product can give a company “instant disaster recovery protection” or

“instant business continuity planning”. §  VMware Site Recovery Manager (SRM) is a product that helps companies

quickly restores an organization’s IT infrastructure with automation. §  SRM must be combined with other products and technologies and with a

effective disaster recovery planning and effective business continuity planning.
