Executive Summary

VMware virtual infrastructure transforms organizations’ability to protect their datacenterVMware Site Recovery Manager is a new product for disaster recovery that does the following:

Simplifies and automates key disaster recovery workflows: setup, testing, failover, failbackSimplifies and centralizes management of recovery plansMakes it easy for customers to leverage their investment in storage replication technologies with their virtual infrastructure

This combination of disaster recovery automation with the capabilities of VMware Infrastructure reduces time to recovery, risk, complexity and cost


Agenda

Disaster Recovery ChallengesIntroducing VMware Site Recovery ManagerSummary


Requirements for Disaster Recovery

Minimize Downtime

93% of companies that lost their data center for ten days or more due to a disaster filed for bankruptcy within one year of the disaster.

--National Archives and Records Administration

Control Cost

Minimize Risk

73% of executives expressed concern with the costs associated with maintaining a secondary data centre

--Beacon Technology Partners

92% of users surveyed acknowledged that their companies would face serious consequences if they had to implement their disaster recovery plans.

--Dynamic Markets Ltd.

Effective disaster recovery is a business imperative, but is very difficult to achieve


Challenges of Disaster Recovery

Minimize downtime

Reduce risk

Control cost

Many manual processes for recoveryMultiple steps to overcome hardware differencesIncomplete or out-of-date runbooks

Testing requires additional hardware and infrastructureUsually only data is regularly and cleanly updatedFrequent failures during recovery

Simplest recovery requires identical hardwareIdle recovery hardware is impossible to repurposeMultiple third-party products necessary for recovery


Agenda



VMware Vision for Disaster Recovery

Rapid> Automate recovery process> Eliminate failures due to hardware dependencies> Integrate different components of recovery

Reliable> Enable easier, more frequent testing> Turn manual, inconsistent processes into

pre-programmed, repeatable processes

Manageable> Centralize and simplify management of recovery plans> Make disaster recovery protection a property of

virtual infrastructure

Affordable > Eliminate idle recovery hardware> Eliminate dependencies on physical infrastructure

Maps production resources to resources available at recovery site

Resource pools

Network connections

Virtual machine hierarchy

Eliminates complexity of managing recovery site resources

Production Disaster Recovery


Setup: Building Recovery Plans

Turn manual runbook into automated process

Specify steps of recovery process in VirtualCenter

Extensible framework Scripts for specialized tasksCheckpoints for manual stepsEnables integration with physical recovery

Add VMs to DR profileProtect them at another site

Manual failoverShort downtime (minutes)Likely to be individual VMs/applications


Agenda



Site Recovery Manager Core Benefits

Expand disaster recovery protectionNow any workload in a VM can be protected with minimal incremental effort and cost

Reduce time to recoveryAs soon as disaster is declared, a single button kicks off recovery sequence for hundreds of VMs

Increase reliability of recoveryReplication of system state ensures a VM has all it needs to startup

Hardware independence eliminates failures due to different hardware

Easier testing based off of actual failover sequence allows morefrequent and more realistic tests


Summary Site Recovery Manager Leverages VMware Infrastructure to Make Disaster Recovery

RapidAutomate disaster recovery processEliminate complexities of traditional recovery

ReliableEnsure proper execution of recovery planEnable easier, more frequent tests

ManageableCentrally manage recovery plansMake plans dynamic to match environment

AffordableUtilize recovery site infrastructureReduce management costs

Key Concepts in Site Recovery Manager

LUN GroupsThe smallest groups of replicated LUNscontaining complete sets of virtual machines

Protection GroupCollection of virtual machines to protect and the information needed to protect them

Recovery PlanComplete set of steps needed to recover (or test recovery of) virtual machines in one or more protection groups

VMFS VMFS

Recovery Plan A(Array Failure)

Recovery Plan B(Site Failure)


Storage Replication Awareness Link storage replication with virtual infrastructure

Setup: Discover which VMs are replicated

Query array for replicated LUNs

Match replicated LUNs to datastores and VM inventory

Failover: Automate promotion of LUNs at remote site

Test: Automate LUN snapshot creation/deletion for test

Compatibility: Requires FC or iSCSI array integration module – from storage OEM


Specifying the Recovery Process

Pre-program the disaster response

What VMs are shutdown (instant repurposing)

VM startup order

VM-specific recovery steps

Scripts, notifications and prompts

Any action requiring repetition for each VM is automated


Replicating VirtualCenter Management Information

Propagation of VirtualCenter maangement info between sites

Global inventory mappings with per-VM overrides ensure

VMs are organized correctly at the remote site

VMs have the right CPU and memory allocations at the remote site

VMs are plugged into the right port groups at the remote site


Providing Change Control for Recovery Plans

Change control

Role based access control restricts access to setup and execution

Changes to DR plan instantly reflected in the test and failover workflows

Audit trails track who made what changes and when

Recovery and test plans can be exported and printed as needed

Copy Services: Multiple Cluster Mirroring

SVC (B)

What this is► Multiple Cluster Mirroring enables Metro Mirror and

Global Mirror relationships to exist between a maximum of four SVC clusters

► A VDisk can be in only one MM/GM relationship

► One example is shown in the figure (B to A, C to A, D to A) , but other configurations (like triangle-shaped or square-shaped) are also supported

► Both Metro Mirror and Global Mirror are supported within the same overall configuration (for example B to A as Metro Mirror, and D to A as Global Mirror)

► The SVC clusters may take advantage of the maximum number of remote mirror relationships

SAMPLE CONFIGURATIONOTHERS ARE SUPPORTED

Why it matters► Enables customers to copy from several remote sites to a single

SVC cluster at a disaster recovery site

► Supports implementation of consolidated DR strategies

► Helps customers who are moving or consolidating data centers

Copy Services: Increase number of MM/GM relationships

What this is►Creation of up to 8192 Metro Mirror and/or

Global Mirror relationships ►Relationships individually controllable

(create/delete, start/stop)

Why it matters► Improves scalability for increased data protection in

remote copy operations

► Increases the remote copy scope when using Multiple Cluster Mirroring

Copy Services: Multi-Target Reverse FlashCopyWhat this is

► Enables FlashCopy targets to become restore points for the source without breaking the FlashCopy relationship and without having to wait for the original copy operation to complete

► Supports multiple targets and thus multiple rollback points

POINT IN TIME

Why it matters► A key advantage of the SVC Multi-Target

Reverse FlashCopy function is that the reverse does not destroy the original target; thus anything using the target, such as a tape backup process, will not be disrupted; multiple different recovery points can be tested

► SVC is also unique in that an optional copy of the source VDisk can be made before starting the reverse copy operation in order to diagnose problems

What this is► Native attachment to SVC for host

systems using iSCSI HBAs► Not used for storage attachment, which

remains connected through Fibre Channel

► Not used for cluster-to-cluster communication, nor for communication between SVC engines in a cluster

Why it matters► Enables customers to connect host
