Disaster Recovery: Top Virtualization Priority



EMC Advanced Replication Technologies

Storage Replication

Adapter

RecoverPointNetwork-based, Heterogeneous Host and array

• continuous data protection (CDP)

• continuous remote replication (CRR)

• concurrent local and remote (CLR) data protection

VNX Replicator

IP replication with Quality of Service to optimize LAN/WAN bandwidth utilization

VNX MirrorView

Sync/Async replication for flexible recovery-point and recovery-time objective requirements

SRDF Family

The ultimate business continuity and disaster recovery solution for the broadest range of use cases



Clicker Question 1

Most DR solutions today provide peer to peer replication between primary and DR sites. One of the challenges here is that logical corruptions at Primary also get replicated to DR and render the DR copy unusable. Would it be useful if there is a DR solution which works across heterogeneous platforms and provides DVR style roll back.• Yes• No



A Case Study…

CUSTOMER PROFILEBanking and Financial Services



Customer – Challenges in Virtualized Environment

– Multi-vendor environment with growing Virtual infrastructure

– Management pain - Three different disaster recovery

solutions adding to the complexity of management - Lack of single integrated management - Lack of integration with Vmware Infrastructure and

No VM level protection– Increasing client data and aggressive RPO

requirements– No flexibility of different RPO/RTO based

on application SLAs– Unable to meet defined recovery

requirements due to complexity and Low bandwidth between Primary and DR site

Clicker Question 2

How many of you have a single solution which provides Local Recovery as well as Remote Protection capabilities with a single pane of management?

• Yes, I have a single solution• No, I have different solutions for local protection

and remote protection

Synchronous mirroring between local arrays: Recover image, but susceptible to logical

corruption

EMC Approach - Any Point-in-Time Recovery

Traditional recovery methods• Nightly backups, snapshots,

mirrored images plagued by time gaps, corruption

RecoverPoint recovery method• Recovery to any point in time– Mount image to any host in SAN– Full read/write access to image

without protection loss

• Use recovered image for a variety of purposes

– Operational recovery– Backup, testing, or decision support– Reporting

Replicated Data



Overview on Data Consistency

• Applications and data are interrelated (federated)

• All data movement must be stopped/ started at the same point in time

• To restart applications, you must have all the data—not parts of it

• Recovery requires dependent-write consistency across all volumes and systemsSystems share information…

RecoverPoint captures a consistent view

Recoverpoint Consistency Groups (CG)

• Ensures consistency across production and targets

• Application recovery can be independent of SLAs

• Enables independent replication of various applications

• Utilizes consistency groups to organize data
