Business Continuity Considerations• What are your company’s most
critical processes and data needs?
• How much data can you afford to lose?
• How quickly do you need to restore your critical processes?
• How vulnerable are your operations to disasters?Answer these questions with the
right solution to mitigate these risks

Overview and Systems Architecture

Family OverviewReplication independent of host and storage platforms
• Replicate data bi-directionally across different storage arrays from the same vendor—or different vendors
– RecoverPoint/SE supports a single CLARiiON or unified array per-site
– RecoverPoint supports multiple EMC and non-EMC storage arrays
• Creates independent local and/or remote copies of data
• Automates production rebuild/restart for testing, business continuity, and disaster recovery

Family DetailsRecoverPoint—One solution for data protection, replication, and disaster recovery in mixed storage environments• Heterogeneous storage array support
• Integrated with intelligent fabric from Brocade and Cisco
• Supports up to 600 TB of production data
RecoverPoint/SE (for EMC CLARiiON)—One solution for data protection, replication, and disaster recovery for CLARiiON environments• Supports Microsoft Windows host-based
and CLARiiON array-based splitting only
• Single CLARiiON or Celerra Unified per site
• Supports up to 150 TB of production data
Common functionality Continuous data protection (CDP) for one set of
LUNs in one SAN
Continuous remote replication (CRR) between LUNs in two SANs
Continuous local and remote (CLR) data protection that combines CDP and CRR
Heterogeneous operating system support
Flexible point-in-time recovery without production impact
Wizards automate production rebuild/restart from any point in time
Snapshot consolidation enables application-based recovery point objective (RPO)/recovery time objective (RTO); near-instant recovery reduces RTO
Application integration for Microsoft Exchange and SQL, other applications and databases
Integrated consistency groups support federated servers and storage
Synchronous or asynchronous local and/or remote replication with optional dynamic selection policies

Components and Topology• RecoverPoint appliance (RPA)
– Connects to LAN and FC/WAN for replication management and replicating data over FC/IP
– Connects to Layer 2 FC SAN for storage access
– Sold and supported with RecoverPoint– Installed as two to eight appliances per
side
• Application servers– Accesses data that needs to be
replicated
• Heterogeneous storage– Source or Target for replicated data
• RecoverPoint appliance cluster– A group of inter-linked RPAs, working
together closely, to provide replication services
– RPAs in a RecoverPoint cluster are called nodes

Performance and Scalability• Each RecoverPoint cluster
– Supports up to 128 consistency groups– Replicates up to 2,048 LUNs
• Each RecoverPoint appliance (RPA)– Has a steady state rate of 75 MB/s– Eight RPAs with one consistency group
each supports an aggregated write rate of 600 MB/s
– Four RPAs (maximum number for a distributed consistency group) will provide a distributed consistency group with a >240 MB/s steady-state rate for asynchronous replication

Write Splitters• Host-based, fabric-based, and CLARiiON-based write
splitters
• Intercepts writes from the host and splits each write
• Managed through RecoverPoint; installed and upgraded independently of RecoverPoint
Splitter Type How Deployed Overhead
Host-based In I/O stack just above the multi-path software
Adds write traffic at the HBA; no other impact
Fabric-basedIn intelligent storage services hardware on a Brocade- or Cisco-based switch
Operates at wire speeds; no impact
CLARiiON-based
In FLARE operating system; active in both storage processors No impact
RecoverPoint/SE only supports a Windows host-based write splitter and the CLARiiON-based write splitter.
14© Copyright 2010 EMC Corporation. All rights reserved.
Host-Based Write Splitters• Supported on AIX*,
Solaris*, and Windows
• Lightweight code that installs on each server that accesses a replicated LUN
• Splits or ‘Duplicates’ writes to production LUNs and sends a copy to the RPA

Cascaded Replication• CLR replication for a three-site disaster restart solution
– Replicates data from a primary site to a secondary site – Also replicates data from a primary site to a tertiary site– Improves RPO and RTO at tertiary site over standard CRR– Provides disaster restart by converting secondary site into
production– Provides disaster recovery from the tertiary site
• Requires stretched fabric between primary and secondary
• Uses secondary site as bunker for replication data
• Retains recoverability at the tertiary site – Survive a regional disaster that incapacitates both the primary
and bunker site– Protects latest and all earlier consistent point-in-time images

VMware AffinityvCenter Site Recovery Manager (SRM)
• VMware SRM consistency groups – Can only be monitored– Require maintenance mode for
snapshot access, but failover cannot occur in this mode
• SRM uses latest image during its test or disaster failover
– A restriction on vCenter Site Recovery Manager not RecoverPoint
– CDP replica and journal not available during a real failover (only vCenter Site Recovery Manager test mode)
• EMC developed adapter integrates with VMware SRM and supports VMware vCenter Server
– Supports ESX 3.5 and ESX 4.x

Automated Failback After SRM Failover
• Integrates into vCenter Server
• Automates failback by:– Powering down VMs at
recovery site– Replicating LUNs from
recovery to protected site – Reestablishing replication
between protection and recovery sites
– Registering VMs – Powering on VMs at protected
site
• Provides real-time status
• Controlled in vCenter Server
• Available in the “Recent Tasks” area of the vCenter Server
34© Copyright 2010 EMC Corporation. All rights reserved.
VMware Integration with vCenter Server• RecoverPoint queries vCenter Servers for list
of VMs
• Protection status is shown on RecoverPoint GUI
• Protection status is available from RecoverPoint CLI
• RecoverPoint issues an alert for unprotected VMs
– Existing VM not protected by RecoverPoint– Existing VMs storage moved (e.g., Storage
vMotion)– New VM created that is not protected by
RecoverPoint
• Optional filtering (e.g., ignore checking protection status) by ESX server, VM or LUN

development – Surgically repairing data – Fast production resynchronization– Source for backup, data analysis,
disaster recovery, and development/test
• Request recovery via GUI, CLI, or through integrations with NetWorker, Replication Manager, SRM, or Cluster Enabler 4.0
• Image recovered as read/write
• Any change to image saved in journal

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 systems
Systems share information…RecoverPoint captures a consistent view

Consistency Groups (CG)• RecoverPoint ensures
consistency across production and targets
• Application recovery can be independent of SLAs
• RecoverPoint enables independent replication of various applications
• RecoverPoint utilizes consistency groups to organize data
