2 Real Time Recovery Points & Recovery from Disaster Historical Backup: Recovery Point Every 24 Hrs Snapshot / Clone Technology: Recovery Point Every 4-6 Hrs Sync Replication with Gold Copy: Recovery Point 12-24Hrs CDP Time based CDP: Time indexed, but no event driven recovery points CDP: Unlimited recovery points with application-aware I/O bookmarks Patch A Patch B Patch C Patch G Hot Backup VSS 2

3 Continuous Data Protection for DVR-like Rollback Snapshots and Clones Creates copies like time-lapse photographs Continuous Data Protection Change-based VIDEO CAMERA with DVR-like roll back capabilities Either space efficient changebased snapshots for backup offloading Or full copies or clones for test and development with minimal production impact Journal every change made and set the window for the amount of time to record 3

4 Recover Point Components and Topology EMC Application servers Layer 2 Fibre Channel SAN IBM HDS LSI HP Heterogeneous storage RecoverPoint appliances Fibre Channel/ WAN Application servers Accesses data that needs to be replicated Heterogeneous storage Source or target for replicated data RecoverPoint appliance (RPA) Connects to LAN and Fibre Channel (FC)/WAN for replication management and replicating data over FC/IP Connects to Layer 2 FC SAN for storage access RecoverPoint appliance cluster A group of inter-linked RPAs, working together closely, to provide replication services RPAs in a RecoverPoint cluster are called nodes Host, Fabric, or EMC Storage splitter WAN bandwidth management Reduce WAN bandwidth by up to 90% through deduplication, compression, and write-folding 4

5 RecoverPoint/CDP Roll back production applications to any point in time RecoverPoint write splitter Intercepts all server writes (block-level) Resides on the VNX series array (or optionally on host or Virtual Machine) iscsi SAN Array-based write splitter runs on VNX series, no host agent required FC SAN EMC RecoverPoint RecoverPoint Appliance Runs RecoverPoint software, offloads replication processing for better scale and performance Performs protection and recovery for VNX Unified block storage Handles monitoring, management, and control Attached to FC for storage access or can be directly attached to FC ports on VNX series Maintains write-order fidelity Journal Tracks all data changes to every protected LUN Utilizes bookmarks for application-aware recovery 5

6 RecoverPoint CDP, CRR & CLR Data Protection VMware ESX Server VMware ESX Server VMware ESX Server VMware ESX Server SAN RecoverPoint WAN/SAN RecoverPoint SAN Third- Party Third- Party SAN/NAS Storage Local Journals Remote Jurnal SAN /NAS Storage Local continuous data protection (CDP) Transactional, any point-in-time recovery Out-of-band, network-based architecture Bookmarks for application consistency Policy engine to map to existing SLAs Continuous remote replication (CRR) for DR Concurrent local and remote (CLR) replication Bi-directional sync and async replication Remote target replica processing (DR testing) WAN bandwidth reduction and compression 6

7 RecoverPoint/Local Protection Process Continuous Data Protection (CDP) 1. Data is split by the VNX splitter and sent to the RecoverPoint appliance 2. VNX splitter 3. Writes are acknowledged back from the RecoverPoint appliance 4. The appliance writes data to the journal volume, along with time stamp and application-specific bookmarks / A / C / B r A r B r C Production volumes Replica volumes Journal volume 5. Write-order-consistent data is distributed to the replica volumes 7

8 RecoverPoint/Remote Protection Process Continuous Remote Replication (CRR) 1. Production Data sent to storage and split by embedded VNX splitter 3. Writes are acknowledged back from the RecoverPoint appliance 2. VNX splitter 6. Data is received, uncompressed, sequenced, and checksummed 7. Data is written to the journal volume / A / C / B Local site 4. Appliance functions Fibre Channel- IP conversion Deduplication Data reduction and compression Monitoring and management 5. Data is sequenced, checksummed, compressed, and replicated to the remote RecoverPoint appliances over IP or SAN r A r B Remote site r C 8. Consistent data is distributed to the remote volumes Journal volume 8

10 Dynamic Sync to Async Mode Change for Best Protection & Performance Automatically switch from sync to async based on bandwidth or latency degradation Minimize bandwidth requirements for remote replication Maintain performance and protection during I/O spikes Fully integrated with vcenter SRM to automate failover New replication flexibility for EMC and non-emc arrays I/O burst impacts performance or protection Mode change maintains performance and protection Bandwidth Utilization Source 6:00AM 5:59AM Target 10

11 Dynamic Switching Between Synchronous and Asynchronous Set in a policy for each consistency group Switch based on latency Synchronous replication Switch based on production throughput Throttle production application 11

12 Journaling for Application-Aware Recovery Journal includes data plus metadata Time/date Identifies the time image was saved Bookmarks: System-generated group bookmarks (e.g., failover snapshot) User-generated bookmarks Other EMC product bookmarks (e.g., EMC Replication Manager) System-event-generated bookmarks Microsoft SQL Server (VDI) Microsoft Exchange (VSS) 12

13 Understanding Data Consistency Grouping for a Consistent View Allows application recovery to be tiered by service level Multiple volumes per group Mixed recovery point objectives within same infrastructure OE Group 1 CRR Provides independent replication controls Recover by group, locally or remotely Start/stop by group Enables grouping of optimization CRM SCM CDP CDP Group 2 CRR CRR Importance Resource usage Group 3 CRR Recovery point and recovery time objectives 13

14 Integration with VMware vcenter Site Recovery Manager (SRM) Simple, automated disaster recovery set-up, testing, and failover Production vcenter Server SRM SRA Virtual Machines VMware Site Recovery Manager Disaster Recovery SRA SRM vcenter Server Virtual Machines Protect and recover a single virtual machine or the entire server Protect virtual environments with local and/or remote point-in-time recovery VMware Infrastructure Servers Heterogeneous Storage EMC Adapters for VMware vcenter Site Recovery Manager VMware Infrastructure Servers Heterogeneous Storage Easily test recovery while keeping production data running Compress data, optimize bandwidth with RecoverPoint (up to 10 times) RecoverPoint 14
