Transform your Replication

Miroslav Vrane [email protected]


IT Data Availability Challenges Addressing increasingly demanding business requirements

Protecting business applications without disrupting the business

Replicating large amounts of data without taxing resources

Feeling confident DR process is functioning properly

Cost, cost, and costhow to keep the bill low?

Dont you wish you could have gone back in time to 30 seconds before your data corrupted?


Replication Usage Is Increasing

"Increasingly, organizations of all sizes use replication functionality as their first line of defense within their data protection schemes.

Components and Topology Application servers

Physical or virtual, federated, clustered or stand-alone

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

Connects to storage through Fibre Channel

RecoverPoint appliance cluster A group of inter-linked RPAs, working together

closely, to provide replication services

RPAs in a RecoverPoint cluster are called nodes

WAN bandwidth management Reduce WAN bandwidth by up to 90% through

deduplication, compression, and write-folding

Cap replication bandwidth

Local Replication Process: Continuous Data Protection (CDP)

1. Data is split and sent to the RecoverPoint appliance in one of three ways

4. The appliance writes data to the journal volume, along with time stamp and application-specific bookmarks

5. Write-order-consistent data is distributed to the replica volumes

Production volumes Replica volumes Journal volume

2a. Host write splitter

3. Writes are acknowledged back from the RecoverPoint appliance

2b. Intelligent-fabric write splitter

2c. CLARiiON write splitter

7. Data is written to the journal volume

Remote site Journal volume

5. Data is sequenced, checked, deduplicated, compressed, and replicated to the remote appliances over IP or SAN

1. Data is split and sent to the RecoverPoint appliance in one of three ways

8. Consistent data is distributed to the remote volumes

Consistency Groups for Applications

Consistency Groups (CGs) protect every volume in an application

RecoverPoint ensures write order consistency between production and its replicas

Application recovery can be independent of service level agreements (SLAs)

Independently replicate multiple applications

Organize replicas by application

CG 1

CG 2

Email CRR

CRR CDP SCM

CRR OE

CRR CRM CDP


Distributed Consistency Group

Used for more performance (more write activity) than a single RecoverPoint appliance provides for asynchronous replication

Spread LUN write activity across multiple RecoverPoint appliances

Avoids any bottlenecks caused by a single WAN connection

Replica volumes RecoverPoint appliances:

Primary and three secondary

Application servers

Production volumes

DISTRIBUTED CONSISTENCY GROUP OPERATION DURING ASYNCHRONOUS REPLICATION

SAN/WAN


1. Divide data into 512-byte blocks

2. Determine if blocks are unique or if they exist at replica

3. Compress and replicate only unique blocks

4. Sends data compressed, which is inflated at target

5. Create journal entry with existing and replicated blocks

6. Requires homogeneous GEN4 RecoverPoint appliances
