RecoverPoint

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

Local Protection 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

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

2c. CLARiiON write splitter

3. Writes are acknowledged back from the RecoverPoint appliance

4. Appliance functions

• Fibre Channel-IP conversion

• Replication

• Data reduction and compression

• Monitoring and management

6. Data is received, uncompressed, sequenced, and verified

2a. Host write splitter


RecoverPoint

WAN Deduplication

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

ESX replication

• Mirrors each virtual machine’s writes to the RecoverPoint appliance

• Supports VMFS, physical RDM, and vCenter Site Recovery Manager

• Eliminates need for host agents and simplifies ESX configurations

• Allows applications to span groups of virtual machines or ESX servers

• Simplifies failover and recovery for virtual machines (LUN level)

Reálná implementace RP – 1.část

• Zákazník– Kdo byl (a stále je) zákazník– Prostředí– Požadavky

• Průběh projektu– Příprava

• Sběr informací, highlevel design, analýza, podrobný design

– Implementace• Instalace, základní setup, Konfigurace

– Testování• Bookmarks, různé scénáře zotavení z katastrofy


Reálná implementace RP – 2.část

• Shrnutí– Jeden z nejsložitějších projektů, který byl popsán vyžaduje:

• Cca 1 rok celková doba projektu• Cca 2,5 měsíce čistého času pro práci

– Standardní projekt (2 lokality v jedné zemi) lze provést za 1 měsíc s cca 12i dny čistého času práce.

• Problémová místa a na co dávat pozor– Dokumentace prostředí– Kompatibilita– Nutné downtimy
