Backup is Broken

• Production system impact• Shrinking backup window• Complex tape management processes• High costs of replication and/or tape shipment• Storage vendor lock-in• RTO from 2 to 24 hours• RPO 18+ hours• Cost, cost, cost!

Enhancing Data Protection

What can we do to enhance data protection?

PAGE 18



VMware Recovery with FalconStor Software

• FalconStor software provides a set of tools to enhance VMware data protection– 100% transactional integrity of data for fast

restores – WAN-optimized data replication to reduce

bandwidth use by 90% or more– Integration with VMware vCenter Site

Recovery Manager – Physical-to-virtual support with Site Recovery

Manager

PAGE 19



Application-centric Protection

Why is application integration important?

Because when you recover, you want your data to look like this

And not like this

FalconStor Snapshot Director for VMware

• FalconStor Snapshot Director for VMware is designed to ensure transactional integrity of data– Data is not in a crash consistent state (it is 100%

transactionally consistent)– No need for lengthy system/DB checking

• Coordinates snapshot process between VMware and FalconStor application-specific and file system-specific snapshot agents

• Runs on the ESX server• Integrates with Site Recovery Manager

Snapshot Sequence of Events

1. SD puts the application into a hot backup modei. Application holds up

processing, flushes cache

2. Application agent informs file system agenti. Agent ensures file system

cache flushed to disk

3. SD initiates VMware snapshot

4. Transactionally complete snapshot taken across the virtual LUN

5. All systems released

Storage Virtualization and Site Recovery

Manager

PAGE 25



The Importance of Site Recovery Manager

• VMware Site Recovery Manager is a critical disaster recovery tool

• Provides automation of DR processes

• Provides automation of DR testing

• Provides reporting for proof of compliance

PAGE 26



Challenges for Site Recovery Manager Implementation

• Site Recovery Manager does not move data by itself, it requires array-level data replication

• Limited number of disk vendor certifications for Site Recovery Manager

• Vendor Storage Replication Adapter (SRA) is platform specific– Need the same hardware on both primary and remote sites– Limited product certifications

• Need to change the underplaying infrastructure at the primary site, the secondary site, or both

• Breaks the virtualization promise of platform independence

PAGE 27



Integration with Site Recovery Manager

• FalconStor Storage Replication Adapter (SRA) integrates FalconStor replication with VMware vCenter Site Recovery Manager

• FalconStor CDP provides replication engine• Virtual disk assignments are automatically coordinated

with associated virtual machines with the help of FalconStor SRA

• Disaster recovery scenarios can be tested at any time– A TimeView™ snapshot image is created and mounted to a virtual

machine being tested

– The virtual machine is started

– Recovery is validated and the TimeView is image removed

FalconStor Storage Virtualization Device

• FalconStor CDP certified for vCenter Site Recovery Manager

• Allows any storage on VMware Hardware Compatibility List (HCL) to be used with Site Recovery Manager

– In effect, FalconStor CDP extends Site Recovery Manager certification to connected disk

• Increases storage array flexibility for VMware Site Recovery Manager, brings support to existing SAN

• Allows Site Recovery Manager testing without breaking the replication stream

WAN Optimization

PAGE 37



Achieving Efficient Data Replication

Deploy sub-block replication to move your data

PAGE 38



MicroScan™ WAN optimization

• Applications and file systems write far more data to disk than actual changes

• FalconStor CDP scans the changes at a 512 byte level and replicates only the changed data– Avoids constant re-

sending of duplicate data

512 byte

= empty disk sector

= data written by application or file system

= sector with actual data change

A typical 8k write of data. Many systems send all 8k or more.

FalconStor CDP sends only the truly

changed sectors.

512 byte

Disk sectors

PAGE 39



MicroScan WAN Savings Example

• Actual user production data for Microsoft Exchange replication– 1300 users, hourly replication from CA to PA– High random-write nature of Exchange is well suited to MicroScan

removal of duplicate data

• Average WAN traffic reduction of 97% with no additional network equipment needed
