Leveraging Stretched Clusters for Business Continuity2

FalconStor | Our Vision and MissionFalconStor VisionOptimizing Access to Data …Anywhere

FalconStor Mission Simplify and Optimize Data Movement, Storage and Protection…Everywhere



FalconStor: What we Do

Business Agility via Intelligent Data Management

• Information Mobility

• Business Continuity

• Protection / Recovery

• Optimized Single Instance Storage / Archives

Intelligent Abstraction (IA) with Data Service Optimization



What is Intelligent Abstraction?

“Intelligent abstraction is the function of de-coupling application data from all physical constraints while enabling

policy based movement, storage, and protection of information assets”

FalconStor = Intelligent Abstraction



Why Intelligent Abstraction is Important

IA significantly improves availability of IT services

• Business expectations: Service Up = $$

• Disasters and Outages =– Loss of Service– Loss of Revenue

• Service Recovery is much more than just remote-copy

The Issues

• BC/DR Consumes much of the IT budget• Complex, error-prone, and time consuming• Difficult to keep current and consistent• Different vendors for each platform• Different procedures for each platform• Long service recovery times not meeting SLA’s• Easy to recover data, but not complete services

Site A Site B

• Metropolitan Distance ( < 60Km)

• Instant failover with no downtime or data loss

• LongWave FC or DWDM

• Synchronous mirroring

• Low latency required

• Uses any existing certified storage

• Any Distance

• WAN-optimized replication

• Automated rapid recovery

• Asynchronous replication

• Latency not an issue

MicroScan WAN-Optimized Data Replication

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

• FalconStor solutions scan the changes at a 512 byte level and replicates onlythe changed data– Up to 90% less data.

Equivalent to 10:1 dedupe without deduping!

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 solutions send only the truly changed sectors.

512 byte

Disk sectors



Integrated Continuous Protection Eliminates Backup• Continuous data capture with multiple options for historical

views. Data automatically mirrored or replicated offsite.• Combines TRUE CDP journaling with NEAR-CDP

snapshots for any point recovery– Up to 1000 snapshots per volume

Full Journaling: 4 hours

Hourly Snapshots:

24

Daily Snapshots: 7

Monthly Snapshots: 5

Example

• Snapshots can be scheduled as well as created ad hoc• Leverage snapshots for Test/Dev (no storage required)• Create readable/writeable view from any point in time• Snapshots always bootable for Instant recovery



Integrated Data Archiving if Required• Mount CDP snapshots• Use existing backup server to move data to dedupe repository or

tape – Does not impact primary disk or host– Eliminates backup software agents from servers

• Snapshot mounting is automated by the HyperTrac™ Backup Accelerator system

• Increase backup speeds up to 1000% compared to LAN backup model

Business Benefits

• Intelligent Abstraction with built in continuous protection simplifies protection and eliminates backups

• One logical site• Disk becomes a commodity• Integrates with applications for

reliable recovery• All data always protected• No downtime



Why a Stretched Cluster?

• Zero downtime, No data loss• Automated Failover and Failback• Best-in-class RTO/RPO• May become a requirement for cloud providers

and MSP’s



Planning a Stretched Cluster• Typically only mission critical applications need to be included

– Ensure you have enough bandwidth for the Traffic across the link

• 2, 4, 8,10,Gb etc.

– Do you need resilience? – 2 links is better

– Define the right extension based on distance: Dark Fibre, DWDM etc.

– Obtain the true distance of the extended link. Not the A to B distance as Fibreand circuit providers often have longer distances

– Get the provider to measure the Latency figures for the main circuit and any ‘standby’ links they may use

• Assure application I/O response time requirements can be met (latency)

• Check that any application server clusters being deployed support being ‘Stretched’ (quorum resource, etc.)– Ensure Best Practices are adhered to



Latency Estimation

Kilometers Miles Latency in ms5 3.11 0.02510 6.21 0.0520 10,80 0.150 31,07 0.25100 62.14 0.5300 186.41 1.5

Latency = distance/200,000

The speed of light in fibre is about 66% of the speed of light in a vacuum: 200,000 km/s. The one way delay for 100km is 100/200 000= 0.5ms
