About Storage Virtualization



Basic Storage Virtualization

Physical LUN

Slicing Combining

Virtual Drives

Virtual Drive

Physical LUNs



How FalconStor Storage Virtualization Works

• Quickly create virtual volumes from physical disk resources– Physical LUN and virtual

devices up to 16TB– Expand volumes as

needed

• Store VMDK files on virtual volumes

• Securely assign volumes to servers through NSS interface

Virtual disks

Physical disks

FC or iSCSI



Thin Provisioning:Better Storage Utilization

• Create a virtual volume to match size of data provisioning request

• Allocate a smaller amount of actual physical disk space

• Additional physical space allocated automatically as needed

• Reduces wasteful over provisioning of storage

• Saves disk space and power consumption

Storage Virtualization Benefits

• Provides a quick and easy way to provision and share storage resources as needed

• Works with and across any type of storage (SAS, SATA, SSD...) and any brand

• Shared storage enables VMware advanced features (VMotion, VMware HA, Distributed Resource Scheduler)

• Allows easy growth of virtual resources• Space savings through thin provisioning

Migrate Using Storage VMotion

• No down-time migration using Storage VMotion• Move data from SAN or direct attached disk• Reuse old disk as VMDKs are moved



An Alternate Method

• FalconStor Service Enabled Device encapsulates the physical LUN into a Virtual LUN without affecting data

• Even the disk inquiry string is maintained• Enables all storage services

Data Integrity and System Recovery



Enhancing Data Protection

What can we do to enhance data protection?



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 Site Recovery

Manager (SRM)– Physical-to-virtual support with SRM



Application-centric Protection

Why is application integration important?

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

And not like this

CrashConsistentData

TransactionallyComplete

Data



FalconStor Application Snapshot Director for VMware

• The Application Snapshot Director for VMware 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

Storage Virtualization and SRM



The Importance of SRM

• 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



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 SRM• 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



Integration with Site Recovery Manager

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

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

with associated virtual machines with the help of 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 TimeView image removed

FalconStor Storage Virtualization Device

• FalconStor NSS Gateway certified by VMware as a Storage Virtualization Device

• Allows any storage on VMware Hardware Compatibility List (HCL) to be used with SRM– In effect, NSS extends SRM certification to connected disk

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

• Allows SRM testing without breaking the replication stream

WAN Optimization



Achieving Efficient Data Replication

Deploy sub-block replication to move your data



MicroScan WAN optimization

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

• NSS 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. NSS sends only the

truly changed sectors.

512 byte

Disk sectors



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
