What If You Could . . .

Backup and restore your VMs instantaneouslyEasily protect all your virtualised data with DRSave 50% on your storage, power, cooling, and spaceReduce virtual server and virtual desktop data, enabling 50% space savings, or moreAutomate your most labour-intensive data management tasksClone and provision storage as quickly as your VMsDo all of this with one architecture in any environment


What can be achieved

Increased efficiency:1356 physical servers to 102Power savings of ~1MWSpace savings of 293 racksOver 4000 ports saved

Increased capabilities:Activation times down to minutesBackup went from 96 hours to 31 minutesEnabled “capacity on demand” business model

Virtual Machines perceive full-sized virtual disks. Optionally, virtual disks themselves are thin provisioned.

Make sure you can grow your underlying aggregate to support the space you’ve provisioned!


Fast and Efficient Copies: Cloning for Identical Servers

Many serversMany copies of data

Before Virtualisation After Virtualisation

Many “virtual” serversMany “virtual” copies of data

Enabling NetApp technology: FlexClone®

Dev 1 Dev NDev 2

100% additional storage for each VMware clone

The traditional challenge with creating many Virtual Machines

VMware clones are based on templates

Deployment consumes time = size of template

Are managed serially – one at a time

Consume storage – 100% redundant

VMware template clones

• Clones are 100% identical

• Including OS and applications

• Clones consume storage equal to size of template

By design VMware® environments are very redundant


Production Data Deduplication

Dedupe removes redundant data

• Supports FCP, iSCSI, & NFS

• 50% – 70% storage reduction

• >90% with VDI

NetApp deduplication provides the same benefits as the VMware shared cached memory functionality

Before Server Virtualisation…

Backup Challenges

– Systems to be virtualised had low CPU & memory utilisation

– Made them ‘low hanging fruit’ for virtualisation


Before Server Virtualization…

Backup Challenges

– Systems have high CPU & memory utilization when backup operations are running


After Server Virtualisation…

Backup Challenges

– Multiple VMs share CPU & memory– Sharing reduces infrastructure costs


After Server Virtualisation…

Backup Challenges

– Traditional backup conflicts with goal of virtualisation


After Server Virtualisation with NetApp Storage…

Backup Solution

– Backup is an integrated component of virtual storage– Policy driven, automated– Zero performance impact– Application integration (SQL, Exchange, Oracle, etc)
