Virtualization in China

Gartner’s Storage Fundamentals for Virtualized Environments

VMware, Citrix and Microsoft integration and support

Thin provisioningData Reduction, e.g. De-DuplicationExtensive snapshots

Application synchronization toolsRecovery management toolsBoot volume spawning support

iSCSI and Fibre Channel supportSupport in SAN and storage resource management toolsRemote replication

Failover/back managementAutomated tiering

Support for multiple drive types

4


What If You Could Also . . .Backup and restore your VMs instantaneously

Easily protect all your virtualized data with DR

Save 50% on your storage, power, cooling, and space

Deduplicate virtual server and virtual desktop data, enabling 50% space savings, or more

Automate your most labor-intensive data management tasks

Clone and provision storage as quickly as your VMs

Do this with one architecture in any environment

Cost-Effective Data Reliability

The Problem

Double-disk failure is a mathematical certainty

RAID 5 (single parity disk)

Insufficient protectionRAID 10 (mirrored copy)

– Double the cost

NetApp RAID-DP™ Solution

Protects against double- disk failure

High performance and fast rebuild

Same protection and performance as RAID 10 at half the cost

RAID 5 RAID 6 RAID 10 RAID-DP

Cost Low Low High Low

Performance Low Low High High

Resiliency Low High Med High

Instantaneous Backup, Zero Server ImpactThe Problem

High server utilization

No spare cycles for backups

Tape is slow, complex, & expensive

DR can be difficult to manage

NetApp Snapshot™ SolutionServers run apps, not background processesInstantaneous backup and recoveryLow storage overheadApplication consistent

Traditional Backup Is NOT Practical

Increase Agility with Fast Provisioning

Time-consuming physical copiesSlow to provision or reprovisionManual and complexNot suited for VM provisioning

Instant copies with FlexClone®

Quick provisioning with FlexVol®

Simple commands or policiesIdeal for dynamic VM environment
