Planning • • • • • Determine target deployments Hardware requirements Unsupported Configurations Evaluate Savings Policies

Great: { File share | Virtualization Files | OS deploy files | Backup Files } Maybe: { LOB | Web Servers | HPC |Static content providers } Poor: { Hyper-V hosts | WSUS | SQL / Exchange Servers | Files > 1TB}

VDI!

Overview

Why? • Space! • Caching… • But: Post-processing method! So space needed first

How? • Enable-DedupVolume C:ClusterStorageVolume1 –Usagetype HyperV • Set-DedupVolume C:ClusterStorageVolume1 –OptimizePartialFiles (preview) • In case of low storage: Start-DedupJob C:ClusterStorageVolume1 –Type Optimization
