Storage Design6
Infrastructure Gotcha's Network InterconnectLimited number of storage Controllers
Performance is King Random steady state I/O attributes of Virtual Desktop (results in excess spindle count)Reads are Easy, Writes are HardOverprovisioning of storage required for acceptable performance (expensive)Network interconnect often becomes a bottleneck

IO Dispersion 7
Tiered storage is defined with a single aggregate, but volumes are broken down into the following six different types: • Operating System Template • Master Replica • Parent Replica • Linked Clone – Composed of Delta Footprint + Log + User Data Disk. • Persistent Disk – Optional, and ideally not used for Stateless Desktop • Disposable Disk

IO Dispersion 8
Storage tiering – Manual vs Automatic • Replica on SSD storage
• Offload operations• C:\ - System disk• Profile -View Virtual Profiles• User Data –Folder Redirection for Home Directory• Applications –Streamed ThinApp

Security Considerations – Authentication 27
• Password• Smartcards• Kiosk Mode• Radius• Copy and Paste• USB – Allow or Disallow

Application Deployment 28
• Do What Works For You • ThinApp, XenApp & App-V – The Bubble
• Stream or Not to Stream• Compression • ThinReg vs SDK
• Unidesk & Mirage – Layering • ProfileUnity – GUI & Scripts• Horizon• All of the above will have impact on
storage & performance
29

User Personalization 29
• Test, Test, Test • ViewPersona - RTO• Unidesk & Mirage – Layering • ProfileUnity• All of the above will have impact on
storage & performance

Persistent vs Non-Persistent30
• Quick logon• Like a regular desktop to
maintain• Easier to find the desktop• Infrastructure people will love • Hardier recovery
Persistent Non-Persistent• Delete instead of fix• Spare Pool• Survival of ADAM errors• Larger impact on IO• Profile Management
Needed• InfoBlox • Other considerations
• Pool Size• Power On/Power Off
