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

8


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

IO Dispersion – XenDesktop9Tiered storage is defined with a single aggregate, but volumes are broken down into the following types: Machine Creation Services (MCS)• Master Image• Master Snapshot • Host Snapshot• Difference Disk• ID Disk• PvDisk – Optional

Provisioning Services (PVS)• Master vDisk• Difference Disk• Write Cache• PvDisk – Optional Master

Pods & Blocks19

Pods• User/datacenter• Security boundaries• BCDR requirements• Networking• Stretching the Storage\Failure domains

Blocks• Pool Types• Administration• Operational Impact\sizing

Networking23

• Mark the Traffic• WRED FTW!• Scanvenger• USB Traffic• Stay under 80%• 200kps for average user• Application Streaming• Subnet sizing

• /25 /24/ /23 /22

24


Networking - Optimize your Protocol for your Use Case24

• Frame Rate• Bandwidth Floor• Min & Max Image Quality • Audio Limit• Group Policy• Caching

25


Picking your Clients\End Point25

• Managed \ Unmanaged• Security • Repurposing • Future Plans \ Upgrades

26


Security Considerations26

• vShield Manager• App\ Zone• Data Security• EndPoint• Certificates

27


Security Considerations – Authentication 27

• Password• Smartcards• Kiosk Mode• Radius• Copy and Paste• USB – Allow or Disallow

28


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

30


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

31


AD Blunders That Can Hurt You31

http://carlwebster.com/briforum-2012-chicago

• Configure all DC’s as Global Catalog Servers• Missing Subnets in AD

• Closet Domain Controller• DNS Aging & Scavenging • Orphaned DC’s

KEY CONSIDERATIONSFOR SUCCESS

TRADITIONAL ORCONVERGED?

CONSIDERATION 1

34


Virtual Desktop InfrastructureA massive strain on legacy traditional infrastructure

QuickTime™ and aH.264 decompressor

are needed to see this picture.

35


The SSD Band-Aid...that doesn’t solve the real problem

Rapid Desktop Program - for POC’s

• Only 85LBs per Nutanix appliance• Hundreds of VMs• Shrink from half-rack to

transit cases• Turnkey with VDI
