The world has changed…and moved on – THANK
GOD !

How much of our IT lives have changed?

Paying Attention? Quick Poll !!
• How many people in the audience have a Smart Phone?• How many people in the audience
have a tablet of some sort?• How many people in the audience
have a laptop?• How many of you have used ALL 3
today already ?

Background: Six Years of VDI Began as “Windows XP on VMware”
Basic Connection Brokers kinda stunk
Limited Use Cases…Cool Factor…– Lead by the VMware Infrastructure
Team
Lesson Learned: Capacity requirements grew too fast, and increased the cost to scale out beyond the POC or initial Pilot
13© Copyright 2012 EMC Corporation. All rights reserved.
Background: Ecosystem Solutions Addressing Capacity Concerns…
– Citrix Provisioning Server, VMware Composer
Solving one problem creates several more…
– Roaming Profiles & User Data– Application Distribution & Virtualization
New Lessons: A completely different management strategy is required…and the old ways don’t go away

Important Items for Proper Sizing
Read / Write ratios
Linked-Clone vs. Persistent users
Concurrency of Logged in users
Login and Logout behaviors of the users
Steady State / Normal IOPS

VDI Technology Overview
VMware View– View Composer
Citrix XenDesktop– Provisioning Server (PVS)– Machine Creation Services (MCS)– Personal Virtual Disk (pvDisk)
16© Copyright 2012 EMC Corporation. All rights reserved.
CITRIX: PVS Storage Mapping
Master Image– Stored on or “behind” the PVS
Server– Streamed to the guest via the
network
Write-Cache (aka “Linked-Clone”)– One created per desktop
17© Copyright 2012 EMC Corporation. All rights reserved.
VMware View: Composer Overview
View Manager works with View Composer
– Composer manages the “Linked-Clones”
Persona at the array or network levels
18© Copyright 2012 EMC Corporation. All rights reserved.
VMware View: Storage Mapping
Replica Images created from a Master Image
Replicas can be placed on specific datastores
Linked-Clones are related to a replica
19© Copyright 2012 EMC Corporation. All rights reserved.
Background: Don’t Forget Performance
User Experience was the LAST thing to be considered…
– Storage Performance is the #1 Culprit
FAST, FAST Cache, and spindle count solve that problem…
20© Copyright 2012 EMC Corporation. All rights reserved.
Importance of Image Optimization Each desktop creates unique
storage IO
Optimize the desktop– Remove unneeded features– Offload antivirus w/ vShield
Endpoint
Huge factor in shaping user experience, performance & cost
21© Copyright 2012 EMC Corporation. All rights reserved.
Here Comes the IO Storm
IO Storms are the peaks that occur in the VDI storage lifecycle
Each “storm” has it’s own attributes that make it nasty
– Boot Storms – Read Intensive– Login Storms – Write Intensive– Logout Storms – Read Intensive
22© Copyright 2012 EMC Corporation. All rights reserved.
Background: The way to go is… For years, the entire industry has
been telling customers the same thing:
NON-PERSISTENT desktops will save you money on
infrastructure & management
23© Copyright 2012 EMC Corporation. All rights reserved.
Is a non-persistent desktop cheaper? Unless you transition ALL of your
desktops to the new model, you now have TWO desktop management strategies to maintain
Modernizing or Virtualization applications is not cheap…and is very time consuming
Productivity WILL suffer for most users as they can’t work like
they always have
24© Copyright 2012 EMC Corporation. All rights reserved.
Non-Persistent isn’t ALL bad… When a non-persistent desktop is
the right choice, it’s great…– Call centers– Task Workers– Education and Training– Contractors and Remote Workers
Yes, it can be a cheaper choice…– when it’s the right fit
25© Copyright 2012 EMC Corporation. All rights reserved.
Why Persistent will never go away… Cheaper than the alternative in the
long run
Easier to manage and support
Less complexity to design and maintain
Leverages the existing management practice
Users will always DEMAND persistence
26© Copyright 2012 EMC Corporation. All rights reserved.
Why New All-Flash Arrays make sense?
INLINE deduplication…– Persistent and Non-Persistent
desktops consume the SAME capacity
With ALL-FLASH capacity…– Performance issues at the array level
go away
No need to create separate infrastructures to host persistent and non-persistent desktops
27© Copyright 2012 EMC Corporation. All rights reserved.
Why does this make sense? Manage your physical & virtual
desktops the same way!– Don’t design around PVS, MCS, or
Composer– Forget about roaming profiles– Keep distributing and updating
your applications the same way

End User Computing Best PracticesThe Keys To Success
Develop A Holistic EUC Strategy– It’s MORE than VDI
Define A Governance Model
Establish A Technology Stack That Works … For You!
Assessment And Discovery Utilizing Automated Tools
Focus On The User - Establish A Comprehensive User Communication & Training Plan
