Why EUC today?

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

This is the past…lets not dwell on it !

This is the future!….access anytime/anyplace

End User Computing Is No Laughing Matter

How much of our IT lives
have changed?

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

What Apps can you not live without?

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

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)

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

VMware View: Composer Overview
View Manager works
with View Composer
– Composer manages the
“Linked-Clones”
Persona at the array or
network levels

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

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…

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

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

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

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

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

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

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

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 Practices
The 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
