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
