• A storage hurricane is on the way in the shape of VDI

• What's driving VDI adoption?

– Desktops are aging – some are 4 to 5+ years old.

– Windows 7, Security & Desktop Disaster Recovery

are some of the key drivers in the move to VDI

architecture.

• Desktop Group Storage Group ??

• Storage infrastructure is typically the # 1 reason VDI

deployments have issues.

Typical Challenges to Contend With…

Distributed workforce

• Mobile & remote workers

• Outsourcing & off-shoring

• Contract Workers

Limited control of PCs

• Patch compliance

• Security

• Regulatory compliance

Focus on PC hardware

• Many makes & models

• Refresh cycles

Management complexity

• Deployment

• Support

• Security

VMware View - Addressing the

Challenges…

6© Copyright 2010 EMC Corporation. All rights reserved.

New Challenges Arise

• Must reduce TCO per user

• Current infrastructure designed for server workloads

• Large number of VMs to manage

• Aggressive and somewhat unpredictable performance profiles

• Small changes have a big impact (10 IOPS per desktop multiplies)

• Availability and performance requirements increase

~10 IOPS

10 GB

~1200 IOPS

1.2 TB99.999%

99%

EMC Addressing the Challenges…

• Store more Efficiently

• Dynamic, Flexible Infrastructure

• Protect the migrated user data

• Secure user access

What do customers

ask for when they

are deploying

VMware View?

Solving the big barriers….

Step 1 = Lowering the cost of storage

by… A LOT.

10© Copyright 2010 EMC Corporation. All rights reserved.

First – what about capacity?1000 users, 10GB per desktop = 10TB – right?

Wrong…

Operating System– View Composer = savings capacity requirements for OS

storage• 60:1 savings (non-persistent)

• 2:1 - 5:1 savings (persistent)

Applications– Thin App = 50:1 savings for app storage

• Assuming only 50% of apps can be virtualized

Storage– Dedupe/Compress + Archive = savings on user data

storage• 4:1 savings (being conservative)

11© Copyright 2010 EMC Corporation. All rights reserved.

Is the problem solved?

10:1 capacity reduction means all 1000 users can

run on 1TB of storage – right?

Wrong…

1TB of storage fits on one spindle

How many hard drives are in 1000

desktops/laptops?

How do we solve THAT problem?

12© Copyright 2010 EMC Corporation. All rights reserved.

The Challenge• Architecting a View Environment to size for BOTH capacity and

performance at scale when leveraging Linked Clone or Snapshot Technology

The Analysis• 1000 x 10GB boot images = 1TB

– >80% capacity savings

• 8-10 iops per user ≈ 10,000 iops

The Result• at scale, data reduction technologies + EFD saves you $$$

How do you leverage EFD most efficiently?
