Session Objectives and Takeaways

Business benefits of the Virtual Workspace

Understand challenges of virtual desktop or workstation solutions

Managing costs, complexity and (remote) user experience

User experience is king: benchmarking and scalability

Virtual Workspace Benefits:

Access from anywhere - ‘work isn’t a place’

Data is centralized - no synchronization of large datasets

High performance – leverage GPU, Flash, 10GbE

Security and control - protect intellectual property

Flexible - support BYO and COPE scenarios

Disaster recovery – multi-site and multi-datacenter

Reduce costs – centralized management

Ergonomics – no heat and low noise under the desk

“Modern applications and browsers benefit from

a GPU which massively improves User

Experience. In the near future ‘GPU inside’ will

be the standard for every virtual desktop and

workstation solution.”

Dr. Benny Tritsch – Consultant, speaker, author, geek

.

“The biggest competition isn't Citrix vs VMware,

or AMD vs NVIDIA … it's the physical PC.

The goal is to make the Virtual Workspace

better, cheaper and faster than a PC.”

COMPLEXITY

“Too complex to

design, build,

COST

“It’s not cost

effective -

CAPEX and OPEX”

PERFORMANCE

“User Experience

Experience is bad”

Relevant Network Factors

Bandwidth Latency Packet Loss

Speedof light

Data transfer rate of a

network connection

Delay; amount of time

to traverse a system

Discarding of data

packets (in percent)

Remoting Protocol (RDP/RemoteFX, ICA/HDX, PCoIP, Blast, …)

NOTE: GPUs cannot compensate bottlenecks caused by network bandwidth, latency and packet loss

Performance – used to evaluate an environment's individual areas in terms of speed

Load – subjects the environment to the kind of access and usage rate expected in routine operation

Stress – simulated, mostly benign attacks that generate excessive loads in an environment

Endurance – subjects an environment to a predefined load for some considerable time

Scalability – describes system behavior in relation to access times when the number of users is increased

VDI and Remoting Evaluation Criteria

“We want to know what the actual User

Experience is, not for designers alone but also

for power users and knowledge workers.”

TeamRGE

User Experience – Relevant Factors

Selected host telemetry data points

Remoting protocol features

Remote session performance counters

Client capabilities and media redirection

Network settings

Compression algorithms and media synchronization mechanisms

End-to-end frame rates

User interface response times

.

“Benchmarking never represents the real world –

it only reflects selected aspects.

And frames per second are not the most

relevant quality criteria in remoting scenarios.”

Special thanks goes to Jason Southern from NVIDIA for all the troubleshooting when setting up the test environment

.

“Given the improvements that a GPU provides to

a Virtual Desktop and Workstation it’s not a

question of whether or not you’ll use GPUs but

when you’ll use them.”

Shawn Bass – CTO EUC - VMware
