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
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
.
“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.”
Ruben Spruijt – CTO - Atlantis Computing

COMPLEXITY
“Too complex to
design, build,
maintain”
COST
“It’s not cost
effective -
CAPEX and OPEX”
PERFORMANCE
“User Experience
and Admin
Experience is bad”

GPU capabilities and blazing fast solid state
storage is the standard for a
modern virtual workspace!”

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.”
