The VDI Adoption Stages

VDI VDI VDI VDI
Test Pilot Production Acceleration
- Deploy on - A few hundred - Thousands
a few dozen desktops of desktops - 100,000
desktops - Test - Decide desktops
- Typically technology between VDI, - Reap the
use free feasibility XenApp, others benefits of VDI
licenses - Small - Expect to see - VDI is mission
(VMware, workgroup benefits of VDI critical
Citrix, …) rollout including ROI


VDI Adoption: Test
Focus
Assess & compare technologies
VDI Gain hands-on experience
Test with VDI technologies
- Deploy on Narrow down architecture choices

Typical Challenges

Citrix, …) No major challenges

VDI Adoption: Pilot

Assessment of desktops

VDI Adoption: Production

The Broken VDI Deployment Cycle
Why VDI Assess
Rollouts Fail

- Much focus on early stages Maintain Plan
- Over-confidence in VDI
performance (due to over-
provisioned infrastructure
during pilot)
- Performance issues are
re-mediated after the fact
Re-
- Manual process can’t scale Design
Mediate
- Fixing performance issues
downstream is costly
& it doesn’t scale (and is
almost impossible to Deploy
pinpoint quickly)


VDI – How Hard Can It Be?

User
Perspective
“I start my device,
User
log on, and
expect the same
experience I had
with my physical
desktop
environment.”


VDI – It Is Very Hard!
SAN

User
Virtual Desktops
Network

Provisioning

Oracle License Server Profile Server
vCenter

Complexity
Add virtual machines, connection broker, profile server, provisioning server …
… a lot of opportunities for things to go wrong and impact user experience!

A single failure can bring down the entire service – but where is the root cause?
Each VDI element has its own dedicated management tool, but the service
owner has no correlated performance visibility across the VDI environment.

Assess

Lessons

Maintain Plan - Consider inter-
desktop dependencies
Performance from the beginning
Assurance - Mitigate risk of VDI
failure downstream
- Process vs costly
ad-hoc fixes
- Ensure scalability
& deliver ROI

5 Best Practices For VDI Management

Deep
Monitor Visibility
VDI Service, Monitor
Right-Size into
not Silos Users,
for Great Preemptive Sessions
Not Just
ROI Detection VMs
& Alerting


Manage the VDI Service, Not Silos Monitor
VDI Service,
not Silos

Users care about the “service” IT operations teams focus
on infrastructure silos
VDI is slow The DNS servers are
responding well to
queries.

VDI is not
working The User / IT Management
Disconnect
VDI freezes The CPU usage of
often the VMware servers
is ok.

This disconnect is a threat to the success of transformational IT
initiatives & the promise of agility, scalability, and cost savings!


Monitor the VDI Service Monitor
VDI Service,
not Silos

Know when
user access is
slowing


Get 360o Visibility Monitor
VDI Service,
not Silos
Know which tiers
are working and
which are not.

Virtual Server Monitoring Solutions cannot give you 360o visibility.
They focus on the virtualization platform only.


Monitor Every Layer, Every Tier Monitor
VDI Service,
not Silos

There is an alert indicating
The issue looks fine. vCenter
an VMs within the virtual
desktop.
does not show any alert.

The hypervisor looks fine.


VDI Service,
not Silos

Alan’s virtual desktop
has a problem!


VDI Service,
not Silos

Oops – there is 26%
retransmission from
the virtual desktop


Automatic Root-Cause Diagnosis Monitor
VDI Service,
not Silos

Root-cause
The effect of the problem

Deep visibility into every layer, every tier, & service-based
correlation enable rapid/accurate diagnosis of performance issues.


eG Enterprise: VDI Service Manager Monitor
VDI Service,
not Silos

Network? Database?

VDI Service Owner eG Enterprise Manager
Application?
Identify & resolve
problems preemptively,
before users call!

VMware?
Profile Server? Connection Broker?

The Service Manager is a General Practitioner for your VDI.


Understand VDI Usage Right-Size
for Great
ROI

Know who is accessing VDI service


Plan based on Usage Reports Right-Size
for Great

Top users, Top applications ROI

Know usage patterns and trends for effective capacity planning.


Get More Out of Your Investment Right-Size
for Great
ROI
Track user sessions on each server

A few of the servers
are handling most of
the sessions


Know How to Invest Wisely Right-Size
for Great

Find your VDI bottlenecks ROI


Preemptive Detection & Alerting Preemptive
Detection
It is important to have the right metrics & Alerting

Broad Coverage Deep Insights

- LUN queue length
Storage Application Virtual - VM CPU Ready
Physical
Cloud - TCP Retransmissions
Database
Network - Memory leaks
- Profile sizes
Look for domain expertise in VDI, collect the right metrics.
Virtualization

Otherwise, it will be a case of “Garbage in, Garbage out”!


Auto-Baseline Key Metrics Preemptive
Detection
Auto-compute time-of-day baselines & Alerting

Alert administrators when metrics violate baselines

Preemptive detection & alerting lets administrators
see and fix problems before users notice


A Preemptive Alerting Example Preemptive
Detection
& Alerting
A Real-World Scenario:
The domain server goes down, pulling down
the VDI service. Why?
eG’s alarm history provides a clue …

The domain
5 hours earlier, eG has server has failed
alerted about an issue! and rebooted.


Detection
& Alerting
eG’s In-N-Out monitoring of the VM on which
AD is running provides further insights
The Client/Server Run-Time Subsystem (csrss) is
a critical Windows process responsible for
console handling and GUI shutdown.

The csrss process in the
VM is leaking OS handles!


Detection
& Alerting
The fix: Apply the relevant Microsoft Hotfix!


Monitor Users, Not Just VMs Monitor
Users, not
just VMs

Workload of the VM is user-dependent
When a user complains, need to know which
physical server and VM they are on
Need to know who the top users are for
capacity planning
User information required for billing, capacity
planning
Poor user experience impacts VDI success.
So focus on monitoring users, not just VMs!


Users, not
just VMs

When a user calls,
search for the user
Know which ESX/Xen server
he/she is logged on to


Users, not
just VMs

See all the other users
logged on to the same
ESX/Xen host.

See performance issues at the user level so you can fix
and right-size your VDI environment for user satisfaction.
