Our Choice

Quest vWorkspace

Microsoft Hyper-V

Microsoft App-V

Phase 1 – Initial Infrastructure

Designed to support 300 Windows 7 Desktops and 200 RDS sessions.

Utilize existing SAN infrastructure.

Virtual Desktops and RDS servers hosted on Hyper-V (managed by SCVMM).

No Desktop replacements – value added only

Infrastructure

What we are Achieving

Desktops as a Service (DaaS).

Centralised desktop management.

Dynamically assembled desktops.

Decisions For Moving Forward

Persistent desktop or non-persistent desktop?

Virtual machine storage, SAN or local disk?

User profiles – folder redirection? Registry capturing? Etc?

Virtualize RDS servers?

Use App-V’s shared cache feature?

Phase 2 – Goals

By the end of March 2011 we will (“should”) have the following;

Support for additional 2500 - 3000 virtual Windows 7 desktops.

Support for additional 1500 - 2000 Remote Desktop Services connections.

300 - 600 Windows 7 RemoteFX “ready” virtual desktops.

Applications streamed using App-V (with shared cache).

Started the next phase of our client hypervisor pilot with vWorkspace integration.

Phase 2 - Infrastructure

2 Additional vWorkspace connection brokers.

2 Additional vWorkspace web portals.

An additional vWorkspace user profile server for redundancy.

An additional MS SQL server for fault tolerance vWorkspace DB.

Utilize existing “intelligent” load balancing appliance for web portal connectivity and use to replace the SSL gateway.

Phase 2 - Infrastructure

50 Additional Hyper-v hosts each with, 12 CPU Cores 120GB Memory 10 146GB 15k SAS drives 4 Network ports 1GB GFX card

This gives us (per server), At least 40 Windows 7 virtual machines with 2GB RAM

60 virtual machines was achievable with acceptable performance 4 – 12 RemoteFX enabled virtual machines 20 RDS sessions

35 sessions with acceptable performance

Advice

DO NOT RUSH INTO ANYTHING.

ONE SIZE DOES NOT FIT ALL.

IDENTIFY USER REQUIREMENTS.

VIRTUAL DESKTOPS ARE NOT VIRTUAL SERVERS!

YOU DO NOT HAVE TO USE THIN CLIENTS!
