Red Hat Enterprise Virtualization sizing guide

EXECUTIVE SUMMARY

You’re looking to deploy a virtualized Windows 7 desktop infrastructure on Red

Hat Enterprise Virtualization (RHEV), but you’re not sure what hardware and networking

resources you’ll need to comfortably support your users—both today and as you grow.

To help you determine the resources you’ll need for your VDI environment—in terms of

RAM, processors, IOPS, and network bandwidth—Red Hat commissioned Principled

Technologies to develop guidelines based on tests we performed in our labs.

This guide presents these guidelines, along with the test results on which they

are based. By understanding the resources that each of your users’ guests will likely

require, you can make informed decisions as you set up your VDI environment.

WHAT WILL IT TAKE TO SUPPORT YOUR USERS?

Red Hat Enterprise Virtualization provides a robust and highly scalable platform

to host, manage, and remotely deliver thousands of virtualized desktops across

hundreds of hosts, resulting in greater hardware efficiency, simplified management,

improved data security, and lower overall infrastructure costs. However, minimal data is

currently available on properly sizing a RHEV for Desktops infrastructure and what an

organization would need to support any given number of users. Principled Technologies

conducted tests based on a Dell™ PowerEdge™ R710 server running Red Hat Enterprise

Virtualization for Desktops 3.0 with the SPICE protocol and the Login Consultants Virtual

Session Indexer 3.0 (Login VSI) benchmark. Our tests simulated the experience of two

types of users—typical office workers and power users who perform more system-

intensive tasks—both using Windows 7 guests.

We set up each office user guest with a single vCPU and 2 GB of vRAM. The

office user set uses the Login VSI medium workload, performing tasks that reflect those

of a typical office user over the course of a workday: reading and writing email

messages, working with spreadsheets, writing documents, etc.

We configured each power user guest with two vCPUs and 4 GB of vRAM. The

power user group uses the Login VSI heavy workload, with tasks similar to those of the

office user, but utilizing a greater number of active windows, faster typing speed, and

higher overall productivity.
