EMC Infrastructure for Virtual Desktops Enabled by EMC VNX, VMware vSphere 4.1,

VMware View 4.5, and VMware View Composer 2.5

Lower operational and maintenance costs

Solution overview

This solution provides a detailed summary and characterization of the tests performed to

validate an EMC infrastructure for virtual desktops enabled by VMware View 4.5 on an EMC

VNX series platform. It involves building a 2,000-seat VMware View 4.5 environment on the

EMC unified storage platform and integrates the new features of each of these systems to

provide a compelling, cost-effective VDI platform.

This solution incorporates the following components and the EMC VNX5700 platform:

2,000 Microsoft Windows 7 virtual desktops

VMware View Composer 2.5-based linked clones

Storage tiering (SAS and NL-SAS)

EMC FAST Cache

EMC FAST VP

Sizing and layout of the 2,000-seat VMware View 4.5 environment

Multipathing and load balancing by EMC PowerPath

/VE

User data on the CIFS share

Redundant View Connection Manager

Key results and recommendations

VMware View 4.5 virtualization technology meets user and IT needs, providing compelling

advantages compared to traditional physical desktops and terminal services.

EMC VNX5700 brings flexibility to multiprotocol environments. With EMC unified storage, you

can connect to multiple storage networks using NAS, iSCSI, and Fibre Channel SAN. EMC

unified storage leverages advanced technologies like EMC FAST VP and EMC FAST Cache to

optimize performance for the virtual desktop environment. EMC unified storage supports

vStorage APIs for Array Integration (VAAI), which were introduced in VMware vSphere 4.1.

VAAI enables hosts to support more virtual machines per LUN and allows quicker virtual

desktop provisioning. Zero paging recognition and transparent page sharing of vSphere 4.1

feature helps you save memory and thus allows you to host more virtual desktops per host.

Our team found the following key results during the testing of this solution:

By using FAST Cache and VAAI, the time to concurrently boot all 2,000 desktops to a

usable start was significantly reduced by 25 percent.

By using a VAAI-enabled storage platform, we were able to store up to 512 virtual

machines compared to 64 virtual machines per LUN.

With VMware transparent page sharing, we observed memory savings up to 92 GB on a

host with 96 GB of RAM, and with less than 2 percent of it swapping to a FAST Cache-

enabled LUN.

Using Flash as FAST Cache for the read and write I/O operations reduced the number of

spindles needed to support the required IOPS.
