Chapter 1: Executive Summary
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 uses 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 the vSphere 4.1 feature helps you save
memory and therefore 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 of 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.

Terminology
Term
Description
Block data
compression
EMC unified storage introduces Block data compression, which allows
customers to save and reclaim space anywhere in their production
environment with no restrictions. This capability makes storage even
more efficient by compressing data and reclaiming valuable storage
capacity. Data compression works as a background task to minimize
performance overhead. Block data compression also supports thin
LUNs, and automatically migrates thick LUNs to thin during
compression, freeing valuable storage capacity.
EMC FAST Cache
This feature was introduced early with FLARE® release 30 and allows
customers to use Flash drives as an expanded cache layer for the
array. FAST Cache is an array-wide feature that you can enable for any
LUN or storage pool. FAST Cache provides read and write access to
the array.
EMC Fully
Automated
Storage Tiering
for Virtual Pools
(FAST VP)
EMC has enhanced its FAST technology to work at the sub-LUN level
on both file and bock data. This feature works at the storage pool
level, below the LUN abstraction. It supports scheduled migration of
data to different storage tiers based on the performance requirements
of individual 1 GB slices in a storage pool.

Chapter 2: Introduction
Term
Description
Virtual desktop
Desktop virtualization (sometimes called client virtualization), that
separates a personal computer desktop environment from a physical
machine using a client–server model of computing. The model stores
the resulting "virtualized" desktop on a remote central server, instead
of on the local storage of a remote client; therefore, when users work
from their remote desktop client, all of the programs, applications,
processes, and data used are kept and run centrally. This scenario
allows users to access their desktops on any capable device, such as
a traditional personal computer, notebook computer, smartphone, or
thin client.

EMC VNX platform
The EMC VNX platform 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 on VNX OE for block to optimize performance for the
virtual desktop environment, helping support service-level agreements. EMC unified
storage supports vStorage APIs for Array Integration (VAAI), which were introduced in
VMware vSphere 4.1. VAAI enables quicker virtual desktop provisioning and start-up.
EMC Unisphere
EMC Unisphere provides a flexible, integrated experience for managing CLARiiON,
Celerra, and VNX platforms in a single pane of glass. This new approach to midtier

Figure 1.
EMC FAST VP
Unisphere Summary page
With EMC FAST VP, EMC has enhanced its FAST technology to be more automated
with sub-LUN tiering and to support file as well as block. This feature works at the
storage pool level, below the LUN abstraction. Where earlier versions of FAST VP
operated above the LUN level, FAST VP now analyzes data patterns at a far more
granular level. As an example, rather than move an 800 GB LUN to enterprise Flash
drives, FAST VP now identifies and monitors the entire storage pool in 1 GB chunks. If
data becomes active, then FAST VP automatically moves only these “hot” chunks to a
higher tier like Flash. As data cools, FAST VP also correctly identifies which chunks to
migrate to lower tiers and proactively moves them. With such granular tiering, it is
now possible to reduce storage acquisition while at the same time improve
performance and response time. In addition, because FAST VP is fully automated and
policy-driven, no manual intervention is required to make this happen, so you save
on operating costs as well.

Chapter 2: Introduction
EMC FAST Cache
VNX FAST Cache, a part of the VNX FAST suite, enables Flash drives to be used as an
expanded cache layer for the array. FAST Cache has array-wide features available for
both file and block storage. FAST Cache works by examining 64 KB chunks of data in
FAST Cache enabled objects on the array. Frequently accessed data is copied to the
FAST Cache and subsequent accesses to that data chunk are serviced by FAST Cache.
This allows immediate promotion of very active data to the Flash drives. This
dramatically improves the response time for very active data and reduces the data
hot spots that can occur within the LUN.
FAST Cache is an extended read/write cache that can absorb read-heavy activities
such as boot storms and antivirus scans, and write-heavy workloads such as
operating system patches and application updates.
Block data
compression
EMC unified storage introduces block data compression, which allows customers to
save and reclaim space anywhere in their production environment with no
restrictions. This capability makes storage even more efficient by compressing data
and reclaiming valuable storage capacity. Data Compression works as a background
task to minimize performance overhead. Block data compression also supports thin
LUNs, and automatically migrates thick LUNs to thin during compression, freeing
valuable storage capacity.
Cisco Unified
Computing System
(UCS)
Cisco UCS provides the computing platform purpose-built for virtualization, delivering
a cohesive system that unites computing, networking, and storage access. Cisco UCS
integrates a low-latency, lossless 10 Gigabit Ethernet unified network fabric with

VMware components
Hypervisor
Hypervisor is used to host the virtual desktops. To get most of the features, we
recommend that you use VMware vSphere 4. The vSphere 4 features such as vSphere
API for Array Integration (VAAI), Memory Compression, and Ballooning help to host
more virtual desktops on a host.
VMware View
Connection server
The VMware View Connection server hosts the LDAP directory and keeps the
configuration information of the VMware View Desktop Pools, its associated virtual
desktops, and VMware View. This data information can be replicated to other View
Connection Replica servers. The Connection server also acts as a connection broker
that maintains the desktop assignment. It supports a secure socket layer (SSL)
connection to the desktop using remote desktop protocol (RDP) or protocol PC over IP
(PCoIP). It also supports RSA® SecurID® two-factor authentication and smart card
authentication.
VMware vSphere
vCenter/View
Composer
The VMware vSphere vCenter server helps you manage your virtual machines and
vSphere ESX hosts and provides high availability (HA) and Distributed Resource
Scheduling (DRS) clusters. The VMware vCenter server hosts customization
specification that permits cloned virtual machines to join the Active Directory (AD)
domain. The View Composer service is installed on the vCenter server that provides
storage savings by using linked clone technology to share the hard disk of parent
virtual machines as shown in Figure 4.

Figure 4.
Linked clone
The operating system reads from the common read-only replica image and writes to
the linked clone. Any unique data created by the virtual desktop is also stored in the
linked clone. A logical representation of this relationship is shown in Figure 5.
Figure 5.
Linked clone virtual machine
View Security
server
The View Security server is a different type of View Connection server. It supports two
network interfaces—one to a private enterprise network and the other to the public
network. It is typically used in a DMZ and enables users outside the organization to
securely connect to their virtual desktops.
VMware View
Transfer server
The VMware View Transfer server is another type of View Connection server that is
required when you use the local mode feature. The Transfer server can use the CIFS
share on VNX files to store the published image. The local mode allows users to work
on a virtual desktop disconnected from the network and later synchronizes the
changes with the View environment.
Database server
The VMware View supported database server is used to host the tables used by View
Composer and can optionally store the VMware View events.
VMware View
Agent
VMware View Agent is installed on the virtual desktop template and is deployed to all
virtual desktops. It provides communication to the View Connection server and
enables options for USB redirection, virtual printing, PCoIP server, and Smartcard
over PCoIP.
VMware View
Client
VMware View Client software is used to connect to the virtual desktops using the
connection broker. View Client allows users to print locally from their virtual desktop,
and with the proper configuration, users can access USB devices locally.

VMware View
Admin Console
VMware View Admin Console is a browser-based administration tool for VMware View
and is hosted on the View Connection server.
VMware View
PowerCLI
VMware View PowerCLI provides the basic management of VMware View using
Windows Powershell. It allows administrators to script some basic VMware View
operations and can be used along with other Powershell scripts.
VMware ThinApp
VMware ThinApp is an application virtualization product for enterprise desktop
administrators and application owners. It enables rapid deployment of applications
to physical and virtual desktops. ThinApp links the application, the ThinApp runtime,
the virtual file system, and the virtual registry into a single package. The CIFS share
on EMC VNX file can be used as a repository and to deploy the ThinApp to the virtual
desktops.

Chapter 3: Solution Infrastructure
Processor
The server used in this solution has two quad-core Intel Xeon 5500 processors. The
average CPU load during the test is 9 percent. Therefore, we can run approximately 10
virtual machines per core. One host can run 2 × 4 × 10=80 virtual machines. The Intel
Nehalem architecture is very efficient with hyper-threading and allows 50 to 80
percent more clients. This means it can run 1.5 × 80=120 to 1.8 × 80=144 virtual
machines per host.
While using linked clones, up to eight hosts are allowed in a cluster. Leaving one
node as failover capacity, with seven hosts, we can run 144×7=1008 virtual
machines. One cluster can host 1,000 virtual desktops. Without considering the Intel
Nehalem features, the cluster can host 80×7=560 virtual desktops. To host 2,000
virtual desktops, we need two to four clusters, which are about 128 to 256
processors in total. In a non-VDI environment, deploying 2,000 desktops would
require 2,000 processors.
With hyper-threading, we are able to host 1,000 VMs per cluster and without hyperthreading, we are able to host only 500 VMs per cluster. Thus, we are able to double
the number of hosts per cluster when using hyper-threading. In our solution, we use
hyper-threading with three clusters; one with 1,000 users and other two with 500
users each. The 500-user cluster has extra room for processor intensive workloads.
Table 7 provides a summary of virtual machines per core.

One Windows 7 virtual machine is assigned 1.5 GB of memory. Without using VMware
vSphere 4.1 features, it would require at least 9×8×1.5=108 GB to 18×8×1.5= 216
GB per host. VMware vSphere 4.1 provides features such as Transparent Page
Sharing, ballooning, compression, recognition of zeroed pages, and memory
compression that allows us to overcommit the memory to obtain a better
consolidation ratio.
During the baseline workload, we observed about 540 MB used in active memory.
The memory overhead was 179 MB; the hypervisor used 578 MB for the 48 GB host
and 990 MB for the 96 GB host, and the service console memory was 561 MB. Based
on this workload, we require 103 GB determined by the following calculation:
((9×8×(540+179) +578+561)/1024) = 52 GB to ((18×8×(540+179) +990+561)/1024) = 103 GB
VMware vSphere uses the above-mentioned features before it uses the swap
memory. The FAST Cache on EMC’s VNX series storage platform does provide better
response time compared to swapping the memory to SAS disks. Another option is to
consider having a solid-state drive (SSD) on each host to host the vSwap. This may
impact vMotion and also adds complexity to the environment. It is, therefore,
advantageous to have the swap served by the FAST Cache on the EMC array.

Case
We used 1,536 GB in total for hosting 2,000 virtual desktops. In a typical case, 1.5
GB per desktop will not be available, instead 2 GB will be used, which would require
4,000 GB in total. Still, virtual desktops can provide better boot-up time compared to
that of the traditional personal computer.
Network
Based on the workload, we found one virtual machine requires approximately 18
Mb/s. So, a 100 Mb/s card can support five to six virtual machines per NIC, a 1 GB
NIC can support 50 to 60 virtual machines per NIC, and a 10 GB NIC can support 500
to 600 virtual machines per NIC. The Converged Network Adapter (CNA) running at 50
percent bandwidth can support 250 to 300 virtual machines per CNA.
Note: This is just a rough estimate and we must always watch for the network load
and look for the percent packet drops. If the value is high, check the network
configuration and consider adding another NIC. In this solution, we used two
CNAs per host to provide fault tolerance. For 2,000 virtual desktops, we used
2×8×3= 48 NICs. In a traditional desktop scenario, 2,000 desktops require
2,000 NICs.
Storage
The number of spindles required for hosting 2,000 user desktops is calculated using
both the IOPS requirement and the capacity needed. Based on the workload, we
observed 8.3 IOPS per virtual desktop on average. The maximum and 95th percentile
is based on the time interval of the data. The sizing on the average IOPS can yield
good performance for the virtual desktops operating in a steady state. However, this
leaves insufficient headroom in the array to absorb high I/O peaks. To combat the
issue of I/O storms, there should be two to three times the average to absorb that
load. Table 9 details the IOPS requirement and Table 10 describes the disks needed
by various RAID levels to meet that IOPS.

When considering the storage size of virtual desktops, VMware View Composer
reduces the size required by using linked clone technology. Linked clones are
dependent virtual machines linked to the replica virtual machine. A replica virtual
machine is a thin provisioned copy of the master virtual machine. We deployed a 20
GB hard disk for the operating system to the master virtual machine. The files occupy
13 GB and, therefore, the replica virtual machine disk size is 13 GB.
In the desktop pool, we use a file share on the VNX array to host the user profile and
data. A disposable disk that contains the temporary files and windows paging file is
used to minimize the expansion of delta disks and, therefore, reduces the refresh
frequency to the virtual machine.

VMware View 4.5, VMware View Composer 2.5, and
Cisco Unified Computing Systems—Proven Solution Guide
32
Chapter 3: Solution Infrastructure
The size of a virtual desktop is the size of the delta disk plus two times the memory
size of the virtual machine plus 2 MB for internal disk plus the disposable disk and
log size.
Considering 1 GB for the delta disk, it requires approximately 6 GB for one linked
clone.
VMware View 4.5 supports 512 linked clones from a single replica. To host 500 virtual
desktops, we need 3 TB. With the current VMFS version, the maximum size that is
supported is 2 TB minus 512 bytes. This means that we need to split them into two
datastores. To host 2,000 virtual desktops, we need eight datastores of 2 TB to allow
additional space for growth. Therefore, we need 16 TB in total for the linked clones.
If linked clones are not used, it requires 25 GB per virtual machine in thick format or
18 GB per virtual machine using thin disks.
This solution uses 200 GB Flash, 300 GB SAS, and 2 TB NL-SAS disks. The usable raw
capacities are 180 GB Flash, 268 GB SAS, and 1.8 TB NL-SAS.
With four Flash drives in RAID 10, 360 GB is dedicated for the replica with a RAID 5
mix of SAS and NL-SAS, and it gives 37 TB. With a RAID 10 mix of SAS and NL-SAS, we
have 16 TB. With RAID 10, we use fewer spindles and that data does not grow much
compared to user data.
With a dedicated datastore for the replica, the space that is required on the replica
LUN is approximately 39 GB for three virtual desktop pools. Any data accessed three
times in a given period normally resides in FAST Cache. To maximize the use of Flash,
we elected to use it as FAST Cache. Table 12 describes the drives used in this
solution.

Cisco Unified
Computing System
(UCS) B-Series
Blade Servers
Cisco Unified Computing System
Cisco UCS B-Series Blade Servers are designed for compatibility, performance, energy
efficiency, large memory footprints, manageability, and unified I/O connectivity:
•
Compatibility: Cisco UCS B-Series Blade Servers are designed around multicore
Intel Xeon 5500, 5600, 6500 and 7500 Series processors, DDR3 memory, and
an I/O bridge. Each blade server's front panel provides direct access for video,
two USB, and console connections.
•
Performance: Cisco's blade servers use the Intel Xeon next-generation server
processors, which deliver intelligent performance, automated energy efficiency,
and flexible virtualization. Intel Turbo Boost Technology automatically boosts
processing power through increased frequency and use of hyper-threading to
deliver high performance when workloads demand and thermal conditions
permit. Intel Virtualization Technology provides best-in-class support for
virtualized environments, including hardware support for direct connections
between virtual machines and physical I/O devices.
•
Energy efficiency: Most workloads vary over time. Some workloads are bursty
on a moment-by-moment basis, while others have predictable daily, weekly, or
monthly cycles. Intel Intelligent Power Technology monitors the CPU utilization
and automatically reduces energy consumption by putting processor cores into
a low-power state based on real-time workload characteristics.

36
Chapter 3: Solution Infrastructure
•
Large-memory-footprint support: As each processor generation delivers even
more power to applications, the demand for memory capacity to balance CPU
performance increases as well. The widespread use of virtualization increases
memory demands even further due to the need to run multiple OS instances on
the same server. Cisco blade servers with Cisco Extended Memory Technology
can support up to 384 GB per blade.
•
Manageability: The Cisco Unified Computing System is managed as a cohesive
system. Blade servers are designed to be configured and managed by Cisco
UCS Manager, which can access and update blade firmware, BIOS settings, and
RAID controller settings from the parent Cisco UCS 6100 Series Fabric
Interconnect. Environmental parameters are also monitored by Cisco UCS
Manager, reducing the number of points of management.
•
Unified I/O: Cisco UCS B-Series Blade Servers are designed to support up to
two network adapters. This design can reduce the number of adapters, cables,
and access-layer switches by as much as half because it eliminates the need
for multiple parallel infrastructure for both LAN and SAN at the server, chassis,
and rack levels. This design results in reduced capital and operating expenses
through lower administrative overhead and power and cooling requirements.

Microsoft Windows provides the infrastructure used to support the virtual desktops
and includes the following components:
•
Microsoft Active Directory
•
Microsoft SQL Server
•
DNS Server
•
DHCP Server
The Windows domain controller runs the Active Directory service that provides the

following sections:
•
Considerations
•
VNX for file network configuration
•
Enterprise switch configuration
•
Fibre Channel network configuration
Considerations
Physical design
considerations
EMC recommends that switches support gigabit Ethernet (GbE) connections and Link
Aggregation Control Protocol (LACP), and the ports on switches support copper-based
media.
Logical design
considerations
This validated solution uses virtual local area networks (VLANs) to segregate network
traffic of various types to improve throughput, manageability, application separation,
high availability, and security.
The IP scheme for the virtual desktop network must be designed so that there are
enough IP addresses in one or more subnets for the DHCP Server to assign them to
each virtual desktop.
Link aggregation
VNX platforms provide network high availability or redundancy by using link
aggregation. This is one of the methods used to address the problem of link or switch
failure.
Link aggregation is a high-availability feature that enables multiple active Ethernet
connections to appear as a single link with a single MAC address and potentially
multiple IP addresses.
In this solution, LACP is configured on VNX, which combines eight GbE ports into a
single virtual device. If a link is lost in the Ethernet port, the link fails over to another
port. All network traffic is distributed across the active links. Figure 11 shows the
LACP configuration of the Data Mover ports on the Ethernet switch.

serves as a failover device for the active Data Mover.
The VNX5700 Data Mover is configured with two UltraFlex™ I/O modules with each
consisting of four 1 Gb interfaces. It is configured to use LACP with all Data Mover
ports as shown in Figure 12.

Enterprise switch configuration
Cabling
In this solution, we spread the ESX server and VNX Data Mover cabling evenly across
two line cards to provide redundancy and load balancing of the network traffic.
Server uplinks
The server uplinks to the switch are configured in a port channel group to increase the
utilization of server network resources and to provide redundancy. The vSwitches are
configured to load balance the network traffic on the originating port ID.
We used the following configuration for one of the server ports in this solution:
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
spanning-tree portfast trunk
Data Movers
The network ports for each VNX5700 Data Mover are connected to the Ethernet
switch. The ports are configured with LACP, which provides redundancy in case of a
NIC or port failure.
Figure 16 shows an example of the switch configuration for one of the Data Mover
ports.

Introduction
Enterprise-class FC switches are used to provide the storage network for this solution.
The switches are configured in a SAN A/SAN B configuration to provide fully
redundant fabrics.
Each server has a single connection to each fabric to provide load-balancing and
failover capabilities. Each storage processor has two links to the SAN fabrics for a
total of four available front-end ports. The zoning is configured so that each server
has four available paths to the storage array. Figure 17 confirms that information from
the vCenter interface.

Zone configuration
This solution uses single initiator and multiple target zoning. Each server initiator is
zoned to two storage targets on the array. Figure 18 shows the zone configuration for
the SAN B fabric.

Configure VNX
Home Directory
The VNX Home Directory installer is available on the NAS Tools website and the
application CD for each VNX OE for file release. You can also download the software
from Powerlink.
With this feature, you can create a unique share called “HOME,” redirect data to this
path based on specific criteria, and provide the user with exclusive rights to the
folder.
After installing the VNX Home Directory feature, use the Microsoft Management
Console (MMC) snap-in to configure the feature. Figure 37 shows a sample
configuration.
Figure 37.
Configure the VNX Home Directory feature
The sample configuration shown in Figure 38 shows how to automatically create a
user Home Directory for any user in domain view45 in the Homedirs folder on the
View45 file system.
\View45\Homedirs\<user>
For example, when user1 logs in, that user will see that \\VNXFILE\HOME points to
\View45\Homedirs\User1 on the Data Mover. For user2, \\VNXFILE\Home points to
\View45\Homedirs\User2.

Antivirus scan scenario
Overview
We installed the McAfee Enterprise Virus Scan command line utility on all of the
virtual desktops in our test environment, and executed the script remotely from a
central machine.
Note: Although this is not the preferred way to implement an antivirus scanner in a
VDI environment, the purpose of this test is to simulate a traditional customer
implementation.
This section describes the antivirus scan results when powering up the desktop pools
for each of the three use cases. It includes a results summary graph and graphs
showing individual results from scanning 100, 200, 300, 500, and 1,000 desktops in
each of the three scenarios.
Summary
Figure 71 shows the summary results from an antivirus scan for 500, 300, 200, and
100 desktops for a scenario with FAST Cache and no dedicated replicated LUN.

Login VSI test scenario
Overview
To simulate a real-world user workload scenario, the Virtual Session Index (VSI) tool
version 2.1 was used. The Login VSI workload can be categorized as light, medium,
heavy, and custom. A medium workload was selected for this testing and had the
following characteristics:
•
Simulates normal user behavior and speeds for medium workload
•
It uses Microsoft Office applications, Internet Explorer, Adobe Acrobat Reader,
and zip files
•
The tasks include launching the application, typing, minimizing, maximizing
other application, printing, reading PDF, browsing sites that are flash-based.
This section describes the Login VSI tests for each of the three use cases.
We tested this use case in the following conditions:
Use Case 1: with
FAST Cache and no
• With the Auto Tiering option enabled
dedicated replica
LUN
• With Performance Tiering option enabled
The results of both conditions are shown below.
With the Auto Tiering option enabled
Figure 195 shows the Login VSI test results using the Auto Tiering option.

Summary
EMC’s VNX platform along with VMware View enables customers to host virtual
desktops economically and to minimize the risk of exposure of data. The presented
solution highlights the design guidelines for hosting 2,000 users on EMC VNX5700
and uses advanced technologies like EMC FAST VP and EMC FAST Cache to optimize
the performance for the virtual desktop environment.
Findings
The EMC solution team confirmed 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 is reduced by 25 percent.
•
Having the replica datastore use FAST Cache reduces the virus scanning per
desktop by almost 50 percent.
•
With no dedicated replica LUN and using FAST Cache, the maximum response
time of the simulated workload is lower compared to the other two use cases.
•
By using a VAAI-enabled storage platform, we are able to store up to 512 virtual
machines compared to 64 virtual machines per LUN without VAAI-enabled
storage.
•
Using Flash as FAST Cache for the read and write I/O operations reduces the
number of spindles needed to support the required IOPS.
