VDI-in-a-Box is simple to deploy, manage and scale
Reduce VDI infrastructure costs
VDI-in-a-Box eliminates over 60 percent of traditional VDI infrastructure by providing integrated
connection brokering, desktop provisioning, load balancing and user profile management, and
leveraging industry-standard servers with direct-attached storage instead of expensive SAN
storage. Centralized administration and single-instance management lower desktop
management and support costs by up to 80 percent, and image storage costs by more than 60
percent. IT can maintain one master copy of desktop images while preserving the
personalization of user applications and data, dramatically reducing management overhead.
Deploy personalized virtual desktops for every user
Users can install their own applications, set up individual profiles and store their data. IT
administrators can update and manage these personalized desktops just like pooled desktops
by updating and managing the single master image from which they were generated.
Start small and scale on-demand
A deploy-as-you-grow model gives organizations the flexibility to start small and add more off-
the-shelf servers as needed. The hot-pluggable VDI-in-a-Box grid can be reconfigured on
demand without having to turn off a production grid; the desktop administrator simply adds a
hypervisor-equipped server and answers two questions, and the grid automatically updates the
server with all the necessary software and data, then brings it online.

Increase service levels with built-in high availability
Using the N+1 model, the VDI-in-a-Box grid architecture delivers built-in high availability
without shared storage, connection brokers or external load balancers. In IT environments
configured for Microsoft® Active Directory® failover, VDI-in-a-Box will default to a backup Active
Directory server when a primary Active Directory server fails, increasing availability. Grid-wide
virtual IP addresses ensure that the entire grid is accessible by one highly available virtual IP
address.
Simplify desktop virtualization with easy setup and management
VDI-in-a-Box can be deployed in hours, including built-in, policy-based dynamic desktop
provisioning, load balancing and connection brokering. A grid architecture automatically shares
configuration and desktop images, and enables management of all servers as a single entity, so
IT can focus on managing centralized desktop images instead of individual endpoints. A wizard-
driven, point-and-click user interface abstracts virtualization details so a Windows administrator
can set up and manage virtual desktops without any virtualization, SAN or datacenter expertise.
The desktop agent is automatically installed whenever a master image is created or updated,
saving administrators time.
Provide a high-definition user experience
Built-in HDX technology ensures a high-definition, high-performance desktop experience for
virtual desktop users anytime, anywhere, on any device. Integration with Citrix user profile
manager customizes the user experience by delivering personalized virtual desktops. VDI-in-a-
Box supports multiple data stores to offer better virtual desktop density by overcoming the
input/output operations per second (IOPS) challenge with small, high-IOPS SSDs. The three data
store arrangement with SSDs and regular SAS disks offers an even better user experience while
reducing cost per virtual desktop. The optimization pack for Google Earth™, a 3D rendering
application, eliminates the need for a GPU to provide high-resolution graphics for Google Earth
while providing a good user experience.
Ensure high levels of security, compliance and data protection
Nothing is stored on the endpoint, so data is never at risk in the event of a lost or stolen
endpoint device. Single sign-on lets users connect securely to their virtual desktops via VPN.
Users and computers can be placed in specific Windows domains to enforce more stringent
relationships between users and their desktops as needed. A network time protocol (NTP)
interface lets IT time stamp every log entry, aiding regulatory compliance.
Choose from industry-leading hypervisors
An open architecture allows many options for platform and protocol. VDI-in-a-Box is available
on Citrix XenServer, Microsoft® Hyper-V® and VMware vSphere™ hypervisors. It is also protocol
agnostic, supporting both HDX and Microsoft® RDP technologies.

Top five considerations for businesses looking to simplify virtual desktops
1. Cost
No matter what size your organization, make sure you factor in both the hard and soft (direct and indirect)
costs associated with VDI implementation in order to come up with an accurate total project cost. In particular,
consider the following: Infrastructure costs for production use with high availability. You cannot afford to take
chances with the availability of your VDI desktops. After all, VDI is supposed to improve agility, mobility and
efficiency—not leave large numbers of users at the mercy of a single point of failure. Make sure you
extrapolate beyond the pilot deployment to assess the costs associated with deploying a VDI that can support
high availability and scale on demand in a production environment. Assess upfront the total cost of the
physical servers, shared storage such as a storage area network (SAN), load balancers, connection brokers,
management and provisioning servers and any other infrastructure needed for your production deployment.
Upfront costs. You probably want to start small and grow incrementally. Traditional VDI solutions are not cost-
effective on a small scale because they require a large fixed upfront investment which can only be cost
effective for several hundreds of desktops. Consider both the ultimate size of your planned deployment and
whether it will take place in phases. Many companies refresh desktops when PCs break or become obsolete,
and have pre-allocated budget for this. If you plan to re-purpose such budgets to start your VDI deployment,
check that the upfront investment required by the VDI solution you’re considering fits within your budget
constraints. Cost of resources. Estimate the cost of the expertise needed to deploy and manage the VDI
solution. Does your team have expertise in desktop and Windows® administration, storage and SAN,
virtualization management and high-end networking? Would you rather have a Windows/desktop
administrator set up and manage virtual desktops without significant retraining on other components and
technologies?
2. Simplicity
Traditional desktop virtualization deployments require enterprise resources and expertise, and typically take
weeks to months to complete. This can be a challenge for non-enterprises that are looking for implementation
times in hours or days. Calculate the complexity of the proposed VDI solution carefully, looking past the proof
of concept to the time and resources it will take to roll out virtual desktops in production. As you evaluate the
number of hardware and software components the solution will require, bear in mind that as the number of
components in a solution increases, the longer it will take to diagnose and debug any issues that arise. The
more complex a solution, the greater its number of potential failure points, which decreases overall reliability.
Notice, too, the number of editions (trims) of VDI solution that your vendor offers and which one you’d need
for production-quality, highly available virtual desktops. As you size up each component, consider the
resources that it might require, and investigate whether you’d need new staff with a specialized skillset to
install and manage it. You might also find you’d need a separate crew to manage the whole solution.
Thus, do focus on just how simple is the VDI solution under consideration. Most companies do not have
wherewithal to handle a complex VDI solution.
3. Scalability and high availability
Plan from the outset how you can scale the solution over time. If the solution relies on shared storage, scaling
may create bottlenecks such as “bootstorms” that you can only overcome by expensive over-provisioning with
highspeed interconnects and higher-end SANs. Look instead for a solution that can scale in cost-effective steps
to match your needs. Enterprises are used to overprovisioning costs, but if you are not, consider the budget
impact of scalability-related overprovisioning. Not all VDI solutions provide high availability (HA) out of the
box, and if HA is not built in, you will need to re-architect your implementation as you scale to ensure
redundancy. Traditional VDI architectures require you to set up redundant connection brokers, management
servers, clustered SQL databases and high-speed interconnects to deliver HA. For non-enterprises, the simplest
and most predictable approach is a VDI solution that has HA built-in.

4. End-user experience
To help ensure your users are happy with their virtual desktops, take the time to first understand their
workloads and evaluate how a particular solution will fit their needs. Factor in the networks they might
connect from and check whether the protocol is mature and can support various end-point devices such as
tablets and mobile phones and the printers, peripherals that your organization uses. Different VDI solutions
rely on different protocols to stream virtual desktops to users, and these vary in their support for multimedia
redirection, USB and peripheral devices, graphics and WANs. Not all have the ability to adapt dynamically to
network and end-point conditions.
5. Openness of architecture
In evaluating VDI solutions, consider whether they are open enough to offer you options and hence flexibility
in protocols and virtualization technologies. Are you required to adopt virtualization technology from one
single vendor in order to deploy a particular VDI solution? Proprietary architectures could require you to spend
time and money retraining your staff in the new technologies. Beware of vendor lock-in, which can lead to
your paying more over time. VDI solutions with open architecture will easily blend into your infrastructure
thereby removing any technology learning curve and expense associated with that.
