Citrix Solution

Citrix Presentation Server (PS) enables users to potentially save large sums of money on management costs and to

minimize data security risks by installing all Windows applications in the data center and virtualizing or streaming them to

end users over the network.

It allows you to deliver applications quickly to remote users without leaving the data center, by using state-of-the-art

application streaming and application virtualization technologies. It eliminates the need to install or manage applications

on individual user devices, helping to make application testing, provisioning, management and support easier and less

costly.

Presentation Server helps you prevent data from leaving the data center without explicit authorization, supporting

regulatory compliance and security objectives. Built-in endpoint scans and policy controls take into account each user’s

role, device characteristics, and network conditions to determine which applications and data they are authorized to

access. Integrated single sign-on and a secure SSL VPN gateway for remote access enable a “one password, one path”

approach to application and data access.

Presentation Server greatly reduces network bandwidth requirements through application virtualization techniques

perfected over the past 15 years. PS greatly reduces network bandwidth requirements and mitigates latency issues,

because with virtualized applications only mouse movements, keystrokes, and screen updates traverse the network. Even

data-laden and graphics-heavy applications perform better, keeping users active and productive.

Thousands of customers currently run mission-critical environments on racks full of aging 1U or 2U dual-processor

servers and back-level Presentation Server software. IBM BladeCenter

products, combined with Citrix Presentation

Manager v4.5, offer an innovative way to update your environment to the latest technology and help achieve the following:

• Vastly reduced server count—reduce your number of servers by up to two-thirds

• Reduce software licensing costs

• Move to 64-bit technology with Presentation Manager v4.5—at no extra cost from Citrix

• Optimize the heat, power, and space requirements of a Presentation Manager farm

• Reduced management overhead vs. running hundreds of servers

Which method is right for you—scale up or scale out? PS v4.5 supports both scale-up (via the IBM System x3800 or

x3850), and scale-out (via BladeCenter blades).

Citrix PS v4.5 offers both 32-bit and 64-bit versions, to support whatever your operating environment is. This provides you

with the flexibility to run a mixed environment initially and migrate over time.

If you have large scale-out “farms” of Citrix PS servers, made up of 1U and 2U servers, you know what a massive

infrastructure and management headache it can be. The BladeCenter family may be the answer if you’re looking to

simplify your infrastructure, improve flexibility and speed of deployment, and consolidate your space, heat, and power use.

BladeCenter chassis support a wide variety of 2- and 4-socket server blades. This flexibility is what makes the platform

ideal for a customer in a state of transition. If you plan to move to PS x64 in 6-12 months, you might prefer an HS21,

HS21 XM, or LS21 blade, running in 32-bit mode initially, and then migrate to an x64 environment later (running the same

hardware). If you have a mixed PS x32/x64 environment, you might choose LS21 or an LS41 2-socket configuration for

your x64 platform, and then later upgrade the LS41 to a 4-socket blade. For a scale-up configuration in a blade form

factor, you might choose a 4-socket/dual-core LS41 or a 2-socket/quad-core HS21 XM right from the start.

The BladeCenter family of products offers you ultimate flexibility and maximum potential investment protection. In addition

to the flexibility of processor choice, there are also huge potential infrastructure consolidation benefits to be had: all

networking, SAN, KVM connectivity, systems management, and power connectivity is integrated into the chassis,

potentially saving large sums of money by requiring fewer cables, PDUs, KVM switches, and other infrastructure

hardware. Additionally, BladeCenter chassis and blade servers offer significantly more efficient heat/power characteristics

than do dozens of 1U and 2U rack servers.
