Executive Overview
The world economy has pulled out of its worst recession since World War II and will stage a
sluggish recovery in the coming years. Because recovery was largely due to massive public
spending by governments, sentiment among small and medium business owners remains barely
improved over that of a year ago. Cash positions have improved, but doubts over the
sustainability of the recovery continue to linger. Yet a more robust turnaround is still somewhere
off in the future. Small and midsized companies are continuing to defer hiring, as business
owners are not yet confident enough about the economy to add employees.
Recent economic conditions have changed the way that businesses operate. At the same time,
the world is becoming smarter—more instrumented, interconnected, and intelligent. Midsized
businesses have to manage increasingly large data pools and a customer base with higher
expectations, without spending more on IT. IBM delivers leading technology solutions—smarter
systems built for a smarter planet, which provide leadership quality, service and value to such
businesses.
In business, growth is good. Having technology and infrastructure capable of keeping up with
growth is even better. Finding the right servers to meet your needs both today and tomorrow can
be the key to sustaining that growth. More than simply equipment, servers are the foundation of a
dependable IT infrastructure.

IBM has announced a new generation of x86 servers—System x and BladeCenter systems and
other supporting options—offering an unbeatable combination of performance, value, storage,
and energy efficiency designed to help you improve service, reduce costs and manage risk. The
new servers include:
• System x3650 M3, x3630 M3, x3620 M3, x3550 M3, and x3250 M3 rack servers
• System x3500 M3, x3400 M3, and x3200 M3 tower servers
• BladeCenter HS22 and HS22V blade servers
® ®
These new servers feature the Intel Xeon Processor 5600 Series, the next generation of
intelligent server processors. With these new servers you gain the benefits of proven reliability,
breakthrough performance and the operational advantages of using advanced server technology
developed specifically for small and medium businesses.
This paper shows how these new x86 servers, by integrating advanced technologies like IBM
Systems Director Active Energy Manager™ and the IBM Integrated Management Module (IMM),
offer an outstanding platform for virtualization and consolidation. Moreover, it’s a platform that’s
easy to use and manage, allowing you to lower total cost of ownership, reduce development
costs, increase performance within the same energy and cooling envelope and with continued
investment protection, and dramatically increase workload performance.
Server Refresh: A Smart Choice
Your servers have done the job so far, but you’re seeing the strains of outdated technology,
having to manage multiple systems and locations, and the growing footprint of piecemeal server
management. Updated servers can also enhance the performance of new applications or
operating systems. You need to make the right choices with your limited IT budget. With IBM
servers based on the latest Intel Xeon processors, your business will have the headroom to
handle bigger data loads and more people, while delivering the performance that your customers
and business demand. And you can do so with fewer servers, not more.
Updating your servers can offer you:

• Optimal support for the latest applications
• New hardware with warranty support
• The ability to consolidate servers through virtualization, to save space, run quieter, and
simplify management
• Reduced total cost of ownership due to lower maintenance costs, more efficient energy
usage, fewer software licenses, and less downtime
Dramatically Reduce Costs
A longtime leader in the data center market, IBM uses a comprehensive understanding of
customers’ evolving computing needs to continually produce new, standards-setting offerings
across an array of product classes. Among the company’s leading-edge products are the System
x3650 M3 and System x3550 M3 rack servers. Featuring innovative and energy-efficient designs,
simplified IT management, and dramatic improvements in performance and function, the x3650
M3 and x3550 M3 set new cost-efficiency standards for the x86 processor-based server market.
As IT professionals evaluate options for x86 server upgrades and additions, Technology Business
Research (TBR), an independent information and market research firm, found that efficiency and
an ability to reduce costs over the life of the server are key criteria in decision making in addition
to reliability, product availability and management capabilities. Users are increasingly focused on
how new infrastructure can help lower costs and improve operations versus the pure horsepower
that a server offers. To that end, IBM focused its development on key feature areas that enable
customers to lower costs or drive more utilization, ultimately painting a picture of high ROI. IBM’s
System x lineup offers further benefits as the machines are part of IBM’s fabric of solutions, which
include IBM software, IBM System Storage®, IBM Global Financing, and IBM Global Services.
This allows customers to maximize their returns by tailoring their broader IT infrastructures,
including their System x servers and adjunct devices, software and services, to solving their
specific business needs.
Additionally, an IBM engineering research study showed that IBM’s new rack servers can reduce
annual energy costs by more than $100 per year per server over previous x3550 and x3650
models through innovative, energy-smart designs and simplified management. Integrating two
Xeon 5600 series processors with Intel QuickPath Technology and Intel Turbo Boost Technology,
the IBM servers deliver dramatic performance improvements over previous generations, while
also offering low acquisition cost. Dramatic performance gains and new virtualization solutions
can offset the initial outlay in fewer than 3 months1.
Designed to be growth engines for expanding businesses, the x3500 M3 and x3400 M3 tower
servers are dual-socket servers equipped with Xeon Processor 5600 series processors. These
are designed to offer high reliability as well as extraordinary performance and outstanding power
efficiency to help reduce costs. Figure 1 shows the x3650 M3, which makes possible the dramatic
server consolidation by replacing 5-year-old rack and tower servers with the new System x
servers. (The x3400 M3, x3500 M3, and x3550 M3 servers offer the same kind of consolidation
potential as the x3650.)

In addition to the energy savings enabled by the more efficient processors, the new IBM servers
also support 1.5V DDR3 memory, which is 15% more energy-efficient than the older DDR2
memory (and even more so than fully-buffered memory), as well as 1.35V DDR3 memory, which
is 19% more efficient than even 1.5V DDR3 memory. With servers now containing as much as
288GB of RAM, this energy savings is significant. Also, the servers incorporate more efficient
power supplies (up to 93% efficiency), transistors, and voltage regulator modules (up to 88%) that
help reduce energy costs, along with 2.5-inch HDDs that use up to 80% less energy than 3.5-inch
drives, and solid-state drives (SSDs) that consume only 2W of power. In addition, integrated
BladeCenter 10Gb Ethernet switches can be more than 95% more energy efficient than external
2
switch offerings . Finally, IBM Systems Director Active Energy Manager provides you with the
tools necessary to monitor actual energy usage (not simply the theoretical maximum power
draw), track trends, and even cap energy usage at a predetermined point.
From a management standpoint, to use features beyond that of the standard Baseboard
Management Controller (BMC) in the older servers, you had to spend several hundred dollars to
purchase an IBM Remote Supervisor Adapter II. Now, that functionality (such as remote
management and IPMI 2.0) is incorporated inside the new IBM Integrated Management Module
3
(IMM), standard in the new servers .
Dramatically Increase Workload Performance
Get great performance, energy and cost-efficiency, and plenty of room to grow and virtualize in
the future with the next generation of IBM x86 servers based on the Xeon 5600 series
processors. These servers offer you maximum performance for heavy workloads, while reducing
energy consumption when workloads are light. It all adds up to intelligent performance that keeps
energy costs low.
Application performance is critical for day-to-day business operations, as well as for creating new
products and services, increasing competitiveness, and reaching new customers. For the past

The x3200 M3, x3250 M3, x3400 M3, x3550 M3, and x3650 M3 require an optional Virtual Media Key (VMK) to enable the remote
presence features of the IMM. The VMK is standard in the x3500 M3. The HS22 and HM22V do not require a VMK for remote
presence.

decade, IT has rapidly added low-cost hardware to accommodate business growth, and many
data centers are now stretched to capacity in terms of power, cooling, and floor space. By
refreshing your data center infrastructure with higher performance, more adaptive, power-
conscious servers, you can deliver additional capability and scalability within the same energy
and space footprint, staying ahead of ever-increasing business demands.
The Xeon 5600 series processors bring together a number of innovative technologies to deliver
intelligent performance. New features include:
• Intel Turbo Boost Technology4 — Turbo Boost dynamically turns off unused processor
cores and increases the clock speed of the cores in use, by up to two model frequencies. For
example, with three cores active, a 3.33GHz 6-core X5680 processor with 3-6 cores active
can run the cores at 3.46GHz. With only one or two cores active, the same processor can run
those cores at 3.6GHz. Similarly, a 3.46GHz 4-core X5677 processor can run at 3.6GHz or
even 3.73GHz. When the cores are needed again, they are dynamically turned back on and
the processor frequency is adjusted accordingly.
• Intel Hyper-Threading Technology (Intel HT) — HT lets today’s well-threaded applications
make the most of every clock cycle. Multi-threaded software applications can execute threads
in parallel within each processor core.
• Intel QuickPath Technology — Along with the integrated memory controller, Intel QuickPath
Technology helps speed traffic between processors and I/O controllers for bandwidth-
intensive applications. With the Xeon 5500/5600 series processors, Intel has diverged from
its traditional Symmetric Multiprocessing (SMP) architecture to a Non-Uniform Memory
Access (NUMA) architecture. The Xeon 5600 series processors are connected through a
serial coherency link called Intel QuickPath Interconnect (QPI). QPI is capable of 6.4, 5.6 or
4.8 GT/s (gigatransfers per second), depending on the processor model. This allows the new
servers to deliver as much as 25.6 GB/s—up to 3.5x the bandwidth of previous-generation
servers.
As a result of these and other improvements, the 5600 series processors offer up to 54% more
performance than a same-frequency Xeon 5500 processor, or the same performance with up
to 30% less energy consumption5.
Dramatically Increase Performance with Continued Investment Protection
Rack and tower servers are not the only area to benefit from new-generation technology. The
BladeCenter HS22 and HS22V blade servers also offers great performance, balanced with
flexible configuration options and simple management. All together, this creates an efficient
server designed to run a broad range of workloads exceptionally well.
You can also mix-and-match the HS22/HS22V with other BladeCenter blades and various
operating systems in existing chassis, including the BladeCenter S and BladeCenter H, for
unmatched investment protection, incredible flexibility and deployment choice. And with features
like Unified Extensible Firmware Interface (UEFI), the IBM Integrated Management Module
(IMM), and IBM Systems Director you can further simplify systems management and future-proof
your infrastructure. Compared to earlier-generation Xeon processor-based servers, HS22/HS22V
blade servers can help improve the economics of your data center with:

BladeCenter H chassis provides equal or greater performance than 310 x346 2U rack servers inside 14.76 rack enclosures, for a
savings of 14.55 racks or 98.5%. In terms of floor space that would save approximately 117 sq. ft. (613U). (Realistically, in most
data centers 2U rack servers cannot be populated that densely, due to air flow and power issues. So the IT footprint savings would
be even greater for BladeCenter H.)

• Up to 96% reduction in energy costs from server consolidation7
• Up to 23X faster performance than 2005-era servers8
In addition, BladeCenter consolidation and integration offers significant benefits over rack
servers:

• Up to 28% lower connectivity costs
10
• Up to 92% fewer cables
You can use the new performance capability to expand your existing IT infrastructure by reusing
your existing chassis.
Dramatically Increase Performance within the Same Energy Envelope
Midsized companies can now enjoy the dramatic increase in performance with new HS22 blades
without increasing their data center space or energy footprint. Figure 3 illustrates how you can
expand your IT infrastructure without bearing the burden of an increase in power cost. (This
example shows new low-voltage 60W HS22 blades used in a 2005-era BladeCenter E chassis

Using a 22.1-to-1 performance ratio of today’s HS22/HS22V to a 2005 xSeries 346 2U rack server, 1 BladeCenter H chassis
containing 14 HS22V blades would provide the computing performance of approximately 310 2U rack servers. 1 BladeCenter H
chassis containing 14 HS22V blade servers consumes an average of 4,382W. 310 2U rack servers consume 119,040W. Thus, the
energy savings for replacing 310 x346 2U rack servers with 1 BladeCenter H chassis is 96.3%.
