performing, more efficient processors can accelerate data center
ROI, saving on power and cooling, space, labor, and software licensing costs. By refreshing IT infrastructure with more energy-efficient
systems, you gain capacity to grow and to increase IT performance,
reduce energy costs by 95 percent, and realize ROI in 5 months.2
With up to 15x the performance compared to installed single-core
servers2 and unique virtualization capabilities, Intel Xeon processor
5600 series lets you deliver more business results from every clock
cycle, every IT man-hour, every watt, and every inch of data center
space. The lower TCO and groundbreaking performance of the Intel
Xeon processor 5600 series offers the opportunity to transform
the competitiveness of your business and the economics of your
data center.
Performance That Adapts
to Your Software Environment
Application performance is critical for day-to-day business operations,
as well as creating new products and reaching new customers. But
many data centers are now at capacity, and new data centers are
expensive to build. By refreshing data center infrastructure with more
efficient servers, you can deliver additional performance and scalability
within the same energy and space footprint.
The Intel Xeon processor 5600 series brings intelligent performance
to the most widely deployed server architecture. The Intel Xeon
processor 5600 series is the world’s most adaptable server platform,
adjusting performance and power usage in real time to meet the exact
requirements of your computing workloads, while allowing manual
adjustment for IT control.
Automating Energy Efficiency
The Intel Xeon processor 5600 series brings together a number of
innovative technologies to deliver intelligent performance:
• Intel® Turbo Boost Technology, together with Intel Intelligent
Power Technology, delivers performance on demand, letting processors operate above the rated frequency to speed specific workloads
and reduce power consumption during low utilization periods.
§
• Intel® Hyper-Threading Technologyф benefits from larger caches
and massive memory bandwidth, delivering greater throughput
and responsiveness for multi-threaded applications.
• Intel® QuickPath Technology and an integrated memory controller
speed traffic between processors and I/O controllers for bandwidthintensive applications, delivering up to 4.4x the bandwidth for
technical computing.4
The intelligent performance of the Intel Xeon processor 5600 series
also gives IT fine-grained manual control to adapt to changing priorities
or to meet service-level agreements (SLAs). For example, Intel Intelligent
Power Technology enables policy-based control that allows processors
to operate at optimal frequency and power. The operating systems can
make this determination automatically, or administrators can designate
which applications require high-frequency processing and which should
be executed at lower frequencies to conserve power.
After decades of IT build-out, server sprawl is escalating system
management costs and outstripping available data center space,
power and cooling capabilities. In a recent survey, 42 percent of data
center owners said they would exceed power capacity within the next
12-24 months, and 39 percent said they would exceed cooling capacity
in the same timeframe.5 Energy efficiency is becoming a critical issue in
the data center.
Intel Xeon processor 5600 series automatically regulates power
consumption to combine industry-leading energy efficiency with
intelligent performance that adapts to your workload. With capabilities
such as new lower power SKUs and low-voltage memory options that
can save up to 10 percent in memory power,6 you can achieve up to
40 percent better performance in a similar power envelope.3 And the
wide range of CPU, power, and memory options allows you to align
your performance and energy requirements without having to make
a trade-off in either.
In addition, Intel Intelligent Power Technology makes power available
for critical workloads while conserving power when there is less demand.
Intel Turbo Boost Technology is also available, which allows processors
to deliver higher speed execution on demand by using available power
to run at a higher frequency, Intel Xeon processor 5600 series gives
you the intelligent performance and flexibility you need to build the
data center of the future today.

Maximizing Benefits from Virtualization
Secure, flexible virtualization
Intel Xeon processor 5600 series can also help tame server sprawl
by providing up to 15:1 consolidation capacity.2 Built on Intel Microarchitecture Nehalem, the Intel Xeon processor 5600 series expands
the benefits of virtualization beyond consolidation with innovations
that can help boost performance, increase consolidation ratios, and
enable servers of different generations to be combined in the same
virtualized server pool, improving virtual machine failover, load balancing,
and disaster recovery capabilities. With more performance in the same
power envelope, you can use virtualization to deliver high-availability
solutions with the agility to address disaster recovery and real-time
workload balancing so your business can respond to the expected
and the unexpected.
As enterprises become borderless, security attacks rise – from DoS
to phising to malware to data leakage. This keeps security challenges
foremost in the minds of IT staff. And with the mixed environment in
most data centers, servers are anything but secure. Intel Xeon processor 5600 series has two new security features that help you secure
your data by speeding up data encryption and protecting against
software attacks at launch.
Intel Xeon processor 5600 series with next-generation Intel®
Virtualization Technology∆ (Intel® VT) enhances virtualization
performance by up to 3.5x and reduces roundtrip virtualization
latency by up to 2x.7
Other virtualization features include:
• Intel® Virtualization Technology (Intel® VT-x) continues to offer
investment protection and infrastructure flexibility with multigeneration VM migration across the full range of 32-bit and
64-bit configurations, enabling bigger VM pools.
• Intel® Virtualization Technology for Connectivity (Intel® VT-c)
provides hardware-assisted I/O that accelerates network performance and simplifies VM migration.
• Intel® Virtualization Technology for Directed I/O (Intel® VT-d) helps
speed data movement and eliminates much of the performance
overhead by giving designated VMs their own dedicated I/O devices,
reducing the overhead of the VM migration in managing I/O traffic.
Intel® Microarchitecture Nehalem helps
lower energy costs with automated energyefficiency features that put processor power
and memory into the lowest available states
needed to support current workloads without
compromising performance.

Data encryption is not new, but new AES instructions from Intel
are. In the past, data encryption either required custom hardware,
such as security appliances and HDDs, or took away from CPU
performance to manage. But with Intel® AES (Advanced Encryption
Standard) Technology, you get robust encryption without needing
additional appliances or increased performance overhead. In fact,
AES-NI improves CPU performance for encryption by as much as a
52 percent for secure Internet transactions,8 and allows for broader
use of encryption throughout the data center.
Intel® Trusted Execution Technology† (Intel® TXT) addresses a critical
security need for all server deployments, especially virtualized and
cloud-based use models by helping protect your server prior to OS
launch or hypervisior launch. Intel TXT complements other malware
protections such as anti-virus and intrusion detection to help ensure
that only trusted software is on the platform. VMs on trusted platforms
are also protected, so you can easily migrate them onto other trusted
platforms or create pools of platforms with trusted hypervisors.
Intel Xeon processor 5600 series helps future proof your data center
with improved security features for evolving usage models.
Exploring Intel® Microarchitecture Nehalem
The new generation of server processors from Intel provides a foundation for a fully adaptable IT environment.
The architecture of these processors is designed with innovative features that adapt performance to software
and business needs, help energy consumption for optimum performance and efficiency, and enable virtualization
strategies that help your IT infrastructure adapt more quickly to your business needs.
Intel® Turbo Boost Technology
Intel® QuickPath Technology
Intel Turbo Boost technology delivers performance when and where
it’s needed (see Figure 1). This technology allows processors to
deliver higher speed execution on demand by using available
power to run at a higher frequency.
To deliver top performance for bandwidth-intensive applications, the
Intel Xeon processor 5600 series features Intel QuickPath Technology
(see Figure 2). This new scalable, shared memory architecture delivers
memory bandwidth leadership, and up to 4.4x the bandwidth of
previous-generation processors.4
Intel® Hyper-Threading Technology
Many server and workstation applications lend themselves to parallel,
multi-threaded execution. Intel Hyper-Threading Technology enables
simultaneous multi-threading within each processor core, up to two
threads per core or eight threads per quad-core processor. Hyperthreading reduces computational latency, making optimal use of
every clock cycle. For example, while one thread is waiting for a
result or event, another thread is executing in that core, to
maximize the work from each clock cycle.
Intel QuickPath Technology is a platform architecture that provides
high-speed (up to 25.6 GB/s), point-to-point connections between
processors, and between processors and the I/O hub. Each processor
has its own dedicated memory that it accesses directly through an
Integrated Memory Controller. In cases where a processor needs to
access the dedicated memory of another processor, it can do so
through a high-speed Intel® QuickPath Interconnect (Intel® QPI)
that links all the processors.
Intel Microarchitecture Nehalem complements the benefits of Intel
QPI by enhancing Intel® Smart Cache with an inclusive shared L3 cache
that boosts performance while reducing traffic to the processor cores.

Intel® Intelligent Power Technology
Within a single server, Intel Intelligent Power Technology minimizes
power consumption when server components are not fully utilized.
• Integrated Power Gates (see Figure 3) allow individual idling
cores to be reduced to near-zero power independent of other operating cores, reducing idle power consumption to 10 watts, versus
16 or 50 watts in prior-generations of Intel processors.9 This feature
reduces server idle power consumption by up to 50 percent versus
the previous generation of two-socket server processors.10
• Automated Low-Power States automatically put processor and
memory into the lowest available power states that will meet the
requirements of the current workload (see Figure 4). Processors are
enhanced with more and lower CPU power states, and the memory
and I/O controllers have new power management features.
Intel® Virtualization Technology
Next-generation Intel Virtualization Technology enhances virtualization performance with new hardware-assist capabilities across all
elements of your server:
• Processor: Improvements to Intel Virtualization Technology (Intel
VT-x) provides hardware-assisted page-table management, allowing
the guest OS more direct access to the hardware and reducing compute-intensive software translation from the VMM. Intel VT-x also
includes Intel VT FlexMigration and Intel VT Flex-Priority, which are
capabilities for flexible workload migration and performance optimization across the full range of 32-bit and 64-bit operating environments.
• Chipset: Intel Virtualization Technology for Directed I/O (Intel VT-d)
helps speed data movement and eliminates much of the performance
overhead by giving designated virtual machines their own dedicated
I/O devices, thus reducing the overhead of the VMM in managing
I/O traffic.
• Network Adapter: Intel Virtualization Technology for Connectivity
(Intel VT-c) further enhances server I/O solutions by integrating extensive hardware assists into the I/O devices that are used to connect
servers to the data center network and storage infrastructure. Two
technologies comprise Intel VT-C: Virtual Machine Device Queues,
which accelerates thoughput and reduces the load on the VMM and
server processors; and PCI-SIG SR-IOV, which delivers near-native
throughput and provides dedicated, direct connectivity between
VMs and hardware resources.11
