allows an administrator to restart a server without having to visit it in person, saving travel time
and getting the server back up and running quickly and securely. It also adds new features to
those provided by IPMI 1.5, including
VLAN support, Serial over LAN, enhanced
authentication and encryption algorithms ( RMCP+ and AES) and a firmware firewall.
• Temperature-controlled fans adjust to compensate for changing thermal characteristics. At
the lower speeds they draw less power and suffer less wear. Equally important in a crowded
data center, temperature-controlled fans produce less ambient noise in the data center than if
they were constantly running at full speed.
• The three-year (parts and labor) limited onsite warranty
5 helps afford you peace of mind
and greater investment protection than a one-year warranty does.
Key Features
High-Performance / High-Efficiency Xeon 5600 / 5500 Processors
The x3620 M3 supports up to two high-performance Intel Xeon 5600 Series or 5500 Series
processors, allowing you to upgrade to a second processor as your business needs require. The
x3620 M3 offers a choice of processor clock rates, memory access speeds and energy draw,
including:
• 95W 6-core Xeon 5600 models X5650 running at 2.66GHz with reduced power draw and
impressive performance/watt (only 15.83W per core; 6.4GTps QPI speed), 12MB of L3
processor cache, 1333MHz memory access, 2 threads per core, and Intel Turbo Boost and
Hyper Threading technology
• 80W 4-core Xeon 5600 models E5620 or E5630 running at 2.4 or 2.53GHz, respectively, with
reduced power draw and impressive performance/watt ( 20W per core; 5.86GTps QPI speed),
12MB of L3 processor cache, 1066MHz memory access, 2 threads per core, and Intel Turbo
Boost and Hyper Threading technology
• 80W 4-core Xeon 5500 models E5506 or E5507 running at 2.13 or 2.26GHz, respectively, with
reduced power draw and impressive performance/watt ( 20W per core; 4.8GTps QPI speed),
4MB of L3 processor cache, and 800MHz memory access
Also available, via configure-to-order (CTO):
• 60W 6-core Xeon 5600 low-voltage model L5640 running at 2.26GHz with low power draw
and impressive performance/watt (only 10W per core; 5.86GTps QPI speed), and 12MB of
shared L3 cache, 1333MHz memory access, 2 threads per core, and Intel Turbo Boost and
Hyper Threading technology (CTO only)
• 40W 4-core Xeon 5600 low-voltage model L5630 running at 2.13GHz, with extremely low
power draw and amazing performance/watt (only 10W per core; 5.86GTps QPI speed), 12MB
of L3 processor cache, 1066MHz memory access, 2 threads per core, and Intel Turbo Boost
technology
With the Xeon 5500 and 5600 Series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
processors are connected through serial coherency links called QuickPath Interconnect (QPI).
QPI is capable of 6.4, 5.6 or 4.8 GTps (gigatransfers per second), depending on the processor
model.
4-core Xeon processors contain four complete processor cores. Each 5600 Series processor
contains one
12MB L3 cache shared by all the cores. The shared cache is dynamically allocated
among the cores as needed. The multiple cores appear to software as multiple physical
processors. Four- and six-core processors offer considerably higher performance than a same-
speed Xeon processor with 2 cores.
Turbo Boost Technology increases performance by translating the temperature, power and
current head room into higher frequency. It will dynamically increase by 133MHz for short and
regular intervals until the upper limit is met or the maximum possible upside for the number of
active cores is reached. The maximum frequency is dependent on the number of active cores.
The amount of time the processor spends in the Turbo Boost Technology state depends on the
workload and operating environment, providing the performance you need, when and where you
need it. For example, a
2.66GHz 6-core X5650 processor with 3-6 cores active can run the cores
at 2.93GHz. With only one or two cores active, the same processor can run those cores at
3.06GHz. Similarly, a 2.4GHz 4-core E5620 processor can run at 2.53GHz or even 2.66GHz.
When the inactive cores are needed again, they are dynamically turned back on and the
processor frequency is adjusted accordingly.
In processors implementing Intel Hyper-Threading Technology, each core has two threads
capable of running an independent process. Thus, a 6-core processor can run 12 threads
