Key Features
Multicore Intel Xeon Processors
The HX5 ships with
1
or
2
high-performance Intel
Xeon 7500
or
6500 Series
processors per
blade. By connecting
2
blades together, the HX5 servers also go a step further by allowing you
to increase the number of sockets from
2
to as many as
4
. The choice of processors includes:

This processor is limited to single-chassis configurations.
Note:
Because of the integrated memory controllers the former front-side bus (FSB) no longer
exists.
With the Xeon 7500 series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
Xeon 7500 processors are connected through three serial coherency links called QuickPath
Interconnect (QPI). QPI is capable of up to
6.4GTps
(gigatransfers per second), depending on
the processor model.
The
4-core Xeon
processors contain
4 complete processor cores
and
8 threads
. Each
processor contains one L3 cache, shared by all the cores. The cores appear to software as
separate physical processors. Four-core processors can offer more than double the performance
of a same-speed 2-core Xeon processor (depending on workload). Similarly,
8-core
Xeon
processors contain
8
processor cores and
16
threads. They can offer more than double the
performance of four-core Xeon processors (again, depending on workload). Likewise, the
six-
core
processors contain
six
processor cores.
Each processor includes two integrated memory controllers, to reduce memory bottlenecks and
improve performance.
Intelligent Power Capability
powers individual processor elements on and off as needed, to
reduce power draw.
Intel’s
Virtualization Technology
(VT) integrates hardware-level virtualization hooks that allow
operating system vendors to better utilize the hardware for virtualization workloads.
