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:
• 130W 8-core Xeon processor model X7560 at 2.26GHz, with 64-bit extensions, low power draw per
core (16.25W), 6.4 GTps (gigatransfers per second) QPI speed, 978MHz memory access, dual
integrated memory controllers, 24MB of shared L3 cache, and Intel Turbo Boost and Hyper-
Threading technology; supported in BladeCenter H, HT, and S chassis
• 130W 8-core Xeon processor model X6550* at 2.0GHz, with 64-bit extensions, low power draw per
core (16.25W), 6.4 GTps QPI speed, 978MHz memory access, dual integrated memory controllers,
18MB of shared L3 cache, and Intel Turbo Boost and Hyper-Threading technology; supported in
BladeCenter H, HT, and S chassis
• 95W 8-core Xeon processor model L7555 at 1.86GHz, with 64-bit extensions, extremely low power
draw per core (11.9W), 5.86 GTps QPI speed, 978MHz memory access, dual integrated memory
controllers, 24MB of shared L3 cache, and Intel Turbo Boost and Hyper-Threading technology;
supported in BladeCenter H, HT, and S chassis
• 105W 6-core Xeon processor model E7540 at 2.0GHz, with 64-bit extensions, low power draw per
core (17.5W), 6.4 GTps QPI speed, 978MHz memory access, dual integrated memory controllers,
18MB of shared L3 cache, and Intel Turbo Boost and Hyper-Threading technology; supported in
BladeCenter H, HT, and S chassis
• 105W 6-core Xeon processor model E7530* at 1.86GHz, with 64-bit extensions, low power draw per
core (17.5W), 5.86 GTps QPI speed,978MHz memory access, dual integrated memory controllers,
12MB of shared L3 cache, and Intel Turbo Boost and Hyper-Threading technology; supported in
BladeCenter H, HT, and S chassis
• 95W 4-core Xeon processor model E7520* at 1.86GHz, with 64-bit extensions, reduced power draw
per core (23.75W), 4.8 GTps QPI speed, 800MHz memory access, dual integrated memory
controllers, 18MB of shared L3 cache, and Intel Hyper-Threading technology; supported in
BladeCenter H, HT, and S chassis
• 105W 6-core Xeon processor model E6540* at 2.0GHz, with 64-bit extensions, low power draw per
core (17.7W), 5.86 GTps QPI speed, 1066MHz memory access, dual integrated memory controllers,
18MB of shared L3 cache, and Intel Turbo Boost and Hyper-Threading technology; supported in
BladeCenter H, HT, and S chassis
• 105W 4-core Xeon processor model E6510* at 1.73GHz, with 64-bit extensions, reduced power
draw per core (26.25W), 4.8 GTps QPI speed, 800MHz memory access, dual integrated memory
controllers, 12MB of shared L3 cache (available via CTO) , and Intel Hyper-Threading technology;
supported in BladeCenter H, HT, and S chassis
* 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.
