Disclaimer
Intel Corporation server baseboards contain a number of high-density VLSI and power delivery
components that need adequate airflow to cool. Intel’s own chassis are designed and tested to
meet the intended thermal requirements of these components when the fully integrated system
is used together. It is the responsibility of the system integrator that chooses not to use Intel
developed server building blocks to consult vendor datasheets and operating parameters to
determine the amount of airflow required for their specific application and environmental
conditions. Intel Corporation cannot be held responsible if components fail or the server board
does not operate correctly when used outside any of its published operating or non-operating
limits.
7.4 Board Level Calculated MTBF Data
The predicted board Mean Time Between Failures is 102,000 hours of operation. As of this
writing actual MTBF testing across multiple systems is complete with a demonstrated 32,656
hours. Since our current validation test is only run up to about 32,000 hours across multiple
servers, we still maintain that actual MTBF data will likely be over 102,000 hours of operation
based on statistical regression.
7.4.1
Intel SpeedStep® Technology
Intel® Xeon™ processors support the “Geyserville3” (GV3) feature of Intel SpeedStep®
Technology. This feature changes the processor operating ratio and voltage similar to the
Thermal Monitor 2 (TM2) feature. The E7520 platforms support GV3 feature in conjunction with
TM2 feature.
7.4.2
Intel® Extended Memory 64 Technology
The system BIOS on the SE7520BD2 server board supports the Intel Extended Memory 64
capability of the Intel® Xeon™ Processors. This capability does not need to be activated or de-
activated in BIOS Setup. The system will be in IA-32 compatibility mode when booting an OS.
However, such operating systems like Red Hat 3.0 and SuSE 9.1 require a different kernel to
access EMT64 capabilities.
