1. Introduction
This technical product specification (TPS) provides a high-level overview of the features, functions,
architecture, and support specifications of the Intel® Server Board M50CYP2SB family.
The Intel® Server Board M50CYP2SB family contains two server boards: M50CYP2SBSTD and
M50CYP2SB1U. The boards are monolithic printed circuit board assemblies with features that are intended
for high density rack mount server systems. These server boards are designed to support the 3rd Gen Intel®
Xeon® Scalable processor family. Previous generation Intel® Xeon® processor and Intel® Xeon® Scalable
processor families are not supported.
The Intel® Server Board M50CYP2SB family is a foundational building block of the server system. The family
is backed by Intel design excellence, manufacturing expertise, and world-class support to deliver processing
power with high levels of flexibility, manageability, and reliability.
Note: In this document, the 3rd Gen Intel® Xeon® Scalable processor family may be referred to simply as
“processor”.
Note: For more in-depth technical information, see the related documents in Section 1.1.Some of the
documents listed in the section are classified as “Intel Confidential”. These documents are made available
under a Non-Disclosure Agreement (NDA) with Intel and must be ordered through your local Intel
representative.
