1.4 System Architecture Overview
The Purley Platform Motherboard contained within the chassis supports and allocates the proper power and
communication throughout the enclosure and components. The motherboard contains physical connections
for dual Skylake CPUs, one platform controller hub (PCH), 24 DIMM sockets, two PCIe slots, eight internal
PCIe slots (three are available for expansion), one system BMC, and one removable Trusted Platform Module
(TPM).
The Ultrastar Serv24 contains two Skylake 2S CPUs that manage and direct the instructions to the necessary
component in the enclosure. The CPUs support 1.0 MB Mid-Level Cache (MLC) and Intel Hyper-Threading
Technology per core. The Ultrastar Serv24 uses a Lewisburg PCH combined with the Skylake Server and
Workstation to provide more bandwidth and flexibility in the I/O. It allows for better management of power
within the enclosure and the enclosure components.
The out-of-band management is controlled through Integrated Remote Management Processor system BMC.
The system BMC provides a VGA port, a COM port, four USB 3.0 ports, and a 1 GbE port using IPMI and
Web UI for BMC management of the enclosure services. The Trusted Platform Module (TPM) provides system
security that communicates with the rest of the system through a device attached to the motherboard. The
TPM is physical security barrier with a pre-operating system environment that allows for more control over
the software’s security protocol. The security within the TPM is based on trust in the communication partner
and the reliability of the connection.
