●
The server supports two Intel
®
Xeon
®
Scalable processors.
●
The server supports up to 24 memory modules.
●
The CPUs (processors) interconnect with each other through three UPI links at
a speed of up to 10.4 GT/s.
●
The mezzanine cards connect to the processors through PCIe buses to provide
service ports.
●
The Platform Controller Hub (PCH) has a built-in MAC chip and provides two
10 Gbit/s ports.
●
The processors, PCIe Switch, and SAS/SATA/NVMe drive backplane constitute
a storage module. The PCIe Switch expands 12 PCIe x4 channels for the
processors, allowing the SAS/SATA/NVMe drive backplane to support 12
NVMe PCIe SSDs.
