System Overview; Introduction; New Technologies - Dell PowerEdge R940 Technical Manual

Introduction

The Dell EMC PowerEdge R940 is a latest 4-socket, 3U monolithic rack server designed to run complex workloads using highly scalable
memory, I/O, and network options. The system features the Intel Xeon Processor Scalable family, with up to 48 DDR4 DIMMs, up to 13 PCI
Express (PCIe) 3.0 enabled expansion slots, and a choice of embedded NIC technologies.
The PowerEdge R940 is a general-purpose platform capable of handling demanding workloads and applications, such as data warehouses,
ecommerce, databases, and high-performance computing (HPC).
The PowerEdge R940 adds extraordinary storage capacity options, making it well-suited for data-intensive applications that require greater
storage, while not sacrificing I/O performance.

The embedded systems management solution for PowerEdge features hardware and firmware
inventory and alerting, in- depth memory alerting, faster performance, a dedicated gigabit port
and many more features. See the OpenManage systems management section for details
The Quick Sync feature is an extension of NFC based low bandwidth Quick sync interface. Quick
Sync 2.0 will offer feature parity with NFC interface with improved user experience. Since the
introduction of iDRAC in PowerEdge Server, the server management has been improved by
adding different local and remote user interfaces (Web GUI, RACADM, WSMAN, BIOS F2 Setup,
and LCD) to iDRAC. The addition of Quick Sync 1.0 (NFC) interface in 13G server with handheld
devices (Mobile, tablet) and OMM Android application. To extend this Quick Sync feature to wide
