Dell PowerEdge R750 BIOS And UEFI Reference Guide

The Dell EMC PowerEdge R750 is a dual-processor rack server designed by Dell that delivers scalable compute power for mission-critical enterprise workloads. Built on Intel Xeon Scalable processors, this model supports extensive core counts per socket with hyper-threading enabling up to two logical processors per core, while processor interconnect speed can be tuned via Ultra Path Interconnect links to balance performance and power consumption. The memory architecture accommodates high-capacity DDR4 DIMMs with configurable frequency targets, supporting Node Interleaving for symmetric configurations or Non-Uniform Memory Architecture for asymmetric layouts, and includes Adaptive Double DRAM Device Correction to mask failing DRAM modules. Additionally, the Dell EMC PowerEdge R750 supports Intel Persistent Memory technologies, providing storage-class memory options for latency-sensitive applications requiring large data pools.

Storage and expansion configurations in the Dell EMC PowerEdge R750 utilize embedded SATA and NVMe controllers with RAID capabilities accessible through UEFI boot modes. The system board features multiple PCIe slots supporting bifurcation for paddle cards and risers, allowing flexible adapter placement, while BOSS PCIe cards offer internal M.2 drives for dedicated boot media. An Internal Dual SD Module enables mirrored redundancy for operating system images, ensuring data integrity across storage interfaces. Networking integration includes embedded NICs with UEFI PXE and HTTP device support for remote deployment, alongside I/O Acceleration Technology to reduce CPU utilization during high-throughput traffic. The R750 model also incorporates slot disablement controls and Memory Mapped I/O above 4 GB to optimize resource distribution for large graphics accelerator or network interface card installations.

Security implementations in the Dell EMC PowerEdge R750 encompass Trusted Platform Module versions 1.2 and 2.0, UEFI Secure Boot with customizable policy modes, Intel Software Guard Extensions for isolated execution environments, and Intel Total Memory Encryption to protect data at rest. Administrators can enforce access restrictions using system passwords, setup locks, and the integrated Lifecycle Controller for automated firmware updates, while the out-of-band iDRAC interface provides comprehensive remote management and diagnostic tools. Redundant OS Control features allow the Dell EMC PowerEdge R750 to maintain backup operating systems on internal drives or SD media for rapid failover. With configurable Thermal Design Power levels and system profiles ranging from Maximum Performance to Power Per Watt efficiency, this server addresses diverse buyer needs for virtualization hosts, high-performance databases, and environmentally conscious cloud data centers requiring robust reliability and lifecycle management.
