6 PowerEdge R820 Technical Guide
Detailed descriptions
This new family of Intel processors has embedded PCIe lanes for improved I/O
performance. See the Processor section for details.
The Intel Platform Controller Hub (PCH) chip is implemented on the R820 server.
Certain models of E5-4600 series processors support 1600 MT/s memory. The
R820 supports four DIMMs per channel at 1600 MT/s with these processors. See
the Memory section for details.
This new memory option, load-reduced DIMM (LRDIMM), is designed with a buffer
chip (or chips) to replace the register to help minimize loading. LRDIMMs can
increase overall server system memory capacity and speed. See the Memory
section for details.
The Dell Select Network Adapter options allow you to customize your LAN port
combinations from your choice of controller vendors. See the Networking and
PCIe section for details.
The R820 supports the new PERC controller cards with improved functionality and
faster performance. See the Storage section for details.
This new software RAID solution supports RAID 0, 1, 5 and 10; supports maximum
of four hot-plug SATA hard drives or SATA solid-state drives. See the Storage
section for details.
Dell Express Flash PCIe solid-state drives provide fast performance without
requiring processor resources or capturing DRAM. The R820 supports up to four
Express Flash drives. See the Storage section for details.
The new embedded system management solution for Dell servers features
hardware and firmware inventory and alerting, in-depth memory alerting, faster
performance, a dedicated gigabit port, and many more features. See the Dell
OpenManage systems management section for details.
The R820 supports internal graphics processing units (GPUs) for extreme
computing power to solve HPC needs. See the Processor section for details.
A new 1100W DC power supply option is available for the R820. See the Power,
thermal, and acoustics section for details.
The R820 supports advanced power monitoring and power capping tools that can
help manage power consumption. See the Power, thermal, and acoustics section
for details.
Dell has tested and validated an integrated data center solution that enables you
to operate at higher temperatures or even chiller-less. See the Power, thermal, and
acoustics section for details.
The internal dual SD module is a modular fail-safe design that is dedicated for an
embedded ESX hypervisor or other embedded operating system. See the
Supported virtualization for details.
