Detailed descriptions
Intel Xeon processor
E5-4600 product family
This new family of Intel processors has embedded PCIe lanes for improved I/O
performance. See the Processor section for details.
Intel C600 series chipset
The R820 server uses the Intel Platform Controller Hub (PCH) chip.
1600MT/s DDR3
memory
Certain models of the Intel Xeon processor E5-4600 product family support
1600MT/s memory. The R820 supports four DIMMs per channel at 1600MT/s with
these processors. See the Memory section for details.
LRDIMM
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.
Flexible LOM
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.
Next-generation PERC
options
The R820 supports the new PERC controller cards with improved functionality and
faster performance. See the Storage section for details.
PERC S110 software
RAID Solution
This new software RAID solution supports RAID 0, 1, 5 and 10; supports maximum
of four hot-plug SATA hard drives or SATA SSDs. See the Storage section for
details.
Express Flash drives
Dell Express Flash PCIe SSDs 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.
iDRAC7 with Lifecycle
Controller
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.
Internal GPU support
The R820 supports internal graphics processing units (GPUs) for extreme
computing power to solve HPC needs. See the Processor section for details.
DC power supply
A new 1100W DC power supply option is available for the R820. See the Power,
thermal and acoustics section for details.
Advanced power
management
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.
Fresh Air cooling
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.
Failsafe hypervisors
The internal dual SD module enables Dell's unique Failsafe Virtualization
architecture, ensuring uptime by providing failover capability for embedded
hypervisors, such as VMware
®
vSphere
®
ESXi™.
