Detailed descriptions
This new family of Intel processors has embedded PCI Express
improved I/O performance and additional new features. See the Processors
section for details.
The Intel Platform Controller Hub (PCH) chip is implemented on the M820.
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 more information.
Dell's Select Network Adapter options allow you choose the right network fabric
without using up a valuable mezzanine card slot. See the Networking and
mezzanine cards section for details.
The M820 supports new Dell PERC controller cards with improved functionality
and faster performance. See the Storage section for details.
Dell Express Flash PCIe solid-state drives (SSDs) provide fast performance without
requiring processor resources or capturing DRAM. The M820 supports up to two
Express Flash PCIe SSDs. 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 Systems
management section for details.
The M820 supports advanced power monitoring and power capping tools that can
help manage power consumption in the data center.
The internal dual SD module enables Dell's unique Failsafe Virtualization
architecture, ensuring uptime by providing failover capability for embedded
hypervisors, such as VMware
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.
