Dell PowerEdge M820 Technical Manual page 10

The Dell PowerEdge M820 implements a new module design that supports up to 48 DIMMS and
four processors. The M820 is a full-height blade server that requires a PowerEdge M1000e chassis
to operate. It occupies one slot vertically in the M1000e for a maximum of 8 blade servers in one
M1000e chassis. The M820 can be mixed with other existing Dell blades of quarter-height, half-
height and full-height form factors.
The following sections provide external and internal views of the system and describe the module
Dell
features. For more detailed information on features and descriptions for the M820, see the
PowerEdge M820 Systems Owner's Manual on Support.Dell.com/Manuals.
As shown in Figure 1, the M820 module supports up to four front-accessible, hot-plug hard drives
and three USB ports.
The chassis design of the M820 is optimized for easy access to components and for airflow for
effective and efficient cooling. Figure 2 shows the M1000e chassis enclosure populated with M820
modules.
