2 System features

Compared to the previous generation of Dell PowerEdge blade servers, the M420 has similar
memory scalability, as well as more processor cores in a much denser form factor than ever before.
Features include DDR3 memory, PCIe 3.0, dual internal SD module and Dell's next-generation
iDRAC solution known as iDRAC7 Enterprise with Lifecycle Controller.

Comparison of PowerEdge systems

The PowerEdge M420 is a 2-socket, quarter-height blade server that delivers an extraordinary
balance of value and performance for mainstream business applications, with no compromise on
enterprise-class features.

Designed for exceptionally dense computational environments where space is at an absolute
premium. Best fit for space and/or power conscious, highly available, ultra-dense nodes.

Housed within the PowerEdge M1000e chassis with up to 32 independent, individually
serviceable, M420 blade servers, offering a unique combination of performance, density and
efficiency.

Compared with half-height blades:
Double the density
—
Half the infrastructure costs (chassis and switches)
—
Reduced cabling to top-of-rack (ToR) switches
—
All with no enterprise feature trade-offs
