7 PowerEdge M420 Technical Guide
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.
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
