Dell PowerEdge FX2 Modular 2U Chassis - System Overview


The converged architecture of the Dell FX2 means management, power, and cooling of the IT resources are centralized, like a mini blade server. While the FX2s chassis, with an "s", features 8 hot-swap PCIe modules, the FX2 (without the "s") does not have integrated PCIe modules. Compute, storage, and networking are shared in the 2U space and expansion is easily accomplished incrementally by adding more compute nodes or by adding additional FX2 enclosures.

Both chassis support the PowerEdge FC430, PowerEdge FC630, PowerEdge FC640, PowerEdge FC830, and the PowerEdge FD332 storage module. However, the FX2, without the "s" also supports the half-width PowerEdge FM120x4 server node featuring four discrete servers in each node. It should be noted that the PowerEdge FD332 storage module is not compatible with the FM120x4 server node. Dell calls the FM120x4 the world’s first enterprise-class micro-server. An expansion bus provides the connection between the FX2s enclosure, with PCIe slots, and the compute sleds. On the other hand, the FX2 does not support the expansion bus because there are no PCIe module slots on the system board of the FX2.


Dell FX2 front extreme perspective with 8 FC430

The compute modules supported on the Dell FX2 are powered by the latest generation Intel Xeon v3 and v4 processors and support DDR4 memory modules. The exception to this is the FM120x4, which features four Intel Atom C2000 processors, and the FC430, which also supports a single E5-1600 v3 processor.

The Dell FX2 supports these combinations of compute sleds (Note: The FD332, storage sled is not compatible with the FM120X4)

  • Up to four half-width PowerEdge FC630 or PowerEdge FM120x4 compute sleds
  • Up to four half-width PowerEdge FC640 compute sleds
  • Up to eight PowerEdge FC430 compute sleds
  • Up to two PowerEdge FC830 compute sleds
  • Up to four PowerEdge FC430 compute sleds mixed with up to two PowerEdge FC630 compute sleds
  • One PowerEdge FC830 compute sled mixed with up to two PowerEdge FC630 compute sleds


Dell FX2 back of system with no integrated PCIe slots

The FX2 is a lower-cost alternative to the FX2s and does not support any PCIe slots. Two FN I/O modules or aggregators can be installed on the system for network connectivity and up to eight 10GbE ports. These replace the standard network interface, simplifying cable management and optimizing "east/west" server to server traffic within the Dell FX2 and LAN/SAN convergence. There are three different Aggregator modules to choose from. Two, the FN 410S I/O Module and FN 410T I/O Module, support four ports with either copper or fiber optic cables. And the third aggregator module, the FN2210S I/O Module, offers a combination of four 10GbE ports and two fiber channel 2 plus 2 ports of SFP and 10GbE. The chassis management controller (CMC) module located just above the aggregator or pass-through module slots, has two ports, one for management and one for stacking that can also be used for CMC redundancy.


The FX uses the Chassis Management Controller (CMC) to manage nodes and system resources from a web interface. If you are familiar with the CMC on the PowerEdge M1000e or the PowerEdge VRTX shared infrastructure platform, then you should have no problems navigating CMC on the FX2 as the interface is practically identical. Two RJ-45 ports on the back connect to the external management network, the second port allows up to 20 chassis to be daisy-chained together for access to more shared resources. The OpenManage portfolio supports local and remote management for the FXs system. All compute modules supported on the FX2 feature Dell's iDRAC8 with Lifecycle Controller, so you can manage the servers individually without the CMC. However, using the CMC will allow a one-to-many interface to view all supported nodes in the chassis and in other connected chassis. Both iDRAC8 and CMC are available with Express and Enterprise licensing depending on your management needs.


The FX2 server offers powerful performance in a 2U space and is a highly scalable, and flexible platform suitable for a number of different workloads depending on your choice of compute modules and storage. The PowerEdge FX2's modular, blade-like configuration consolidates shared resources and its densely packed 2U form factor go a long way towards reducing operational cost.
