Dell PowerEdge FM120X4 Server Block for the FX2 - System Overview


When paired with the FX2 converged infrastructure platform with no PCIe slots, the FM120X4 is an excellent choice for large-scale static web hosting, light-weight analytics processing, and other common business applications. The PowerEdge FX2 is a hybrid computing platform with the density of a blade server in a 2U space that supports cooling, power, and networking.


poweredge FM120x4 server block front with 4 x 2.5-inch drive bays The FM120X4 supports four C2000 Atom processors in each module featuring 2, 4, or 8-cores. The FX2 chassis will support up to four FM120x4 half-width chassis. When paired with the FX2 it offers a lower-cost alternative to using the other compatible compute modules. With four of FM120x4 compute sleds installed on the FX2 chassis, that's 16 micro-servers in a 2U chassis.


Each PowerEdge FM120x4 microserver chassis supports four Atom processors. Each Atom processor supports two DIMM modules for up to eight modules in each chassis, and up to 32 modules total with four of these sleds installed in the FX2 chassis. Only 4GB or 8GB DDR3 UDIMM memory modules are supported, again offering cost benefits over DDR4 RDIMMs and LRDIMMs. Memory modules must support the same capacity for each node and there should be at least one memory module installed per node.


Each Dell FM120X4 server supports either four warm-swap 2.5-inch SATA HDs/SSDs but you can also install up to eight hot-swap 1.8-inch uSATA SSDs. Depending on the configuration each Atom processor will have access to either one or two of the supported drives. Only software RAID is supported, and the FM120X4 is not compatible with the FD332 storage sled, which provides a direct attached storage (DAS) solution for the other compute modules supported on the FX2 chassis.

The FM120X4 does not have any PCIe lanes and instead uses one of two different pass-through modules for network communications. The other compute modules are typically configured with two of three different Aggregator modules which are installed directly below the Chassis Management Controller (CMC) module. The CMC module allows up to 20 FX2 systems to be daisy-chained together. The supported pass-through modules feature either a 1GB option with 8 x RJ45 ports or a 10GB option with 16 x RJ45 ports.


As with all Dell PowerEdge systems, the OpenManage portfolio and iDRAC8 with Lifecycle controller are included. The Chassis Management Controller (CMC) also enables Administrators to manage the system independently or collectively using a browser. Express and Enterprise licensing is available for more functionality depending on your business needs.


The converged PowerEdge FX2-series offers a modular, scalable infrastructure to accommodate a wide range of common and mission-critical business applications. The PowerEdge FM120x4 compute node offers an affordable option for system administrators. Featuring flexible virtualization and impressive VM density, the Dell FM120x4 can easily support your business needs in a very compact space. With Dell's powerful management tools, it's easy to manage the system on site or remotely.

FX2 Shared Infrastructure Platform

poweredge FX2 chassis front perspective

Dell's PowerEdge FX2 is a 2U converged infrastructure platform that offers the easy deployment of a rack server with the performance of a mini blade enclosure in a 2u rack space. There are two FX2 chassis. One with no PCIe slots, the FX2, and another which supports eight PCIe slots, the FX2s. Both are compatible with the PowerEdge FC430, PowerEdge FC630, PowerEdge FC830, and the FD332 storage block. However, the PowerEdge FM120x4 is designed specifically for the FX2 with no PCIe slots and cannot be used with the FD332 storage block.

FX-Series Compute and Storage Modules

FC430 Compute Module

poweredge fc430 front perspective

The FC430 is a quarter-width compute module that can support two Xeon E5-2600 v4 processors or a single E5-1600 v3 processor. Up to eight FC430 compute modules can be installed in the FX2 chassis for a maximum of 2TB of memory. The FC430 can also be used with the other compute modules or the FD332 storage sled supporting 16 additional drives. Two 1.8-inch bays up front supports either two 1.8-inch uSATA drives or an optional low-latency configuration that combines a 1.8-inch drive with two QSFP+ compact, hot-pluggable transceiver connectors for Ethernet or Infiniband connectivity. Each sled has access to one PCIe 3.0 slot on the FX2s chassis. With an optimal balance of memory and storage, this module is perfect for high-speed I/O for mainstream enterprise workloads, including mid-sized virtualization and database environments. The low-latency Infiniband configuration is ideal for High Frequency Trading and High Performance Computing.

The Dell PowerEdge FC630 is a half-width, two-socket compute module that can support a maximum of two Xeon E5-2600 v3 or E5-2600 v4 processors. Up to four FC630s can be installed in the FX2s chassis and each automatically connects maps to two of the eight PCIe modules. The FC630 can also be used in conjunction with other compute modules or the PowerEdge FD332 storage module for dense direct attached storage. The FC630 has 24 DIMM slots that can provide up to 1.5TB of memory. With four FC630 sleds installed in the FX2s enclosure, a maximum of 6TB of memory is available. Up front there's room for two 2.5-inch drives or another FC630 chassis that supports up to eight 1.8-inch SSDs. This unit is deal for large databases or highly virtualized environments.
