One or two servers are supported in the 2U chassis depending on the whether a PCIe tray is attached:
Compute-intensive configurations

For the highest compute performance, two servers are installed in one single 2U chassis. Each server
can have:
Two PCIe 3.0 x16 full-height/half-length adapters (a total of four in the 2U chassis)

One 3.5" simple-swap SATA drive, or two 2.5" simple swap SAS/SATA HDDs, or SSDs, or four

1.8" simple-swap SSDs
Figure 2 shows this chassis configuration.
GPU and coprocessor configurations

The PCIe tray (feature code A1UH) attaches to a single dx360 M4 server and forms a 2U server that
installs in the 2U chassis. With two 2U riser cards, the combined unit has the following expansions:
Two double-wide PCIe graphics cards in the upper half of the chassis, slots 3 and 4, each PCIe

3.0 x16 supporting full-height, full-length, double-width PCIe adapters
Two PCIe cards in the lower half of the chassis, slots 1 and 2, each PCIe 3.0 x8 supporting

full-height, half-length PCIe adapters
Two disk bays on the left for either two 3.5-inch disk drives, four 2.5-inch disk drives, or eight

1.8-inch solid-state disks
Figure 5 shows the configuration with the PCIe tray.

Each iDataPlex chassis provides a shared high-efficiency power supply and fans. The iDataPlex uses
Direct Dock Power to power the nodes in the chassis. Industry standard power cords power each node,
but the cords are attached to the rack in a fixed location. When you slide in the chassis, the power
receptacle of the chassis simply connects to the power cord, which means that you do not have to access
the rear of the rack to attach the power cord.
