Mezzanine cards

The M420 provides one PCIe 3.0 mezzanine connector for add-in cards. The M420 is designed to

be PCIe 3.0-compliant to take full advantage of the processor capabilities. Installation of a

mezzanine card requires an M1000e I/O Module (IOM) of the same fabric technology to be installed

in the corresponding fabric slot of the mezzanine card to support data flow through the fabric/slot.

Table 13 lists the supported mezzanine cards for the M420.

Interconnectivity matrix

The full-height, single-wide M420 sleeve holds up to four M420 blades in four slots: a, b, c, and d.

A maximum of eight sleeves fit into a single M1000e chassis. Understanding how the blades connect

demonstrates the impact of switch choice on the number of available ports, as shown in Figure 6.

Blades connect to Fabrics B and C differently depending on the slot within the M420 sleeve.
