Dell I/O Modules are used as pairs, with two modules servicing each server module fabric providing a fully redundant solution. I/O Modules may be passthroughs or switches. Passthrough modules provide direct 1:1 connectivity from each LOM/mezzanine card port on each server module to the external network. Switches provide an efficient way to consolidate links from the LOM or Mezzanine cards on the server modules to uplinks into the customer's network. Figure 35. Difference Between Passthroughs and Switch Modules For more information on the I/O module options, see the PowerEdge M-Series Blades I/O Guide. 9.3 Supported Mezzanine Cards and Switches Dell supports one mezzanine design standard and one I/O Module design standard for true modular computing.
