In 2005, a VSO VITA 56 working group was established to specify a new mezzanine card that could replace the aging PCI Mezzanine Card (PMC) in 6U embedded systems. This mezzanine card, also known as Express Mezzanine Card (EMC), will offer embedded systems an expansion option that supports the latest and future multi-Gigabit serial fabrics and provides greater levels of manageability and serviceability. These include the ability to remove the module from its host through the front panel. In the first half of 2007, the base EMC specification (EMC.0) will be released under VSO guidelines for trial use.
