 no - that was referring to the existing EOMA-68 standard, which is a
standard designed for mass-volume appliances, *not* servers.  EOMA-68
just happens to include USB3, 10/100/1000 Ethernet and SATA-III.

 yes.  but in doing so, you now force *all* devices to have *exactly*
those features.  they can NOT be optional.  so if the standard
requires 2x 10/100/1000 Ethernet, then any SoCs which do not have 2x
10/100/1000 Ethernet are automatically excluded.  likewise for any
other features.

 ok, so that's at least a case for having 2-sata and 2-GbE and at
least 2of 1x PCIe.  the ECX-1000 definitely has this level of
functionality.

 does anyone know of any other SoCs which have 2 SATA, 2 GbE and 2of
1x PCIe?  or anything remotely close to that?
