Greetings!!

FlexibleLOM (LAN on motherboard) and mezzanine card for Blade are cards with different types of interfaces (connectors) and they are connected to the system board. Blades servers do not have PCIe slots or there is no option to install PCIe cards vertically, instead they have Mezzanine slot to install add-on cards (having Mezannine connector) horizontally due to space constraint.

If we take "HP ProLiant BL460c Gen8 Server Blade" as an exapmple it supports both HP FlexFabric 20Gb 2-port 630 FLB FlexibleLOM and HP FlexFabric 20Gb 2-port 630M Adapter which is a mezzanine.

So the above 2 network cards are of the same model (HP FlexFabric 20Gb 2-port 630) but with different connector types.
