What is FlexibleLOM?

System Board with an embedded NIC is referred as LAN-on-motherboard (LOM) architecture.

FlexibleLOM uses a system board edge connector that accepts a FlexibleLOM adapter, which integrates seamlessly.


Benefits of FlexibleLOM over LOM (LAN on Motherboard)?

Mezzanine

In previous generation servers, we had LOM which is integrated onto the system board. If a user desired a different kind of networking adapter, they would need to purchase a PCI adapter and install it in a slot in the server. This was consuming mezzanine or PCI slots which reduced the flexibility to add other mezzanine cards or PCI cards.


What is FLR and FLB?

FlexibleLOM Rack (FLR) adapter for rack mount servers.

FlexibleLOM Blade (FLB) adapter for Blade servers.


What is the PCIe interface used by FlexibleLOM in Rack Servers?

FlexibleLOM technology uses a custom implementation of the PCIe 3.0 x8 interface. FlexibleLOM technology does not require additional CPU resources over standard LOM architecture and does not occupy a regular PCI slot.


What is the interface used by FlexibleLOM in Blade Servers?


FLB uses PCI Express v2.0 (Gen 2) x8 interface. The FlexibleLOM Blade adapter installs as a daughter card on the server blade board, just like a mezzanine card.


How to install FlexibleLOM?

Refer to the respective server’s maintenance guide or FlexibleLOM’s installation guide.
