25GBase-X server NIC

The ATTO FFRM-N322-DA0 is a 25GBase-X network interface card built for servers that need 25 gigabit connectivity. It installs into a PCI Express 3.0 x8 slot and uses an SFP28 cage for optical fiber media. This plug-in card targets IT teams upgrading rack-mount or tower servers to higher bandwidth links.

SFP28 cage for optical fiber

The card provides an SFP28 expansion slot that accepts 25G SFP28 transceivers, letting you choose single-mode or multi-mode optics to match your cabling plant. No transceivers are included, so you must source compatible modules separately. The optical interface replaces copper cabling for longer runs between switches and servers.

PCI Express 3.0 x8 host interface

The card requires a free PCI Express 3.0 x8 slot, which delivers the throughput needed for 25GBase-X line rate. Servers limited to x4 or PCIe 2.0 slots cannot supply sufficient bandwidth. Verify the motherboard or riser provides a physical and electrical x8 connection before ordering.

Questions about this item

Will the SFP28 transceivers on the FFRM-N322-DA0 need periodic replacement?

The SFP28 modules are hot-swappable optics; only the transceiver itself is replaced if a link fails or a different fibre type is required.

What limits sustained throughput on this 25GBase-X card?

The PCI Express 3.0 x8 host interface caps bidirectional throughput at the lane bandwidth of the slot.

How much heat does the FFRM-N322-DA0 add when running 25G all day?

As a passive plug-in card without an onboard fan, it relies on server chassis airflow to dissipate the heat generated by the 25GBase-X PHY and SFP28 optics.
