Product line
Eleven cards from 10/100 to 40 gigabit. Fibre and copper, open cages and fixed optics, plus USB and SATA expansion for machines that ran out of ports.
PCIe x8
A single 10G port with an open SFP+ cage, so the optic is your choice — 10GBase-SR over multimode, 10GBase-LR over single-mode, or a direct-attach cable inside the rack. Low-profile bracket included.
PCIe x8
Four 10G ports in a single slot. The density card of the range — it replaces two dual-port cards and frees a slot in a chassis that has none to spare.
PCIe x8
Copper 10G where fibre is not practical. Falls back through 5G, 2.5G, Gigabit and 100M, so it works with switches you already have. Jumbo frames supported.
PCIe x8
Forty gigabits through one slot. Typical use is an uplink from a storage node or a hypervisor host to the spine switch.
PCIe x8
Two 40G ports for redundant uplinks or for a node that carries both storage and cluster traffic without sharing a link.
PCIe x4
Four Gigabit ports in one slot. The workhorse card for firewalls, routers and virtualisation hosts that need more interfaces than the board provides.
PCIe x1
A direct fibre connection to a Gigabit multimode network, up to 550 metres. Fixed SC optics — nothing to specify, nothing to lose.
PCIe x1
The same Gigabit fibre link, but with an open SFP cage — pick the optic for the distance and the fibre you actually have.
PCIe x1
A plain 10/100 port for industrial and legacy equipment, where the requirement is a working interface on a supported driver rather than bandwidth.
PCIe x4
Ten-gigabit USB on a machine that predates it. Optional SATA power input for devices that draw more than the slot provides. Dual-profile bracket.
PCIe x4
Six SATA III ports for building storage on a board that ran out of them. Port multiplier design; drives are presented individually to the operating system.
A different class of product
A hardware security module in PCIe form. Cryptographic keys are generated, stored and used inside the card and never leave it in the clear; the enclosure is tamper-resistant, and an attempt to open it destroys the key material rather than exposing it.
It belongs to a different class from the network cards on this page: the buyer is a security architect rather than a systems integrator, and the selection criteria are certification, key ceremony and audit rather than throughput.
