Aitech C691

Marvell® Prestera® 98DX106 Controller, Unmanaged GbE and PCIe Gen2 Switch

Manufacturer: Aitech
Aitech C691

Aitech’s C691 is a high-performance 3U VPX integrated unmanaged Gigabit Ethernet and PCI Express Switch for embedded and harsh environment applications. Gigabit Ethernet switching is performed by the Marvell Prestera® 98DX106. The Ethernet switch is unmanaged and does not require any user configuration.

PCIe switching of up to 20 ports/24 lanes is performed by the IDT 89H32NT24AG2 Gen2 PCIe switch, which provides powerful switching capabilities and integrated DMA engines for fast data transfers between VPX cards. Flexible configuration options allow setting of different port/lane combinations and allocations for transparent and non-transparent ports.
