Dual Port Network Connection

Whether you need to add more Gigabit Ethernet ports to your server for improved performance and reliability or the ability to connect your computer to more networks, get a Sonnet Presto™ Gigabit Server PCIe dual-port Gigabit Ethernet adapter card for for an advanced networking solution! This 4-lane (x4) PCI Express card supports link aggregation (teaming)(1) on its own and with your computer’s onboard Gigabit Ethernet ports and full duplex communication to achieve up to 2000 Mbps and faster transfer rates—the ideal solution for high-bandwidth data transfer requirements. Presto Gigabit Server PCIe also supports 9000 byte jumbo packet transfers (compared to 1500 byte standard packets) to support higher performance and reduced overhead when transferring large files.

Presto Gigabit Server PCIe Usage

Whether you need to add more Gigabit Ethernet ports to your computer for improved performance and reliability or the ability to connect to more networks, get a Sonnet Presto Gigabit Server PCIe dual-port Gigabit Ethernet adapter card for PCI Express for an advanced networking solution!


Key Features

Simple way to add dual-port Gigabit Ethernet connectivity to any compatible computer

Supports gigabit speeds on common CAT-5e cabling—no need for costly cable replacement

Supports link aggregation(1) on its own and with onboard Gigabit Ethernet ports

Supports transparent failover

Full/half duplex

1000/100/10BaseT auto-negotiation

PCI Express (PCIe) x4 host bus interface for maximum performance


Should a cable get unplugged or a port fail, Presto Gigabit Server PCIe provides transparent failover protection, so your computer remains connected to the network.

Presto Gigabit Server PCIe supports gigabit speeds over common CAT-5e cabling, so costly cable replacement is unnecessary. If your computer already has onboard Gigabit Ethernet, you can add a Presto Gigabit Server PCIe and use it for dedicated connection to a printer, AirPort® Extreme base station, DSL or cable modem, or a video server, while leaving your onboard Gigabit Ethernet port(s) available for other connections.

Presto Gigabit Server PCIe is compatible in Mac Pro® towers, Xserve(3), PCs, and servers with a PCI Express (PCIe) slot. Offering simple configuration, this Sonnet card is easy to use, and its support for 1000/100/10BaseT auto-negotiation and full/half duplex communication enable it to be used in most networks.
