IRVINE, CA—August 12, 2008—Sonnet Technologies, a leader in upgrades and useful accessories for Apple® Mac® desktop, server, and notebook computers, announces the introduction of the Presto™ Gigabit PCIe Server PCI Express® network adapter card and the Presto Gigabit PCI-X Server network adapter card. These Sonnet cards add two Gigabit Ethernet ports to any compatible computer, offer enhanced performance through support for jumbo packet data transfers and link aggregation, and deliver improved reliability with transparent failover protection in case a cable gets disconnected or a port fails.

Presto Gigabit PCIe Server features a native PCI Express x4 host bus interface for maximum performance in most recent computers, while Presto Gigabit PCI-X Server features a 64-bit, 133 MHz PCI-X host bus interface for maximum performance and even wider compatibility in older computers. Both Presto Gigabit Server network adapter cards deliver enhanced networking support in compatible computers and gigabit speeds over common CAT-5 cabling, so costly cable replacement is unnecessary to support the higher performance. Presto Gigabit Server network adapter cards’ 1000/100/10BaseT auto-negotiation and full/half duplex communication support allow them to be used in most networks.
