Presto 10GbE Server 2-Port is discontinued and replaced by the new Presto 10GbE SFP+ PCIe computer card.

10x the Performance of Gigabit EthernetUltra-Fast 10 Gb/s Network Connection

With increasing demands for greater data transfer speeds and more bandwidth over shared networks, and with specialized applications such as HD video editing using high-performance shared storage systems, 10 Gigabit Ethernet (10GbE) use has skyrocketed. This high-speed wired networking standard offers ten times the performance of Gigabit Ethernet, the common wired network connection included with most computers today. Sonnet offers a powerfully simple way to add dual-port 10GbE connectivity to your Mac Pro® tower or Windows® PC—the Presto 10GbE Server 2-Port.(1)

Bandwidth & CPU UsageThe Presto 10GbE Server 2-Port 10 Gigabit Ethernet PCI Express 2.0 adapter card enables you to connect your computer to high-speed infrastructure and storage without stepping down in speed. Setup is simple—install the low-profile card into an available x8 or x16 PCIe slot in your computer, install a driver, connect to the switch or 10GbE port via LC fiber optic or copper cable (all sold separately), and then configure the card through the OS X® Network control panel or Windows Device Manager. This Sonnet solution is perfect for high-performance computing where low latency, high bandwidth, and low CPU overhead are required. xMac mini Server Connected to Network SwitchIts increased throughput performance and low host-CPU utilization are achievedwith stateless offloads, allowing your computer to perform better while large files transfers or high I/O operations take place.With its dual ports, this Sonnet adapter supports transparent failover to keep your computer connected in case a single cable is disconnected or one of the ports fails. When used with a Mac computer, it even supports link aggregation!

Key Features

Provides 10GbE Connectivity to Mac Pro Towers and Windows PCs—Powerfully simple way to add high-performance 10GbE connectivity to your computer with PCIe slots

Connection Flexibility—Choose either two short-range or two long-range SFP+ transceivers (sold separately), or two SFP+-terminated “Direct Attach” twinax copper cables (sold separately) to connect the Presto card to your network or storage

Simple Setup—Low-profile x8 PCI Express 2.0 card installs into an available slot, provides a simple driver installation, and configures through OS X Network control panel or Windows Device Manager

Supports Transparent Failover—Keeps your computer connected in case a single cable is disconnected or one of the ports fails

Supports Link Aggregation with Mac Computers—Increases throughput beyond what a single connection can sustain

Optimized for Thunderbolt—Ideal for use in Sonnet's Echo™ Express Thunderbolt 2 desktop and rackmount expansion chassis, and xMac™ Thunderbolt 2 rackmount servers


Flexibility of Short-Range or Long-Range SFP+ Transceivers

Sonnet offers two SFP+ transceiver options (sold separately), a short-range module (up to 300 meters, part number G10E-SFP-SR), and a long-range module (up to 10 kilometers, part number G10E-SFP-LR) that connect the Presto card via LC fiber optical cable (sold separately) to a network switch or storage. Also, there is the ability to use cost-effective direct-attached copper up to 7 meters (sold separately).
