Ethernet Card Sonnet Presto 10GbE G10E-2X-E3
The Sonnet Presto 10GbE G10E-2X-E3 is an internal PCIe 3.0 Ethernet card that delivers 10 Gigabit (10GBASE-T) wired networking for Mac Pro, Windows PCs, and Linux servers. It provides dual copper RJ-45 ports for high-speed connections using CAT‑6 or CAT‑6A cabling and is compatible with standard x4 or larger PCIe slots. This card is suited for workstations and servers that require higher throughput, lower latency, and efficient CPU usage during large file transfers and high I/O operations.
The Presto 10GbE offers ten times the throughput of Gigabit Ethernet while maintaining low host CPU utilization through stateless offloads (TCP, UDP, IPv4 checksum), flow control, and 64-bit addressing support. Dual ports allow transparent failover and link aggregation (teaming) for redundancy and increased bandwidth. Wake-on-LAN is supported for remote power management. Installation is straightforward: insert into a PCIe x4 or larger slot and install the provided driver.
Power down the computer and install the low-profile card into an available PCIe x4 (or larger) slot. Boot the system, install the appropriate driver for your operating system, then connect the card to a 10GbE switch or device using CAT‑6 or CAT‑6A copper cable. Configure IP settings and network options through the OS network control panel (macOS) or Device Manager and network settings (Windows) or the equivalent tools on Linux. For systems without a free PCIe slot, install the card into a Sonnet Thunderbolt-to-PCIe expansion chassis and connect that chassis to the computer via Thunderbolt.
Use CAT‑6A cabling for full 100 m runs or CAT‑6 for shorter links (up to 55 m) to ensure stable 10GbE performance. Enable link aggregation on supported switches and hosts when higher throughput or redundancy is required. Keep drivers up to date to maintain compatibility and optimal CPU offload efficiency.
