The Supermicro AOC-MGP-i2 and AOC-MGP-i4 are add-on cards designed as flexible I/O networking options, specifically Super I/O Modules (SIOM). These cards are based on the Intel® GbE network controller i350 and are engineered with performance-enhancing features and power management technologies. The AOC-MGP-i2 offers dual-port GbE connectivity, while the AOC-MGP-i4 provides quad-port GbE connectivity, both utilizing RJ45 connectors. They are primarily intended for system integrators, IT technicians, and knowledgeable end-users for installation and use in Supermicro motherboards and server systems equipped with a Super I/O Module slot.
Function Description:
These add-on cards serve as Gigabit Ethernet network adapters, providing reliable and scalable network connectivity. They support 1Gb/s Ethernet connections via RJ45 ports, making them suitable for a wide range of commercial environments. The cards are designed to enhance network performance and efficiency through various features, including load balancing across multiple CPUs and Intel I/O Acceleration Technology (Intel I/OAT). They are compatible with most Network Operating Systems and offer features for remote management via NC-SI (Network Controller Sideband Interface) and asset management.
