Product Description
The Lenovo 00JY821 is a high-performance dual-port 10 Gigabit Ethernet adapter based on Emulex's Virtual Fabric Adapter (VFA) technology. Designed specifically for Lenovo servers, this adapter provides robust and efficient network connectivity essential for modern data centers and enterprise applications. It connects via a PCI Express interface, ensuring sufficient bandwidth to support the demanding throughput of 10Gb/s Ethernet connections. The adapter features two SFP+ (Small Form-factor Pluggable Plus) ports, offering flexibility in network connectivity. Users can choose between fiber optic transceivers for extended reach or Direct Attach Copper (DAC) cables for shorter, high-density connections within racks. This SFP+ interface is standard for 10GbE and allows for easy integration into existing network infrastructure. As a Virtual Fabric Adapter (VFA), the Emulex VFA5 technology integrated into the 00JY821 often includes advanced features such as Single Root I/O Virtualization (SR-IOV) and various offload capabilities. These features are crucial for virtualized environments, as they improve network performance, reduce CPU overhead, and enhance I/O efficiency by allowing virtual machines direct access to the network hardware. This makes the Lenovo 00JY821 an ideal choice for servers running virtualization platforms or handling high-volume network traffic.
