1. PCIe x8 Broadcom BCM57840 four optical port 10G SFP+server optical network card controlled by Broadcom BCM57,840 chip 2. BCM57840 supports the segmentation of a single 10 Gb Ethernet port into up to eight , enabling dynamic bandwidth allocation to the workload requirements of applications, thus ensuring efficient utilization of 10 GbE links. 3. BCM57840 converges a flexible motherboard LAN networking solution for 10 Gigabit server networks. It supports NIC zoning of the switch, allowing administrators to divide a single network port into up to four zones and allocate bandwidth as needed. 4. High performance - provides the highest level of performance for mission critical enterprises and -scale data centers. 5. NIC zoning - Helps manage 10 GbE bandwidth allocation for virtual machines and applications.
