Sun 540-2989 Dual Gigabit Host Bus Adapter

Product Description

The Sun 540-2989 is a Dual Gigabit Ethernet Host Bus Adapter (HBA) designed to enhance the network connectivity of Sun Microsystems servers and workstations. This adapter features two independent Gigabit Ethernet ports, each capable of operating at speeds of 10/100/1000 Mbps. By providing multiple high-speed network interfaces, the 540-2989 enables significant improvements in network throughput and allows for the implementation of network redundancy and load balancing strategies. As a Host Bus Adapter, it connects directly to the server's PCI bus, providing a dedicated pathway for network traffic that can reduce latency and improve overall system performance compared to integrated network controllers. This makes it particularly suitable for demanding server environments where high network I/O is critical, such as file servers, application servers, and database servers. The dual-port design offers flexibility in network configuration. Administrators can use the second port for failover purposes, ensuring network connectivity remains active even if one link fails. Alternatively, traffic can be aggregated across both ports to increase bandwidth, or different network segments can be connected to the server through a single adapter. The Sun 540-2989 is a robust solution for expanding and optimizing network capabilities in enterprise-class systems.
