IBM continues to enhance its Ethernet adapter offerings by introducing the PRO/1000 XT Server Adapter by Intel. This new adapter features PCI-X gigabit capability over industry standard Category 5 copper cabling via an RJ-45 port. The PCI-X protocol is a high-performance extension to the existing PCI Local Bus. The adapter with PCI-X technology provides increased bandwidth and bus performance needed to address I/O demands from enterprise applications including Gigabit Ethernet.The adapter allows for auto speed configuration to 10, 100 or 1000 Mbps. This product supports adapter failover, load balancing, link aggregation, packet prioritization, and IP security, offering uninterrupted network performance, optimized network throughput and quality of service data delivery with security, confidentiality and authenticity for IP traffic. Enhanced server functions include adapter fault tolerance, which helps the server maintain network connectivity and service (even if there is a cable or adapter failure) by automatically transferring data from the failed adapter to an alternate adapter. The adapter eases IT administration and helps reduce support needs with advanced management capabilities.
