Everyday there are events that occur in businesses that affect how its computing and networking resources are best utilized. Organizations want to be able to handle and take advantage of change today
to improve their competitiveness, lower costs, and serve their customers better – and build an IT environment that can easily accommodate tomorrow's changes. Whether it's consolidating servers,
moving workloads between systems, or re-hosting applications on larger servers during anticipated spikes, having a network infrastructure that's able to adapt quickly to these changing service level
demands becomes a winning advantage.

HP understands these business challenges and is committed to providing an array of high quality industry standard technology solutions that provide superior price/performance and investment
protection for tomorrow. Two such solutions are the next generation in the Ethernet family of products, namely, HP PCI-X 133MHz and PCI-X 266MHz 10 Gigabit Ethernet Short Range Fiber adapter.
The demand for higher speed networks coupled with the pervasiveness of Ethernet deployments over the past 30 years, resulted in the creation of 10 Gigabit Ethernet IEEE 802.3ae standards. As
businesses run more compute intensive applications or connect more clients and devices to the network, and as these applications/clients/devices need to communicate with servers at the same time,
these servers will experience increasing demand for higher IO bandwidth. HP 10 Gigabit Ethernet (10GbE) is a flexible cost-effective solution that can quickly relieve Gigabit Ethernet networks that
are, or will soon be, reaching saturation.
HP's leading edge PCI-X 10 Gigabit Ethernet adapter provides exceptional bandwidth in one large pipe and supports many of the innovative features provided by its Gigabit Ethernet predecessor. In the
future, because of its high bandwidth and flexible nature, HP PCI-X 10 Gigabit Ethernet will play a vital role for paving the road to a unified fabric infrastructure; where network, clustering and
storage can coexist all over one medium; simplifying management, increasing reliability and reducing total cost of ownership.
10GbE customers will recognize immediate gains from:
- standards based IEEE 802.3ae ensures consistency across the strong ecosystem
- 64-bit PCI-X capability provides faster transmissions with lower CPU utilization
- 64-bit Management Information base (MIB) statistics allows data link service (DLS) to return 64-bit statistics
- bidirectional bandwidth that can deliver up to 7.5 Gb/s, (PCI-X 133MHz) and up to 9.7 Gb/s (PCI-X 2.0 266MHz)
- IEEE conformance for use of multi-mode fiber, supporting operating distances from 7' to 984' (2 to 300 meters)
- quality engineered Protocol offload algorithms that maximize host efficiencies and optimize bus utilizations by reducing host processing loads
- modular design that can support various connectivity options and sw enhancements
- rapid and flexible deployments requiring minimal training, due to leveraged Ethernet knowledge
Key performance and manageability features/benefits include:
- substantial bandwidth in one large pipe; 10GbE can be as an uplink to overcome existing Gigabit Ethernet bottlenecks
- TCP Segmentation Offload (TSO) and Checksum Offload (CKO) allow segmentation & error checking to be handled by the adapter itself; thus saving CPU cycles when sending large amounts of data
over the network
- jumbo frame support for transferring data at MTU of 9000 bytes, as opposed to the default 1500 bytes; jumbo frames reduces the CPU overhead by reducing the number of frames processed
- high performance is achieved with less complexity than aggregating multiple GbE NICs
- increased bandwidth speeds back-ups and point-to-point configuration transfers
- HP Virtual LAN (VLAN) support - Physical LANs can be segmented into smaller logical or "virtual" LANS, allowing broadcast traffic to be reduced, thereby improving overall network performance
- Configuration through HP's graphical user interface (SAM) or via command line
High Availability features for 10GbE are provided through:
- OnLine Addition and Replacement (OLAR) enables adapters to be added, deleted and replaced while the system continues to run
- Transparent load-balancing - Dynamically1 rebalances service to match workload performance requirements and/or failure events
- Support of MC/Serviceguard - ensures Mission Critical IT demands are fulfilled
- APA LAN MONITOR mode is supported for 10GbE2
110GbE Aggregation is not supported
2Dynamic load balancing apply with LAN MONITOR configured
