The 20,000 Mbps full duplex Ethernet transfer rate per port (40 Gbps aggregate full duplex) delivers
outstanding network performance that improves response time and removes bottlenecks for the next
generation data center. 10 Gigabit Ethernet bandwidth is ideal for financial services, high performance
computing, database clusters, iSCSI storage, storage backups, grid systems, virtualization, server and I/O
consolidation, fabric consolidation, and more.
The HP 570FLR-SFP+ Adapter is designed with an eight lane (x8) PCI Express bus based on the PCIe v2.0
The HP 570FLR-SFP+ Adapter supports jumbo frames (also known as extended frames), permitting up to a
9K byte (KB) transmission unit (MTU) when running Ethernet I/O traffic. This is over 5X the size of a
standard 1500-byte Ethernet frame. With jumbo frames, networks can achieve higher throughput
performance and greater CPU utilization. These attributes are particularly useful for database transfer and
tape backup operations.
For overall improved system response, the HP 570FLR-SFP+ adapter supports standard TCP/IP offloading
TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the
Large Send Offload (LSO) or TCP Segmentation Offload (TSO) allows the TCP segmentation to be
handled by the adapter rather than the CPU. TCP, IP, UDP checksum offload, Large Send Offload
(LSO), TCP, Segmentation Offload (TSO). These features optimize host efficiency, leaving the CPU
available for other duties.
Interrupt coalescing (interrupt moderation) groups multiple packets, thereby reducing the number of
interrupts sent to the host. This process can optimize host efficiency by improving peak throughput and
reducing CPU utilization.
Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load
balancing interrupts between CPUs/cores. The HP 570FLR-SFP+ Adapter supports MSI and MSI-X.
