Management Support
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 high performance computing, database
clusters, iSCSI storage, storage backups, grid systems, virtualization, server and I/O consolidation, fabric
consolidation, and more.
The NC552SFP is designed with an eight lane (x8) PCI Express bus based on the PCIe v2.0 standard. The
adapter is backward compatible with four lane (x4) PCI Express, automatically auto-sensing between x8
and x4 slots.
Jumbo frames (also known as extended frames) permit a 9,000 byte transmission unit (MTU). The
NC552SFP adapter supports 9KB jumbo frames as a way to achieve higher throughput and better CPU
utilization. Jumbo frames are particularly useful for database transfers and tape backups.
techniques including:
TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the
network adapter.
Large Send Offload (LSO) or TCP Segmentation Offload (TSO) allows the TCP segmentation to be
handled by the adapter rather than the CPU.
Interrupt coalescing (interrupt moderation) groups multiple packets, thereby reducing the number of
interrupts sent to the host. This process optimizes host efficiency, leaving the CPU available for other
duties.
IEEE quality of service (QoS) 802.1p tagging allows the adapter to mark or tag frames with a priority level
across a QoS-aware network for improved traffic flow.
I/O Virtualization support for VMware NetQueue and Microsoft VMQ help meet the performance demands
of consolidated virtual workloads.
Like all HP ProLiant server adapters, the NC552SFP adapter ships with agents that can be managed from
HP Systems Insight Manager or other management application that support SNMP.
