Product Details

The NC550SFP ships with advanced server features that ProLiant customers have come to expect, such as support for TCP checksum and segmentation, Large Send and Large Receive offload capability, VLAN tagging, 9K jumbo frames, IPv4 and IPv6, teaming for failover and load balancing, and TCP/IP Offload for Windows.

Its PCI Express Gen 2 adapter ships with two SFP+ (Small Form-factor Pluggable) cages suitable for connecting to Direct Attach Cable (DAC) or an SR fiber module supporting fiber optic cabling.


NC550SFP protocol speed of 10Gbps meets the needs of the most demanding ProLiant Server workloads

  • Dual Ports: Saves valuable I/O slots
  • Full Duplex, Bi-directional Modes of Operation: A total of 40Gbps theoretical maximum throughput

Workloads created by virtualization require the increased I/O delivered by the 10GbE NC550SFP.

  • More Virtual Machines per Physical Server: The number of virtual machines continues to go up, and this trend is expected to continue.
  • More Virtual Machines Require More Virtual I/O: From a server perspective, the capacity to support increased workloads comes partly from the number of I/O ports attached to the server. This gives rise to the need for more networking bandwidth offered by the NC550SFP

SFP+ ports on the NC550SFP can be used in either copper or fiber-optic environments.

  • Supports Direct Attach Cable (DAC): A cost-effective interface for 10GbE networking across a copper infrastructure
  • Qualified for SR Fiber Transceivers: Short haul fiber environments are fully supported
  • Reduce Cabling: By deploying 10GbE networking, customers can reduce the cabling requirements throughout their infrastructure

10 Gigabit networking prepares an infrastructure for 10GbE converged network fabrics.

  • Future-proof the Infrastructure with 10GbE NICs: Networking bottlenecks can be avoided with the 10GbE bandwidth available from the NC550SFP
  • Converged Infrastructures on the Horizon: A Converged Infrastructure enables next generation data center environment under a single fabric.
  • No More Silos: In the future, the Converged Infrastructure will integrate traffic between servers, storage, management and networking over a single converged fabric. All made possible by 10GbE networking, this not only simplifies the infrastructure, it increases flexibility for better business decisions.
