Mellanox 2-port 10Gb Ethernet Expansion Card (CFFh) for IBM BladeCenter

Quality of service
Resource allocation per application or per VM is provided by the advanced QoS supported by
ConnectX-2 EN. Service levels for multiple traffic types can be based on IETF DiffServ or IEEE 802.1p/Q,
along with the Data Center Bridging enhancements, allowing system administrators to prioritize traffic by
application, virtual machine, or protocol. This powerful combination of QoS and prioritization provides the
ultimate fine-grained control of traffic, ensuring that applications run smoothly in today’s complex
environment.
