Ethernet
Throughput
(theoretical
bandwidth)
The 20 Gbps full duplex Ethernet transfer rate per port (40 Gbps aggregate full duplex) delivers outstanding
network performance that improves response time and removes bottlenecks.
Jumbo Frames
The HPE 570M adapter supports jumbo frames (also known as extended frames) with a maximum
transmission unit (MTU) of up to 9.5K bytes when running Ethernet and/or, which is over five times the size
of standard 1500-byte Ethernet frame. Jumbo frames can help achieve higher throughput and better CPU
utilization. Jumbo frames are particularly useful for database transfers.
MSI and MSI-X
Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by load
balancing interrupts between CPUs/cores
Interrupt
Coalescence
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.
802.1p QoS Tagging
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.
802.1Q VLANs
The HPE 570M adapter supports the IEEE 802.1Q virtual local area network (VLAN) protocol that allows each
physical port to be assigned to a VLAN for added network segmentation and enhanced security and
performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to
within the same VLAN domain also improves performance.
TCP/IP Stateless
Offloading
For overall improved system response, the HPE 560M adapter supports standard TCP/IP stateless offloading
techniques including:
•
TCP/IP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU to the
