Quad-port 1 Gigabit
Ethernet Throughput
The HP 366FLR adapter provides 8 Gbps aggregate full duplex, delivering outstanding network
performance that improves response time and removes bottlenecks. Four ports on a single adapter are
ideal for high density, I/O slot constrained servers, virtualization, security, applications, server
consolidation, and increased network segmentation. The 8Gbps full-duplex aggregate throughput meets
the needs for customers desiring high bandwidth but are not yet ready to move to 10 Gigabit Ethernet.
NOTE:
Port enumeration on the 366FLR is from the bottom up, i.e. the port closest to the gold teeth is port
#1 and the port near the top of the adapter is port #4.
Jumbo Frames
The HP 366FLR FlexibleLOM supports jumbo frames, permits up to a 9.5K byte (KB) transmission unit
(MTU) when running Ethernet, which is over five times the size of standard 1500-byte Ethernet frame.
Jumbo frames can help achieve higher throughput and better CPU utilization and are particularly useful for
database transfer and tape backup operations.
MSI and MSI-X
Up to 25 Message Signaled Interrupt (Extended) vectors per port provides performance benefits for multi-
core servers by load balancing interrupts between CPUs/cores.
802.1Q VLANs
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP 366FLR to be
separated into multiple virtual NICs 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 HP 366FLR supports TCP, IPv4, UDP checksum offload, Large
Send Offload (LSO), and Segmentation Offload (TSO). These features optimize host efficiency, leaving the
CPU available for other duties.
Time synchronization
(IEEE 1588)
Hardware assist for IEEE 1588 and IEEE 802.1AS time synchronization implementations for time sensitive
applications.
Optimized for
Virtualization
Intel Virtualization Technology for Connectivity provides I/O Virtualization support for VMware NetQueue
and Microsoft VMQ help meet the performance demands of consolidated virtual workloads.
Energy Efficient Ethernet
Compliant with IEEE 802.3az, featuring advanced power savings by throttling power usage with network
load activity (with compatible link partner).
