Kit Contents

The HPE Ethernet 1Gb 4-port 331FLR Adapter for select HPE ProLiant Gen8 rack servers features the next generation of Ethernet
integration, offering a single-chip solution in a FlexibleLOM form factor, which offers the option for future upgrades to 10GbE
networking speeds. It delivers full line-rate performance across all ports with low power consumption.
The HPE 331FLR is ideal for virtualization, security, server consolidation, network segmentation, and other applications requiring
maximum throughput and port density. The total aggregate throughput of 4Gb meets the needs of customers desiring high
bandwidth.
The HPE 331FLR supports advanced features such as Large Send and Receive offload capability, TCP checksum and segmentation,
VLAN tagging, MSI-X, jumbo frames, IEEE 1588, HPE Sea of Sensors 3D and virtualization features such as VMware NetQueue and
Microsoft VMQ.

Jumbo Frames

The

331FLR FlexibleLOM supports jumbo frames, permits up to a 9K byte (KB) transmission unit (MTU)
when running Ethernet, which is over five times the size of standard 1500
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 17 Message Signaled Interrupt (Extended) provides performance benefits for multi
balancing interrupts between CPUs/cores.

802.1Q VLANs

IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the
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
