The HP 331T adapter provides 2,000 Mbps full duplex Ethernet transfer rate per port (8 Gbps aggregate
full duplex) delivers 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 and security, applications, server consolidation, and increased network segmentation. The
total aggregate throughput of 8Gbps in full-duplex mode also meets the needs for customers desiring
high bandwidth but are not yet ready to move to 10 Gigabit Ethernet.

NOTE: Port enumeration on the 331T is from the top down, i.e. the port near the top of the adapter is
port #0 and the port closest to the gold teeth is port #3

Jumbo Frames
The 331T adapter support for jumbo frames (also known as extended frames) permits up to a 9K 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.

802.1Q VLANs
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP 331T 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, UDP checksum offload (TCO) moves the TCP and IP checksum offloading from the CPU
to the network adapter.
Large send offload (LSO) or TCP segmentation offload (TSO) allows the TCP segmentation to be
handled by the adapter rather than the CPU.
