The HP 332T adapter provides 1,000 Mbps Ethernet transfer rate per port (4 Gbps aggregate full duplex)
delivers outstanding network performance that improves response time and removes bottlenecks. The
adapter is an ideal solution for server virtualization and security initiatives or where network segmentation
is required. The total aggregate throughput of 4Gbps 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: The port enumeration on the 332T is from the top down, i.e. the port near the top of the adapter is
port #0 followed by port #1
The HP 332T adapter supports jumbo frames (also known as extended frames), permitting up to a 9K byte
(KB) transmission unit (MTU) when running Ethernet I/O traffic. This is over 5X the size of a standard 1500-
byte Ethernet frame. With jumbo frames, networks can achieve higher throughput performance and
greater CPU utilization. These attributes are particularly useful for database transfer and tape backup
operations.
For overall improved system response, the 332T supports standard TCP/IP offloading techniques
including:
TCP/IP and UDP checksum offload 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.
Up to 17 Message Signaled Interrupt (Extended) provides performance benefits for multi-core servers by
load balancing interrupts between CPUs/cores.
The HP 332T Adapter by Broadcom supports MSI and MSI-X
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port of the HP 332T adapter 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.
Hardware assist for IEEE 1588 and IEEE 802.1AS time synchronization implementations for time sensitive
applications. The HP 332T Adapter by Broadcom supports Precision Time Protocol (PTP).
