HP NC382m Dual Port 1GbE Multifunction BL-c Adapter

Overview

The HP NC382m combines standard Gigabit Ethernet networking, TCP/IP offload engine (TOE) acceleration for Microsoft Windows
2003, and iSCSI boot for Linux into a single adapter. The x4 PCI Express NC382m adapter is supported on all HP BladeSystem ProLiant
c-Class servers in all mezzanine slots. Multiple adapters can be installed per server.

In addition to its Multifunction capabilities, the NC382m adapter ships with advanced server features that ProLiant customers have
come to expect, such as support for failover and load balancing, TCP/IP checksum offloading, large send offloading, Wake-on-LAN,
PXE, jumbo frames, VLAN tagging, QoS, and much more.

2,000 Mbps per port full duplex (4,000 Mbps full duplex, both ports) transfer
rate delivers outstanding network performance that improves response time
and removes bottlenecks across the entire network.

TCP/IP Offload Engine (TOE) for Microsoft Windows 2003 moves the
processing of data in the TCP protocol stack from the server CPU to the
network card, freeing CPU cycles for other duties. The NC382m supports TOE
when Windows TOE Chimney is installed. With TOE, network communications
are improved, and server efficiency is increased.

The iSCSI boot for Linux feature allows the host server (c-Class blade server)
to boot from a remote operating system (OS) image located on a storage area
network (SAN). Coupled with the operating system's iSCSI boot initiator
software, the c-Class server uses an HP provided iSCSI firmware image (iSCSI
boot option ROM) making the remote disk drive appear as a local, bootable C:
drive. The server is configured to connect to and boot from the iSCSI target
disk on the network and download the OS image from the iSCSI target disk.
The HP iSCSI boot solution includes scripts to simplify the installation process.
iSCSI boot is not supported on SLES 11 SP1 x64 and RHEL 5.7 x32 bit.

The NC382m support for jumbo frames (also known as extended frames)
permit an industry standard 9K byte transmission unit (MTU), which is six times
the size of standard 1500 byte Ethernet frame. The NC382m supports jumbo
frames as a way to achieve higher throughput and better CPU utilization.
Jumbo frames are particularly useful for database transfers and tape backups.

IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical
port of the NC382m 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. 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.
