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.
For overall improved system response, the NC382m supports standard TCP/IP offloading techniques including:
TCP/IP 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.
Interrupt coalescing (interrupt moderation) groups multiple packets, thereby reducing the number of interrupts sent to the host. This process optimizes host efficiency, leaving the CPU available for other duties.
Dual address cycles (DAC) provide the ability to address memory above 4 GB and improve system performance by preventing the server operating system from performing a buffer copy from below 4 GB to above 4 GB.
The two ports on the NC382m are transmitted to separate enclosure interconnect bays providing redundant signal paths.
With multiple dual port adapters supported per server connected to up to two redundant pairs of interconnect modules per enclosure, a very wide variety of high availability I/O configurations are possible.
ProLiant Network Adapter Teaming provides fault tolerance and load balancing across a team of two or more network adapters. The team of adapters works together as a single virtual adapter. Support for several different types of teaming is included. Teaming offers IT professionals an easy, efficient, and cost-effective way to provide network fault tolerance and increased network bandwidth.
