Get affordable, full line-rate performance with CAT 6a cabling or better at distances up to 100 meters, support for business and virtualization features, and keep one more PCIe slot available for other use with the HP 10GBASE-T Dual NIC Module Z6/8 G4.
The HP Z 10GbE Dual Port Module supports jumbo frames (also known as extended frames), permitting up to a 9.5K byte (KB) transmission unit (MTU) when running Ethernet I/O traffic. With jumbo frames, networks can achieve higher throughput performance and improve CPU utilization. These attributes are particularly useful for database transfer and tape backup operations.
TCP/IP stateless offloading
TCP, IP, UDP checksum offload, Large Send Offload (LSO), TCP Segmentation Offload (TSO). These features optimize host efficiency, leaving the CPU available for other duties. The HP Z 10GbE Dual Port Module offers TCP/IP stateless offloading capability.
RDMA with iWARP
With the Intel C620 series chipset, the HP Z 10GbE Dual Port Module natively supports a form of Remote Direct Memory Access (RDMA) using Internet Wide Area RDMA Protocol (iWARP). The Intel iWARP support enables three performance-enhancing features: Kernel Bypass - which allows software applications to bypass the OS and directly access the Ethernet adapter resources, Direct Data Placement - which allows data to be written directly into user space, bypassing buffers, and Transport Acceleration - where the TCP/IP and iWARP protocols are accelerated in silicon relative to host software stacks. All of these features equate to reducing latency, freeing up processor cycles, and increasing memory bandwidth.
MSI and MSI-X
Message Signaled Interrupt provides performance benefits for multi-core servers by load balancing interrupts between CPUs/cores. The HP Z 10GbE Dual Port Module supports MSI and MSI-X.
IEEE 802.1Qbg virtual local area network (VLAN) protocol allows each physical port of the HP Z 10GbE Dual Port Module 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. The HP Z 10GbE Dual Port Module provides support for 802.1Q (VLAN) as well as the IEEE 802.1Qbg for VLAN Bridging.
