Produktbeskrivning

The HP Z 10GbE Dual Port Module is a 10GBase-T adapter utilizing the Intel X722 MAC and X557-AT2 PHY pairing to deliver full line-rate performance, utilizing CAT 6A UTP cabling. Providing high-performance Ethernet connectivity, it is ideal for use in workstation, virtual workstation and cloud computing environments. It supports enterprise class features (VLAN tagging, adaptive interrupt coalescing, MSI-X, NIC teaming (bonding), Receive Side Scaling (RSS), jumbo frames, PXE boot) and virtualization features (VMware NetQueue and Microsoft VMQ). The module was developed to be a low-cost option without the need of a PCIe slot, which can help with network transitions to 10G.

 

Egenskaper

Jumbo frames
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.

802.1Q VLANs
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.
