The Intel I350T2V2 Dual-Port PCIe Gigabit Ethernet Server Adapter features the bridgeless Intel Ethernet Controller I350 and is suitable for both virtualized and iSCSI unified networking environments. This adapter includes power management technologies such as Energy Efficient Ethernet (EEE) and DMA Coalescing (DMAC). The adapter includes Intel Virtualization Technology for connectivity to deliver I/O virtualization and Quality of Service (QoS) features designed directly into the controller on the adapter.
With Flexible Port Partitioning (FPP), virtual controllers can be used by the Linux host directly and/or assigned to virtual machines. With this port partitioning, administrators can create up to 8 dedicated connections on a single Ethernet port for use in bare-metal and virtualized server deployments. In a bare-metal Linux server, host processes can be assigned to dedicated network resources to provide traffic isolation and balanced bandwidth allocation. In a virtualized environment, a VM can be assigned to a virtual controller to reduce the CPU overhead seen when using a software-based network bridge by offloading network traffic management to the controller.
This Ethernet server adapter with native iSCSI initiators built into Microsoft Windows, Linux, and VMware ESX platforms provides a simple way to connect to iSCSI SANs. These native initiators are broadly tested using multiple generations of operating systems, storage systems, and OS tools to help ensure reliability and ease of use. In addition, this adapter includes a number of hardware features designed to accelerate iSCSI traffic and enhance data processing. TCP segmentation offload and checksum offload capabilities help reduce processor usage, increase throughput, and deliver exceptional iSCSI performance. Using native OS initiators, it supports the CRC-32 digest instruction set included with Intel Xeon processor products, which improves transmission reliability and delivers an enterprise class iSCSI solution.
Advanced Power Management Technologies (PMTs) in the Ethernet Server Adapter I350 enables enterprises to configure power options on the adapter and more effectively manage their power consumption. The adapter supports the IEEE802.3az Energy Efficient Ethernet (EEE) standard so that, during periods of low network activity, EEE reduces the power consumption of an Ethernet connection by negotiating with a compliant EEE switch port to transition to a low power idle (LPI) state. This reduces the controller power to approximately 50% of its normal operating power, saving power on the network port and the switch port. As soon as increased network traffic is detected, the controller and the switch quickly come back to full power to handle the increased network traffic. EEE is supported for both 1000BASE-T and 100BASE-TX.
The adapter also features DMA Coalescing (DMAC) power saving. Based on the configurable DMAC settings, incoming packets are buffered momentarily before any DMA calls are made. This enables the controller to intelligently identify opportunities to batch multiple packets together so that when components are wakened from lower power states they can efficiently handle the batched packets at the same time. This enables platform components to remain in lower power states longer, which reduce platform energy consumption. DMAC synchronizes DMA calls across all controller ports to ensure maximum power savings.
