Product Description
PCI Express x4 Dual Port Copper Gigabit Ethernet Server Adapter (Intel 82576 Based)High-performing, 10/100/1000 Ethernet connectionReliable and proven Gigabit Ethernet technology from Intel CorporationScalable PCI Express interface provides dedicated I/O bandwidth for I/O-intensive networking applicationsOptimized for virtualized environmentsFlexibility with iSCSI BootThe Multi-Port Server Adapter is PCIe GbE network adapters. Built with the Intel 82576 Gigabit Ethernet Controller, these new adapters showcase the next evolution in GbE networking features for the enterprise network and data center. These features include support for multi-core processors and optimization for server virtualization.Designed for Multi-Core ProcessorsThe I/O technologies on a multi-core platform make use of the multiple queues and multiple interrupt vectors available on the network controller. These queues and interrupt vectors help in load balancing the data and interrupts amongst themselves in order to lower the load on the processors and improve overall system performance. For example, depending upon the latency sensitivity of the data, the low level latency interrupts feature can bypass the time interval for specific TCP ports or for flagged packets to give certain types of data streams the least amount of latency to the application.Optimized for VirtualizationThe Multi-Port Server Adapter showcase the latest virtualization technology called Intel® Virtualization Technology for Connectivity (Intel® VT for Connectivity). Intel VT for Connectivity is a suite of hardware assists that improve overall system performance by lowering the I/O overhead in a virtualized environment. This optimizes CPU usage, reduces system latency, and improves I/O through- put. Intel VT for Connectivity includes:●  Virtual Machine Device Queues (VMDq) ●  Intel® I/O Acceleration Technology1 (Intel® I/OAT)Use of multi-port adapters in a virtualized environment is very important because of the need to provide redundancy and data connectivity for the applications/workloads in the virtual machines. Due to slot limitations and the need for redundancy and data connectivity, it is recommended that a virtualized physical server needs at least six GbE ports to satisfy the I/O requirement demands.Virtual Machine Device queues (VMDq) VMDq reduces I/O overhead created by the hypervisor in a virtualized server by performing data sorting and coalescing in the network silicon. 2 VMDq technology makes use of multiple queues in the network controller. As data packets enter the network adapter, they are sorted, and packets traveling to the same destination (or virtual machine) get grouped together in a single queue. The packets are then sent to the hypervisor, which directs them to their respective virtual machines. Relieving the hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.These dual-port adapters provide high-performing, multi-port Gigabit connectivity in a multi-core platform as well as in a virtualized environment. In a multi-core platform,the adapters support different technologies such as multiple queues, receive-side scaling, MSI-X, and Low Latency Interrupts, that help in accelerating the data across the platform, thereby improving application response times.PCIe Gigabit adapter provides improved performance with the next-generation VMDq technology, which includes features such as loop back functionality for inter-VM communication, priority-weighted bandwidth management, and doubling the number of data queues per port from four to eight.It now also supports multicast and broadcast data on a virtualized server.Intel I/O Acceleration TechnologyIntel I/O Acceleration Technology (Intel I/OAT) is a suite of features that improves data acceleration across the platform, from networking devices to the chipset and processors, which help to improve system performance and application response times. The different features include multiple queues and receive-side scaling, Direct Cache Access (DCA), MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others. Using multiple queues and receive-side scaling, a DMA engine moves data using the chipset instead of the CPU. DCA enables the adapter to pre-fetch data from the memory cache, thereby avoiding cache misses and improving application response times. MSI-X helps in load-balancing I/O interrupts across multiple processor cores, and Low Latency Interrupts can provide certain data streams a non-modulated path directly to the application. RSS directs the interrupts to a specific processor core based on the application's address.Single-Root I/O Virtualization (SR-IOV)For mission-critical applications, where dedicated I/O is required for maximum network performance, users can assign a dedicated virtual function port to a VM. The controller provides direct VM connectivity and data protection across VMs use SR-IOV. SR-IOV technology enables the data to bypass the software virtual switch and provides near-native performance. It assigns either physical or virtual I/O ports to individual VMs directly.This technology is best suited for applications that demand the highest I/O throughput and lowest-latency performance such as database, storage, and financial applications.The PCI-SIG SR-IOV capability is a mechanism for devices to advertise their ability to be directly assigned to multiple virtual machines. This technology enables the partitioning of a PCI function into many virtual interfaces for the purpose of sharing the resources of a PCI Express* (PCIe) device in a virtual environment. These virtual interfaces are called Virtual Functions. Each virtual function can support a unique and separate data path for I/O- related functions within the PCI Express hierarchy. Use of SR-IOV with a networking device, for example, allows the bandwidth of a single port (function) to be partitioned into smaller slices that may be allocated to specific VMs, or guests, via a standard interface.End-to-end Wired SecurityThe Multi-Port Server Adapter is PCIe adapters to provide authentication and encryption for IPsec and LinkSec. LinkSec is already designed into the network adapter hardware.These adapters are future-proof and prepared to provide LinkSec functionality when the ecosystem supports this new technology.IPsec provides data protection between the end-point devices of a network communication session. The IPsec offload feature is designed to offload authentication and encryption of some types of IPsec traffic and still delivers near line-rate throughput and reduced CPU utilization.LinkSec is an IEEE industry-standard feature that provides data protection in the network.The IEEE 802.3ae and IEEE 802.3af protocols provide hop-to-hop data protection between two network devices in the transaction line between the host and destination. The two network devices must support the LinkSec technology. The network devices could be servers, switches, and routers.Features;GeneralIntel 82576 Gigabit Ethernet Controller Low-profileiSCSI remote boot supportLoad balancing on multiple CPUsCompatible with x4, x8, and x16 standard and low-profile PCI Express* slotsMulti-port designSupport for most network operating systems (NOS)Intel PROSet Utility for Windows Device ManagerRoHS-compliant3I/O Features for Multi-Core Processor ServersMultiple queues & receive-side scalingMSI-X supportLow Latency InterruptsHeader splits and replication in receiveMultiple queues: 8 queues per portTx/Rx IP, SCTP, TCP, and UDP checksum offloading (IPv4, IPv6) capabilitiesTx TCP segmentation offload (IPv4, IPv6)Receive and Transmit Side Scaling for Windows* environment and Scalable I/O for Linux* environments (IPv4, IPv6, TCP/UDP)IPsec OffloadLinkSecVirtualization FeaturesVirtual Machine Device queues2 (VMDq)Next-generation VMDqIPv6 offloadingAdvanced packet filteringVLAN support with VLAN tag insertion, stripping and packet filtering for up to 4096 VLAN tagsPC-SIG SR-IOV Implementation (8 virtual functions per port)Manageability FeaturesOn-board microcontrollerAdvanced filtering capabilitiesPreboot execution Environment (PXE) SupportSimple Network Management Protocol (SNMP) and Remote Network Monitoring (RMON) Statistic CountersWake-on-LAN supportiSCSI bootWatchdog timerIEEE 1588 precision time control protocolNetwork Operating Systems (NOS) Software SupportWindows 2000Windows XPWindows Vista 32-bit (64-bit)Windows 7 32-bit (64-bit)Windows 8 32-bit (64-bit)Windows Server 2003 32-bit (64-bit)Windows Server 2008 32-bit (64-bit)Windows Server 2008 R2 32-bit (64-bit)Windows Server 2012 R2 32-bit (64-bit)Novell Netware 5.x、6.xLinux kernel version 2.6.x,3.x or greater (x86_64) (w/ SR-IOV support)FreeBSD 7.x or lasterDOSNovell ODIOS 8 or lasterSCO Open ServerUnixWare / OpenUnix 8Sun Solaris x86OS IndependentVMware ESXPS: The above details are only for reference, if there are any changes, no inform will have.
