Intel? Ethernet Converged Network Adapter X520

Dual- and Single-Port 10 Gigabit SFP+ Ethernet Converged Network Adapters Provide Ultimate Flexibility and Scalability in Virtual and Unified Storage Environment

在虛擬化和統(tǒng)一存儲環(huán)境中提供極致的靈活性與可伸縮性

Overview

Intel’s family of adapters, the Intel? Ethernet Converged Network Adapter X520 with SFP+ connectivity, are the most flexible and scalable Ethernet adapters for today’s demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gbps connections. Customers require flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications in virtualized and unified storage environments. Powered by Intel’s third-generation 10 GbE network controller, the Intel? Ethernet 82599 10 Gigabit Ethernet Controller, the X520 adapter family addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization, flexibility for LAN and SAN networking, and proven, reliable performance.

Intel 的適配器系列，具有 SFP+ 連接性的英特爾? 以太網(wǎng)融合網(wǎng)絡適配器 X520，是當今要求嚴苛的數(shù)據(jù)中心環(huán)境中最靈活和可擴展的以太網(wǎng)適配器。數(shù)據(jù)中心網(wǎng)絡正被推到極限。具有多核處理器和要求苛刻的應用程序（如高性能計算 (HPC)、數(shù)據(jù)庫集群和視頻點播）的服務器部署不斷升級，正在推動對 10 Gbps 連接的需求?？蛻粜枰`活且可擴展的 I/O 解決方案，以滿足在虛擬化和統(tǒng)一存儲環(huán)境中運行關(guān)鍵任務應用程序的嚴格要求。 X520 適配器系列由英特爾第三代 10 GbE 網(wǎng)絡控制器 Intel? Ethernet 82599 10 Gigabit Ethernet Controller 提供支持，通過提供無與倫比的虛擬化功能、LAN 和 SAN 網(wǎng)絡靈活性，滿足下一代數(shù)據(jù)中心的苛刻需求，和經(jīng)過驗證的可靠性能。

Best choice for virtualization

The explosive growth in virtualization is leading to an increasing demand for network performance. With more Virtual Machines (VMs) running on each multi-core server, networking traffic is dramatically increased, with each VM competing for available I/O bandwidth.

虛擬化的最佳選擇虛擬化的爆炸性增長導致對網(wǎng)絡性能的需求不斷增加。隨著更多虛擬機 (VM) 在每臺多核服務器上運行，網(wǎng)絡流量顯著增加，每個 VM 都在爭奪可用的 I/O 帶寬。

Intel’s family of Intel Ethernet Converged Network Adapter X520 addresses networking bottlenecks in virtualized environments. These adapters enable network-intensive applications to achieve the performance expected in a virtualized environment.

英特爾的英特爾以太網(wǎng)融合網(wǎng)絡適配器 X520 系列解決了虛擬化環(huán)境中網(wǎng)絡的瓶頸。這些適配器使網(wǎng)絡密集型應用程序能夠在虛擬化環(huán)境中實現(xiàn)預期的性能。

The Intel Ethernet X520 family of adapters provides the best networking performance available in the industry, whether the physical port is configured in an emulation mode using the virtual switch in the Virtual Machine Monitor (VMM), or is directly assigned to a virtual machine.

英特爾以太網(wǎng) X520 系列適配器提供業(yè)界最佳的網(wǎng)絡性能，無論物理端口是使用虛擬機監(jiān)視器 (VMM) 中的虛擬交換機配置為仿真模式，還是直接分配給虛擬機。

VMDQ：

In the emulation mode, Intel’s I/O technology, Virtual Machine Device queues1 (VMDq) optimizes network performance by offloading data sorting and copying from the software Virtual Switch in the VMM to the Intel Ethernet 82599 10 Gigabit Controller. This configuration is best suited for a large number of VMs running standard applications that have limited bandwidth and latency requirements.

在仿真模式下，英特爾的 I/O 技術(shù) Virtual Machine Device queues1 (VMDq) 通過將數(shù)據(jù)排序和復制從 VMM 中的軟件虛擬交換機卸載到英特爾以太網(wǎng) 82599 10 千兆位控制器來優(yōu)化網(wǎng)絡性能。此配置最適合運行標準應用程序的大量 VM，這些應用程序具有有限的帶寬和延遲要求。

直接網(wǎng)絡I/O/SR-IOV：

**For mission-critical applications, where dedicated I/O is required for maximum network performance, users can assign a dedicated virtual adapter port to a VM.

對于需要專用 I/O 以實現(xiàn)最大網(wǎng)絡性能的關(guān)鍵任務應用程序，用戶可以為 VM 分配專用虛擬適配器端口。

Using the PCI-SIG SR-IOV capability on an Intel Ethernet X520 adapter provides direct VM connectivity and data protection across VMs.

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, financial and other application.

在英特爾以太網(wǎng) X520 適配器上使用 PCI-SIG SR-IOV 功能可提供跨 VM 的直接 VM 連接和數(shù)據(jù)保護。

SR-IOV 技術(shù)使數(shù)據(jù)能夠繞過軟件虛擬交換機并提供接近本機的性能。

它直接將物理或虛擬 I/O 端口分配給各個 VM。

該技術(shù)最適合需要最高 I/O 吞吐量和最低延遲性能的應用程序，例如數(shù)據(jù)庫、存儲、金融和其他應用程序。

PCI-SIG SR-IOV is a mechanism for devices to advertise their ability to be directly assigned to multiple virtual machines. SR-IOV enables the partitioning of a PCI Express* (PCIe) function into many virtual interfaces for the purpose of sharing the resources of a PCIe device in a virtual environment.

PCI-SIG SR-IOV 是一種機制，用于設備通告其直接分配給多個虛擬機的能力。 SR-IOV 支持將 PCI Express* (PCIe) 功能劃分為多個虛擬接口，以便在虛擬環(huán)境中共享 PCIe 設備的資源。

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 PCIe hierarchy. Use of SR-IOV with a networking device, for example, enables the bandwidth of a single port (function) to be partitioned into smaller slices that can be allocated to specific VMs, or guests, via a standard interface.

這些虛擬接口稱為虛擬功能。每個虛擬功能都可以為 PCIe 層次結(jié)構(gòu)中的 I/O 相關(guān)功能支持唯一且獨立的數(shù)據(jù)路徑。例如，將 SR-IOV 與網(wǎng)絡設備一起使用，可以將單個端口（功能）的帶寬劃分為更小的切片，這些切片可以通過標準接口分配給特定的 VM 或來賓。

The Intel Ethernet X520 family of adapters delivers the same functionality and throughput as ten dual-port, one gigabit adapters, saving cost, power, and complexity. For more information on virtualization please go to:

英特爾以太網(wǎng) X520 系列適配器提供與 十個雙端口、一個千兆位適配器相 同的功能和吞吐量，從而節(jié)省成本、功耗和復雜性。

Application Device Queues (ADQ)

improves application response time predictability using advanced traffic-steering technology

應用程序設備隊列(ADQ)

使用先進的流量轉(zhuǎn)向技術(shù)提高了應用程序響應時間的可預測性

As modern data centers scale, a key challenge is to provide scalable, predictable application-level performance. ADQ technology improves performance scalability and predictability by dedicating queues to key workloads, delivering predictable high performance through dramatically reduced jitter.

隨著現(xiàn)代數(shù)據(jù)中心的擴展，一個關(guān)鍵的挑戰(zhàn)是提供可伸縮的、可預測的應用程序級性能。ADQ技術(shù)通過將隊列專門用于關(guān)鍵工作負載，提高了性能的可伸縮性和可預測性，通過顯著降低抖動來提供可預測的高性能。

Increasing the predictability of application response times by lowering jitter enables more compute servers to be assigned to a task and can allow more users to access the system, providing a better end-user experience.

Protect, Detect, and Recover

Zero Trust is a security design strategy centered on the belief that organizations, by default, should not automatically trust any request for system access. This includes requests coming from outside, as well as inside its perimeters. Zero Trust demands that every access request be verified before granting access.

零信任是一種安全設計策略，其核心是組織默認不應該自動信任任何系統(tǒng)訪問請求。這包括來自外部的請求，以及來自其邊界內(nèi)的請求。Zero Trust要求在授予訪問權(quán)限之前對每個訪問請求進行驗證。

The 800 Series implements a design philosophy of platform resiliency with 3 attributes compliant with the NIST Cybersecurity Framework, including NIST 800-193 Platform Firmware Resiliency Guidelines: Protect, Detect and Recover. By design, the Hardware Root of Trust in the 800 Series protects the firmware and critical device settings with authentication for every access. Signed firmware updates and the Hardware Root of Trust protects and verifies critical device settings with built-in corruption detection and automated device recovery. Together these features ensure the device safely returns to its originally programmed state.

800系列實現(xiàn)了平臺彈性的設計理念，3個屬性符合NIST網(wǎng)絡安全框架，包括NIST 800-193平臺固件彈性指南:保護、檢測和恢復。通過設計，800系列中的信任硬件根保護固件和關(guān)鍵設備設置，并對每次訪問進行身份驗證。簽名固件更新和硬件根的信任保護和驗證關(guān)鍵設備設置內(nèi)置損壞檢測和自動設備恢復。這些功能共同確保設備安全返回其最初的編程狀態(tài)。
