vRSS 常見問題集vRSS Frequently Asked Questions

本主題中,您會發現一些常常見問題集和解答使用 vRSS。In this topic, you find some commonly asked questions and answers about using vRSS.

實體網路介面卡,讓我搭配 vRSS 需求為何?What are the requirements for the physical network adapters that I use with vRSS?

網路介面卡必須是與虛擬機器佇列 (VMQ) 相容,而且必須有 10 gbps 連結速度或更多。Network adapters must be compatible with Virtual Machine Queue (VMQ) and must have a link speed of 10 Gbps or more.

如需詳細資訊,請參閱計劃 vRSS 使用For more information, see Plan the Use of vRSS.

運作 vRSS hyper\ 執行緒處理器核心?Does vRSS work with hyper-threaded processor cores?

否。No. VRSS 和 VMQ 忽略 hyper\ 執行緒處理器核心。Both vRSS and VMQ ignore hyper-threaded processor cores.

運作 vRSS 的主機虛擬 Nic (vNICs)?Does vRSS work for host virtual NICs (vNICs)?

是。Yes. 使用 -ManagementOS參數,而不是組 VMNetworkAdapter Windows PowerShell 命令上的虛擬機器 (VM) 名稱和啟用 NetAdapterRss主機 vNIC 上。Use the -ManagementOS parameter instead of the virtual machine (VM) name on the Set-VMNetworkAdapter Windows PowerShell command, and Enable-NetAdapterRss on the host vNIC.

若要使用 vRSS 將 VM 需要在有多個邏輯處理器?How many logical processors does a VM need to use vRSS?

虛擬機器必須要能夠使用 vRSS 的兩個或多個邏輯處理器 (LPs)。VMs need two or more logical processors (LPs) to be able to use vRSS.

如需詳細資訊,請參閱計劃 vRSS 使用For more information, see Plan the Use of vRSS.

是 vRSS 與 NIC 小組相容?Is vRSS compatible with NIC Teaming?

是。Yes. 如果您使用 NIC 小組,請務必正確設定 VMQ,若要使用的 NIC 小組的設定。If you are using NIC Teaming, it is important that you properly configure VMQ to work with the NIC Teaming settings. 如需 NIC 小組部署和管理的詳細資訊,請參閱NIC 小組For detailed information about NIC Teaming deployment and management, see NIC Teaming.

vRSS 已啟用,但如何知道是否正在運作?vRSS is enabled, but how do I know if it is working?

您將能夠告知 vRSS 正在運作中您的 VM 開啟工作管理員,並檢視虛擬處理器使用率。You’ll be able to tell vRSS is working by opening the task manager in your VM and viewing the virtual processor utilization. 如果有多個 vm 建立的連線,您可以看到多個核心上面 0%使用率。If there are multiple connections established to the VM, you can see more than one core above 0% utilization.

由於在單一的 TCP 工作階段無法負載平衡跨多個邏輯處理器核心,您的 VM 必須接收多個 TCP 工作階段之前,您可以以觀察 vRSS 正常運作。Because a single TCP session cannot be load balanced across multiple logical processor cores, your VM must be receiving multiple TCP sessions before you can observe whether or not vRSS is working.

如果 VM 會收到多個 TCP 工作階段,但您不會看到一個以上的 LP 核心上方 0%使用率,請確定您已完成所有主題中的計劃 vRSS 利用準備步驟。If the VM is receiving multiple TCP sessions, but you do not see more than one LP core above 0% utilization, ensure that you have completed all of the preparation steps in the topic Plan the Use of vRSS.

我想要在主應用程式,而不是所有的處理器無法使用。I’m looking at the host and not all of the processors are being used. 它看起來就像每一個會略過。It looks like every other one is being skipped.

檢查是否已啟用超執行緒。Check to see if hyper threading is enabled. 設計 VMQ 和 vRSS 略過 hyper\ 執行緒的核心。Both VMQ and vRSS are designed to skip hyper-threaded cores.

RSS 和 vRSS 上有不同的 Windows PowerShell 命令?Are there different Windows PowerShell commands for RSS and vRSS?

\ [是] 和 [否。Yes and no. 雖然在原生主機中的 RSS 和 RSS Vm 中的,您可以使用相同命令,vRSS 也會要求 VMQ,以啟用實體 nic-及 VM 與 vRSS 交換器連接埠上必須啟用。While you use the same commands for both RSS in native hosts and RSS in VMs, vRSS also requires VMQ to be enabled on the physical NIC - and for the VM and vRSS to be enabled on the switch port.
