vRSS 常見問題集vRSS Frequently Asked Questions

以下是一些常見問題的問與答使用 vRSS。Following are some commonly asked questions and answers about using vRSS.

使用 vRSS 實體網路介面卡的需求為何?What are the requirements for the physical network adapters that I use with vRSS?

網路介面卡必須一樣佇列 (VMQ) 與相容,必須 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,請查看計劃 vRSS 使用For more information, see Plan the Use of vRSS.

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

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

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

[是]。Yes. 使用-ManagementOS參數,而不是在一樣 (VM) 名稱VMNetworkAdapter 設定為Windows PowerShell 命令,並讓-NetAdapterRss上主機但 vNIC。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.

使用 vRSS 將 VM 需要在多少邏輯處理器?How many logical processors does a VM need to use vRSS?

Vm 需要兩個或更多,才能使用 vRSS 邏輯處理器 (LPs)。VMs need two or more logical processors (LPs) to be able to use vRSS.

是 vRSS NIC 小組與相容?Is vRSS compatible with NIC Teaming?

[是]。Yes. 如果您使用 NIC 小組,請務必正確設定 VMQ NIC 的聯合設定的運作。If you are using NIC Teaming, it is important that you properly configure VMQ to work with the NIC Teaming settings. 適用於 NIC 小組部署與管理的詳細資訊,請查看NIC 小組For detailed information about NIC Teaming deployment and management, see NIC Teaming.

vRSS 支援,但如何知道它是否正常運作?vRSS is enabled, but how do I know if it is working?

您就可以告訴 vRSS 正在打開您 VM 中的工作管理員或檢視 virtual 處理器使用量。You’ll be able to tell vRSS is working by opening the task manager in your VM and viewing the virtual processor utilization. 如果有多個連接建立 vm 中,您可以看到多個核心使用量 0%以上。If there are multiple connections established to the VM, you can see more than one core above 0% utilization.

單一 TCP 工作階段無法負載平衡跨多個邏輯處理器核心,因為您 VM 必須接收 TCP 多個工作階段之前,您可以看到 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 接收多個 TCP 工作階段,但您看不到 0%使用量上方的多個 LP 核心,確定您已完成準備步驟主題中的所有計劃 vRSS 使用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.

我想要在主機,並使用並非所有的處理器。I’m looking at the host and not all of the processors are being used. 您似乎已略過每一個。It looks like every other one is being skipped.

若要查看是否支援超執行緒檢查。Check to see if hyper threading is enabled. VMQ 和 vRSS 專為略過 hyper\ 執行緒核心。Both VMQ and vRSS are designed to skip hyper-threaded cores.

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

[是] 並無。Yes and no. 雖然您可以使用相同的命令中原生主機 RSS 和 RSS,在 Vm 中的,vRSS 也需要 VMQ 可實體而-和 VM 和 vRSS 上切換連接埠。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.
