[Hardware specifications](https://learn.microsoft.com/en-us/azure/virtual-machines/<#hardware-specifications>)\n 2.

[Next steps](https://learn.microsoft.com/en-us/azure/virtual-machines/<#next-steps>)\n\n**Applies to:** ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets\nMaximizing HPC application performance on Intel Xeon Scalable Processors requires a thoughtful approach to process placement on this new architecture. Here, we outline our implementation of it on Azure HC-series VMs for HPC applications. We'll use the term “pNUMA” to refer to a physical NUMA domain, and “vNUMA” to refer to a virtualized NUMA domain. Similarly, we'll use the term “pCore” to refer to physical CPU cores, and “vCore” to refer to virtualized CPU cores.\nPhysically, an [HC-series](https://learn.microsoft.com/en-us/azure/virtual-machines/<hc-series>) server is 2 * 24-core Intel Xeon Platinum 8168 CPUs for a total of 48 physical cores. Each CPU is a single pNUMA domain, and has unified access to six channels of DRAM. Intel Xeon Platinum CPUs feature a 4x larger L2 cache than in prior generations (256 KB/core -> 1 MB/core), while also reducing the L3 cache compared to prior Intel CPUs (2.5 MB/core -> 1.375 MB/core).\nThe above topology carries over to the HC-series hypervisor configuration as well. To provide room for the Azure hypervisor to operate without interfering with the VM, we reserve pCores 0-1 and 24-25 (that is, the first 2 pCores on each socket). We then assign pNUMA domains all remaining cores to the VM. Thus, the VM will see:\n`(2 vNUMA domains) * (22 cores/vNUMA) = 44` cores per VM\nThe VM has no knowledge that pCores 0-1 and 24-25 weren't given to it. Thus, it exposes each vNUMA as if it natively had 22 cores.\nIntel Xeon Platinum, Gold, and Silver CPUs also introduce an on-die 2D mesh network for communication within and external to the CPU socket. We strongly recommend process pinning for optimal performance and consistency. Process pinning will work on HC-series VMs because the underlying silicon is exposed as-is to the guest VM.\nThe following diagram shows the segregation of cores reserved for Azure Hypervisor and the HC-series VM.\n\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#hardware-specifications>)" } ]

[ { "from": "system", "value": "You are an Azure AI assistant, trained to help users understand and work with Azure services and documentation. You have deep knowledge of Azure's cloud platform, particularly about: . Provide clear, accurate, and helpful responses based on official Azure documentation." }, { "from": "human", "value": "Can you explain Create a Service Fabric cluster in Azure?" }, { "from": "gpt", "value": "The following steps create the necessary resources required to deploy your application to a Service Fabric cluster. Additionally, resources necessary to monitor the health of your solution using the ELK (Elasticsearch, Logstash, Kibana) stack are set up. Specifically, [Event Hubs](https://learn.microsoft.com/en-us/azure/service-fabric/<https:/azure.microsoft.com/services/event-hubs/>) is used as a sink for logs from Service Fabric. It is configured to send logs from the Service Fabric cluster to your Logstash instance.\n 1. Open a terminal and download the following package that contains necessary helper scripts and the templates to create the resources in Azure\nBash Copy\n```\ngit clone https://github.com/Azure-Samples/service-fabric-java-quickstart.git\n\n```\n\n 2. Sign in to your Azure account\nAzure CLI Copy\n```\naz login\n\n```\n\n 3. Set your Azure subscription that you want to use to create the resources\nAzure CLI Copy\n```\naz account set --subscription [SUBSCRIPTION-ID]\n\n```\n\n 4. From the _service-fabric-java-quickstart/AzureCluster_ folder, run the following command to create a cluster certificate in Key Vault. This certificate is used to secure your Service Fabric cluster. Provide the region (must be the same as your Service Fabric cluster), key vault resource group name, key vault name, certificate password, and cluster DNS name.\nBash Copy\n```\n./new-service-fabric-cluster-certificate.sh [REGION] [KEY-VAULT-RESOURCE-GROUP] [KEY-VAULT-NAME] [CERTIFICATE-PASSWORD] [CLUSTER-DNS-NAME-FOR-CERTIFICATE]\nExample: ./new-service-fabric-cluster-certificate.sh 'westus' 'testkeyvaultrg' 'testkeyvault' '<password>' 'testservicefabric.westus.cloudapp.azure.com'\n\n```\n\nThe preceding command returns the following information that should be noted for use later.\nOutput Copy\n```\nSource Vault Resource Id: /subscriptions/<subscription_id>/resourceGroups/testkeyvaultrg/providers/Microsoft.KeyVault/vaults/<name>\nCertificate URL: https://<name>.vault.azure.net/secrets/<cluster-dns-name-for-certificate>/<guid>\nCertificate Thumbprint: <THUMBPRINT>\n\n```\n\n 5. Create a resource group for the storage account that stores your logs\nAzure CLI Copy\n```\naz group create --location [REGION] --name [RESOURCE-GROUP-NAME]\nExample: az group create --location westus --name teststorageaccountrg\n\n```\n\n 6. Create a storage account which will be used to store the logs that will be produced\nAzure CLI Copy\n```\naz storage account create -g [RESOURCE-GROUP-NAME] -l [REGION] --name [STORAGE-ACCOUNT-NAME] --kind Storage\nExample: az storage account create -g teststorageaccountrg -l westus --name teststorageaccount --kind Storage\n\n```\n\n 7. Access the [Azure portal](https://learn.microsoft.com/en-us/azure/service-fabric/<https:/portal.azure.com>) and navigate to the **Shared Access Signature** tab for your Storage account. Generate the SAS token as follows.\n\n 8. Copy the account SAS URL and set it aside for use when creating your Service Fabric cluster. It resembles the following URL:\nOutput Copy\n```\n?sv=2017-04-17&ss=bfqt&srt=sco&sp=rwdlacup&se=2018-01-31T03:24:04Z&st=2018-01-30T19:24:04Z&spr=https,http&sig=IrkO1bVQCHcaKaTiJ5gilLSC5Wxtghu%2FJAeeY5HR%2BPU%3D\n\n```\n\n 9. Create a resource group that contains the Event Hub resources. Event Hubs is used to send messages from Service Fabric to the server running the ELK resources.\nAzure CLI Copy\n```\naz group create --location [REGION] --name [RESOURCE-GROUP-NAME]\nExample: az group create --location westus --name testeventhubsrg\n\n```\n\n 10. Create an Event Hubs resource using the following command. Follow the prompts to enter details for the namespaceName, eventHubName, consumerGroupName, sendAuthorizationRule, and receiveAuthorizationRule.\nAzure CLI Copy\n```\naz deployment group create -g [RESOURCE-GROUP-NAME] --template-file eventhubsdeploy.json\nExample:\naz deployment group create -g testeventhubsrg --template-file eventhubsdeploy.json\nPlease provide string value for 'namespaceName' (? for help): testeventhubnamespace\nPlease provide string value for 'eventHubName' (? for help): testeventhub\nPlease provide string value for 'consumerGroupName' (? for help): testeventhubconsumergroup\nPlease provide string value for 'sendAuthorizationRuleName' (? for help): sender\nPlease provide string value for 'receiveAuthorizationRuleName' (? for help): receiver\n\n```\n\nCopy the contents of the **output** field in the JSON output of the preceding command. The sender information is used when the Service Fabric cluster is created. The receiver name and key should be saved for use in the next tutorial when the Logstash service is configured to receive messages from Event Hub. The following blob is an example JSON output:\nJSON Copy\n```\n\"outputs\": {\n \"receiver Key\": {\n \"type\": \"String\",\n \"value\": \"[KEY]\"\n },\n \"receiver Name\": {\n \"type\": \"String\",\n \"value\": \"receiver\"\n },\n \"sender Key\": {\n \"type\": \"String\",\n \"value\": \"[KEY]\"\n },\n \"sender Name\": {\n \"type\": \"String\",\n \"value\": \"sender\"\n }\n}\n\n```\n\n 11. Run the _eventhubssastoken.py_ script to generate the SAS url for the EventHubs resource you created. This SAS URL is used by the Service Fabric cluster to send logs to Event Hubs. As a result, the **sender** policy is used to generate the URL. The script returns the SAS URL for the Event Hubs resource that is used in the following step:\nPython Copy\n```\npython3 eventhubssastoken.py 'testeventhubs' 'testeventhubs' 'sender' '[PRIMARY-KEY]'\n\n```\n\nCopy the value of the **sr** field in the JSON returned. The **sr** field value is the SAS token for EventHubs. The following URL is an example of the **sr** field:\nOutput Copy\n```\nhttps%3A%2F%testeventhub.servicebus.windows.net%testeventhub&sig=7AlFYnbvEm%2Bat8ALi54JqHU4i6imoFxkjKHS0zI8z8I%3D&se=1517354876&skn=sender\n\n```\n\nYour SAS URL for the EventHubs follows the structure: `https://<namespacename>.servicebus.windows.net/<eventhubsname>?sr=<sastoken>`. For example, `https://testeventhubnamespace.servicebus.windows.net/testeventhub?sr=https%3A%2F%testeventhub.servicebus.windows.net%testeventhub&sig=7AlFYnbvEm%2Bat8ALi54JqHU4i6imoFxkjKHS0zI8z8I%3D&se=1517354876&skn=sender`\n 12. Open the _sfdeploy.parameters.json_ file and replace the following contents from the preceding steps. [SAS-URL-STORAGE-ACCOUNT] was noted in step 8. [SAS-URL-EVENT-HUBS] was noted in step 11.\nJSON Copy\n```\n\"applicationDiagnosticsStorageAccountName\": {\n \"value\": \"teststorageaccount\"\n},\n\"applicationDiagnosticsStorageAccountSasToken\": {\n \"value\": \"[SAS-URL-STORAGE-ACCOUNT]\"\n},\n\"loggingEventHubSAS\": {\n \"value\": \"[SAS-URL-EVENT-HUBS]\"\n}\n\n```\n\n 13. Opens **sfdeploy.parameters.json**. Change the following parameters and then save the file.\n * **clusterName**. Use only lower-case letters and numerals.\n * **adminUserName** (to a value other than blank)\n * **adminPassword** (to a value other than blank)\n 14. Run the following command to create your Service Fabric cluster\nAzure CLI Copy\n```\naz sf cluster create --location 'westus' --resource-group 'testlinux' --template-file sfdeploy.json --parameter-file sfdeploy.parameters.json --secret-identifier <certificate_url_from_step4>\n\n```\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#deploy-your-application-to-the-cluster>)" } ]

Before deploying your application, you need to add the following snippet to the _Voting/VotingApplication/ApplicationManifest.xml_ file. The **X509FindValue** field is the thumbprint returned from Step 4 of the **Create a Service Fabric cluster in Azure** section. This snippet is nested under the **ApplicationManifest** field (the root field).\nXML Copy\n```\n<Certificates>\n <SecretsCertificate X509FindType=\"FindByThumbprint\" X509FindValue=\"[CERTIFICATE-THUMBPRINT]\" />\n</Certificates>\n\n```\n\n 2. To deploy your application to this cluster, you must use SFCTL to establish a connection to the cluster. SFCTL requires a PEM file with both the public and private key to connect to the cluster. Run the following command to produce a PEM file with both the public and private key.\nBash Copy\n```\nopenssl pkcs12 -in <clustername>.<region>.cloudapp.azure.com.pfx -out sfctlconnection.pem -nodes -passin pass:<password>\n\n```\n\n 3. Run the following command to connect to the cluster.\nBash Copy\n```\nsfctl cluster select --endpoint https://<clustername>.<region>.cloudapp.azure.com:19080 --pem sfctlconnection.pem --no-verify\n\n```\n\n 4. To deploy your application, navigate to the _Voting/Scripts_ folder and run the **install.sh** script.\nBash Copy\n```\n./install.sh\n\n```\n\n 5. To access Service Fabric Explorer, open your favorite browser and type in `https://testlinuxcluster.westus.cloudapp.azure.com:19080`. Choose the certificate from the certificate store that you want to use to connect to this endpoint. If you are using a Linux machine, the certificates that were generated by the _new-service-fabric-cluster-certificate.sh_ script has to be imported into Chrome to view Service Fabric Explorer. If you are using a Mac, you have to install the PFX file into your Keychain. You notice your application has been installed on the cluster.\n\n 6. To access your application, type in `https://testlinuxcluster.westus.cloudapp.azure.com:8080`\n\n 7. To uninstall your application from the cluster, run the _uninstall.sh_ script in the **Scripts** folder\nBash Copy\n```\n./uninstall.sh\n\n```\n\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#next-steps>)" } ]

[Next steps](https://learn.microsoft.com/en-us/azure/virtual-machines/<#next-steps>)\n\n**Applies to:** ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets\nNote\nThis article focuses on how to change performance tiers. To learn how to change the performance of disks that don't use performance tiers, like Ultra Disks or Premium SSD v2, see either [Adjust the performance of an ultra disk](https://learn.microsoft.com/en-us/azure/virtual-machines/<disks-enable-ultra-ssd#adjust-the-performance-of-an-ultra-disk>) or [Adjust disk performance of a Premium SSD v2](https://learn.microsoft.com/en-us/azure/virtual-machines/<disks-deploy-premium-v2#adjust-disk-performance>)\nThe performance of Premium solid-state drives (SSD) is set when you create your disk, in the form of their performance tier. When you set the provisioned size of your disk, a performance tier is automatically selected. The performance tier determines the IOPS and throughput your managed disk has. For Premium SSD disks only, the performance tier can be changed at deployment or afterwards, without changing the size of the disk, and without downtime.\nChanging the performance tier allows you to prepare for and meet higher demand without using your disk's bursting capability. It can be more cost-effective to change your performance tier rather than rely on bursting, depending on how long the additional performance is necessary. This is ideal for events that temporarily require a consistently higher level of performance, like holiday shopping, performance testing, or running a training environment. To handle these events, you can switch a disk to a higher performance tier without downtime, for as long as you need the additional performance. You can then return to the original tier without downtime when the additional performance is no longer necessary.\nTo learn more about how the performance of a disk works with the performance of a virtual machine, see [Virtual machine and disk performance](https://learn.microsoft.com/en-us/azure/virtual-machines/<disks-performance>).\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#restrictions>)" } ]

For example, if you provision a P10 disk (128 GiB), your baseline performance tier is set as P10 (500 IOPS and 100 MBps). You'll be billed at the P10 rate. You can upgrade the tier to match the performance of P50 (7,500 IOPS and 250 MBps) without increasing the disk size. During the time of the upgrade, you'll be billed at the P50 rate. When you no longer need the higher performance, you can return to the P10 tier.

[Troubleshooting](https://learn.microsoft.com/en-us/azure/service-fabric/<#troubleshooting>)\n 5. [Next Steps](https://learn.microsoft.com/en-us/azure/service-fabric/<#next-steps>)\n\nEach node type in a Service Fabric managed cluster is backed by a virtual machine scale set. To allow managed identities to be used with a managed cluster node type, a property `vmManagedIdentity` has been added to node type definitions containing a list of identities that may be used, `userAssignedIdentities`. Functionality mirrors how managed identities can be used in non-managed clusters, such as using a managed identity with the [Azure Key Vault virtual machine scale set extension](https://learn.microsoft.com/en-us/azure/service-fabric/<../virtual-machines/extensions/key-vault-windows>).\nFor an example of a Service Fabric managed cluster deployment that makes use of managed identity on a node type, see [these templates](https://learn.microsoft.com/en-us/azure/service-fabric/<https:/github.com/Azure-Samples/service-fabric-cluster-templates/tree/master/SF-Managed-Standard-SKU-1-NT-MI>). The example has two templates:\n 1. **Managed identity and role assignment** : Template to create the managed identity and the role assignment to allow Service Fabric RP to assign the identity to the managed cluster's virtual machine scale set. This should be deployed only once before using the managed identity on the node type resource.\n 2. **Managed cluster and node type** : Template for the service fabric managed cluster and node type resources using the managed identity created before.\n\nNote\nOnly user-assigned identities are currently supported for this feature.\nNote\nSee [Configure and use applications with managed identity on a Service Fabric managed cluster](https://learn.microsoft.com/en-us/azure/service-fabric/<how-to-managed-cluster-application-managed-identity>) for application configuration.\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#prerequisites>)" } ]

This includes Intel, AMD, and ARM. Specific details for these silicon-based vulnerabilities can be found in the following security advisories and CVEs:\n * [ADV180002 - Guidance to mitigate speculative execution side-channel vulnerabilities](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV180002>)\n * [ADV180012 - Microsoft Guidance for Speculative Store Bypass](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV180012>)\n * [ADV180013 - Microsoft Guidance for Rogue System Register Read](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV180013>)\n * [ADV180016 - Microsoft Guidance for Lazy FP State Restore](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV180016>)\n * [ADV180018 - Microsoft Guidance to mitigate L1TF variant](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV180018>)\n * [ADV190013 - Microsoft Guidance to mitigate Microarchitectural Data Sampling vulnerabilities](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV190013>)\n * [ADV220002 - Microsoft Guidance on Intel Processor MMIO Stale Data Vulnerabilities](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/ADV220002>)\n * [CVE-2022-23816 - AMD CPU Branch Type Confusion](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/CVE-2022-23816>)\n * [CVE-2022-21123 - AMD CPU Branch Type Confusion](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/msrc.microsoft.com/update-guide/vulnerability/CVE-2022-23825>)\n\nThe disclosure of these CPU vulnerabilities has resulted in questions from customers seeking more clarity.\nMicrosoft has deployed mitigations across all our cloud services. The infrastructure that runs Azure and isolates customer workloads from each other is protected. This means that a potential attacker using the same infrastructure can't attack your application using these vulnerabilities.\nAzure is using [memory preserving maintenance](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/azure/virtual-machines/maintenance-and-updates?bc=%2fazure%2fvirtual-machines%2fwindows%2fbreadcrumb%2ftoc.json%252c%2fazure%2fvirtual-machines%2fwindows%2fbreadcrumb%2ftoc.json&toc=%2fazure%2fvirtual-machines%2fwindows%2ftoc.json%253ftoc%253d%2fazure%2fvirtual-machines%2fwindows%2ftoc.json#maintenance-that-doesnt-require-a-reboot>) whenever possible, to minimize customer impact and eliminate the need for reboots. Azure will continue utilizing these methods when making systemwide updates to the host and protect our customers.\nMore information about how security is integrated into every aspect of Azure is available on the [Azure Security Documentation](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/azure/security/index>) site.\nNote\nSince this document was first published, multiple variants of this vulnerability class have been disclosed. Microsoft continues to be heavily invested in protecting our customers and providing guidance. This page will be updated as we continue to release further fixes.\n**Customers that are running untrusted code within their VM** need to take action to protect against these vulnerabilities by reading below for more guidance on all vulnerabilities.\nOther customers should evaluate these vulnerabilities from a Defense in Depth perspective and consider the security and performance implications of their chosen configuration.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#keeping-your-operating-systems-up-to-date>)" } ]

While numerous mitigations are enabled by default, the extra features described here must be enabled manually and may cause a performance impact.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#option-1>)\n#### Option 1\n**Step 1:** Follow the instructions in [KB4072698](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/support.microsoft.com/help/4072698/windows-server-guidance-to-protect-against-the-speculative-execution>) to verify protections are enabled using the [SpeculationControl](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/aka.ms/SpeculationControlPS>) PowerShell module.\nNote\nIf you previously downloaded this module, you will need to install the newest version.\nTo validate enabled protections against these vulnerabilities, see [Understanding Get-SpeculationControlSettings PowerShell script output](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/support.microsoft.com/topic/understanding-get-speculationcontrolsettings-powershell-script-output-fd70a80a-a63f-e539-cda5-5be4c9e67c04>).\nIf protections aren't enabled, please [contact Azure Support](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/aka.ms/microcodeenablementrequest-supporttechnical>) to enable additional controls on your Azure VM.\n**Step 2:** To enable Kernel Virtual Address Shadowing (KVAS) and Branch Target Injection (BTI) OS support, follow the instructions in [KB4072698](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/support.microsoft.com/help/4072698/windows-server-guidance-to-protect-against-the-speculative-execution>) to enable protections using the `Session Manager` registry keys. A reboot is required.\n**Step 3:** For deployments that are using [nested virtualization](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/virtualization/hyper-v-on-windows/user-guide/nested-virtualization>) (D3 and E3 only): These instructions apply inside the VM you're using as a Hyper-V host.\n 1. Follow the instructions in [KB4072698](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/support.microsoft.com/help/4072698/windows-server-guidance-to-protect-against-the-speculative-execution>) to enable protections using the `MinVmVersionForCpuBasedMitigations` registry keys.\n 2. Set the hypervisor scheduler type to `Core` by following the instructions [here](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/windows-server/virtualization/hyper-v/manage/manage-hyper-v-scheduler-types>).\n\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#option-2>)\n#### Option 2\n**Disable hyper-threading on the VM** - Customers running untrusted code on a hyper-threaded VM might choose to disable hyper-threading or move to a non-hyper-threaded VM size. Reference [this doc](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/azure/virtual-machines/acu>) for a list of hyper-threaded VM sizes (where ratio of vCPU to Core is 2:1). To check if your VM has hyper-threading enabled, refer to the below script using the Windows command line from within the VM.\nType `wmic` to enter the interactive interface. Then type the following command to view the amount of physical and logical processors on the VM.\nCopy\n```\nCPU Get NumberOfCores,NumberOfLogicalProcessors /Format:List\n\n```\n\nIf the number of logical processors is greater than physical processors (cores), then hyper-threading is enabled. If you're running a hyper-threaded VM, [contact Azure Support](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/aka.ms/MicrocodeEnablementRequest-SupportTechnical>) to get hyper-threading disabled. Once hyper-threading is disabled, support will require a full VM reboot. Refer to [Core count](https://learn.microsoft.com/en-us/azure/virtual-machines/<#core-count>) to understand why your VM core count decreased.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#option-3>)" } ]
