Storage Spaces Direct uses local- attached drives on servers to create highly available storage at a minimal cost of traditional storage devices (SAN or NAS). Storage Spaces Direct uses regular hard drives that are connected to a single node of the failover cluster, and these disks can be used as storage for the cluster. To […]
To create a storage space on a Windows client, perform the following: FIGURE 13.24 Create A New Pool And Storage Space option To create a storage space on a stand- alone server, you’ll follow three steps: ■ Step 1: Create a storage pool: Group available physical disks into one or more storage pools. Storage […]
Table 13.3 contains just some of the PowerShell commands that you can use to configure and manage Windows Server 2022 clustering. TABLE 13.3 Windows Server 2022 clustering PowerShell commands Add- ClusterDisk This command allows you to add a new disk to a failover cluster. The disk’s LUN must be visible to all cluster nodes. Add- […]
Microsoft’s object storage solution for the cloud is called Azure Blob Storage. Blob Storage is designed for storing large amounts of unstructured data, which is data that doesn’t adhere to any particular data model or definition, such as text or binary data. Blob Storage is used for these purposes: ■ Serving images or documents […]
Microsoft Cloud Witness is a high- availability feature for failover clusters that uses storage in Azure so that clusters will continue to work if there is an onsite outage. It is a type of failover cluster quorum witness that uses Azure. I briefly discussed Cloud Witness earlier in the chapter, but now I want to […]
A cluster set is a group of multiple failover clusters that are clustered together. You can increase the number of server nodes in a single software- defined datacenter (SDDC) cloud by orders of magnitude by configuring cluster sets. Benefits of Cluster Sets There are a number of benefits of cluster sets, such as the following: […]
Many features are included in the Windows Server 2022 release for clustering. It is a rich feature set of high availability with greatly improved flexibility based on the needs of IT organizations. The new features relate to quorum behavior, virtual machine hosting, Active Directory–detached clusters, and a new dashboard. Windows PowerShell Cmdlets for Failover Clusters […]
Windows Server 2022 has options that let fine- tune the failover process to meet the needs of your business. I’ll cover these options in the next few sections. Failover occurs when a clustered application or service moves from one node to another. The process can be triggered automatically because of a failure or server maintenance […]
After you have successfully validated a configuration and the cluster hardware is in a supportable state, you can create a cluster. The process for creating a cluster is straightforward and similar to running the Validate A Configuration Wizard. To create a cluster with two servers, follow the instructions in Exercise 13.4. EXERCISE 13.4 Creating a […]
The Validate A Configuration Wizard, shown in Figure 13.15, is simple to use. You should run it after the Failover Clustering feature has been installed on each of the cluster nodes, and it can be run as many times as you need. FIGURE 13.15 The Validate A Configuration Wizard If you already have a cluster […]
