![]() ![]() ![]() Note: FreeNAS is a universal and flexible FreeBSD-based operating system that you can install on a computer to use it as NAS. Of course, setting up iSCSI on vendor hardware of your choice or software iSCSI can be different depending on the vendor, so always follow the methods defined for each. For iSCSI storage in a lab environment, in this example, we are using FreeNAS to create iSCSI targets and present these to our Hyper-V cluster. Hyper-V cluster storage is a crucial point for building a cluster. This would need to be thought through in advance. VLANs are also a consideration here, as you will most likely want to align your subnets with VLANs provisioned. With the above networks in mind, we assign IP Addresses to each server in our desired subnet ranges. However, you would want to team your adapters in production to avoid having a single point of failure in any one network. Both lab hosts are not doing any NIC teaming for simplicity sake. For the lab network in this scenario, four network adapters have been configured for each host. Proper environment planning mitigates many risks in the future. This ensures that everything is standardized between the hosts, including patch levels, networks, etc. As a best practice, we want all our potential cluster nodes to be configured identically except for computer names and IP addresses. ![]() You may need to restart Windows to complete the installation of updates. Installing updates on Hyper-V hosts improves the security of our system. We need to update any prospective Hyper-V cluster nodes to the latest patch level available according to the Hyper-V clustering best practices. The configurations for the second server H2 are similar. Server configurations are displayed in the screenshots below for the first server H1. Note that starting with Windows Server 2016, joining a domain is no longer a prerequisite. Both servers have been named and joined to the lab domain. Network planning, in particular, is crucial in a Windows cluster as it allows for proper cluster communication as well as communication with shared storage. This involves much of the same steps of preparing any Windows server – naming, network configuration, patching, etc. Initial configuration of the environmentīefore thinking about the Hyper-V hosts as a cluster, we must perform our initial configuration of the hosts. It is technically possible to use Windows Server with Desktop Experience to configure Hyper-V failover clustering. Note: For the administration and configuration of Windows Server 2016 Server Core, we use PowerShell. You can also use the newer Windows Server versions, such as Windows Server 2019 for Hyper-V cluster setup. The increased difficulty of administration with Server Core is offset by the benefits of efficiency and security. Using the Windows Server 2016 Server Core installation eliminates a lot of unnecessary components and reduces the footprint. In this setup, we are using two Windows Server 2016 Server Core installations to minimize moving parts and to improve security. Then we need to perform a basic configuration of the environment, including all hosts, to prepare them for Hyper-V cluster setup. To prepare hosts for failover clustering, we should select an operating system to install on all the hosts that will be used in a particular cluster.
