In this post I want to show how you can replicate virtual machines from one Data Center, here my on-premise lab environment and running on Microsoft Hyper-V, to another Data Center resp. the Azure Cloud and Azure Hyper-V Server 2022 for nested virtualization. At least the process is always the same, no matter if you are using a Microsoft Hyper-V environment, VMware vSphere environment, Nutanix AHV or KVM, all of them are supported by Veeam Backup & Replication. However it is not possible to replicate virtual machines between different hypervisors, so you just can replicate from Microsoft ..read more

In order to migrate virtual machines between different hypervisor environments, we can use Instant VM Recovery by Veeam Backup and Replication as shown in this post. With Instant Recovery to VMware vSphere, you can immediately recover different workloads (VMs, EC2 instances, physical servers and so on) as VMware vSphere VMs. Instant Recovery to VMware vSphere can be helpful, for example, if you want to migrate your infrastructure from one environment to another, or you want to recover your infrastructure in a matter of minutes but with limited performance.

In order to demonstrate the replication of virtual machines between different data center as shown in my post below, I will create therefore in Azure a new Hyper-V server 2022 (virtual machine) for nested virtualization which then will act as a second data center besides my on-premise lab environment.

In this post we will see step by step how we can set up and deploy a new cluster of two ESXi hosts (2-node cluster). At the end we will also create and adding a datastore cluster to our newly created ESXi host cluster to provide shared storage for. This cluster architecture provides high availability and fault tolerance for virtual machines while minimizing hardware costs. Setting up such a cluster involves configuring shared storage, network connectivity, and cluster-specific settings. By leveraging features like VMware vSphere High Availability (HA) and VMware vSphere Distributed Resource Sc ..read more

In order to provide shared storage to my vSphere lab environment and later creating a vSphere ESXi host cluster, I will configure a new iSCSI virtual disk on my iSCSI Target Server and specify as access servers (so called iSCSI initiator(s)) both of my ESXi hosts. More about the Microsoft iSCSI Target Server you can read in my following post. Set up a Microsoft iSCSI Target Server About how to set up and deploy a VMware ESXi Host Cluster and Datastore Cluster, you can also read my following post.

In this post I want to show how easily you can set up a NFS server in Windows Server 2022 (2012 and later). Further we will see how Windows Server can also connect to UNIX or Linux NFS shares that allows anonymous access by installing the Client for NFS on Windows Server. Network File System (NFS) provides a file sharing solution that lets you transfer files between computers running Windows Server and UNIX or Linux operating systems by using the NFS protocol. NFS in Windows Server includes Server for NFS and Client for NFS. A computer running Windows Server can use Server for NFS to act as ..read more

In this post I will go through the separate steps to set up a SUSE Linux Enterprise Server 15, SLES 15 was published on 13th December 2023. I want to show some basic configurations for Linux operating systems and how they will differ in SUSE Linux Enterprise Server. SUSE Linux Enterprise (SLE) is a Linux-based operating system developed by SUSE. It is available in two editions, suffixed with Server (SLES) for servers and mainframes, and Desktop (SLED) for workstations and desktop computers. SUSE Linux Enterprise products re ..read more

In this post I want to show how you can enable X11 forwarding by using PuTTY and the Xming X Server for Windows. In order to use X11 forwarding, an X11 server needs to be installed on the client (in my case Windows here). Therefore you can use several X11 servers available for Windows, I will use here the Xming X Server which you download under https://sourceforge.net/projects/xming/. X11 forwarding is supported by the SSH protocol that enables users to run graphical applications on a remote server and interact with them by using their local display and I/O devices.
