    Study Notes

    VMware Data Center Virtualization

    • Virtualization is the process of creating a virtual representation of something, like a server, storage device, or network resource.
    • VMware vSphere is a virtualization platform that allows organizations to consolidate their IT resources, reduce costs, and improve efficiency.
    • Key components of vSphere include ESXi (a hypervisor), vCenter Server (a management and control system), and various virtual machine (VM) functionalities.
    • Virtualization offers increased resource utilization by efficiently sharing physical resources.
    • Virtualization allows for quicker deployment and easier management of resources

    vSphere Fundamentals

    • vSphere is a suite of products that enables IT administrators to deploy, manage, and operate virtualized workloads.
    • vCenter Server acts as the central management platform for managing vSphere environments.
    • vCenter Server provides a unified interface for managing virtual machines, storage, networks, and clusters.
    • ESXi is the hypervisor, which is the software that sits on the hardware and creates and manages virtual machines.
    • vSphere has different licensing options depending on the number of CPUs and vCPUs, along with other features such as vSAN, vMotion or vCenter Server, to meet business needs.

    Virtual Machine Management

    • Virtual Machines (VMs) are software-based representations of traditional physical machines.
    • VMware vSphere allows for the creation, customization, and operation of virtual machines.
    • Key tasks in managing VMs include installing, configuring, and monitoring VMs.
    • VMs run within a hypervisor (e.g., ESXi) and are isolated from other VMs, enhancing resource utilization and security.
    • VMware Tools are essential for optimally interfacing with the host operating system.
    • VMware allows for various VM types, ranging from simple development environments to complex and highly specialized applications

    Networking in VMware

    • vSphere uses virtual switches to manage the networking of virtual machines.
    • Virtual switches facilitate communication between VMs as well as with the physical network.
    • Virtual networks can be created and configured separate from physical infrastructure.
    • Network segmentation plays a role in isolation and security.
    • Integration with external networking infrastructure is key to connectivity with on-premises and cloud environments.
    • vCenter Networking and Distributed Virtual Switches (DVS) are crucial for network configuration and management in vSphere environments to support a variety of configurations.

    Storage Management

    • Storage in a vSphere environment is critical for data permanence, storage efficiency, and availability.
    • VMware offers various storage options, including VMFS (VMware File System), NFS, and iSCSI for data storage.
    • Storage capacity requirements are determined based on VM needs.
    • Efficient storage administration and management is key to ensuring availability required in different infrastructure needs for business.
    • VMware vSAN and other storage options for cloud environments enable storage flexibility in scaling up or down according to needs.
    • Data loss prevention measures, such as backups and replication, are crucial.
    • Virtual SAN (vSAN) is a popular storage solution for vSphere environments with efficiency improvement for the storage operations.
    • Storage optimization procedures and best practices can further improve storage efficiency
