VMware Infrastructure

VMware Infrastructure

Legacy x86 computers are designed merely for running a single operating system or application program. Therefore, most of these computers are under-utilized. To address the under-utilization, virtualization technologies are adopted, enabling an x86 physical machine to host multiple virtual machines (VMs) and allowing the multiple VMs to run different operating systems and applications. That is, virtualization allows resources on this physical machine to be shared among multiple environments, thereby improving x86 hardware utilization.

VMware virtualization technology (VMware Infrastructure) adds a condensed software layer on the computer hardware or in the host operating system. This software layer includes a VM monitor utility that allocates hardware resources in a dynamic and transparent way. Each operating system or application can access desired resources anytime as required.

As an outstanding software solution for x86 virtualization, VMware Infrastructure enables users to manage their virtualized environments in an effective and easy manner. As Figure 2-1 shows, a typical VMware Infrastructure datacenter consists of basic physical building blocks such as x86 computing servers, storage networks and arrays, IP networks, a management server, and desktop clients.

Figure 2-1 VMware Infrastructure datacenter

In a VMware Infrastructure storage architecture (as shown in Figure 2-2):

  • A Virtual Machine File System (VMFS) volume contains one or more LUNs which belong to one or more storage arrays.
  • Multiple ESX servers share one VMFS volume; virtual disks are created on the VMFS volume for use by VMs.

VMware uses VMFS to centrally manage storage systems. VMFS is a shared cluster file system designed for VMs. This file system employs a distributed locking function to enable independent access to disks, ensuring that a VM is accessed by one physical host at a time. Raw Device Mapping (RDM) is a special file acting as the agent for raw devices on a VMFS volume.
