List of Illustrations

Chapter 1: Introducing VMware vSphere 5.5

Figure 1.1 The VMkernel is the foundation of the virtualization functionality found in VMware ESXi

Figure Figure 1.2 vSphere Virtual SMP allows VMs to be created with more than one : virtual CPU.

Figure 1.3 The vSphere HA feature will restart any VMs that were previously running on an ESXi host that experiences server failure.

Figure 1.4 vSphere FT provides protection against host failures with no downtime experienced by the VMs.

Chapter 2: Planning and Installing VMware ESXi

Figure 2.1 Servers on the HCG come in various sizes and models.

Figure 2.2 The initial ESXi installation routine has options for booting the installer or booting from the local disk.

Figure 2.3 The installer offers options for both local and remote devices; in this case, only a local device was detected.

Figure 2.4 Although local SAS devices are supported, they are listed as remote devices.

Figure 2.5 Checking to see if there are any VMFS datastores on a device can help prevent accidentally overwriting data.

Figure 2.6 You can upgrade or install ESXi as well as choose to preserve or overwrite an existing VMFS datastore.

Figure 2.7 Host information is echoed to the server console when it performs a network boot.

Figure 2.8 This screen provides information about the Auto Deploy server that is registered with vCenter Server.

Figure 2.9 Note the differences in the ESXi boot process when using Auto Deploy versus a traditional installation of ESXi.

Figure 2.10 Editing the host profile to allow Stateless Caching on a local disk

Figure 2.11 You can install the vSphere Client directly from the vCenter Server installation media.

Figure 2.12 Network connectivity won't be established if the ESXi installer links the wrong NIC to the management network.

Figure 2.13 The ESXi home screen provides options for customizing the system and restarting or shutting down the server.

Figure 2.14 In the event the incorrect NIC is assigned to ESXi's management network, you can select a different NIC.

Figure 2.15 Specifying NTP servers allows ESXi to automatically keep time synchronized.

Chapter 3: Installing and Configuring vCenter Server

Figure 3.1 vCenter Server provides a full spectrum of virtualization management functions.

Figure 3.2 The steps taken to issue an authenticated session with the new SSO component.

Figure 3.3 Other applications can extend vCenter Server's core services to provide additional management functionality.

Figure 3.4 vCenter Server acts as a proxy for managing ESXi hosts, but all of the data for vCenter Server is stored in a database.

Figure 3.5 A good disaster recovery plan for vCenter Server should include a quick means of regaining the user interface as well as ensuring that the data is highly available and protected against damage.

Figure 3.6 If vCenter Server is a VM, its virtual disk file can be copied regularly and used as the hard drive for a new VM, effectively providing a point-in-time restore in the event of complete server failure or loss.

Figure 3.7 The SQL Server 2005/2008 database that vCenter Server uses must be owned by the account vCenter Server uses to connect to the database.

Figure 3.8 The VMware vCenter Installer offers options for installing several different components.

Figure 3.9 The vCenter Server installation program will optimize the performance of vCenter Server and its components based on your selection on this screen.

Figure 3.10 You can join an existing vCenter Server instance to a linked mode group.

Figure 3.11 In a linked mode environment, the vSphere Client shows all the vCenter Server instances for which a user has permission.

Figure 3.12 The vCenter Server virtual appliance comes preinstalled with SuSE Linux 11 and vCenter Server.
