Книга: Mastering VMware® Infrastructure3

The Bottom Line

The Bottom Line

Understand the architecture of ESXi. ESXi presents a radical change not just to the virtualization world but to the system manufacturers that want to be part of virtualization evolution. By removing the local management component, the Service Console, ESXi presents a thin yet highly functional hypervisor on which virtual machines can run. But don't mistake thin for meaning not as feature rich. ESXi supports all the same enterprise features of VMotion, DRS, and HA that have made VMware ESX the number-one choice for the foundation of virtualization platforms around the world.

Master It You manage a datacenter that experiences rapid growth. You need to identify a way to introduce new hardware resources into the virtual infrastructure with minimal administrative effort and maximum security.

Deploy ESXi Installable. ESXi Installable provides existing VI3 licensees with the ability to shift their infrastructures to the new thin hypervisor architecture. The installation files can be downloaded as part of the existing license agreement without any penalty or additional cost. ESXi Installable installs onto local disk drives.

Master It You manage a datacenter with five existing ESX Server 3.5 hosts. You wish to restructure the datacenter to use the thin hypervisor architecture of ESXi.

Deploy ESXi Embedded. ESXi Embedded, like ESXi Installable, is a thin hypervisor architecture with no reliance on a console operating system; however, the hypervisor runs from an embedded storage module on the host. System manufacturers like Dell offer next-generation products that include internal storage functionality for running ESXi Embedded.

Master It You want to construct a virtual infrastructure on physical servers without local storage devices. You want the CPU and memory of each server to be allocated to a VMware cluster for supporting HA and DRS.

Manage ESXi. Managing ESXi can be done using the console of the system, the VI Client connected directly to the server, the VI Client connected to VirtualCenter, or from a command line using the remote CLI tools. The remote CLI tools can be deployed on a Windows host, Linux host, or from within a downloadable virtual appliance. All are available from the VMware website.

Master It You have deployed four servers running ESXi. You need to configure them into a cluster that supports DRS and HA.

Master It You have 30 ESXi hosts to which you need to add a new virtual switch. Your administrative desktop runs Windows XP Professional.
