What vSphere Does
Powerful Server Virtualization
Virtualize your x86 server resources and aggregate them into logical pools for allocation of multiple workloads.
Get network services optimized for the virtual environment, along with simplified administration and management.
Reduce the complexity of back-end storage systems and enable the most efficient storage utilization in cloud infrastructures.
Protect your data and applications with the industrys most secure bare-metal? server virtualization platform.
Maximize uptime across your cloud infrastructure, reducing unplanned downtime and eliminating planned downtime for server and storage maintenance.
Lower operating expenditures and minimize errors by streamlining routine tasks with vSphere's accurate and repeatable solutions.
A virtual machine is a software construct controlled by the VMware vSphere hypervisor (known as the VMkernel?). Virtual machines are the basic computing components of your virtual infrastructure. In lieu of physical systems, they are software constructs that create the basis of your agile data center. All virtual machine configuration information, state information and data are encapsulated in a set of discrete files stored on a datastore. This encapsulation makes virtual machines portable and easily backed up or cloned.
Virtual Machine Components
Each virtual machine has virtual hardware that appears as physical hardware to the installed guest operating system and its applications. In addition to the operating system, each virtual machine typically also has VMware Tools and virtual resources and hardware that you manage similarly to a physical computer. VMware Tools enhances the performance of the virtual machines guest OS and improves the management of the virtual machine, giving you more control over the interface. All virtual machines have a hardware version, which indicates the virtual hardware features that the virtual machine supports.
A virtual machine is configured with at least one virtual CPU (VCPU) and as many as 64 VCPUs, if you use vSphere's virtual symmetric multiprocessor feature called VMware Virtual SMP. When a VCPU needs to run, the VMkernel maps the VCPU to an available hardware execution context (HEC). A HEC is a processors capability to schedule one thread of execution, which corresponds to a CPU core or a hyperthread (if the CPU supports hyperthreading). Hyperthread or multicore CPUs provide two or more HECs on which VCPUs can be scheduled to run.
When you combine multiple virtual machines on one physical server, you can more efficiently use the large amounts of memory on that physical server, which ultimately reduces data center capital and operating costs. vSphere uses several features to support the efficient use of RAM and higher consolidation rations, including transparent page sharing, guest memory reclaim, and memory compression.
Shares and Limits
When several virtual machines are running together on a single host (or in a cluster), vSphere uses shares and limits to make sure that each virtual machine has enough resources, including CPU, memory, network and storage. Shares guarantee that a virtual machine is given a certain percentage of a resource, according to the defaults in place. Limits provide a hard ceiling for resource allocation, depending on the configuration of a virtual machine.
