VMware vStorage:
Infrastructure services that abstract
storage resources from the complexity of underlying
hardware systems to enable the most efficient utilization of
storage capacity in virtualized environments.
• VMware vStorage Virtual Machine File System (VMFS)
is a high-performance cluster file system that allows
efficient sharing and controls concurrent access to storage
by virtualized servers.

by virtualized servers.
• VMware vStorage Thin Provisioning provides dynamic
allocation of storage capacity, allowing storage purchases
to be deferred until they are really required, reducing
storage spending by up to 50 percent.

VMware vNetwork:
Infrastructure services that enable
optimal administration and management of networking in
virtual environments

• VMware vNetwork Distributed Switch simplifies and
enhances the provisioning, administration and control
of virtual machine networking in VMware vSphere™
environments. It also enables third-party distributed
virtual switches such as the Cisco Nexus 1000v to be used
in VMware vSphere™ environments, providing network
administrators with familiar interfaces to control quality of

Application Services: Built-In Service Level Controls
for Applications
VMware vSphere™ application services provide built-in
controls over application service levels such as availability,
security and scalability, and can be enabled simply and
uniformly for any application running inside VMware virtual
machines

Availability:
Availability services allow IT to provide
applications with varying levels of high availability
depending on their priority and need, without the need for
complex redundant hardware or clustering software.
