High Availability

VMware software makes it simpler and less expensive to provide higher levels of availability for important applications. With VMware virtual infrastructure, organisations can easily increase the baseline level of availability provided for all applications as well as provide higher levels of availability more easily and cost effectively. With VMware virtual infrastructure, customers have been able to:

• Provide higher availability independent of hardware, operating system, and applications
• Reduce planned maintenance downtime to ZERO for common maintenance operations
• Provide automatic restart of systems in the case of server failure

Slash Planned Downtime

VMware Infrastructure makes it possible for organisations to dramatically reduce planned downtime. Because workloads in a VMware Infrastructure environment can be dynamically moved to different physical servers without downtime or service interruption, server maintenance can be performed without requiring application and service downtime. With VMware Infrastructure organisations can:

• Eliminate downtime for common maintenance operations
• Eliminate planned maintenance windows
• Perform maintenance at any time without disrupting users and services

Prevent Unplanned Downtime

VMware infrastructure builds important fault tolerance capabilities into datacenter infrastructure. Because they are part of virtual infrastructure, these capabilities are transparent to the operating system and applications running in virtual machines. These features can be easily configured and can be utilised by all of the virtual machines on a physical system, reducing the cost and complexity of providing higher availability. Key fault-tolerance capabilities built into VMware Infrastructure include:

Ensure Rapid Recovery from Outages

VMware software makes possible rapid and automated restart and failover without the cost or complexity of solutions used with physical infrastructure. Virtual machines are hardware-independent and can share physical resources, thus failover can be implemented without requiring dedicated, identical standby hardware and the added complexity of maintaining identical configurations.

For server failures, Vmware High Availability (HA) - a component of Vmware Infrastructure - ensures rapid, automated restart of virtual machines. VMware HA automatically and intelligently restarts affected virtual machines on other production servers. As a part of virtual infrastructure, VMware HA can be easily configured for a server without dependencies on operating system, applications, or physical hardware.
