VMware vSphere® delivers maximum availability for your virtualized environment, making planned downtime a thing of the past and minimizing unplanned downtime through automated virtual machine restart. Automating virtual machine placement and load balancing, backup and recovery and site-wide disaster recovery further enhances availability.

About Availability

Eliminate Planned Downtime

VMware vSphere® vMotion® allows you to migrate live virtual machines from one vSphere host to another with no impact on end users. This way, you can perform server maintenance and upgrades without having to schedule downtime or disrupt business operations. With vSphere vMotion, you can dynamically reconfigure virtual machine placement across vSphere servers—to align with changing business policies or proactively move virtual machines away from failing or underperforming hardware.

VMware vSphere® Storage vMotion® lets you move virtual machine disk files from one datastore to another without disrupting service to the end user. You can take control of storage operations by simplifying storage array migrations, maintenance and upgrades and by dynamically optimizing storage I/O performance.

VMware vSphere® High Availability (HA) provides easy-to-use, cost effective high availability for applications running in virtual machines. In the event of physical server failure, affected virtual machines are automatically restarted on other servers with spare capacity. In the case of operating system failure, vSphere HA restarts the affected virtual machine on the same physical server.

Optimize Server and Storage Usage

VMware vSphere® Distributed Resource Scheduler (DRS) continuously monitors CPU and memory utilization across a cluster of vSphere hosts, allocating resources among virtual machines according to business needs.

VMware vSphere® Storage DRS™ positions workloads on storage volumes during provisioning based on available storage resources. It also performs ongoing load balancing between datastores to prevent space and I/O bottlenecks.

Features

High Availability

High Availability (HA) provides cost-effective business continuity for applications running in virtual machines. If a physical server goes down, affected virtual machines are automatically restarted on other servers with spare capacity. Should an operating system fail, vSphere HA restarts the affected virtual machine on the same physical server.

Data Protection

VMware vSphere® Data Protection™ (VDP) is the ideal backup and recovery solution, providing efficient backups to disk and dependable recovery. VDP technology satisfies business requirements by eliminating the high cost and complexity of traditional approaches.

App HA

vSphere App HA is a new feature that complements the functionality of vSphere HA with application-level monitoring and automated remediation. App HA improves application uptime through policy-based application monitoring and remediation, as well as integration with vSphere HA to provide multiple recovery options.

Fault Tolerance

VMware vSphere® Fault Tolerance (FT) delivers continuous availability for applications, protecting against hardware failures by creating a live, shadow instance of a virtual machine that is in virtual lockstep with the primary instance. With immediate failover between two instances, FT eliminates even the smallest chance of data loss or disruption.

Replication

vSphere Replication lets you replicate powered-on virtual machines over the network from one vSphere host to another without storage array-based native replication. Unique advantages include reduced bandwidth requirements, no storage lock-in and the ability to create flexible disaster recovery configurations.
