Looking at it that way, VMware is another virtualization layer and the x86 is another hardware environment for Symantec / Veritas to support. In production environments, Veritas has the experience both in availability and disaster recovery and application awareness that can make the use of virtualization practical.
Features that Veritas provides include one-click failover, centralized management, non disruptive disaster recovery testing and expanded role based management of both physical server and virtual machines.
Application performance management comes with the addition of Veritas Application Director. As you might expect, the suite of applications manageable includes the usual x86 apps, such the Microsoft back office suite and other popular apps. Since Veritas delves into managing the both the virtualization layer and the OS layer, OS support is an issue. However the list is extensive including 64 and 32 bit versions of Windows, Linux and Solaris.
The Veritas tools are robust and they're priced like it. Expect to pay more for Veritas Cluster Server than you did for VMware itself.
