As customers pack more virtual machines on physical servers, storage I/O bottlenecks that impact performance are unavoidable. Because of this, customers are limited to the number of applications they can move to virtual machines. Native tools address part of the problem, but do not provide granular I/O policies to keep performance and data availability at an optimal level.
Symantec solves the entire problem with Veritas Dynamic Multi-Pathing (DMP) for VMware. DMP for VMware is a solution that helps customers optimize performance and keep data available, even when a path fails. DMP for VMware distributes I/O from server to storage based on seven pre-defined policies. These policies can be employed based on workload characteristics like read/write ratio, block size or sequential versus random access. DMP for VMware includes visibility of the environment to not only show how paths are mapped from server to storage, but also the I/O traffic residing on those paths. With this visibility, customers can identify SAN bottlenecks and make changes to policy without impacting the application or availability of the data.
Additionally, Symantec announced support for VMware vSphere 5.0 at VMworld this week.
