About Capacity planning for virtualization

As you expand a server virtualization deployment, your server capacity planning and resource allocation challenges are bound to become increasingly complex. How do you decide which workloads to allocate virtual machines (VMs), how do you measure these workloads in an increasingly mobile, dynamic and virtualized environment, and which server capacity planning tools can help you set policies to reallocate these workloads, load-balance VMs, and automate what are frequently manual processes? In this section on capacity planning for virtualization, we offer news, research and tutorials on using capacity planning tools in your virtualized environment and break down how to use virtual server capacity planning tools to relieve your organization from fire-fighting mode and move it into proactive, long-term planning mode for your virtualized deployments.
