Capacity Optimization

Rightsizing resources allocated to a VM combined with reclaiming wasted and abandoned resources drives large ROI savings in storage and servers.

Right Sizing Resources

The initial amount of CPU, memory and storage required to support a VM is many times based on best case estimates from when an application was operating in the physical world. These estimates are generally increased to provide a safety factor in an attempt to ensure VM performance during initial application roll out. The result is over-provisioned resources to VMs.

By comparing provisioned CPU, memory, and storage against peak and average utilization over a 30-day or more period, it is possible to safely reduce the amount of CPU, memory and storage allocated a VM.

Using VKernel's Optimization Pack, system administrators can right-size resources to a VM and save up to 25% of a virtualized server environment safely, quickly and easily.

Reclaiming Wasted Resources

Over the course of standard operations, organizations inadvertently start to waste CPU, memory and storage resources. These resources are unknowingly wasted through the following accumulations:

  • Snapshot and templates that have not been used and are obsolete
  • Disk images that are not registered in vCenter and are therefore abandoned
  • VMs that are operating at a low level of utilization without any change over the proceeding days and hence are declared to be abandoned or in a Zombie state

Unused snapshots, templates and disk images all contribute to wasted storage resources. Zombie VMs consume memory and CPU resources, along with storage. VKernel's Optimization Pack is designed to uncover and find these wasted resources quickly and effectively saving up to 25% of storage, memory or server resources.
