whitepaperYour VM Perplexities Called, and They Need You to Read This.

Virtualization can give you enormous flexibility with future workloads and can be a key enabler for other areas, like cloud computing and disaster recovery. So, how can you get a handle on the performance challenges in your virtual environment and manage deployments without erasing the potential upside? Learn the four key areas you need to be focusing on to help deliver a healthy and well-performing data center.

The minimum memory requirement is 8 GB, but more memory might be necessary to handle peak demands. You can reduce the memory requirement for collecting from multiple vCenters (VC) in these ways:

  • Schedule the configuration data collection jobs for the different VCs in a way that they do not overlap, by setting the start times at least three hours apart. This also means reducing the frequency of configuration collection to one or two times per day.
  • Instead of using the actual total number of ESX hosts in the environment, calculate an approximate number of hosts according to the formula:
    1. Take the largest number of hosts managed by a single VC instance.
    2. Add 15% for each additional VC in your environment, regardless of its size.

For example, if you have three VCs and the largest VC manages 90 hosts, your "proxy number of hosts" is 117.

117 = 90 + 0.15 x 90 + 0.15 x 90

The number of ESX hosts above is guidance only, and is based on a typical virtualization environment with approximately 10 VMs and one datastore per ESX host server. More dense environments require larger memory sizes.
