Results of an end-user survey at ESG's Ahead of the Curve event

With an initial server virtualization implementation, it’s relatively simple to get to the point where you see the value and want to do more, but planning for that next phase is difficult. IT professionals attending ESG’s Ahead of the Curve summit were asked about some of their biggest challenges when it comes to choosing server hardware for a virtualized environment: IT organizations continue to struggle with capacity planning and rightsizing. They want to move ahead, but I often see one of two methods:

  1. You go procure more servers and leave yourself plenty of overhead–lucky you.
  2. You don’t have the luxury of disposable capital and have to get really smart about how to plan and consume capacity on the virtualized platform. This often causes virtual stall due to lack of visibility, reporting, and analytics.

Here are a few suggestions:

  1. Know your workloads: how they behave and if they do so with predictability or have erratic behavior.
  2. Plan for automation and learn to trust the tools. Even if you continue to make changes manually, learn when and were to apply automation early in the process.
