• Question 105:

  Which two resources are the most impacted in the infrastructure sprawl experienced in non-virtualized data centers? (Choose two)

  A. Power

  B. storage

  C. Compute

  D. Network

  Correct Answer: AC

  Explanation: The initial motivator to move to virtualization was server consolidation. Server sprawl was a very big problem in the "1 app, 1 server" datacenter environment. Hundreds of servers were using power, generating heat, taking up space, and requiring administration. On topof that, the great majority of these servers were woefully underutilized, using just a fraction of their CPU and memory. It was a completely inefficient way to run a datacenter. Virtualization allowed one physical server to be shared by multiple VMs. In the early days, you could get ratios of 20 to 1--this represented significant cost savings to the business. Over time, these ratios have grown, and it is not uncommon to see ratios of 100 to 1 now.
