Virtualisation ROI hard to quantify

Server virtualisation is becoming more popular in enterprise data centres, but a recent survey says that doesn't necessarily mean the technology has proven itself successful when deployed.

CA this week released the findings of a study showing that more than 40 percent of 800 IT organisations polled worldwide were uncertain if their use of server virtualisation technology was successful.

"In fact, 44 percent of the organisations that have deployed server virtualisation are unable to say whether or not the deployment has been successful -- pointing to problems with measurement negatively influencing server virtualisation satisfaction levels [for example] measuring server and network infrastructure performance," reads the report, which The Strategic Counsel conducted on behalf of CA.

The research firm estimates that 39 percent of organisations with more than 500 employees have adopted server virtualisation technology, and it expects that figure to grow by 20 percent over the next 18 months. Such uptake in the adoption of virtual servers will shine a light on some issues around managing the technology , the report says.

'The pattern of organisational server virtualisation deployment has led to the creation of multiple, heterogeneous server virtualisation environments within single organisations. That is the norm shown by the survey, not the exception," the report reads. "With heterogeneity comes management issues and constraints."

According to the survey, those organisations with heterogeneous server environments are already experiencing a few key management problems, including server sprawl, configuration workload changes, difficulties in reporting and staff skill set limitations. Specifically, 39 percent of organisations that run multiple server virtualisation technologies indicated they suffer from server sprawl.

"The future of server virtualisation will be just as much about virtualisation itself as it is about managing multiple, heterogeneous server virtualisation environments," the report concludes.
