Over half of IT Managers 'failed to realise benefits of virtualisation'
Fewer than 50 per cent of organisations that have deployed virtual networking infrastructure and applications have realised significant operational cost or resource savings and return on investment is yet to be delivered, says a study by Network Instruments. However, 45 per cent concede the technology's benefits outweigh the constraints.
Network Instruments questioned 120 network engineers, IT managers, and executives attending the Interop event in Las Vegas last week (17-21 May). The survey also revealed that:
- 55 per cent of global organisations have mission-critical virtual servers, including email and Web servers.
- 50 per cent run virtual DNS and DHCP servers.
- 39 per cent have extended virtualisation to the desktop.
In terms of key concerns, respondents cited:
- Lack of data and application visibility, the greatest troubleshooting challenge in virtual environments – 27 per cent.
- Lack of virtual infrastructure training is impacting success – 26 per cent.
- Inability to secure a virtual network causes great concern – 21 per cent.
- Lack appropriate experience to manage the technology – 59 per cent.
- Roll-out costs were too high – 47 per cent.
"Many of the people we're speaking with have implemented virtualisation, but often lack of visibility is keeping them from realising the benefits of the technology," says Ian Cummins, VP EMEA of Network Instruments.
