The big picture approach to virtualisation

The big picture approach to virtualisation

Here are five key considerations for CIOs and IT leaders who want to ensure that they are taking a holistic view of virtualisation.

In the current economic climate, organizations are cutting IT projects that are unable to show a strong return on investment within twelve months. But buoyed by the prospect of increased efficiency, lower costs, quick return on investment, and a more flexible model to align with primary business functions, virtualisation is one of the IT projects getting almost universal buy-in from CIOs.

While server virtualisation is delivering on these benefits in the data center, many CIOs are now responding to the unintended consequences and complexities that are being created. These include virtual server sprawl, a lack of full realization of benefits, and increased shared storage costs, among others.

Here are five key considerations for CIOs and IT leaders who want to ensure that they are taking a holistic view of virtualisation.

1. Assess your virtual environment readiness

You can't optimize what can't measure. Detailed assessment is required before full project commitment to understand your current capabilities, help justify current and future investments, and provide a baseline measurement that can be tracked and reviewed.

2. Investigate shared/unified storage to improve flexibility

A well-architected shared storage environment can help IT groups enable the advanced features of virtualised server environments without adding the overhead of additional management.

3. Revisit data backup and recovery plans

virtualisation means relying on fewer physical systems to process more tasks. Consolidating on fewer machines without redesigning data protection will lead to performance issues, impede recovery and limit overall project success. CIOs should carefully consider the best choice in data protection for their organization's specific needs, to minimize the impact of events such as data, system, or site failure and ensure information is properly protected.

4. Consider thin provisioning

Server virtualisation enables the rapid provisioning of applications and administrators should consider thin provisioning for their environments to reclaim unused storage, improve storage efficiency and enable faster time to market.

5. Dig into data deduplication to maximize efficiency

By its very nature, virtualisation tends to have a lot of duplicate data such as the same operating system and application software. Deduplication technologies allow an organization to use and manage less storage while still reaping the benefits of virtualisation.
