Reasons For Adopting Virtualisation
Virtualisation leads to great benefits, including: • Server Consolidation
– Consolidate multiple servers into one single physical server for improved operational performance
• Reduced Business Costs – As physical servers decrease, so do costs of infrastructure, space, etc.
• Improved Application Security– Separate applications in each virtual machine segregates vulnerability
so to not affect other applications• Reduced Maintenance
– Virtual servers can easily be relocated and migrated, maintenance of hardware and software can be done with minimal downtime.
• Enhanced Scalability– The ease with which virtual servers can be deployed will result in
improved scalability of IT implementation.

Business Benefits of Consolidation
• The management of servers, storage and network devices can be greatly simplified
• Energy costs can be reduced • License fees and maintenance costs can be
brought under control • Less data center spaceServer and Storage consolidation results in
reduced software and equipment costs, improved productivity, and lower
operating costs.

Problems To Avoid
• Taking the piecemeal approach to infrastructure build-out – Beware of the headaches that can come from an overly complex
infrastructure.• Keeping with outdated processes
– Processes used with physical servers may not translate to the new environment
– Keeping physical server processes can ignore the unique benefits of a virtual environment
• A longer learning curve translates into slower gains– Poor or little knowledge transfer or training prior to or during
deployment• Struggling through product compatibility headaches

Top Drivers for Virtualization
1. Get more out of your existing resourcesConsolidate servers to gain resource efficiency
2. Reduce your physical infrastructureFewer servers and related IT hardware means reduced real estate, power and cooling, and personnel requirements
3. Increase availability of hardware and applicationsImprove business continuity by securely backing up and migrating entire virtual environments with no interruption in service
4. Gain operational flexibilityRespond to market changes with dynamic resource management, faster server provisioning and improved desktop and application deployment Datacenter Resources

Virtualization’s Impact on Storage
StorageConsolidation
Physical server reduction has led to an increased dependence on
scalable networked storage arrays
Increased Performance Requirements
As storage is consolidated, each array must process more difficult,
unpredictable workloads and sustain higher levels of I/O

Challenges for IT Managers
Managing storage and protecting data in a virtualized environment presents new challenges to IT managers…
How complex is provisioning?
Will you need to learn an additional storage management tool?
What will it take to implement and manage important data protection features like mirroring and replication?
