Server virtualization has many benefits for your business including reduced costs and improved rack space. By taking advantage of virtualization, you will see improvements in energy usage due to reduced cooling requirements as well as improved disaster recovery and more flexibility. Planning ahead of time can minimize the risk of a system wide disaster and should be highly considered before starting a new virtualization project. Take a look at these 6 steps to server virtualization.
1. ALWAYS HAVE A BACKUP IN MIND
It is important to consider the worst-case scenarios, including natural disasters and physical harm to hardware. Because back-ups are so important, consider redundant back-ups in case of any hardware failure, which could wipe out everything.
2. DEVELOP A LONG-TERM PLAN
When considering virtualization, make sure that it fits into your long-term IT plan and does not conflict with other decisions. There are some situations where virtualization may cause complications, such as having multiple systems with components that to not work well in a virtual environment, including fax systems. For the most part, virtualization can help reduce costs and keep hardware more organized.
3. PRIORITIZE HAVING A LOT OF MEMORY
When planning ahead, intend to get more memory than you need. An average of 2 gigs of dedicated memory per server installation is standard, but it is always better to have more memory than expected so that you don't run out of space. Processing power is generally underutilized but memory and storage generally are needed in excess. In the case of server failure, having extra memory on another server allows programs to still be run while the server is being repaired.
4. CONSIDER MULTIPLE STORAGE SYSTEMS FOR REDUNDANCY
When considering a storage manufacturer, it is important to take into account quality, support, and integration into a virtual environment. You should also consider compatibility with your tape drive solution and make sure that you have enough disk space to allocate new server installations. Always prepare for the worst case, including drive failure.
5. VIRTUALIZE YOUR SERVERS IN PHASES
Although it may be exciting to begin virtualization, try not to get caught up in virtualizing all at once. You should test applications before deploying them since not all applications will react well in a virtual environment. Manufacturers may offer support within a virtual machine if needed. Virtualize in phases to ensure that every application will fit well and is thoroughly tested.
