We are planing for file server in our environment, Please let me know which option is good for file server (Physical\Virtual) and why. I need to share recommendation to our client. Thanks in advance for your suggestion.
Your case here would be based on the benefits of virtualisation in general rather than best practices for a file server. File servers do not to tend to be seen as resource intensive and requiring special configuration in a virtual environment as opposed to a physical. You should sell the HA, backup and disaster recovery benefits of virtualisation over physical implementations.
What are the customers stance on physical/virtual and their concerns? what does the file server/s mean to their business i.e. are they critical? why are they reluctant to virtualise?
