Thanks for your response Pranith and Mathieu, Pranith: To answer your question, I am planning to use this storage for two main workloads.
1. As a shared storage for VMs. 2. As a NFS Storage for files. We are a online backup company so we store few hundred Terra bytes of data. Mathieu: I appreciate your concern, however as a system admins sometimes we get paranoid and try to control everything under the Sun. I know I can only control what I can. Having said that, No, I have pair of servers to start with so at the moment I am just evaluating and preparing for proof of concept, after which I am going to propose to my management, if they are happy then we will proceed further.
