Knowledge about storage usage in SAN & NAS

Hi experts, I'm new to this forum and have a very basic question. I've joined a new team and have to manage infrastructure (this will be my new experience as well). Unfortunately there is no history of how our app data is stored across SAN and/or NAS. The server we are using uses SAN as well as NAS filers. So how should is start with collecting all data? What should be the questions that I should look forward to? Is there any approach to collate all the storage related data? Sorry if my question feel stupid but it's very important to me. Any help/guidance would be appreciated.

    There is no such thing as a stupid question.

    I'm no storage expert, so we will have to wait for someone to provide some insight.

    Wow, I though some people would have answered this.
    I would attack the problem in the following way.

    • Talk to other people on the IT Team who know the systems already.
    • If you have vCenter, Download and run RVTools against it. This will give you ~60% of what you need.
    • Next look at the SAN (Block) storage array and make a list of the present volumes to which hosts.
    • A proper naming convention here will help a lot. Disk234 doesn't tell you much, but Oracle_Cluster_RDM5 says a lot more.
    • Next with the NAS (File) storage. Look at the Shares that are presented. The names and contents should tell you a lot about the function of the storage
    • Some NAS & SAN Arrays have plug ins for vCenter & the OS's these will help you trace the connection between application to Disk.
    • Visio or something like it will help you visualize the connections between tiers.
    This is a subject everyone in a large storage environment probably struggles with. So don't feel disheartened if it seems like an impossible task. It eventually will all start making sense
