I am planning a large file server and I would like your advice and suggestions. We currently have 4TB of data and I anticipate, based on growth history, we will grow to 25TB within the next 5 years. I am planning our storage infrastructure for this. Our files are 95% .jpg files and 5% word documents, excel docs and other misc. documents. We have 2 servers. One in building A and one in Building B (DR Site) that are connected via GB LAN. The plan is to replicate the data from serverA to ServerB using DFSR. This will provide high availability in the event of a failure on ServerA. We also have a 3rd server in buildingB that is a DPM2010 server which will backup this data.
I am trying to decide between to options and would like to know your input and advise.
Option 1: Split our data into 4 volumes and then grow those volumes over time by adding storage and spanning each disk as necessary.
Option 2: Put all data on the same volume and grow that one volume over time by adding storage and spanning the disk.
Taking into account our scenario, which decision do you recommend and why?
