While I realize that the most common answer would be 'depends on what you need or are doing', I am curious as to how others go about this. In my dev setup, I have three FC chassis with 1TB of storage on each. One of the chassis act's as the RAID controller for the other two. I can have one large volume or many small one's. My storage/GFS needs are mostly based on hosting web/php/mysql services. In my case, I've split storage up as one large volume for MySQL and two smaller one's for web and then mail services. It would be simpler to have one single large volume but I'm not sure about performance or other things such as security. If someone made it in, they would have access to only one area, web or mail or mysql for example. What are some of the reasons to use either way, multiple or single volume?
