Hi list! I am running a website with several thousand of images on a Mac Mini. I have done that for about a year but I feel that I need something more secure then a single Mac mini and a WD elements external USB drive for the images. If my Mac Mini goes dow for example the website is gone and that is not acceptable. I want to build a solution with HAPROXY. I want to add more Mac Minis in the future running Round Robin. I am thinking of buying a Synology NAS of some kind to store all images. Maybe with 10 harddrives to begin with and expand when I need to. Later on I will build a similar system in a different geographical position. Lets call these two system A and B. Lets talk about system A. I understand that I need at least 3 Mac minis to make this happen. Mac mini 1 running HAPROXY (round robin). Mac mini 2 and 3 running the website. So if Mac mini 2 or 3 goes down for some reason the other one will continue run the website. It will also be much easier to upgrade one Mac mini if I can just shut it down and the other one will still run the website. I think I understand the concept of HAPROXY so far. Now to the part I don't understand. Do I need a storage array for every Mac mini I have (Mac mini 2 and 3) or should they share a single storage array? I have been looking at ISCSI and it seems to be the way to go but I have just learn that it can only be one initiator connected to the same target at the same time. Lets talk about system B. If I build a similar system like A but on a different geographical position, how should system A and B interact with each other (with HAPROXY) to make everything secure? Can I continue to use HAPROXY and round robin takes care of 4 Mac minis? I have more questions but let's start here and see where it takes me.
