I think I've had a switch failure. I'm currently away from home, on Wednesday evening when I was remote desktop into my home PC to configure Proxmox on my new box, everything stopped working. I was unable to connect to anything in the home. Luckily, after the scheduled routine router restart during early hours of Friday morning, I am now able to connect to a small amount of devices, all devices connected directly to the router (wired or wireless) now responds and works. This leads me to believe my 8 ports main switch has died. So, I'm taking this opportunity to upgrade to 2.5 GbE. The plan is as follow: From: Code: PC Synology NAS HP microserver for backup \ \ / Router ----- 8 port gigE switch ----- 5 port gigE switch / \ energy mon laptops and others TO: Code: PC existing Synology NAS with USB 2.5GbE HP microserver \ / \ / Router ----- 2.5GbE 5 port switch ----- 5/8 port gigE switch ----- 5 port gigE switch / \ energy mon laptops and others Question (1) is, will traffic always take the shortest route? If I do a transfer on PC to NAS using machine name (rather than IP), will I always get the 2+GbE speed? Keeping in mind all switches are unmanaged and router is a consumer grade Asus AC68u. Because this USB dongle method is not officially supported by Synology for the NAS, I need to keep the 1GbE connection just in-case. Hence keeping the 5 port switch in the cupboard with HP microserver. So, capitalising on that, I'm also thinking of running another ethernet cable from router to the 5 port switch in the cupboard with the servers. So that in case of another switch failure, I can still access data at home. How would network traffic work if I basically create a ring topology layout using 3 switches and a router? Summary of question 2 would be, are redundancies within an ethernet network just exactly that? It wouldn't confuse data packet routing, etc? Is there any configuration required to set up this kind of redundancy?
