I'm looking to do some upgrading of my home network to more commercial level gear and learn more about networking in the process. I've been looking on ebay for used network switches in the 16 - 24 port range. I'm pretty sure I want a managed switch as I'd like to try out link aggregation between my main workstation and my file server, but beyond that I'm not really sure if i'm looking at junk or a good deal. I see Dell Powerconnect 5324's show up quite a bit would this be a solid choice? Currently my network consists of the following - 100/30 Internet Connection - Basic Wifi Modem/Router - Windows 2012 R2 Essentials (File Server) - Windows 7 (main workstation) - A few other random computers I plan to add the following - A pfsense box - VM Server - Possibly another file server to store backups I was using an 8 port Netgear GS608 but it recently died which is a big reason I'm looking for a new switch. Any recommendations for good switches to keep an eye out for would be appreciated.
