(random thought) It surprises me how, despite working in the tech industry for over a 15 years now, I struggled in following the details of this blog post (which is well written). It's so impressive how things got very complex over time, and how verticalize the role of an Engineer is becoming.
- NavinF 5y agoI feel like things have gotten a lot simpler over time. Examples: 1. There's only one relevant type of optics (Q)SFP(+)(28) instead of many incompatible ones. Line cards have become uncommon. 2. Everything runs Linux so he can just run tcpdump instead of some vendor specific monitor command. 3. 10G ethernet and 56G infiniband are dirt cheap so now there’s a large online community for homelabs that use data center hardware. Nobody needs to be a network guy to run a data center.
- sliken 5y agoI'm looking to upgrade my 1G home network to a mix of 10+2.5G (including PoE) Which "large online communities" where you thinking of?
- NavinF 5y agoThe main one is https://forums.servethehome.com/index.php https://forums.servethehome.com/index.php Also /r/homelab Search eBay for “10g card” and google the cheapest model number to find the rest :)
- kazen44 5y ago> Nobody needs to be a network guy to run a data center. the complexity from networking at a DC mainly comes from scale. running enterprsie/dc hardware in a homelab is vastly different from running it in production.
- hansel_der 5y agoyour argument seems to hinge on the perspective on "scale" i.e. enthusiast homelabs from today have sufficient capacity/performance to accomodate production scenarios ("at scale") from 20y ago. besides the need for appreciation of ones work, everybody, all the time, is cooking with water.
- kazen44 5y agowhat i actually meant to say was that multitenancy makes networking complex. (and nearly any network is multi-tenant once it reaches a certain scale). Also, depending on the services which run on the network, more complex technology like MPLS/VXLAN-EVPN is needed.
- ghosty141 5y ago>running enterprsie/dc hardware in a homelab is vastly different from running it in production. This applies to all of software. Enterprise and "home" diverged quite a lot. Back in the 2000s running a webserver at home was roughly similar to doing it for a company. Nowadays they are nothing alike with all the load balancing, caching etc. etc.
