Networking
Normally I was going to post a few words about A.I. as it is the most hot subject of this year and I invest a lot of time into studying that and trying to catch with all new breakthroughs about it,
BUT a few major important (relatively new products and price updates) caught my eye by hearing I.T nerds talking about.
And that is, building high demanding networks is no more worth the price of your both livers and your weight in gold.
#1. Routers
Years back if you encountered a router that wasn’t performing well for your large network you would have to either build a server for that or put your hand deep into your pocket, for advanced settings, such as, a fail-over gateway (internet backup), a firewall, etc.. you would have to invest in a Cisco, in worst case a Mikrotik, Now you got for around only 250$ that bad boys:
Which operates with an NVme SSD, DDR4 ram, a powerful “MiniPCs” with Intel processors, that can be used with OpenWRT or Pfsense, In fact you can find them on AliExpress by just searching for PfSense.
You can buy from €89.12 the above now by clicking here safely and tested.
[[[Joke attempt: If you never heard of Pfsense or OpenWRT but you got your CCNA (Cisco) certification go ahead and apply for a job at “Network Clown Services”! or Apple. coz u are an apple fanboy too, whatever 🤡😜 ]]]
The capabilities they offer when running a router – firewall software are quite over the level to support a big business (At least what is considered to be big in my country) which doesn’t have higher demands than transferring more than 2.5Gbps to the internet. Whatever business except ISP business or data center business, or a 40 floor business with 80 offices each where all floors are an internet café station and they need to play LOL at low ping, or CERN experiment business.. (not sure if CERN facilities need to upload at a higher rate of 2.5gps .. just saying lol)
#2. 10 Gigabit Ethernet.
All comes down to SFP+ (note, +) ( At introduction, typical speeds were 1 Gbit/s for Ethernet SFPs and up to 4 Gbit/s for Fibre Channel SFP modules.[4] In 2006, SFP+ specification brought speeds up to 10 Gbit/s and the SFP28 iteration is designed for speeds of 25 Gbit/s ) https://en.wikipedia.org/wiki/Small_Form-factor_Pluggable
Now starting from 70$ You can get a PCI-Express NIC but that is not the big news, the big news is from 100$ to 150$ You can get 10gb Switches with at least 8 ports.
At that price range there are either 8 SFP+ port switches or a combination of 7 x 2.5gbs Port + 1 SPF+ port. such as. TP-Link TL-ST1008F, or HORACO 8 Port 2.5G Ethernet Switch 2.5GBASE-T
If you want to ensure a 10 Gigabit link for your terminals, using fiber optics is generally a more reliable and suitable option compared to Cat5 cables. Fiber optic cables can support higher speeds and longer distances without experiencing signal degradation. Each Cat5 or cat6 cable will need to be replaced with a pair of 2 x fiber optics (rx/tx)
if the distance is within 30 meters and you want to maintain your existing Cat5 infrastructure, you can use appropriate RJ45 SPF+ copper modules. These modules allow you to use fiber optic transceivers on the switch side and connect them to the Cat5 cables using the RJ45 interface. This way, you can achieve a 10 Gigabit link while still utilizing your existing cabling infrastructure.
Consider factors such as the distance, required bandwidth, and potential future expansion when making a decision on whether to upgrade to fiber optics or use RJ45 SPF+ copper modules.
Thats all kiddos.
