So.... worked at a telco on a telco cloud solution, and ipv4 addresses are expensive.
LAN/RFC1918 doesn't work at scale of hundreds/thousands of data centers(each central office was a data center)
as such ipv6...
Still had some legacy tools that relied on ipv4, but ipv6 was basically the only way to fix some of their issues with data normalization in their IPAM etc.
Also, having to provision and manage these servers with people and flash drives and keyboards and bios settings was suboptimal.
Insert multiple racks ... hundreds of them inside the same data center, multiple vlan's(reasons) some good ... some not ... l2 at that scale had issues.
Wanted to just turn them on with a firmware/boot agent that would connect to a provisioning server and download their OS and bios settings.
as such we built something that was basically the replacement for an iDRAC/ILO :) and ran on actual factual ipv6 first.
some nic's still let you burn into the ROM your own boot loader... can't say more for NDA reasons though I doubt anyone is using this as the whole product got subsumed by the public cloud push.
But for cabling, OS2 clear bend rated cable … pre-terminated is like the same price and currently have 25gb optics but I’m able to run over 100gb in my house without having to drill holes etc. (runs along the baseboards)
The cables are super thin… and clear/transparent
And I never have to replace the cable again I’m pretty sure haha
The bidi sfp28s $25 are awesome :)
And worst case if your service loop just … loops …. Eh haha
Gonna try using it for other things like hdmi etc too with a cassette :)
