@JJ75214877 😂 jo i ne, chce to vidět big picture… 1/ LACP/ECMP má hash - když se to špatně sejde, bude to furt jen 25G, 2/ Seznam řeší redundanci na úrovni clusterů, vše je stavěno že cokoliv může kdykoliv selhat => afaik většina serveru single homed. viz. youtu.be/Ui3_SO6dDJc

Letošní ročník konference LinuxDays se uskuteční o víkendu 4. a 5. října, opět se potkáme v pražských Dejvicích na FIT ČVUT. Také během letošního ročníku nás budou čekat desítky přednášek, workshopy, stánky a spousta doprovodného programu. linuxdays.cz/2025/

@bycaldr 👍 Tušíš na jakém to běží podkladu/HW? Ampere Altra?
@adamjezek98 Co to je za “archiv”, že k tomu máš kabel s SC? :O
Tak a zase po roce, jsou tu další Vánoce… ehh, teda cože? Narozeniny informačního systému klubu @Silicon_Hill, konkrétně 12. a podobně jako tomu bylo loni, i letos jsme k tomu přidali další kolejní síťový klub - Orlík. 🎉 Dík za pomoc @staypekos
Am I the only one, who completely missed, that some of the Cisco Nexus datacenter switches now support PoE? 🤯 What is the main usecase for that? Is it meant for "IP Fabric for media" SMPTE 2110 UPoE powered cameras? Powering DC non-IT infra? something else?
@CSOB_CZ prosim, kdo vam kde vykradl databazi emailu? Odkaz je samozrejme tinyurl a domena odesilatele taky nesedi...
@vpecinka Na Strahovském kopečku bychom určitě něco užili, akorát mi nejde Vám napsat DM.

Playing snake on @Ubiquiti Etherlighting switch. Most expensive gaming console I own. Game selection is pretty limited due to the poor resolution. They went overkill on ethernet connectivity but forgot about other ports, I can't even plug in my gamepad. But it has RGB. 9/10
@AdjacentNode Not someone, this is @adamjezek98 ‘s video and work 🙂
@adamjezek98 @Ubiquiti 😂 at least for something are those things useful, but switching is not it.
@adamjezek98 Doufám, že jsi za ten elektroodpad nemusel platit 🙃
@adamjezek98 Jj rack u/očesat o, jestli správně vidím, 3U krabic nejmenovaného výrobce 🙃
@darklordoflinux @adamjezek98 Chvíli jsme měli 40G, teď máme 25G a lusknutím prstu (zapojením transcieverů) umíme 2x 25G po SH, co v tom je 2port ConnectX-4 síťovka… Zatím ale čekáme na výměnu uplinku na B1-KN z 10G na 2x 100G prý. Původně mělo být 2x 25G, ale pak nějak vymysleli, jak sem dostat 2x 100G.
@NetEng_Ian @kystokes Yep, GPT is right, this street is called after Ronald Reagan. Second line with smaller size is part of Prague (I would refer Prague 6 as similarly to Manhattan, Brooklyn etc.). Usually in smaller cities signs show only street name, not part of city.
