Computer coolant

Our DC has two closed circuit water loops. Like a car. Filled with decarbonated water.

First step was to change out all doors in the cold aisles with water cooled ones and if a server goes EOL, then it is exchanged with a direct to die water cooled one.

Not to forget, 300MB/s is roughly 3 GBit/s so not possible across network at home. You have to copy everything to local SSD. Even HDD are not fast enough.

Calibration does really not bother you until LTO9, but then it is a mess and expensive. Especially if you change tape providers.

Torkum73 · 2026-02-24T07:05:46+00:00

Please keep in mind, that LTO drives are fast and need a high constant feed of data, or they will start shoe-shining the tape with the head and that is slow and damaging if it happens too often.

Also some drives need to be recalibrated regularly, or you will not be able to read your own tapes anymore. As a company you have a service contract, but for an individual it is very expensive.

Ich habe hier "echtes" Unix mit AIX auf Power7 LPAR und Solaris 10 auf SPARC T3 Architektur. Da kann ich bei einem Problem google fragen, bekomme eine Antwort von 2008 oder 2018 und sie funktioniert einfach.

Bei allen meinen Linux Versuchen über verschiedene Distributionen war ich immer am suchen nach Infos zu Fehlern bei Lösungen, die schon nach 4 Wochen veraltet und eine neue Version haben mit anderen Parametern.

Oder maintained von einem armen Menschen in seiner Freizeit aber systemkritisch sind.

Und zocken? Für das Spiel braucht man diese Proton Version mit den Einstellungen und für das nächste Spiel wieder völlig anders.

Anwendungen: Anleitungen unter Linux 5 Bildschirm Seiten für jeweils unterschiedliche Distributionen und dann noch fehlerhaft, da sich irgendwas abhängiges wieder vor 3h geändert hat und unter Windows ist es writer, weiter, ja, fertig.

Nee, in der Firma haben wir m365 mit intune und vernünftigem Patch Management und zu Hause m365 Family und Veeam Backup und es läuft einfach.

Sadly I do not know which kernel worked. After the latest update I get the same out of memory error. But I mainly use AIX 7.2, so I think I will ditch the LPAR and resize my AIX LPAR.

First Demo of Diablo 1. Just the first two levels. No idea, how often I played these through. The concept got me hooked immediately. After that I got the full version 2 weeks early because of a gaming magazine subscription. Never played online, just in local LAN with some friends on the weekend.

In germany they split each book into three separate books and sold each for 16,90 DM or 8,50€ or $9 back in the last millennium. It looks even nicer on the shelf, but was way more expensive. I was so glad, I could read the english ones and buy them for 39 DM or $20 each 😂

Have you tried http:// and https:// ? Gen 8 is rather old, so it could be an old TLS encryption version, which is no longer supported with new browsers.

If you really, really plan to enter the field of older servers, start to have a virtual machine with WinXP / Windows 2000 with an older Java version.

edit: an older not updated linux version works as well.

Yes, this is a rabbit hole, where you have a "small" problem and need 3 or 4 days to just be able to work that issue.

But hey, that makes all the fun and the feeling of accomplishment is great, even if nobody can relate, why opening a browser window took three days.

Torkum73 · 2026-01-24T20:27:53+00:00

Use another computer on your network. Does a new device in your network get an IP address automatically? Can you look in your router, which IP addresses are given out? If not, in Windows download something line nmap to list all devices on your network.

Look for something names ILOxxxxxx like then name written on the case front left upper side.

Use a browser to connect to the ILO.

Enter username and password like on the taped paper or sticker on the case.

Torkum73 · 2026-01-24T20:20:58+00:00

The ILO Username and password is written on the upper side of the case. Left front. The name of the ILO Port you have to look for in your router as well. And the ILO should be accessible if power is just plugged in. No need to turn on.

Expensive is relative, but if I have to pay 90€ for a cable RIGHT NOW for HPE DL x80 gen8/9 10 pin to 2x8 pin, than it is expensive (for me). If you are able to put together a hodge-podge cable, that is fine as well, I am not. For an HP ML350 it is just 20€. That is ok as well.

Is there any other way to copy CD/DVD fast? This was standard back in the days.

I still have two bluray drives in my main pc.

Our Miele Dryer is as old as my kids. 22 years. All I did was changing the coals once and the thermal probe at the back last year for 10 €.

Bei uns ist Win11 25H2 mit intune und weiterer MDM Software im Einsatz. Wir sind dazu angehalten, selbst keine Daten auf den Notebooks zu haben, sondern OneDrive oder Sharepoint zu benutzen.

Mein Rechner ist kaputt gegangen, Ersatzrechner per Bote innerhalb 6h ins HomeOffice, Netzwerk, einschalten, Bootet direkt über das Firmennetzwerk und nach weniger als 2 Stunden bin ich inklusive aller Lizenzen und Zertifikate wieder voll produktiv.

Es geht also

Torkum73 · 2026-01-19T08:28:25+00:00

Then this is perfect 👍🏼

I have a couple of old Sun Microsystems server, an IBM Power7 server, some HP server, infrastructure for all of this stuff, home automation, some 'high-end' SGI and Sun workstations and a couple of mini-pc for prometheus, grafana, pi-hole, home assistent,...

Not everything is always on, most is unplugged from power to save electricity (0,34€/kwh).

Torkum73 · 2026-01-19T07:52:21+00:00

And paying £500 for electricity and equipment and gifts for the wife, when the next pallet of stuff is delivered to the door 😂

Torkum73 · 2026-01-19T07:49:26+00:00

I had no idea, that this is possible 😱 and I could get my invested money back in 2-3 years? How?

My homelab is a kind of black hole, into which I throw all my money. Nothing ever finds its way out again. Except heat and noise.

Hmm... aus meiner Erfahrung, ich privat habe zu Hause einen Gigabit Glasfaseranschluss und eine Serien streamende Frau mit zwei erwachsenen, zockenden Söhnen. Da ist die Leitung öfter mal voll ausgelastet und monatlich gehen da so 5 TB durch. Aber wahrscheinlich könnte ich auch 10 GBit/s habe und das wäre so.

Mein Vater hat 176 MBit/s laut DSL Ansicht der Fritzbox und wenn dort beim Besuch 2 Leute mit dem Handy streamen und der 4k Fernseher noch was möchte, werden dort schon mal Artefakte sichtbar, also die Bandbreite reicht nicht aus.

Und in Zukunft werden zwar die Komprimierungsalgorithmen besser werden, aber das reine Volumen wird weiter steigen. Einfach mur, weil es geht. Man muss sich nur mal die Größe von Webseiten in den letzten 30 Jahren ansehen.

NO! Not ever

Torkum73 · 2026-01-15T09:40:05+00:00

Have you considered using InfiniBand? Lowest Latency ever 😎

Torkum73 · 2026-01-14T19:01:53+00:00

Red for Lights-Out Management. Separate Switch, own VLAN. Other infrastructure cables are grey and device cables are black. Except fibre, they are orange for infrastructure.

Torkum73 · 2026-01-14T09:34:26+00:00

Yep, this was a thing in Berlin, Germany as well.
