Der Bauknecht Support hat mir zwar geholfen meine Spülmaschine endlich reliably ans Laufen zu bringen (der Abwasserschlauch muss aus Gründen auf eine gewisse Höhe geführt werden), jedoch ist deren Callcenter Dienstleister echt das Allerletzte.
Wenn ich nicht selbst dort angerufen hätte könnte ich meinen mit Telefonbetrügern gesprochen zu haben. Das Playbook und das ständige Andrehen von Zusatzleistungen und Einschüchtern ist echt wild.
Fedi, someone on Reddit solved the mystery with the two stacked fans in this #storage.
It's called a "counter rotating stacks".
Basically two fans rotating in opposing direction (with fins also pointing in opposing directions).
It's used to increase the pressure. So the hunch of it being for increasing the pressure was right.
However what was also correct is that if they were two identical fans it wouldn't do anything (except redundancy maybe).
SATA/SAS disk naming in #Linux really is kinda stupid, isn't it?
This mainboard has 2x SATA + 2x SAS (with a to 4x SATA splitter cable attached each).
How does the system choose to name the drives?
/dev/sda is 1 of one of the SAS ports.
/dev/sdb, sdc, sdd, sde are the 4 drives from the OTHER SAS port.
/dev/sdf, sdg, sdh are the remaining three of the first SAS port.
Why?!?
