Be nice. Assume others have good intent (within reason).

Block or ignore posts, comments, and users that irritate you in some way rather than engaging. Report if they are actually breaking community rules.

Use content warnings and/or mark as NSFW when appropriate. Most posts with content warnings likely need to be marked NSFW.

Most 196 posts are memes, shitposts, cute images, or even just recent things that happened, etc. There is no real theme, but try to avoid posts that are very inflammatory, offensive, very low quality, or very "off topic".

Bigotry is not allowed, this includes (but is not limited to): Homophobia, Transphobia, Racism, Sexism, Abelism, Classism, or discrimination based on things like Ethnicity, Nationality, Language, or Religion.

Avoid shilling for corporations, posting advertisements, or promoting exploitation of workers.

Proselytization, support, or defense of authoritarianism is not welcome. This includes but is not limited to: imperialism, nationalism, genocide denial, ethnic or racial supremacy, fascism, Nazism, Marxism-Leninism, Maoism, etc.

Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

Plot twist: they're 256MB drives from 2002 and total.. 61.44GB. Still impressive, nvm. If they were the largest available currently (36TB) they'd total 8.64PB

[–] thisbenzingring@lemmy.sdf.org 20 points 1 day ago (2 children)

that array is a POS. Changing failed drives in that would be a major pain in the ass... and the way it doesn't disapate heat, those drives probably failed pretty regularly.

[–] EtherWhack@lemmy.world 10 points 1 day ago

JBODS like those are actually pretty common in data centers though and are popular with cold storage configs that don't keep drives spun up unless needed.

For the cooling, they usually use the pressure gradient between what're called cold and hot aisles to force air through the server racks. The pressure also tends to be strong enough that passive cooling can be used and any fans on the hardware would be more used to just direct the airflow.

If you're paying per U of rack space for colocation then maximizing the storage density is going to be a bigger priority than ease of maintenance, especially since there should be multiple layers of redundancy involved here.

[–] thisbenzingring@lemmy.sdf.org 9 points 1 day ago (1 children)

you still have to replace failed drives, this design is poor.

I work in a datacenter that has many drive arrays, my main storage space direct array has 900TB with redundancy. I have been pulling old arrays out and even some of the older ones are better then this if they have front loading drives cages.

there is no airflow gaps in that thing... I bet the heat it generates is massive

[–] Agent641@lemmy.world 3 points 1 day ago (1 children)

They probably wait for like 20%of the drives in an array to fail before taking it offline and swapping them all out.

Also, this doesn't sound like the architects problem, sounds like the techs problem 🤷

[–] thisbenzingring@lemmy.sdf.org 2 points 23 hours ago

I work in a datacenter as the system admin and waiting after one drive fails for a second to fail is asking for disaster

[–] BadJojo@lemmy.blahaj.zone 9 points 1 day ago (2 children)

The interface is SATA, not EIDE or SCSI, so I'm going to guess 2TB minimum but I'd bet they are more than likely 8TB drives.

[–] Lyra_Lycan@lemmy.blahaj.zone 3 points 1 day ago

You're right - I found the source. Turns out they're 8TB SAS, for a total of 1.92PB.

looks like SAS to me

[–] Lyra_Lycan@lemmy.blahaj.zone 2 points 1 day ago

I guessed they were SATA. If that is the case, here is one such 36TB SATA HDD. Apparently Seagate make these in SAS models as well

[–] Ging@anarchist.nexus 5 points 1 day ago (2 children)

This is a helluva range, do any wizards have a best guess at how much total disk space we're looking at here?

[–] sad_detective_man@sopuli.xyz 7 points 1 day ago* (last edited 1 day ago)

Can't make out the size of the drives but they're HDD and there's 240 of them.

Multiply that by what size HDD's are available in the year you think this video was taken. Money is on 1 or 2 tb? Those are bulky as fuck though so they could be as little as 100 something GB, but then I think we'd be looking at a lot more piss-yellow plastic

That's such an unfathomable about of storage -- I'm an old man with 0.2 TB total on my backup of everything Also redlib link for the privacy enjoyers: https://redlib.perennialte.ch/r/computers/comments/od03lz/ever_wondered_what_2_peta_bytes_looks_like/

[–] Lyra_Lycan@lemmy.blahaj.zone 2 points 8 hours ago* (last edited 8 hours ago) (1 children)

Hey, that's a perfectly normal amount of storage. My personal files backup for my partner and I amount to about that much.

[–] Ging@anarchist.nexus 1 points 7 hours ago

No shade in yo direction at all--I'm just amazed how much memory we can cram in handhelds much less these U-racks or whatever they called
