If it prevents us having another crappy week thanks to the like of Crowdstrike, good.

Other have answered the runtime and load question very well already.

I have three other points.

1. Batteries degrade over time. Over-speccing your UPS means more likelyhood that things will hold up in three years time as the capacity given is for new ones. Plus, not running your UPS at 100% capacity reduces its stress. Again, more reliable.

2. You can get a much better quality UPS by buying a second hand one without batteries off ebay and replacing them yourself, typically for a fraction of the cost of buying new. Plus you know you have new batteries. UPS is something where quality genuinely matters. I’ve had to carry a cheap and badly made UPS out of an office whilst it was on fire, so now I spec more carefully. (And ensure they’re metal bodied!)

3. Consider what you NEED to power. What sort of power cuts are you expecting? Does it matter if something goes down?

I UPS my servers and my main desktop, but not my routers, nor my wifi or IOT things. My internet provider also goes out when there’s a cut (I’m on a mesh system so rely on neighbours, who will typically also be down) and I can’t do much without power anyway, but it keeps the disks spinning. We typically get very short automated outages here of less than 10s (yesterday was a bad day, we had 9 within 2 hours)

Because Musk has turned it into somewhere that hate speech is not only tolerated, but encouraged.

Lemmy is literally the antithesis of X, no wonder you’re being downvoted.

Why are you cross posting content from a hate site to lemmy?

What a rubbish article. Complete non-story.

Whatever you use, don’t build it to a definitive target.

From personal experience, which may not be universal: No matter how carefully you plan this, your needs will change sooner than you think. Expect to re-organise things things, make changes constantly, and occasionally deal with messes you made. We do this to tinker and play and experiment, and that creates mess.

So design something you can change. Luckily, that is what racks are about anyway, but do stuff like having space behind it for an extra coil of cable, space between servers, a shelf or two for those annoying random things, ability to extend. Space around it to work and move (don’t fix it to a wall in such a way that you can’t reach it all - wheels are good together with enough cable flex to be able to easily pull the rack out so it doesn’t go Whoo… as everything suddenly powers down)

Obviously some rules are hard-baked, like “heavy stuff at the bottom”, but be fluid.

A perfect use for them - controlled environment, difficult conditions, repetitive and predictable workflow.

But I’m puzzled by the design - why have a cab? Wouldn’t a more efficient layout be a whole-bed platform with all systems underneath?
