Horatius Bonar posted:You can cut (or split) 3 1/2" thick rockwool approximately down the middle with a bread knife and get two pieces that will about fill your 2". But then you'll see what I mean about it not being good exposed. Too narrow means you need to stack a few, across or beside eachother and cut to size to fill the cavity. Yeah if I can't figure out someplace to get the size I need, this is probably what I'll end up doing. Vim Fuego posted:Post a pic of this cockamamie setup. Also, doesn't computer equipment usually have airflow instead of insulation because it needs cooling to keep working? There's nothing particularly cockamamie about it, this is a very common style of rack. There's about 2 inches of open space behind the door, and the uprights are adjustable so I can increase that a bit if I need to. The holes in the mesh panel are just a shade over 3.5mm, so a #6 screw will fit through them. Most datacenters use under-floor cold air ventilation, so the bottom of the rack is open, and I have an air handler unit that will pull air from underneath the rack and push it up over the front of the servers. I'll have to seal up the bottom around the fan intake, and I have a few ideas for how to do that. Soundproof server racks are not unusual, they're just very expensive, and I'm trying to make something functional out of what I've already got.

Liquid-cooled servers are becoming more popular for a lot of reasons having nothing to do with noise, but hopefully they'll proliferate and turbonerds like me will one day not have to choose between having nice servers and having eardrums.

fatman1683 posted:Most datacenters use under-floor cold air ventilation, so the bottom of the rack is open, and I have an air handler unit that will pull air from underneath the rack and push it up over the front of the servers. This is not true, and in a way that may significantly impact your plans. Datacenters do usually push cold air through raised floors, however it doesn't come up under the racks. Instead, whole aisles of rack are face-to-face and cold air is forced up into the aisle between them, then gets pulled through the equipment to the returns in the row behind (back-to-back rows are returns). The cooling system is front to back, not bottom to top. This is significant because of the air volume. That rack doesn't look to have much room for air to get in front of a server (behind is almost always less of an issue), and you're planning to impede the airflow with... Something. It sounds like you're building a makeshift rockwool box to suffocate datacenter equipment inside, if I'm honest.

Plastik posted:This is not true, and in a way that may significantly impact your plans. This is the air handling unit I'm using. It's designed to pull air from under the floor using a duct through a hole cut in the tile. Whether or not this is a smart idea in a datacenter with a proper cold aisle/hot aisle configuration is not relevant to this discussion, but it does direct air from underneath the rack up the front of the rack to the server intakes. It's rated for 3.5kw of cooling, which is way more power than I'll ever have in this rack, so even though that rating is probably based on datacenter intake air temperatures, I suspect I can get away with about half that much thermal load at 'normal' room temperature, and the thickness of the door insulation and the positioning of the forward upright will be such that airflow from the intake is unimpeded from bottom to top. I won't be using the ducting, just letting it pull in air from under the rack through a filter. The top of the rack has an exhaust fan at the back, and the two fans are rated within 10% CFM of each other, so airflow should be pretty balanced. fatman1683 fucked around with this message at 10:54 on Dec 18, 2022 |

If you want quiet gear then answer is to build your own supermicro or whatever and give it nice tower coolers and 120mm fans instead of repurposing 1RU machines from disposals.

My very naive thought was that they accidentally built it too short, so they were using cinderblocks to figure out how it would look like if it were taller, or if they needed to make very long stairs. Then I realized.

~Coxy posted:If you want quiet gear then answer is to build your own supermicro or whatever and give it nice tower coolers and 120mm fans instead of repurposing 1RU machines from disposals. Exactly this. Although, you may not even have to go custom, modern Dell servers run their fans pretty quietly as long as you're not Splicer posted:Lol I bet it's crypto mining and they're trying to make sure their landlord doesn't find out where all the electricity's going. yeah uh welp. But more importantly, silent server racks are expensive for a REASON, and that's that while the soundproofing materials may be cheap, engineering a rack to be quiet outwardly but also channel lots of air properly for cooling is very difficult and expensive. Many of those racks have internal air channels (usually with multiple bends, and all insulated with soundproofing on the inside such that the sound hits those bends and gets absorbed), plus various layers of soundproofing on all sides of the rack, not just the front and back. Any penetrations whatsoever are conduits for air, which is the conduit for sound, so slapping a bunch of soundproofing on the back door is only going to get you a bit of reduction even before you get to putting a SEVENTY DECIBEL fan in the bottom of the rack.  And all your servers will be exhausting air at a solid board 2 inches away - even with some airflow from that 503 cfm fan and some amount of convection movement they're still going to be cooking themselves.I've been where you are, I pondered the silent rack, then I built a custom 1U server with an ASRock board that only requires 45 watts and put Noctua 40mm fans in it. It's not SILENT, but since it's in my low-voltage NEMA enclosure in my hall closet it's quiet enough I can't hear it even with the closet door open (and actually the switch fans, also Noctua, run faster/noisier since that generates more heat). If you want a server with a warranty, get a Dell and don't push its CPU. Also, uh, pretty much all server racks have options for solid doors - I haven't priced them recently but it's probably easier and faster to replace your vented door with a solid one as a start.

Oops heh got caught up in the Server Rack For  hilarity - I actually came here to post, having just finished filling and compacting two fairly small trenches (total about 11 feet long, 1 foot wide, 2.5 feet deep): I consider myself a DIY enthusiast, enjoy learning new things about construction and making things, but you know what? gently caress earth moving. gently caress everything about it. I'm sure it's better and easier with machines (these trenches are very close to the house and connect various electrical things so I didn't want to risk bashing an excavator bucket into a window or the new electrical substructures I've just finished putting in, plus, y'know, the expense), but even so, I'm done with it. Any earthmoving or digging that I need in future, I'm loving calling someone and paying them to make it their problem - what a giant pain in the rear end. And the arms, and the legs, and the core. And it's all clay soil here and currently very wet so it sticks to loving everything. Ugh.On the plus side, my $300 Chinese jackhammer has performed brilliantly for everything I've needed - digging, tamping, breaking up part of the foundation so I could get the conduit to line up with the PVC terminal adapter on the panel  , etc. I'm looking forward to never using it again and hopefully selling it for something near what I bought it for, but thanks China.

wesleywillis posted:Earth moving equipment is pretty fun, but call before you dig. Oh yeah no I had to be very careful because one of the trenches crossed a joint service trench from the original build in the 70s. Except, probably because it was the 70s and no one gave a poo poo, the pipes were literally 12 inches down from grade. Oh, and also, unlike a joint trench today, there was no separation - gas, electric, and PVC sprinkler pipe all physically touching each other for the entire length of their run (forming a triangle with the water on top) and laid a foot down from the surface. Best part is one of the two reasons I was doing these trenches was to reroute that specific electric (a feeder conduit to a subpanel in the backyard), which meant I had to carefully slice through the electric conduit without A) cutting into the wires inside or B) nicking the gas or PVC water pipe  . Couldn't of course use a normal pipe cutter because with the pipes touching I obviously couldn't rotate a cutter around the conduit. That was a ticklish and stressful 30 minutes with a oscillating saw and because it was thickwall rigid conduit not only did it take a long time but I went through two or three $12 blades. Still, though, I'd rather do that cut a thousand times than move more loving earth with a shovel. SyNack Sassimov fucked around with this message at 18:37 on Dec 19, 2022 |
