does anyone know what the differences are between the cse846 and the sc846?

Thank you so much! It safed me a lot of time. Very easy to follow!

Best tutorial regarding these newbie trap pcie card! wish every tutorial on yt was like this

Mikrotik devices are such a gem. Created in Europe instead of China, OS that supports nearly anything you might imagine, high reliability 😍

Hi bro can you please create a step by step tutorial on setting up pfsense OpenVPN with split tunnelling configuration & also configure vpn client on Ubuntu . Please consider this as a request

Excellent video. I wish you could prepare a VLAN setup tutorial for the Mikrotik CRS309. Even better, with Proxmox as an example 🥰

got 3 730, 3 720 ,3 710, 1 630, 400 forgot the exact model for 1000€ got lucky

You neglected to mention/list the Dell PN for the fan, or Optiplex models either or would be handy for the lazy masses on the interwebs ;) (also damn you for making me wanna get one of these & retire my MD1200's)

Why not noctua or bequiet?

Does a Olt increase your internet speeds that one from ubiquti Olt Fiber xgs xg g gpon olt

Please note : Server PSUs idle at higher wattage than ATX PSUs even if they are more efficient at higher loads. My PWS-1K66P-1R 1600W psu idles at 0.25Amps. And my Antec 1000W HCG idles at 0.09Amps.

These server chassis are so silly. All that airflow and then the output at the back is 95% blocked. No wonder the fans need so much static pressure and rpm. and 40c is way too hot for HHDs running 24/7. That's 104F!

6:30 power supplies are usually most efficient around 50% load, so using a power supply with double the wattage as what you need is often best.

Does networking increase your internet speeds

not a terrible efficient psu and sas expanders.

Investor here ... How do you tech guys feel about supermicro and their products ?

As an admin who managed, many systems with these shelves. I can recommend labelling the front of the caddies with the drive serial number (or wwn) to make it easier to find dead disks!

Bandwith

The "SQ" (Super Quiet) Titanium power supplies are where its at PWS-1K28P-SQ I believe is the right one for these chassis

👍super perfect

Awesome video, great in detail about the 847 case and thanks for the fan info, as this was something i gave up on way back. Stacked 4 of these in my basement rack and together they sound like a jet engine idling. When it comes to PSU, there is a reason for the 1K41 as this with 45 drives will use <75% of the actual capacity of the PSU, meaning more efficient and longer lasting PSU. Heat will always be an issue, but even worse if using SED drives that constantly monitor them selves (have some i got cheap). Tried to block the holes on the side of the 847 case, to force the fans to pull cold air through the front drives/backplane, but i could hear the fans were struggling with my "great" invention. Looking forward for more informative videos.

So the band with is bandwith 100 gig

That's one hell of a Linux iso collection ❤😂

Yeah man those things are loud as balls. I have a Nimble Storage ES1, basically rebadged Supermicro 16-bay, which is a smaller version, and I swapped the PSUs with the Supermicro PWS-920P-SQ . They are platinum, $30 apiece when I bought them, and much quieter than the ones that came with mine, which I believe is the same as that bronze PSU you're running. If you're looking into Supermicro PSUs, be aware that they have at least two different connectors. At first I bought the PWS-1K28P-SQ, and the connector did not fit at all. I'm not sure how many different types they have, but those are the only two I tried. At any rate, congrats on the score! They are very nice enclosures minus the noise.

This was very informative for someone who wants to buy something like this.

Watts, watts, and power. Thanks for the review.

love your vids for homelab guidance. keep it up!

I made a similar transition a few years ago but I moved to 4 x 847E1C-R1K28JBOD. Having SAS3 is great for the future and the IPMI is way more clutch than I realized it would be. I love the density of these 45 drive units. Nice snag and upgrade!

Good run down. Those are some very good deals.

So I am curious why is it only 45 drives instead of 48 drives and I would be interested in seeing what the drive trays look like I know I have seen net app jbods with 48 drives in there with 24 slots and each slot capable on doing 2 drives

We put X10 Supermicro boards with dead sockets but still working IPMI into these. This way you can set fan speeds manually or automatically (optimal) via BMC.The JBOD boards can't do that.

is there a sas3 version of this chassis/expander/backplanes? I suspect that with 45 drives or more you'll start running into bandwidth issues (particularly if you start loading them up with sata ssd's instead of hard drives)

Still think that Chia is promising? I shut down all but a few drives as at current price, it's not profitable given power rates in my area.

You might check for the sq psu models if the noise is too high. Supermicro made those and they are much quieter. They also made a green fan for the wall version that was quieter also. I used those in an sc846 and it helped noise a lot.

SysAdmin woke up and chose jbods 🎉

Supermicro CSE-847 Case... ebay.us/H8p4nY (not where I bought mine, but is a great source) (affiliate links)

How much band-with total Mikrotik CRS504-4XQ-IN

Excellent video

Great video with a perfectly detailed explanation. Cheers!

doing a sstorj myself; sql lite on ssd; hdds for the data itself; all are zfs pools all over the place; the data one is one parity Z1 or DRAID1. special vdevs on SSd also. full gigabit full duplex. 5ms to london. will see. i will only recuperate my investment in probably like 5 years but is fun work. learning lots.

0:41 IT = Initiator Target

Just landed on this page, enjoyed the video, although CSE847 (jbod 45) would be a better choice as this has 7 fans and 2x 1400w PSU. Anyway, your heating issue on the 16 drives is due to your placement, your blocking the airflow, turn the disks by 90 degrees and you will have a better airflow.

Thank you

Did you break even?

I am still using the 1U Supermicro pfSense build you first made a video about. It works great.

Great video I also try to avoid copper when it comes to 10g networking due to heat I have a few RJ45 based 10g nics I don't even use them because of the temps. I'm currently moving all of my services from ESXI over to Proxmox so I'm definitely in the market for a 10g switch.

Wireguard, it's 2025.. 😀

Where is affiliated links?

another great video. i use to use openvpn on pfsense, but now i use tailscale in pfsense. bypass all the this setup. much easier setup.

hey bro，use pfsense Means your data will trans to your home server first?
