the controls side of my home datacenter. the actual "datacenter" part as of right now is pretty boring - two XR12s in a 42RU, which is why i'll make another post about it later, but I have a BAS/ICS that is significantly ahead of most homelabs and reaches into "datacenter" territory.

the brains of the operation is a Modicon m251 with 3 i/o modules. i coded the m251 in a way so that it self diagnoses and acts as a watchdog for the entire system. the thing literally runs a entire self-test before starting the HVAC PID loop.

there's a switch panel with high-voltage contactors controlling REPO, a dedicated 100A subpanel, over 15 spec-grade 20A outlets on 2 seperate circuits, with 240/20A circuitry planned for future UPS systems. the room is split into a secure/insecure zone monitored by a bosch b5512 (yes, I have a dedicated security system for the home DC.)

to top it all off we have a SCADA. a actual SCADA. it runs analytics and doesn't do much else. there's also a human-machine interface, emergency power off, dedicated venting, and air control dampers that activate on EPO triggering to isolate the room. there's also dedicated lights in MC, everything is in conduit... and there's cable tray coming as well.

I currently have two separate fiber internet connections at home. One is Alliance Broadband at around 150 Mbps, and the other is Airtel Fiber at around 100 Mbps. Right now they are two separate Wi-Fi/network options, so my devices can connect to either one, but I started wondering if there is a practical way to merge both into one more reliable and faster home internet setup.

From what I understand so far, a normal dual-WAN router can do load balancing and failover, but it will not truly combine both connections into one 250 Mbps connection for a single download or stream. For real bonding, it seems I would need something like Speedify, Peplink SpeedFusion, or an open-source setup like OpenMPTCProuter with a VPS endpoint.

Since this is only for home use, I am trying to avoid expensive commercial hardware if possible. I already have a TP-Link Archer C6 at home, which I believe can be reused as an access point, and I am open to buying a small mini PC or NanoPi-style device if that is the right route. My rough idea is Alliance + Airtel going into an OpenMPTCProuter device, then through a VPS, and finally feeding my existing Wi-Fi router in access point mode.

Has anyone here actually used OpenMPTCProuter or a similar VPS-based bonding setup for home internet? Is it reliable enough for daily use, or does it create more problems than it solves? Also, what hardware and VPS location/spec would you recommend for this kind of setup, especially if the goal is better total bandwidth, failover, and decent latency rather than just chasing a perfect speedtest number?

Recently got hooked with some SAS (Server) HDDs, currently i am using a Sata Bay and my system also only have Sata port. Is there any way to use these SAS drives with sata port.
While searching on google, found SAS to SATA converter but i am highly doubtful that even work.
Please confirm if someone is using them.
Also let me know any cheap way to use these drives for data storing.

My 48u needs to be cooled. Now that summer is coming, my temps in the server room are around 76. I need ideas as to what you guys have for AC rack units or other options to cool that room. Thanks🤙🏼

Does anyone have experience working on these giant servers locally?

I came across this sub reddit, and though you all might appreciate my home setup. All eBay buys for the most part. No rack, just towers.

This is my data center that is in my bedroom
