Hello Legends,

I have a QNAP NAS which I run Immich, Jellyfin and Nextcloud on. This is my first Machine that I’ve had for roughly a year where I’ve learnt all my knowledge.

I have had a couple of mates ask me to build them a server to do the same thing.

My post today is to look for suggestions on a reasonable “budget” DIY build or perhaps a pre-built. Probably just a 2-bay system that will probably be a set and forget system. I’m leaning towards DIY as I for see myself building a new NAS in the future as I am loving discovering and learning more.

Cheers everyone!

This is not based on any study or proper research, just a trend I noticed scrolling through this subreddit and other forums. Is there a reason to go 6-wide rather than 8-wide or any other width? Is it just because people more commonly have cases with multiples-of-6 bays, and that's what is most convenient for them, or is there a ZFS reason?

The most common argument I found was that people claim 8-wide VDEVs take longer to resilver in the event of a drive failure, but from my tests I saw the opposite. 8-wide VDEVs have higher sequential performance, so resilvers go faster (you might have more data due to higher capacity tho)

For anyone curious, link to spreadsheet with my testing results.

Short summary, 8-wide VDEVs have:

• Higher capacity (more data drives)
• Higher efficiency (70-75% vs 66%, depending on ashift)
• Higher sequential read / write
• Same 4K random read / write

6-Wide VDEVs only seem to make sense if you are limited by how many drive bays you have, or by budget. Otherwise 8-wide appear to simply be better, hence why I am confused by 6-wide being so much more common. Are there any other reasons I am missing? Am I maybe completely wrong and just haven't seen or noticed the 8-wide ones?

I'm aware many people suggest striped mirrors, but my use case is bulk storage of random stuff. If I need performance, I'll get an SSD pool.

I have a few nodes that have dual 2.5g interfaces. I have setup vPro AMT in the BIOS and set a static IP. When I boot the hosts the vpro static ip is pingable, then when the interface for the server comes up the AMT interface is no longer pingable.

How does vPro work with interfaces? Is it available to just one physical NIC or both or is it a virtual thing? Maybe Im missing something on how to set this up. For reference I have an MS-01, couple P360 Ultras and a CWWK Q670 and they all have vPro. Im used to IPMI so this confuses me a little. Ive tried to find vidios or docs with more detail but havent had much luck.

Hello all!

I have this LG 25UM65-P, a 25" inch, ultrawide screen that I wanted to put in a picture frame a few years ago. So I removed it from its casing and of course threw it away. Plan has gone to the Magnificent Book of Forgotten Failures and since then, the panel has been patiently awaiting some new purpose.

I have been thinking long and hard how to make it useful again but because of its size, it is quite difficult to actually come up with any useful ideas.

Therefore, I am looking forward to be inspired by you.

Thank you in advance!

I have the following items:
- HPE DL360 Gen 10 Server
- IBM LSI Logic SAS9201-8i

Will these two work together? Generally, are the branded LSI cards just LSI cards with a sticker, or do the OEMs do something to them to make them only work, or only work reliably, with their own servers?

hello

i have a 150 mbit internet connection and i would like to get the same internet via unifi dish somewhere else.

otherwise i have to pay for a 2nd internet connection.

but i was wondering is this one worth it and what speeds can it handle ?

I'm planning to test several SIEM/XDR/IDS solutions in my homelab, including Wazuh, Graylog, AlienVault OSSIM, and Security Onion. I'm seeking opinions on which one I should prioritize for initial setup, considering their suitability for a small homelab environment. While I intend to eventually try

I have a lot of gear that I want to run but it is noisy and I don't need to run it all the time. My idea is to get a Ford E-series van and put in some 4 post racks inside of it, and see what kind of DC inverter I could get, if that is even possible?

Is there any kind of 12v data center "bus" that I would use to bypass having to convert to AC and then back to DC, and simply plug mainboards into the car's 12 volt system?

My goal is to build a utility van that can have a mobile hotspot, and a whole bunch of gear to go on site and do intrusion detection, etc for clients.

Has anyone built something like this?

It is a Buffalo DriveStation™ Duo USB 3.0 (HD-WLU3R1) they got rid of it after a drive failure after it failed to replicate. They were going to trash it and I took it after being offered and upgraded the firmware (which listed the fix but the SysAdm was lazy) Bug Fixes: - Fixed the issue where HD-WLU3/R1 or HD-WHU3/R1 did not boot properly when the hard drive failed. I replaced the drives. Currently have 2x WD Red Plus 3TB NAS Hard Disk Drive, CMR, 128MB Cache, 3.5 Inch running RAID 1. I mainly use it for backups. Is it better to have HDD or SSD for basically cold storage?

I finally got tired of dealing with IPMI fan control behavior, not having a way to easily control fan speeds based on drive temperatures, etc., so I made my own fan controller. Note: This is not an ad, I'm not selling these, I just made it for myself.

It has 4 independent fan outputs (can use splitters to drive multiple fans off of one port) and 4 independent temperature sensor inputs. Each fan can be run off of its own PID controller based on one of the temperature sensor inputs, or it can run off of its own PID controller based on a user-provided temperature (from sensors, smartctl, etc), or it can be slaved to one of the other fans (always run at 60% of fan 2's speed, etc), or it can run at a fixed duty cycle.

Settings are saved in flash and restored on boot, and they can be overridden (either volatile or non-volatile) by the user over an FTDI USB-UART. It also has a built-in watchdog, so for example the user could set it to PID control using user-provided temperatures from smartctl, and if the OS or the user software locks up and stops providing temperatures and resetting the WDT for whatever reason, the fan controller will reboot and reload the config from flash, which can be set to something like a fixed 80% duty cycle.

I've had it installed in my server for a couple months now and it's been working great. It's maintaining the temperature of my U.3 SSD on a PCIe adapter (two Noctua fans mounted to a PCI bracket below it blowing directly onto the SSD, plus a case fan at the front of the chassis bringing fresh air in and slaved to 50% of the Noctua duty cycle). It's all self-contained using a thermistor mounted to the SSD, so it doesn't need any comm input or commands, I only have the USB attached to gather telemetry for integration into Prometheus/Grafana and to change settings if desired.

Let me know what you think!
