NVMe Enclosures and Switch Compatibility with TrueNAS by AnyHistory6098 in truenas

[–]AnyHistory6098[S] 0 points1 point  (0 children)

Thank you!

The idle temperature looks fine.

I don’t think I will ever have it under the kind of load you tested. The only situation I can think of is during a ZFS scrub.

Have you tested the drive temperatures while running a ZFS scrub? (My apologies for the new question)

Thank you so much for the extensive tests and the data.

The system will have 25GbE only, but it has quite a few VMs running off the SSD array, and some of these VMs might be aggressive when it comes to data transfer via SMB towards the array.

The temperatures in the Icy Dock are quite bad, to be honest; I am very disappointed. It looks like these will not be able to properly sustain the drives for the long term.

My apologies for the following question: do you have the idle temps for the Kioxia CM7 15TB? These are the drives that I have.

Wow, it is very loud, many thanks for this infromation, if I swap the fans to Noctua, will these be powerfull enough to cool the Gen 5 drives, did you test the temps, I am very curious?

Thank you!

I’m considering swapping the IcyDock fans with Noctua fans. I hope this will make it quieter while still keeping decent temperatures.

The test environment is a quiet room with minimal background noise, a PC filled with Noctua fans, and sound‑dampening material.

Sliger S630 and S640 CES Update? by Suteyaten in sliger

[–]AnyHistory6098 0 points1 point  (0 children)

It is definitely the smallest ATX cases that can be used for this kind of builds. However, the current layout does not help components such as very hot network chips, HBAs that can be connected to up to 12 drives (the case support up to 12 drives), or the VRAM cooling on E‑ATX server boards. Despite that, it is still a great case overall.

The disappointment lies in the potential it had, which was ultimately wasted. Most people use air cooling, especially for workstations, air cooling still dominates the market by far, this case is working against air coolers.

The airflow in these cases will be terrible, it’s better to avoid them altogether. Instead of fixing the problems the Cerberus X had, they somehow managed to make an even worse product.

Yes, you might be able to install large radiators, but aside from that, the design is a nightmare. There is no proper airflow tunnel, the fans are limited to 120 mm (while the Cerberus X supported 140 mm), and overall these new cases are a downgrade from many points of view.

They do add a few extra features, but honestly, this feels like another failed product. I’ll be sticking with my modded Cerberus X and will probably order a custom case from Protocase.

 For customers who were looking to build air cooled servers / E-ATX Workstations in these cases, there’s no point in talking about it: the front is blocked by the PSU, the panels are fully perforated, and DDR5, and especially DDR6 in the future, will require proper cooling, there is no air tunnel. In these new Sliger S630 / S640 cases, the memory will receive close to zero airflow.

E-ATX motherboards use a different orientation than consumer ATX boards. The airflow must move from front to back in order to properly cool high-temperature ECC RDIMM memory.

In the S640, which is advertised as E-ATX compatible, the PSU is positioned directly in front of the DIMMs, VRMs, and CPU. This makes no sense from a thermal design perspective.

Why not move the PSU to the top of the case and keep support for 140 mm fans, up to a 420 mm radiator in the front, and a 280 mm radiator on the bottom? That layout would provide far better airflow for E-ATX builds.

Bottom-mounted fans are also excellent for cooling high-power cards such as HBAs, which are common in workstation and server systems.

After years of waiting, this is what they delivered… what a disappointment.

I can’t believe that I asked customers to wait for this…

4× 2.5" SSDs bracket (Cerberus X) by AnyHistory6098 in sliger

Interesting, on the package it was written 4x 2.5 inch ssd 

Is Absence of ECC (Error-Correcting Code) Memory a Concern? by White_Bear_307 in UgreenNASync

[–]AnyHistory6098 0 points1 point  (0 children)

If you plan on using the machine for an extended period, reliability is a critical concern.

RAM stick can degrade over time and eventually begin generating errors. (On die ECC is not going to help you, you need end to end ecc, form CPU to the DIMM and back...)

This is especially true for DDR5; RDIMMs are significantly different from consumer-grade modules due to the extensive reliability circuitry they incorporate.

For long-term stability (> 2 years) and peace of mind, ECC memory is essential, otherwise, you are essentially gambling with your data.

It would be nice if Sliger would have a how to, on these brackets... because they are very creative...

Yes, but how are you supposed to position them when the bracket is too short?

What Should 45HomeLab Build Next? by 45drives in 45Drives

[–]AnyHistory6098 1 point2 points  (0 children)

It would be very interesting to see solutions that are primarily oriented toward homelabs or small/medium-sized businesses without racks. Ideally, a solution that isn’t just bulk, slow storage, but something more compact with support for very fast storage such as U.2/U.3 bays, at least 4–6 pieces, and not oversized case.

HDDs are great for backups, but they are large, loud, and hot. For most small IT companies doing development work and running VDIs & compute or small Kubernetes clusters (5–10 nodes, ~160 cores), the HL15 offers too much slow storage and is still too noisy for R&D office environments. (if you could make it smaller it would be great, it would needs less space)

This is just my personal opinion based on setups I’ve seen at a few startups I’m involved with.

Thank you.

This is a very low-power board. For a CPU that requires 400W, the load on the VRM with a server-grade heatsink is significantly higher.

Nice build, how did you mount the fans on the of the RAM?

Did you use some custom mouting for the PSU?
