    Homelab - Mail Relay Server for Cron

    I quickly checked them but they seem to provide only outbound SMTP. I would really like to have also POP/IMAP. Like from my LAN, send an email through the SMTP relay server and store it on the server where it can be accessed. That way I will be able to read notifications all the time (webmail...

    Homelab - Mail Relay Server for Cron

    I used to use Google SMTP server for sending cron notifications in case of faults (e.g. mdadm array broken, smartctl errors, now ZFS, etc) but I am seeing that it's getting more and more unreliable. In the paste i used msmtp to interface directly with the google server wih a gmail account. Now...

    Proxmox VE vs VMWARE ESXi for Windows 10 VM

    Dear all, I know it might be a strange request but please bear with me ... I started using VMWARE ESXi about 5 years ago as my virtualization platform of choice in my home lab. Since then, due to easier backup, scripting and base OS (Debian), I switched to Proxmox VE (without subscription). All...

    Virtualization and ZFS

    Thank you for your replies as usual, _gea. Is there a "zfs set" command to force sync at all times? I'm not so much concerned about performance as I am about consistency. I doubt a SLOG is required if the primary storage is NVME anyway. In Proxmox I disabled Caching options for each virtual...

    Virtualization and ZFS

    I would be interested in your opinion because I am migrating all my machines to Virtualized solutions (mostly Proxmox VE, still have one ESXi Box). For the Host (or AIO using OmniOS + Napp-IT) filesystem I'm without doubt using ZFS. Does it matter the FS that the Guest will be using? Of it...

    PCIE Bifurcation

    I have a crazy request. I have a X9Dri-LN4f+ Motherboard and PCIe bifurcation seems to work just fine (tested with an ASUS Hyper M.2 adapter). My problem is that the GPUs take 2 slots each and then I'm left without any room for other devices. So I'd like to cable using some riser extensions to...

    Supermicro X9SCM-F - Heatsink problems ....

    I found a solution that works for me (Supermicro X10SLL-F, Xeon E3-1270v3 CPU) that I just bought second-hand and came with this CPU backplate (BKT-0028L) installed as well as a Passive Dynatron heatsink. Here is my solution to install a more efficient (and less noisy) cooler on a Motherboard...

    Server needs better cooling - What options?

    Sorry for not replying sooner, I didn't get any new notification :(. Unfortunately that's not the case. I'm renting an apartment and no individual garage. Plus I wouldn't put my server in the laundry room because of humidity. However I noticed that since I moved in this apartment, the walls...

    Server needs better cooling - What options?

    As a side note I should add that these servers will basically be only turned on when needed. Essentially all they will be doing is compiling (DistCC or Icecream clusters). They generate far too much heat to be able to use them all day long. Also the electricity bill suffers :( So I would...

    Server needs better cooling - What options?

    Sorry for not saying before. I live in Switzerland. I can also order things in Germany though (ship them to a friend :)). Oh my god :eek:. So expensive. That's almost 700$ :confused:. And I'm fairly sure here in Switzerland but also probably in Germany it's going to be more expensive than in...

    Server needs better cooling - What options?

    I'm not sure i understand your point about the electrical conductivity. From what I know the heatspreader of the CPU is supposed to be grounded. I assume so since the coolers I know touch the case chassis, and since this is earthed, it wouldn't be a very good idea that the spreader is at...

    Server needs better cooling - What options?

    Yes references to specific products would be great, thanks ;) So every say 6 months you need to change your coolant :confused: ?

    Server needs better cooling - What options?

    Can you provide some more specific references please? I'm a bit against putting both servers on the same cooling circuit because then the electrical wiring will probably get more complicated, right ? Also thermally the last CPU will have much higher water temperature. Series connection of...

    Server needs better cooling - What options?

    Would you have a water cooling configuration in mind ? There don't seem to be many 2011 Narrow/Square ILM water coolers. I think there are adapters for the Corsair H series on eBay but I'm not sure. The problem would be how to get the "pipe" out since it's a closed loop I need to put the whole...

    Server needs better cooling - What options?

    As the title says I did the (probably big) mistake of buying 2 x Supermicro SC825 TQ-R740LPB 2U chassis. One at the moment is equipped with a X9DR3-F (one socket not working, I will probably need to check for bent pins) and the other with a X9DR3-LN4F+ (both sockets working). Both boards are...
