I prefer sata: if I retire a fileserver I can reuse the hdd in another system or a usb enclosure easilly. For sas I haven't seen an usb enclosure yet... Sas hdds/ssd are always dataceneter oriented devices; they have fast reponses when errors occur using the fail-fast approach Sata hdds/ssds...

It's always funny to read about Infiniband and its history, that it was supposed to be the successor to pci (and agp if you remember :)) but instead became "just" a networking technology used in hpc/supercomputers. Many of the original ideas for infiniband became reality with PCIE and CXL :D As...

What ist "Lights Out Management"? BMC/ipmi?

Xeon E5 1620 V4 Currently yes. In it's prime it ran different services like universal media server, plex, web & postgres servers.

When that board came around sata ssds were the "norm". If you check the mainboard you will see two yellow/orange sata ports; these are powered sata ports that can take a sata dom (=ssd) :D Btw I have a x10srl in my second fileserver (836 filled with 6TB hdds :D), it's still going strong...

If you need "just" 48 ports and can live with 30w poe per port there are other models from the 7 series 7150-48p: 1gbe, 12x 30watt per port, rest 15w per port 7250-48p: 1gbe, 24x 30watt per port, rest 15w per port 7450-48p: 1gbe, 8x 90watt per port, 40x 30watt per port (required both psus) The...

Before you start to replace fans: what heatsink (+ cpu + mainboard) do you plan to use? I use an active heatsink on a (I think) 225w tdp epyc cpu with the airshroud and it helpts to keep the fans reasonably quit/loud. With passive heatsinks the midwall and rear fans will rotate faster to push...

This switch gets hot even with 1x orignal fan & psu. I believe if you get it to "acceptable" noise levels you will fry the system in no time...

This reminded me of CVE-2020-19909 :D (curl vulnerability rated with 9.8 on a scale with 10 being the worst) https://daniel.haxx.se/blog/2023/08/26/cve-2020-19909-is-everything-that-is-wrong-with-cves/

Noctua has different fans, I think the industrial fans with 3k rpm are quite capable (120 & 140mm) but then again they are not silent :D

That's one of the reasons why you can't buy a pack of gum and pay with your credit/ec/giro(debit card in Germany in many Places. The old nixdorf machines still work and the owners can't be bothered to update/replace it with a system that would add more features/allow to pay with modern methods...

I can't agree... My supermicro 836, 846 and 745 are pretty easy to open/service. Short cables will be a problem if you want to pull the server out of the rack, but I think this is a selfmade problem... (I'm using 0.5-1M qsfp28 cables for my servers and I have to remove them to pull the server...

define "normal" cases :D I have 3 big towers, all from Lian-Li and with different sizes. With rackmount you have more prefictable sizes: width is always 17.75" wide or high (19" with rackmount ear/rails/etc.) and a multiple of 1U in height (or width) with usually a max depth of 90 cm. I prefer...

The 846 is a really great chassis, especially if it's a "B" or newer version (support for two ssds in the rear and I think a few more mounting points for mainboards): the pdb can be swapped to support newer and more efficient power supplies, there are sas3 expander or sas3 expander + 8x nvme...
