I use the airshroud in my 836 and 846 in combination with active heatsinksAs far as the MB compartment, 2U's seem to be easier to cool than 4U MB compartments since the 2U height seems to help keep airflow focused over the MB components.
Yep, air shrouds work too! I too use Supermicro active heatsinks in 2U chassis, helps keep things nice and quiet!I use the airshroud in my 836 and 846 in combination with active heatsinks
I don't know where they all went... They were few and far between for a while and now they seem to be almost nonexistent.I see there are a few 846s on ebay and they are quite expensive ($650+)
I understand 846s very much preferred as nas servers but isn't this kind of extreme? Is this all because full size expansion slots?
Sadly, I needed the height.Glad I grabbed a few 846 a few years ago they weren't "cheap" ever though, just more avaialble and maybe 100-200$ less than they are now.
That's a lot of money but its' not $1000 more like buying new kind of thing
Personally, unless I needed the height I'd go 847 that takes a motherboard.
Then you can run 4x NVME on the backside with the other backplane that does 4x nvme the rest sas\sata.
That's my gameplan at least
BPN-SAS3-846EL1-N8 can be obtained from supermicro through resellers, they seem to have them a little more available. However they are 800+ euro.BPN-SAS3-826EL1-N4
In a 836 or 846, 100%. Not quite that simple with only 2U in an 847, that’s where the 9305 is useful, the 3008 based stuff works, but only 8i rather than 16/24i.9305s are a bait IMO. Cheaper to get a 9300 and an expander.
You can get low-profile expanders like the 82885T. Kind of a pain to route the cables if you have it right up against another card, but still doable.In a 836 or 846, 100%.

There hasn't been a new one in a while (though there are third party clones), but there isn't really anything obsolete about it. Spinning rust doesn't need 24G SAS. Officially, it's only available with 4+8 NVMe slots, but if you can track down an -N12 backplane, you can have all 2 rear drive slots support NVMe. But that being said, if you really need that much NVMe, you're better off with an SFF chassis anyway.Well I got CSE-847 (sas3 backplane with 2 2.5" caddies) and then another CSE-846. The dilemma is I have no good use for them and not sure if I should sell one of them or keep on chugging them around
So is 847 the last of its type?
