its not likely that Sas expander 82885T (lenovo) is locked to a lenovo firmware or hardware or something. i read a thread on reddit of a guy using the lenovo brand Adaptec Expander, and says it seems fine. i dont know im just being weary im about to buy 5 of them. another quick question i have...

And the reason for the choice in controller is because I kind of believe that controller generation, IOPS capability and throughput kind of determine reliability. At the start I was thinking of using a cheapy LSI pcie 3.0 watever. But in the past, in first gen i7 (nehalem) days I had a sata...

But thanks for telling me your idea of how to negotiate the the SAS3 lanes. I was going to send all 16 lanes over to the other chassis, but use 16 drives worth of allocation from the 2 expanders sending across 16 lanes. I believe "drive allocation is handled by the last Adaptec expander In The...

This is quite good advice, and is kind of the idea. The reason I didn't go Nas device to begin with was the cost. Nas devices cost alot of money to buy, and I don't know why. But going with AMD I can get a fairly good level of power saving. Around 200 watts on a 16 drive storage array. As for...

i know everyone says its gonna suck to wire it all, but i dont belive so, i have ideas for the wiring, labeling and stuff like. and i think its gonna be fun to know the build back to front myself.

the case is a thermaltake wp200. the top part, with a motherboard installed on one side, has the capacicity of 70 drives, 5x 14drive sleds. the bottom has capacity for only 20 drives, with a PSU in there with them. witouth psu its 24, but im putting the controiller and a standalone psu in the...

4 of the mini SAS connections on the 82885T are not for hard drives, I wrote that above. According to thea manual 1-5 are for HDD only. The rest are for linkage. I have 2 cases/chassis. 1 of them will be capped at 16 Drives. To get as many mini SAS lanes as I can from the 16 drive case to the...

Yeah so I think I'm gonna scrap the multi controller card idea and run it off pcie 4.0 riser cables from the PC 4.0 8x slot. And then power some expanders wherever I need them. Solves heaps of headaches I was trying too figure out by re-directing pcie lanes from nVME etc. You guys have helped...

Ok, I think I've worked out a solution. My controller device is 16gbps (pcie 4.0 8x). I'll use 2 of those cables you linked above and connect too 2, SAS expanders Then via the external ports on the SAS expanders i'll route too another 2 SAS expanders in the second top half of the chassis to...

Ok I'm learning new things here. After I connect 2 SAS expanders I only have 20 internal drives left on those cards. But I'm pretty sure I can chain SAS expanders off each other? Or am I wrong in assuming this?

I do know that, but I can't find an Adaptec pcie 4.0, SAS 24gbps SAS expander. Will any brand negotiate with it?

Doing some more diligent research it seems Micro Sata Cables offers the most reliable looking solution for this NVME to PCIE case. https://www.microsatacables.com/m-2-m-key-pcie-gen4-with-redriver-to-oculink-4i-sff-8612-adapter#:~:text=The%20M.,the%20capabilities%20of%20their%20system. im...

7900X3D on a X670E strix. Currently getting by on the Asus tuf X670E. The tuf is ok it has 2 pcie 4.0 4x slots. The strix has an extra 5.0 8x slot + a 4.0 4x slot. So if this nVME adaptor shenanigans can't be achieved I'll have to buy the strix and sell the tuf. If you don't need the memory...

Hi, happy new year! im building an AM5 workstation/server/Lan rig. the main use of the build will be a Raid 6 Hardware array. comprised of 16, 16tb drives on an Adaptec 3254-16i Sas Controller. a grfx card with HDMI 2.1, and some ECC memory. On windows :p AM5 is undeniably fast. Multi core...
