Hey guys, is it ok if I use a LSI HBA card for Pcie 1x slot? My 16x slot is being used by my 8x NIC and my motherboard does not support difurcation. I planned to have two LSI HBA card on my two 1x PCIE slot, is it safe to have drives running on two LSI HBA card?
as long as it fits, it’ll work. but expect reduced speed.
You can indeed open up your PCI 1x slot with a soldering iron. or maybe via a cryptominer riser extension thing. 1x to 16x
I mean… As long as you can get it in there it’ll run. Just not at full bandwidth ¯\_(ツ)_/¯
There will be bottlenecks? I have 7200 rpm drives, can I clarify, if each drives is 200 mb/s and PCIe 1x use 1gb/s. I will be good? The LSI HBA card is one SAS to 4 Sata, so 4 x 200 mb/s = 800 mb/s. I’m not sure if this is how it works.
There will be bottlenecks?
Probably? Maybe? ¯\_(ツ)_/¯ didn’t give a whole lot of information
PCIe 1x use 1gb/s
Pcie gen 3.0 x1 is 1GBps. Is both your slot AND your card gen 3 or higher? Older cards are usually gen 2
4 x 200 mb/s = 800 mb/s
Yes that is how that would work assuming the card uses gen 3… Although given the fact that you said theres 1 SAS port, I doubt its gen 3. Single port cards were mainly a thing on SAS 1/2 cards, which predominantly used PCIe gen 2.
Could I use a M.2 to PCIe riser 8x? My M.2 is PCIe 4.0
Thanks for the advice! Sorry, forgot to give more information about my server I use a
Prime B550M A (wifi) motherboard - 2x PCIe 3.0 1x slots
Ryzen 5500
16 GB RAM
NIC card = Intel X540 t2 (recently purchased)
LSI HBA card I planned to purchase = LSI 9211-4i - PCI 2.0
