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?
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.
Probably? Maybe? ¯\_(ツ)_/¯ didn’t give a whole lot of information
Pcie gen 3.0 x1 is 1GBps. Is both your slot AND your card gen 3 or higher? Older cards are usually gen 2
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.
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
Could I use a M.2 to PCIe riser 8x? My M.2 is PCIe 4.0
