BeardElk Posted March 11, 2022 Share Posted March 11, 2022 I´m planning to expand my Unraid server beyond the capability of the number of mb sata, so I know I need an HBA. And since I´m planning for the future, I'm looking beyond the normal capability of an 8T HBA, but I´m a newbie rookie at this, so I need some input from someone who knows these things. The HBA I´m planning on buying is an LSI 9211-8I, with a Lenovo 03X3834 expander card. I´ve read that this combo (with the hba flashed to IT) should work flawlessly with unraid, however, I cannot find what cables to buy between the hba and expander card/expander card to my drives. The hba has SFF-8087 connectors, but I cannot find what the expander card has. It looks the same, but if someone could help me I would appreciate it! (again, this is all new to me, didn´t know about hba´s until a couple of days ago) Is it as simple as SFF-8087 to SFF8087 between the HBA and expander card, then SFF-8087 to sata from the expander to my drives? I´m running sata drives, and trying to do this as "cheaply" as possible. Quote Link to comment

BeardElk Posted March 11, 2022 Author Share Posted March 11, 2022 (edited) A new question about HBA and expander cards, does the expander card use any pci-e bandwidth? The card I mentioned in the og post requires a 4x slot, but say I just got a 1x available, would I lose performance? I´m planning a mobo upgrade as well, but the one I´m looking at got 3 x16 (1x16 1x8 1x4) and 2 x1, I then got 2 GPUs as well, 1 for a VM and 1 for transcoding. Is it better to put the transcode GPU in a 1x slot or the SAS expander? What config is optimal with the above-mentioned parts? Edited March 11, 2022 by BeardElk Quote Link to comment
