December 16, 2025Dec 16 I have 2 unraid servers each with a sas das.I plan to add a 3rd server but as energy consumption and space matter ( i only have a small space in my basement to put my gear) i ordered a mini workstation. It will be well equipped with ssd and ram but lack of hdd. So i plan to add a sas das.It came to my attention that i could use an external thunderbolt to pcie chassis (like the sonnet echo express III, 3x pcie3.0 x8 slots) and throw in a lsi hba. The workstation will have 2 usb4 port (afaik usb4 is compatible with thunderbolt 3). When i look at sonnet compatibility list only arecca and sonnet adapters are listed. Are lsi hba in it mode compatible with this?On sonnet site they claim drivers are available on linux since kernel 5.0.edit : if such a config is working would it be possible to passthrough a vm individual disks or you have to pas the whole controller?
