    I have been told I can run a case of harddrives for storage, without actually building a whole server.

    I already have one to connect the drives to somehow.

    Now if someone will educate me on how this all works that would be great

    A little more information would be useful. What is your host operating system? How much storage do you currently have and how fast has it been/do you foresee it growing yearly? What is your use case for the storage (VM, mail, basic file serving etc?) What is your budget for this project?

    ESXi 6.5.0/ idk its like 1.2tb across the 3 data stores. not nearly enough. Growing yearly? no, probably every few years. mostly VM/ basic file sharing and idk on budget, not concerned the price of drives atm- looking for help figuring out how this idea will work as far as connections and go from there

    you'll need an hba with external port or ports. i guess you'll have to first decide if you want 6g or 12g.

    also, how many drives do you want to use?

    I believe 6g is fine, the current drives in the hp are all 6gb sas, and I have no issues with sluggish system performance at all.

    at least 4+ drives- I am thinking of slapping like 1tb drives together, maybe 2tb if I can find a good deal


    Also for some reason that page fails to load for me

    for that many drives, you don't really need an expander. raid or hba card with 2 external sff-8088 ports, run 2 sff-8088 mini sas cables to your external enclosure into a sff-8088 to sff-8087 adapter with sata/sas breakout cables at the end. that will run 8 drives.
