Hello everyone, new to the forum a bit, was hoping to see if I could an answer to my questions here. I work in a DC, just the hardware guy, replacing stuff and installing new hardware/cables no software or expansion on existing servers though. I was fortunate enough to take home an HP DL380p Gen 8 server recently and set up with FreeNAS since that's the only thing I really know was easy. I have 8x 300GB SAS drives installed in FreeNAS raids but was hoping to add some more but unfortunately, I only have one drive cage and they're filled, and the other drive cage has the optical drive cage. I am completely ok with a full 3TB of storage with this server that I have now through the zfs raid. But today I am taking home some more hard drives. 2x 200GB SSD SATA, 1x 400GB SSD SATA, 2x 900GB SAS drives and 2x 300GB drives which I don't have any drive cages for, so they're backups (Ill make sure on the drives SAS/SATA interface but I think I am correct on those). I have 2 more open SAS ports on the motherboard open, the current drives are connected to the RAID controller SAS ports which I don't even use. I also have a 140GB SSD I bought on my own to try to use for the cache but I got stuck on this issue.
I was hoping to see if anyone knew how to add these drives to this server, I know I can buy another backplane (and wires, but I can't find those) but the ones I found were really expensive. I found a cheap way to do it but then my issue is power, getting something like StarTech Model SAS8087S450 which has 4 SATA connectors to a SAS port but like I said power is then the issue. Are there any other suggestions or ideas to make this happen?
Currently, I only set it up as my plex media server, since my current one can't stream 4K movies and this can with the overkill 2x 6 core CPU's and 64GB of RAM. But I will be adding at least one windows VM for some proof of stake mining and I plan on using this as a file server too for my college work and personal stuff, as well as family members, work files back up so more storage the better.
Thanks in advance to anyone can help.
