November 2, 20205 yr My server as it stands today is a culmination of 20 years of trying, rebuilding, failing, reading forums and searching the web for solutions. MB: ASUS A88X-PLUS CPU: AMD A10-7850K Black Edition RAM: 2x4GB 1600MHz (PC3-12800) DDR3 CL10 PSU: Corsair 1000W modular Controller: Highpoint RocketRaid 2340 Case: Lian-Li cube case With theese HDD trays: Chieftec The drives as of now consist of: 4x 2Tb drives of various make and model. 5x 3Tb drives of various make and model. They are set up in RAID 5 in the Rocketraid controller. My plan is to get a new controller and 3-4 new drives of at least 4 Tb, probably 8Tb. and ditch the 2Tb drives. I also need a way to transfer what is on there to the new unraid system. The RR2340 has worked flawlessly and i love it, but... it's getting old and highpoint has long since forgotten about it, the "open source" drivers were a pain to get working on ubuntu 18.04 LTS which i run now. At the most i had 20 drives in this rig, then mated with the RR2320 which i still have stored away. I want to try unraid and so need some suggestions, cost is a big issue and just how i am going to move all the data is also an issue, haven't figured that one out yet. I am looking at the LSI SAS 9300-4i and it says it supports 1024 storage devices? But just 4 without any expanders, right? Otherwise it has to be this LSI SAS 9305-16i. What are your thoughts?
November 2, 20205 yr LSI is a good option, number of devices it supports without an expander is in the model, e.g., 4i=4 internal devices.
November 3, 20205 yr Author Do they work with all expanders as long as they are the same SAS standard or are there proprietary limitations? If i use an expander will i see the drives behind it as individual drives or as an array of disks?

November 4, 20205 yr Author Ok, next question, transferring files from the existing raid arrays to new drives. I am thinking of buying 3 8tb drives and copying the contents over to two of them, and use the last for parity. Can i just build the server with the two data drives and have the data show up directly or do i have to copy again? If so what filsystem should i use? Edited November 4, 20205 yr by randknu

November 4, 20205 yr Author Thanks a lot, i can use the onboard SATA connectors together with the HBA too so i should have plenty of space available.
