Xan Posted June 13, 2019 Share Posted June 13, 2019 (edited) Hi Everyone, I am new to unraid. Just booted to the OS for the first time tonight. I recently acquired a Dell r520 from a 'friend' and had a few questions running unraid. 1. The perc was removed from the server. I have the bios set to run ahci (not raid mode). Can I just add nas drives to the caddys --> the backplane then configure those in unraid OR do I need to buy myself a raid controller? I am familiar with how unraid works and the fact that you DO NOT need a raid controller. My question is whether I need the perc for this to even work. 2. Cache Drive: My plan is to remove the DVD ROM and add a caddy with an SSD for this. Does this seem like the right plan? 3. Any suggestions for running unraid on this server? Thanks, X Edited July 20, 2019 by Xan Quote Link to comment

Frank1940 Posted June 14, 2019 Share Posted June 14, 2019 Try googling unraid dell r520 as Google does a much, much better job of searching this forum than the forum's search engine. (While I could post up a couple of links, you should more quickly find what you are looking for if you searched the result yourself. ) Quote Link to comment

(While I could post up a couple of links, you should more quickly find what you are looking for if you searched the result yourself. ) Appreciate it. I have googled a bit and the search on the forums is not the greatest. I had some questions because the way the board is configured did not make sense. The backplane plugs straight into what appears to be a sata a-d plug on the motherboard. My assumption is that disk 0,1,2,3 can run without a perc in the sata a-d slot, while 4,5,6,7 will need some sort of controller. There are also 2 SAS plugs for SAS-A and SAS-B on the backplane that go straight to the motherboard. Can I run these as regular sata and bypass the need for a perc? Quote Link to comment

Xan Posted July 14, 2019 Author Share Posted July 14, 2019 (edited) In case someone finds this. 1. You can run 4 drives from the backplane to the SATA/8087 port on the Mobo. Swap the optical for an SSD and run it fine with no additions. 2. Caddy swap works fine. Auto detects in #1 above. 3. After flashing my perc h310 to IT mode. I ran a comparison with the s110 onboard non-raid passthrough then after the flash ran it again on the IT mode h310. For some reason I expected them to differ but in fact they were nearly identical.

mtrepanier Posted June 11, 2020 Share Posted June 11, 2020 Just got a r520 with the h710 mini on it. Yay the h710 mini is flashable to IT mode now. But my question is, do you have an how to, or picture of how it look the optical drive replacement to a SSD drive? Want to add a SSD drive as my cache drive for Unraid Quote Link to comment
