Upgrade Dell R720 Backplane
Hi,
I have a Dell R720 server for testing and dev work. (Pls see attached pictures). I have installed all the 16 bays with Enterprise 12Gbs SSDs.
I believe, I have a bad port on the backplane because I replaced 2 SSDs within the same slot 2 days apart and they failed but both work fine if connected to a different slot on the server. Therefore, I was thinking to change the configuration of my server at the same time..
As you can see from the pictures that I have one massive backplane that is connected to all of my 16 x enterprise SSDs via H310 mini monolithic controller (Flashed in IT mode).
I want to split the backplane in this way (or better):
I wish to pass 12 x SSDs to TrueNAS VM running on proxmox and the remaining 4 SSDs to run ZFS pool within proxmox for VM and containers.
As, I already have one H310 mini in IT mode so I think I would need another controller perhaps H710?
I'll need to replace my massive 16 bays backplane with 2 backplanes, add the cables for power and signal and SAS connection?
Could someone from Dell or experienced user advice what parts do I need pls?
Cheers,
Shery

Hi @fahadshery,
First of all, I can't see any pictures loaded. Unsure if they are appearing on your screen. I'll be replying to you by reading your comments.
Secondly, for RAID controllers flashed to IT mode, I'm unable to provide proper information of the configuration that you are planning to have would work, as there is no documentation for me to refer to.
With referring to the user guide of backplane configuration, https://dell.to/3Inom17 , you might be referring to Figure 7. Cabling Diagram—Dual 2.5 Inch (x8) SAS/SATA Backplane—PowerEdge R720 as your plan of changes. Based on my understanding, the servers are cannot be converted after factory build. There are users in this community tried and there is too much hardware changes, inclusive of chassis build, many has given up due to cost constraint which involve whole chassis change.
My suggestion is to just replace the backplane with the same PN# with the current one.
