HPE DL380 Gen10 Server Hard Disks Upgrade to 20TB

[Rodex112]

I looking at upgrading HPE DL380 GEN 10 Server ,Product ID 826564-B21. The server has 3 x Seagate Enterprise Capacity 2.5 2TB 7200RPM SATA 6Gb/s 2.5-Inch Hard Drives,Model (ST2000NX0253) in raid 5 configuration on HPE Smart Array S100i SR Gen10 onboard controller. I need to upgrade the server with additional 20TB DISK space, therefore would like to know the type and number of drives required to achieve the 20TB disk space with Raid.Also need to know if the HPE Smart Array S100i SR Gen10 Controller support dual raid configuration.

As per the quickspecs you can connect 14 drives as it has 14 SATA Lanes:-
https://www.hpe.com/psnow/doc/a00019427enw?jumpid=in_lit-psnow-red
Storage interface (SATA)  o Up to 14 SATA lanes  o 6Gb/s SATA technology  
Up to 14 physical drives 

Since you are already using 2 TB drives for Raid 5 meaning 2TB x 3
So remaining we have 11 physical lanes. 

If you want to create additional 20TB space then you have to add 11 x 2TB SATA drives with Raid 5 and you will get 20TB.
If you use these 11 drives with other Raid then you will be getting less space depending on parity. You can check in google searching for Raid calculator.
