Adding an additional SATA Hard Drive to R720 Server
I am adding a 640GB Hard Drive to a Dell R720. It already has 2 300GB SAS drives on RAID 0. I'm going to use this larger drive for storage. I also plan on adding a 3TB SATA HD as well and using it as added storage.
In the PERC H710P Mini BIOS Configuration Utility, I'm under the VD Mgmt tab and I have the Unconfigured Physical Disk highlighted. F2 does nothing. If I go over to the PD Mgmt tab and highlight the drive, I can hit F2 and a minimal box comes up hat only lets me turn on or off the blinking LED or Make Global HS.
Can I add just the one drive? Do I have to use RAID if I only want one drive?
Thanks!

Non-RAID is not supported, you will need to configure your standalone disks as 1-disk RAID 0's.
A better use of your drives would be to convert it to ANYTHING besides a RAID 0. You should not be using RAID 0 without a very good reason (and there are very few 'good' reasons).

Well, here's my second solution.
I have 2 640GB WD Drives (Identical models). I could use those in a RAID 1.
Then I have 2 4TB SAS drives in my computer now. I can put them in this server and use a 6GB external drive to store the stuff that's on that. Mostly it's my VirtualBox VMs but there's other stuff on them as well. I can use those in a RAID 1
My next question revolves around your issues with RAID 0. The drives I currently have formatted and running as RAID 0... Is there an easy way to convert those to RAID 1 or do I need to just re-initialize them and reinstall everything? All I've done is installed Debian Server and Proxmox on it. I'm thinking I should just redo everything in RAID 1.

You can convert the 2-disk RAID 0 to a 3 (or more) disk RAID 5 (or RAID 6), but going to a RAID 1 would require a wipe/reload or backup/restore.

Hi, Phydoux2112, that's right, even with just one disk, you need to RAID and yes, you can use the 3TB.
