Raid 1 Questions

Recommended Posts

Posted · Original PosterOP

I have a Dell PowerEdge T320 running Windows Server 2012 R2 Standard with 3x 3TB hard drives on Raid 1.

 

1. How do I know if hot swapping without powering off the server is supported?

 

2. If I'd like an off-site HDD copy, could I just remove a drive and place an empty one in, will it sync automatically?
 

3.If I want to update the off-site HDD copy, can I just put it in and it will sync with the hard drives already in it?
I don't want files that have been previously removed on the server but are still on the off-site HDD to copy back onto the server when I put it in to update it.

No, as far as I know. The RAID controller will treat it as a new disk because it went out of sync.

 

Overall, you've better off using a separate drive and making a copy of the array onto it.

As far as I can tell, Dell PowerEdge T320 supports hot-swappable drives. Also, all SATA and SAS drives are hot-swappable. However, not sure if you can check this somewhere. in Dell management software. As already mentioned, you can test this. For backups, better use a dedicated external HDD with smth like Rclone or Duplicati to perform a backup.
