I creating a file server for a client, I want to set up RAID 1. However, I'd like HD0 (aprox. 2 40-80 GB drives) for the OS. I'd like to set up another HD, HD1 (2 1TB drives for file storage) seperate of the first RAID 1. The files that need to be stored will be large graphic files. This will be my first SCSI - RAID configuration I have ever done, so please forgive my ignorance.
My question is, do I need 2 SCSI controllers to accomplist this? Or can I set up 2 RAID 1 Mirror arrays on 1 SCSI card.
My plan is to back up the HD0 and HD1 (1 TB drive) to off premise location using the Internet via VPN routers.
Any additional information or advice is welcome. Thank you.
