I'm fairly tech savvy, but am very new to the server environment. I have an HP ML110 with WS 2012 R2 installed. I have 3 TB HDDs, with two of them in a RAID 1 (the third is just hooked up but no recognized because it hasn't been added to an array.) I'm not married to this configuration, it's just the way I did it when I started.
My end goal is to have a home server that runs AD DS, DNS and DHCP and also acts as a file server. I don't have any processor-intensive applications (SQL db, etc).
I wanted to know what is best practice regarding:
1. RAID configuration. Is it just best to take all my physical disks and create 1 large array?
2. 1.5TB at RAID 1 or 3TB at RAID 0?
3. Is it ok (for performance purposes) to have AD DS, DNS and DHCP on the same server?
4. Should I use Hyper-V and create multiple virtual servers to run the above services?
If there are any other broad rules of thumb that I should be aware of please let me know.
