Hi,.. i'm getting to my last research for the whole server and vm thing.
This issue is not specific for virtualized computing, but i see best fit in this part of the forum.

I've been researching for half a year and i guess i nearly got it all figured out.
There's only one thing that's left.


In my system, i've got/want
- 2 SSDs (intel 330, mlc) for VM's, L2ARC and ZIL
- 1 USB stick with esxi
- 4 WE Red drives in ZFS RAIDZ2

In one VM, I want to have a guest OS with debian as a webserver. To have a good redundant system and easy backups, I want to use /var/www/ and mysql running on the ZFS file system. I got a few ideas how to do it. Which one is best? or do you got a better suggestion?

My ideas:
1. Thinking of mounting a directory of the NAS into debian for the websites, and another one for the database. (im just a bit unsure about the vunerability of a NAS, since the webserver will nmainly function as development environment)
2. Running the full webserver VM on the SSD and back it up with snapshots, storing them on the ZFS raid for rollback.
3. Run a specific VM for automated backups of files and mysql using login via (S)FTP and some other tool for the DB.

ZFS is nice, but it holds back on making the bare metal server universal.
 
You don't have to run your servers on Debian. Run them on OI/Solaris in Solaris Zones.

OI and Solaris 11 both have a 1-click Apache/MySQL/PHP (SAMP) stack. OI also has good Postgres support. There's also Xampp for Solaris/OI.

Solaris 11 on bare metal also runs VBox very well, especially headless servers from zones. Then everything's on ZFS regardless. ;)
