I've done quite a bit of research and haven't been able to find a good reason NOT to install ESXi 4.1 on a usb stick. I'm doing some consulting at a company with a Dell r710 which has a internal USB slot. For some reason the guy that was here before decided they needed a $8000 dual quad core, 12GB ram server to share some files. Anyway, back to the topic at hand. The only major issue I found is that you have no redundancy. Although, USB Stick failures are fairly rare what would actually happen if it did fail?
My questions are:
1. Obviously it shouldn't affect any of the VM's data but is it as easy as just reinstalling ESXi over top of the existing or new stick, reconfigure all settings, and then reimporting all of the vm's?
2. Is there an easy way to backup the USB stick/ESXi settings on a regular basis without removing the USB stick?
Note: Guess I could just remove it monthly or quarterly and DD it or make an image of the stick.Once configured the config shouldn't really change much.
3. Has anyone had a USB drive with ESXi on it fail and what did you do to fix it?
4. Any other input for or against installing on a USB stick is welcomed.
Thanks in advance
