I have a Dell PowerEdge 1900 that I want to put to use. It's got the following specs:
Processor: 2 Intel Xeon Dual Core
Memory: 4 GB RAM
Hard Drive Configuration: 2 - 80GB, SATA, Hard Drives (RAID 1 Config)
Hard Drive Controller: PERC 5/i, Integrated Controller Card
I would like to install XenServer on it. Then, I'd like to setup a Samba Server using Ubuntu 14.04 using encryption. I'm not 100% sure what is the best course of action. I thought encrypting a partition or one of the hard drives using LUKS may be possible before installing Ubuntu? I know you can encrypt your home directory during Ubuntu setup, but is that sufficient? Any direction would be greatly appreciated. As much detail in your suggestions as possible, please!
