I recently attempted to setup a virtual machine inside ESXi and I'm trying to get it to have access to an entire secondary drive in the server for data storage and whatnot.
When I go into 'Add Hardware' and select hard disk, I'm presented with three options:
- Create a new virtual disk
- Use and existing virtual disk
- Raw Device Mappings
By obvious choice I'd want to use raw device mappings, but it is greyed out. I've tried this guide to create a fake virtual disk that points to a raw drive uuid but this yielded no working results.
I would much rather not create a virtual disk the entire size of the drive as a) I can't truly acheive a virtual disk the full size of the drive and b) there is increased overhead using a virtual disk instead of a raw device mapping (so I'm lead to believe at least).
While it is a single un-raided mechanical drive, it offers just the amount of performance I require from it on it's own. I feel that by using a raw device mapping would yield the best read/write speeds of the drive and also would be convenient to be able to remove the drive for use in another computer to read the data thats on it - rather than having to go through a .vmdk file to access stuff should this be required for any reason.
