Hello and welcome to the forums
I do not know the hardware for ESXi host A and B.
But in a scenario that you want iSCSI storage and vMotion,
at least you need 2 extra NICs per ESXi host (VMotion requires Gigabit)
If you want host C for shared data storage,
- you can go for a VM that does the job (worst scenario)
- Make it a dedicated iSCSI box with OpenFiler (http://www.openfiler.com/) or FreeNAS (http://freenas.org/downloads) (better)
And do some additional reading on this forum about using thes products.
- Buy a seperate Storage box (best)
If BOX C has an IDE drive, performance is not that good
I do not know if you are gooing to run a production environment or just a lab.
In case of production, I would recommend to check the Compatibility, in case of support issues
