I would like to add some local attached storage to my ESXi 5 host, which is a dell R510. I am looking to add storage to run backups onto, so it doesn't need to have high IO, but rather capacity. Can I add 2 2TB 7200rpm sata drives in raid1 and not have any problems with ESXi recognizing the storage? I know that there is a 2TB-512 lun limit, but didn't know if 2 2TB drives in a raid 1 would go over the limit. I know that the raid size will still be 2TB, but since that's advertised spaced, the real space should be closer to 1.8TB, but didn't know if the 2TB-512 is advertised space or actual? I hope I'm making sense...Thank you.
