I'm looking at getting a Raid Enclosure for running vm's on. I have noticed that the ones that I have found, only have 1 sata port on the back of them. I'm going to be running the hard drives in this enclosure in RAID 0. Would this 1 sata port be a performance bottleneck when running the vm's? I will also be getting 3 - 4 250gb 7200rpm drives, and running 6 - 8 vm's on the machine. I can't have an internal setup because the computer only has 1 hard drive bay.
Basically I'm going to have a test environment. There will be a Domain Controller server running AD, DNS, DHCP, and will have a couple user accounts. Then I will have a Windows Deployment Server, Configuration Manager Server, exchange server, and any other server to test and learn how to use. Those servers will probably not be running at the same time unless there is a good reason to do so. Then the rest will be dummy win7 machines, to verify servers are running and doing what they are suppose to do. I'm trying to prepare for microsoft certifications and implement new solutions into my work environment if they work out.
