You are a VMware consultant for a large enterprise running VMware vSphere 4.1. You are
reviewing the upgrade documentation created to take the company to version 5.X of the software.
The upgrade has several requirements, including the following:
Minimize the impact to the business applications
Do a full rollback, if required, for any issues not foreseen by the project team
You notice in the documentation that the upgrade to VMFS 5 is mentioned as being nondisruptive
and having zero impact on the technical solution. Is this technically correct?
A.
Yes
B.
No
Explanation:
In this example, a VMFS 5 upgrade cannot be rolled back without extra scratch space and
withoutusing storage vMotion. These things could add extra I/O load on the systems and affect the
first requirement.
