What is the maximum number of VMFS versions supported in ESXi 7.0?

In ESXi 7.0, the maximum number of VMFS versions that are supported is two. Specifically, this includes VMFS-5 and VMFS-6. This dual support allows for the use of different VMFS versions within the same environment, making it easier to manage and migrate virtual machines that may have been created on earlier versions.

VMFS-5 was the version introduced with vSphere 5, and it supported features like increased maximum file sizes and larger datastores compared to its predecessors. VMFS-6, introduced in vSphere 6.5, brought further improvements such as support for features like 4K native sector support and enhanced metadata handling.

While earlier versions of VMFS existed, in the context of ESXi 7.0, the support is explicitly for these two versions. As such, this dual support contributes to flexibility in managing storage infrastructure while ensuring compatibility for virtual machines across the two versions.
