What is a VMFS-6 file system?

The VMFS-6 file system is indeed the latest version of VMware's Virtual Machine File System, which has been designed to offer enhanced performance and improved management capabilities compared to its predecessors. One of the key improvements in VMFS-6 is its increased scalability, which allows it to support larger virtual machines and greater storage capacity. It also introduces features such as automatic space reclamation, which enhances storage efficiency by automatically returning unused space to the storage pool, and support for larger block sizes, facilitating better handling of larger files.

In addition, VMFS-6 supports long file names and improves snapshot performance, which is critical for maintaining the integrity and responsiveness of virtual machines. By integrating these features, VMFS-6 is optimized for modern enterprise environments, making it a robust choice for hosting virtual machines that require high availability and performance.

The other options mischaracterize VMFS-6; it is not optimized specifically for cloud storage, nor is it a previous version since VMFS-5 was the last iteration before VMFS-6. Also, it is not a temporary file storage solution; it serves as a permanent and essential file system for managing virtual machine files and their respective resources.
