Summary
Yes (VMFS v5)
Details
VMwares clustered file system, allowing for concurrent access of multiple hosts for live migration, file based locking (to ensure data consistency), dynamic volume resizing etc.
- vSphere 5.5 increases the maximum size of a VMDK from 2TB-512 bytes to the new limit of 62TB. The maximum size of a virtual Raw Device Mapping (RDM) is also increasing, from 2TB-512 bytes to 62TB (including virtual machine snapshots)
- VMFS Heap Improvements - maximum of 256MB of heap, enables vSphere hosts to access all address space of a 64TB VMFS (addressing concerns when accessing open files of more than 30TB from a single vSphere host)
VMFS5 introduced the following enhancements: Unified Block size of 1MB, smaller Sub-Blocks (8k) and support for small files - all improving disk usage efficiency. Also the file locking performance has been improved.
