What's new in Virtual SAN 6.2

The Update 2 includes the new VSAN 6.2 which brings some new features.


- Deduplication and Compression: reduce the storage consumed up to 7x with a minimal impact on CPU and memory overhead. To activate this feature, navigate to the VSAN management view and select the Enable option in the drop down menu of the Deduplication and compression field.


- RAID-5/6 (Erasure Coding):  the new fault tolerance method ensure the same levels of availability saving up to 50% of capacity consumption versus RAID-1. Configurable through the VM Storage Policies, this functionality is enabled in the Failure tolerance method field.


- Sparse Swap Files: virtual swap files are created when VMs are powered on and used when the physical host memory is exhausted. This setting creates virtual swap files as a sparse object on the Virtual SAN datastore consuming capacity on Virtual SAN only when they are accessed. As result, less space is consumed on the Virtual SAN datastore.

- Quality of Service / Limits: this feature that limits the number IOPS an object may consume. Applied to Virtual SAN objects through a Storage Policy, quality of service can be applied to
individual components or the entire VM without interrupting the operation of the virtual machine.


- Integrated Performance Metrics: new release includes a number of new graphs and data points that provide performance information at the cluster, host, virtual machine, and virtual disk levels. These metrics provide quick visibility to the entire Virtual SAN cluster, showing how Virtual SAN and the objects that reside on it are performing.


- Enhanced Health Service: the health service actively tests and monitors a number of items such as hardware compatibility, network connectivity, cluster health, and capacity consumption.
