Explanation
One of the Space Efficiency features of Virtual SAN 6.2 that is available for both All-Flash and Hybrid configurations, is the introduction of Sparse Virtual Swap files. Swap files on Virtual SAN by default, are created with the .vswp 100% reserved. In a thin provisioned/guaranteed capacity perspective, it could be said that they are effectively Lazy Zeroed Thick (LZT). RAID-5/6 erasure coding is a space efficiency feature optimized for all-flash configurations of Virtual SAN 6.2. Virtual SAN 6.2 introduces space efficiency features optimized for modern all-flash storage, designed to minimize storage capacity consumption while ensuring availability. One of these features is near-line deduplication and compression. https://blogs.vmware.com/virtualblocks/2016/02/24/vsan62-powercli-sparse-vswp/ technologies.pdf
