Coinciding with the announcement and launch of VMware vSAN 6.2, VMware has released a new technical white paper titled "What's New with VMware Virtual SAN 6.2" providing additional details on architectural overviews and new features such as de-duplication, compression, erasure coding, Quality of Service (QoS) using IOPS limits, and new performance service and improved health service.

Virtual SAN is natively integrated with vSphere and it can be configured with just a few mouse clicks.  Since disks internal to the vSphere hosts are used to create a Virtual SAN datastore, there is no dependency on external shared storage. Virtual machines can be assigned specific storage policies based on the needs of the applications. These workloads benefit from dependable shared storage with predictable performance and availability characteristics.

The 17 page white paper is written by Jase McCarty, a Senior Technical Marketing Architect at VMware, a friend of mine and a co-author of one of my server virtualization books; and by Jeff Hunter, also a Senior Technical Marketing Architect at VMware.  They write:

The new release of Virtual SAN, version 6.2, further reduces TCO by delivering up to 10x greater storage efficiency.  Virtual SAN 6.2 is also optimized for modern all-flash storage, delivering efficient near-line de-duplication, compression, and erasure coding capabilities that enable high performance all-flash systems for as low as $1 per GB of usable capacity-up to 50% less than the cost of lower-performing hybrid solutions from the leading competition.
