Architecting VMware vSAN 6.2 : vSAN Technology and Features Overview
   
vSAN Technology and Features Overview
vSAN transforms industry-standard x86 servers and directly attached storage into radically simple Hyper-Converged Infrastructure (HCI) to help eliminate high IT costs, management complexity, and performance limitations. The tightly integrated software stack includes vSphere with vSAN to deliver a radically simple, enterprise-class native storage; and vCenter Server, the unified and extensible management solution.
Being natively integrated with vSphere allows vSAN to be configured with just a few mouse clicks. Because disks internal to the vSphere hosts are used to create a vSAN datastore, there is no dependency on external shared storage. In addition, virtual machines can be assigned specific storage policies based on the needs of the applications. These workloads can then benefit from this dependable shared storage with predictable performance and availability characteristics.
vSAN version 6.2 also further reduces TCO by providing up to 10x greater storage efficiency in an optimized all-flash storage solution, which delivers efficient near-line deduplication, compression, and erasure coding capabilities that enable high performance all-flash systems for as low as one dollar per GB of usable capacity, which might be up to 50 percent less than the cost of lower-performing hybrid solutions or shared storage solutions from the leading industry competitors.
