VMware Virtual SAN : Basics of VSAN
With the release of VSAN, VMware fulfills the true software-defined data center with the combination of virtualized compute, network and storage. After VSAN release, I will definitely say that buying storage for your infrastructure is not only limited to the storage vendors but also VSAN will play a major role because which is part of hypervisor after vSphere 5.5 Update 1 onwards. Virtual SAN 5.5 is a new hypervisor-converged storage tier that extends the vSphere hypervisor to pool server-side magnetic disks (HDDs) and solid-state drives (SSDs). By clustering server-side HDDs and SSDs, Virtual SAN creates a distributed shared datastore designed and optimized for virtual environments.Virtual SAN is a standalone product that is sold separate from vSphere and requires its own license key.
