VMware vSAN? delivers a new HCI experience architected for the hybrid cloud with operational efficiencies hat reduce time to value through a new,intuitive user interface, and provides consistent application performance and availability through advanced selfhealing and proactive support insights.
Seamless integration with VMware’s complete software-defined data center (SDDC) stack and leading hybrid cloud offerings makes it the most complete platform for platform for virtual machines—whether running businesscritical databases, virtual desktops or next-generation applications.
As a component of vSphere, VSAN extends the hypervisor to pool and abstract serverbased
storage resources, much the way vSphere pools and abstracts compute
resources. It is designed to be much simpler and more cost-effective than traditional
external storage arrays. Users of vSphere should be able to learn VSAN and become
productive quickly.
VMware vSAN uses a software-defined approach that creates shared storage for virtual machines. It virtualizes the local physical storage resources of ESXi hosts and turns them into pools of storage that can be divided and assigned to virtual machines and applications according to their quality-of-service requirements. vSAN is implemented directly in the ESXi hypervisor.
You can configure vSAN to work as either a hybrid or all-flash cluster. In hybrid clusters, flash devices are used for the cache layer and magnetic disks are used for the storage capacity layer. In all-flash clusters, flash devices are used for both cache and capacity.
