VMware vSphere 5.5 Update 1 – VMware 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
