Smaller businesses are no different from larger organisations when it comes to a desire for business continuity and high levels of system availability. VMware can provide these benefits but has, until now, required physically shared storage to do so…which is a level of cost and complexity that many smaller organisations do not want; VMware’s vSphere Storage Appliance (VSA) gives such users an alternative software-based approach that provides the necessary capabilities of shared storage without physical hardware, and the associated costs and complexity.
