to the host supporting the VSA. VSAs can replace the need for a
traditional shared-storage system, enabling a company to more
fully leverage the benefits of server virtualization.  VSAs
range from solutions that simply provide shared storage and add
basic storage features to those that improve storage performance
or incorporate cloud storage access. This tip will focus on the
basic implementations, providing shared storage as an
alternative to more expensive and complex traditional SAN or NAS
systems.  Why shared storage is so important  Server
virtualization is a technology designed to improve asset
utilization (server hardware) while potentially reducing
management overhead. Virtualizing the compute part of the
equation without including the storage component isn’
