Storage virtualization brought many advanced features to SAN/NAS world.SAN/NAS appliance moved one step forward and made any system can be act as virtual SAN/NAS box.For an example using openfiler, you can provision LUNS and assign to any server using ISCIS protocol.The same way it can act like NAS filer as well.Here I have list down the SAN/NAS appliance which are industry leading products.You can download it freely  and install it.

These products are being used in many organization and very reliable products in data storage. It supports SNMP,SMARTS and syslog for monitoring.So failure can easily detected and notified to administrators.In UnixArena,I have used openfiler to setup VCS cluster between two Solaris nodes.
