StarWind Virtual SAN Appliance (VSA) has been announced by Starwind Software.
New product announcement from Starwind software. Starwind SAN is known to be usually installed on Windows systems. I covered several times on my website the configuration steps and different possibilities. Recently Starwind announced Free version of Starwind SAN too.
So how about a Virtual SAN Appliance? With VSA you don't need a physical server to run Starwind SAN in your environment. A virtual storage appliance is a VM which runs in a virtual environment and provides you with iSCSI connectivity to an shared storage. Pleas note that i'ts a Preview Edition only, as for now.
Note that Starwind has got a Free version of Starwind SAN with Unlimited Storage. See my article on that here.
A quick quote from the announce.
StarWind Virtual SAN Appliance (VSA), which provides a full blown iSCSI SAN running as a virtual machine. A virtual SAN appliance is the ideal solution for remote offices, virtualized desktops, offsite data replication, testing and development environments or any storage project where a dedicated SAN is overkill.
StarWind VSA provides a highly available storage for VMware vSphere, Microsoft Hyper-V (and Citrix XenServer in future releases). StarWind VSA fully supports the iSCSI storage protocol so your centralized, networked 
storage can be configured on an existing IP network without any complexities. StarWind VSA works with any hard drive type supported by your hypervisor: SAS, SATA, SCSI.
Increase availability of physical and virtual servers by pooling storage resources and streamlining backups, all without purchasing additional SAN hardware.
