DataCore released a version of its Virtual SAN Appliance (VSA) this week for Microsoft Hyper-V environments. The product allows customers to access Hyper-V features such as live migration, dynamic load balancing and high availability without having to purchase an external storage area network (SAN) storage.

Using locally attached internal disk drives, the DataCore VSA creates a virtual iSCSI SAN that can pool up to 1 TB of capacity. VSA includes the ability to "thin provision" VM storage to save capacity, create snapshots for instant volume cloning and speed up application performance by leveraging surplus server memory.

DataCore VSA comes as a virtual appliance in Microsoft-standard Virtual Hard Disk format, and can be downloaded from the DataCore website for a free 30-day trial.
