HC3x Product Specifications

HC3 is the future of the IT infrastructure: a scalable, highly available platform that runs your applications. As a completely integrated cluster, HC3 brings servers, storage, and virtualization together, creating a turnkey solution that’s as easy to manage as a single server.

Guest OS Support





Windows Server 2012, Windows Server 2008 R2, Windows Server 2003 R2, Windows 8 (64 bit), Windows 7, Windows Vista, Windows XP

RHEL/CentOS 4, 5, 6
