z⁄VM Education - Unit 14 - Single System Image(SSI) - Part 1

z/VM Single System Image (SSI) is the technology used to cluster up to eight z/VM systems. Member systems can be managed, serviced, and administered as one system. An SSI cluster includes capabilities such as multi-system installation, single point of maintenance, autonomic minidisk cache management, and Live Guest Relocation (LGR). This video discusses the basics of setting up and managing a z/VM SSI cluster.
