IBM® Spectrum® Virtualize software running on IBM Storage products provides clients an opportunity to maintain two independent copies of a single data volume across two sites by using the IBM Spectrum Virtualize Metro Mirror feature.
Starting with Spectrum Virtualize V126.96.36.199, two site replication can be extended to a third site. The use of a three-site setup means data can be replicated asynchronously to an independent system in a third site. This three-site setup is called IBM Spectrum Virtualize 3-Site Replication. In this IBM Redbooks® publication, we describe IBM Spectrum Virtualize 3-Site Replication and its implementation, and highlight configuration guidelines, preferred practices, and troubleshooting procedures.
This IBM Redbooks® publication is intended for experienced storage, SAN, and IBM FlashSystem® administrators and technicians. Understanding this book requires advanced knowledge of these environments.
