IBM Spectrum Virtualize: Hot-Spare Node and NPIV Target Ports
IBM Redbooks, Jul 18, 2019 - Computers - 36 pages
The use of N_Port ID Virtualization (NPIV) to provide host-only ports (NPIV target ports) and spare nodes improves the host failover characteristics by separating out host communications from communication tasks on the same port and providing standby hardware, which can be automatically introduced into the cluster to reintroduce redundancy.
This IBM® RedpaperTM publication describes the use of the IBM SpectrumTM Virtualize Hot-Spare Node function to provide a high availability storage infrastructure. This paper focuses on the functional behavior of hot-spare node when subjected to various failure conditions.
This paper does not provide the details necessary to implement the reference architectures (although some implementation detail is provided).
