IBM Spectrum Scale for high availability

Set up IBM Spectrum Scale as the high availability (HA) solution for IBM® Spectrum Symphony, removing NFS as the only supported shared file system restriction.

With this setup, you create and configure an IBM Spectrum Scale HA pool for IBM Spectrum Symphony to use as a shared configuration and work storage system.

Before creating and configuring an IBM Spectrum Scale HA pool, make sure of the following:
  • The IBM Spectrum Scale binary is installed on all IBM Spectrum Symphony management hosts and creates an IBM Spectrum Scale file system.
  • If IBM Spectrum Scale is only configured to support IBM Spectrum Symphony HA, you create one HA pool; if IBM Spectrum Scale is also used for the MapReduce workload, you create three pools (system, data, HA) separately for better performance.
