Prerequisites for automated scanning

You can use IBM Storage Scale automated scanning features.

IBM Spectrum® Discover supports two levels of automated scanning of IBM Spectrum Scale systems. Both levels require that IBM Spectrum Discover must establish a password-less Secure Shell (SSH) connection to the IBM Storage Scale clustered system that is being scanned.

The difference between the two levels lies in the manner in which the output is handled. The factors that are considered inspects whether:
  • The output of the IBM Storage Scale policy that is run to do the scan is stored in a file (which then must be automatically copied back to IBM Spectrum Discover and ingested locally); Or
  • If the output is, instead, pushed to the ingest Kafka queue of IBM Spectrum Discover system directly from the IBM Storage Scale policy output.

The Kafka queue of IBM Spectrum Discover system is more space-efficient and time-efficient but has certain dependencies on the IBM Storage Scale clustered system that must be met so that it can function. The IBM Spectrum Discover automated scan code determines whether the dependencies are met on the IBM Storage Scale clustered system.

If the dependencies are met on the IBM Storage Scale clustered system, it attempts to scan the system by using the optimized path. If the dependencies are not met on the IBM Storage Scale clustered system, it defaults to the file copy path.

The following sections list the prerequisites for creating a connection and performing automated scanning. These prerequisites consider security and performance factors. For more information, see IBM Storage Scale scanning considerations .
