SONAS Best Practices – DDN and DCS3700 Intermix Solution Version 1.4.2.1

blueprint

This paper explains the recommended best practices for mixing SONAS back end storage systems. For the initial intermix release, we support mixing DDN and DCS3700 back end storage of the same drive type in the same GPFS storage pool and file system, a specific use case of SSDs for metadata in the system pool, and mixing DDN and DCS3700 back end storage of the same or different drive type in different GPFS storage pools within the same file system. No other intermix configurations are supported at this time. Migration from and removal of DDN storage is also not supported at this time.
