TR-4551: StorageGRID Webscale NAS Bridge Best Practices


This document discusses best practices and recommendations when deploying and sizing the StorageGRID Webscale (SGWS) NAS Bridge and discusses configuration, use cases, architecture, performance, and maintenance for the NAS Bridge integrated with StorageGRID Webscale.


The NAS Bridge functions as a protocol bridge between NAS and object protocols. The NAS Bridge presents either NFS or CIFS shares to client applications. Files written into the shares are stored persistently in the object store as whole files; the bridge does not modify the source files. Files ingested by the NAS Bridge are stored into StorageGRID Webscale using the S3 protocol.  The NAS Bridge supports file-object duality in which a file stored using a NAS protocol can be retrieved using the S3 protocol as an object. The NAS Bridge currently deploys only as a virtual machine appliance.

What are the limitations when it comes to NFS writes? I don't see that in the TR. 
I saw somewhere that only single NAS Bridge can do writes but not sure it's it's per whole StorageGRID installation, per site or per tenant. 


Each share/export in NAS Bridge point to a bucket in a grid.  This is available throughout whole grid or indepedent of sites.  However, only one NAS Bridge can access that bucket at a time.
