File sharing has supported collaboration and disaster recovery but security support still needs work
Dell PowerScale can improve specifically for AI workloads, particularly on the MCPs. I would add that we have not seen an official MCP from Dell PowerScale and are relying on open source. It would be valuable to have an MCP server that we can set up directly with them. Regarding Dell PowerScale's AI capabilities, I think its governance and security could be better. We have Superna that we buy along with Dell PowerScale, but we are seeing very big problems with integrating it. Superna is primarily for the security use case, as we want to prevent cybersecurity attacks and ransomware attacks. If Dell is providing this as a supplementary feature, it should provide better support. Regarding Dell PowerScale's AI capabilities, I do not see much accuracy and reliability of output. This is actually a security problem because Dell does not provide official MCP servers while most other vendors are providing it. This forces us to rely on open source, which is not secure. Dell PowerScale plays a role in my organization's AI initiatives as we want to use the Metadata IQ functionality from Dell PowerScale; however, there is not enough support and extensive documentation for us to be able to do this.

As you can see at https://www.nersc.gov/assets/Uploads/W01-ZFS-and-Lustre-June-1024.pdf, the Lustre performance can be scale up to 1.5 TB/sec in the real world. The EMC Isilon performance record is much lesser because it limited by the m...
