Santosh Bharadwaj Rangavajjula - PeerSpot reviewer
Product Manager at a manufacturing company with 10,001+ employees
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.
Muhammad Saqib - PeerSpot reviewer
System Engineer at Hybrid Tech
Uninterrupted upgrades accelerate performance with good support
I would rate the solution eight out of ten. It should be noted that in Pakistan, some parts are not readily available, and we need to import them from Singapore or other countries. We encountered an issue with a customer where the midplane failed and was not available. We had to wait for several days for a replacement, even in a 24/7 support case. Additionally, we faced motherboard failures in the customer's environment, encountering two motherboard failures simultaneously. We obtained one motherboard immediately, yet had to wait ten days for another. These issues should have been resolved promptly given the 24/7 support level.

Measuring Up: EMC XtremIO and HP 3PAR
Leading up to EMC World 2015, IT Central Station asked how I would compare EMC XtremIO and HP 3PAR. Until recently, the flash storage conversation in my organization and many others has centered on XtremIO and Pure Storage, the leaders of the all-flash array (AFA) space. To that end, I've written a…
