We performed a comparison between Dell PowerScale (Isilon) and VAST Data based on real PeerSpot user reviews.
Find out what your peers are saying about MinIO, Dell Technologies, Red Hat and others in File and Object Storage."The stability of the solution is good."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The solution is stable."
"The tool's most valuable features are scalability and stability."
"The solution's scalability is very good."
"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."
"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."
"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"Its configuration needs to be more straightforward."
"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."
"Isilon has limitations on the number of files that can be generated."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"I would like to see increased reporting and statistics functionalities."
"Data storage performance needs to be improved."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
