We performed a comparison between Dell PowerScale (Isilon) and VAST Data based on real PeerSpot user reviews.
Find out in this report how the two File and Object Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The flexibility and the user-friendly interface are the most valuable features."
"The solution is extremely easy to manage. This is its most valuable feature."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."
"Dell PowerScale's performance is good."
"The solution's most valuable features are scalability and flexibility."
"The stability of the solution is good."
"Ability to scale the number of nodes without having to build additional clusters."
"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."
"Some improvements to the NFS support would be of interest to us."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"The solution's rate structure or rate redundancy needs to be improved."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"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."
"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS. It would be key if this was made possible."
"There is room for improvement in its handling of object storage."
"The UID mapping and how to configure mapping-related things is a struggle."
"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."
