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."PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"The flexibility and the user-friendly interface are the most valuable features."
"The tool's most valuable features are scalability and stability."
"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."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"The most valuable feature of the solution is its performance."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"Its most valuable feature is the DR capabilities replication."
"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."
"The solution’s interface and pricing could be improved."
"Dell PowerScale's deployment is not easy."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"The solution isn't suitable for small environments or small customers."
"Some improvements to the NFS support would be of interest to us."
"The UID mapping and how to configure mapping-related things is a struggle."
"There is room for improvement in its handling of object storage."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"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."
