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."For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"Its most valuable feature is the DR capabilities replication."
"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."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"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."
"Ability to scale the number of nodes without having to build additional clusters."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"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."
"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"The solution isn't suitable for small environments or small customers."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"I would like to see increased reporting and statistics functionalities."
"The solution can be a bit complex for those not well versed in the technology."
"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."
"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
