We performed a comparison between Dell PowerScale (Isilon) and IBM FlashSystem based on real PeerSpot user reviews.
Find out in this report how the two NAS solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."
"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."
"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."
"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."
"The solution's scalability is very good."
"Its most valuable feature is the DR capabilities replication."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The tool comes with cheap disks and works fast for video content."
"This solution is very stable."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."
"The pricing is reasonable."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"The solution can be a bit complex for those not well versed in the technology."
"Some improvements to the NFS support would be of interest to us."
"The solution's rate structure or rate redundancy needs to be improved."
"Dell PowerScale needs to reduce its price."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"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."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"The solution's pricing is a bit high so there is room for improvement."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"The solution is quite expensive. That's one of the downsides to using it."
"The security features can be improved such that the encryption does not affect performance in any way."
"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."
"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
"I would like to see bigger modules."
"The product needs to improve their scalability."
