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."Ability to scale the number of nodes without having to build additional clusters."
"The solution is extremely easy to manage. This is its most valuable feature."
"The solution is stable."
"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 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 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."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"The maintenance service and support from IBM is very good."
"IBM FlashSystem is flexible, quick, and has a solid design."
"The all-flash storage has tier replication capabilities."
"The speed of the unit is its best feature. It performs very well."
"This solution is very stable."
"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"Data storage performance needs to be improved."
"Isilon has limitations on the number of files that can be generated."
"Its configuration needs to be more straightforward."
"The UID mapping and how to configure mapping-related things is a struggle."
"I would like to see increased reporting and statistics functionalities."
"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."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"It is slightly more expensive, however, it all depends on your supplier."
"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."
"The solution is not able to replicate data in one-to-many scenario."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"The pricing needs to be more competitive."
"The security features can be improved such that the encryption does not affect performance in any way."
