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."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."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The flexibility and the user-friendly interface are the most valuable features."
"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 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."
"IBM FlashSystem has been stable in our operations."
"This solution is very stable."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The performance is very good and we use this product to enhance our core system."
"IBM FlashSystem is a flexible solution with plenty of features."
"The speed and the ease of installation are the most valuable features."
"It is a bit higher priced than some of the other systems."
"Data storage performance needs to be improved."
"Some improvements to the NFS support would be of interest to us."
"The solution can be a bit complex for those not well versed in the technology."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"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 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'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 should improve its pricing and the mechanism in the reduction pool."
"The ease of installation should be improved. We had issues with the configuration model."
"It could be easier to implement."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."
"The installation is not easy. You need to have extensive knowledge to handle it."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"GUI interface should be enhanced more as there is some issues in copy services."
