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."Its most valuable feature is the DR capabilities replication."
"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."
"Our users are able to easily roll back snapshots without going through IT."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."
"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"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."
"The most crucial feature of IBM FlashSystem is compression."
"FlashSystem offers proven technology in a compact package."
"IBM FlashSystem is the best solution for storage virtualization."
"The most valuable feature is reliability."
"The most valuable features are flexibility and performance."
"Over the years, it has become increasingly user-friendly."
"The all-flash storage has tier replication capabilities."
"Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."
"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one. You have a peak request on only one node and the others don't do anything."
"Some improvements to the NFS support would be of interest to us."
"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."
"I would like to see increased reporting and statistics functionalities."
"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."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."
"It has room for improvement in the area of stability."
"In the next release having the next level of high-speed performance would be great."
"The interface of this solution could be improved."
"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"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 security features can be improved such that the encryption does not affect performance in any way."
