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."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."
"The most valuable feature of the solution is its performance."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"I don't have to rebuild the cluster to add a node."
"The tool comes with cheap disks and works fast for video content."
"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."
"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."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"No queuing and high ops, speed, and performance."
"The most valuable features of IBM FlashSystem are performance and security."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"IBM FlashSystem has been stable in our operations."
"The solution’s interface and pricing could be improved."
"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."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"There is room for improvement in its handling of object storage."
"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."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"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."
"The solution can be a bit complex for those not well versed in the technology."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"The marketing could be improved."
"The interface of this solution could be improved."
"The solution is not able to replicate data in one-to-many scenario."
"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure. If IBM could create, or include snapshot management within the GUI, that would really be helpful."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"The storage capacity of this solution could be improved."
