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."Dell PowerScale's performance is good."
"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."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"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 solution is stable."
"The flexibility and the user-friendly interface are the most valuable features."
"The stability of the solution is good."
"FlashSystem offers proven technology in a compact package."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"IBM FlashSystem is a stable solution."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"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."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"Data storage performance needs to be improved."
"Some improvements to the NFS support would be of interest to us."
"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 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."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"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."
"Its configuration needs to be more straightforward."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The product needs to improve their scalability."
"The interface of this solution could be improved."
"The array level RAID does not seem available."
"The solution should improve its pricing and the mechanism in the reduction pool."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"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."
"The pricing needs to be more competitive."
