We performed a comparison between Dell PowerScale (Isilon) and Qumulo 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."The solution is extremely easy to manage. This is its most valuable feature."
"I don't have to rebuild the cluster to add a node."
"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."
"Its most valuable feature is the DR capabilities replication."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"The stability of the solution is good."
"Dell PowerScale's performance is good."
"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."
"The data protection algorithm to protect the data between the nodes has been the most valuable feature. The integration with backup platforms such as Veeam and Veritas has also been valuable."
"The most valuable feature is real-time analytics."
"The most valuable features of Qumulo are the ease of management and special permissions that are quick to enable. The overall performance of the solution is good."
"The feature that I like most is the analytics part of the file system."
"The most valuable feature of Qumulo is the ability to share files and reliability."
"The ratio of total operational cost to complexity versus feature set is very good."
"It is a very stable product. I never faced any issues."
"The most valuable features of Qumulo are its rolling updates and all-day availability."
"The replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement."
"There is room for improvement in its handling of object storage."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."
"Isilon has limitations on the number of files that can be generated."
"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."
"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."
"It is a bit higher priced than some of the other systems."
"The solution can be a bit complex for those not well versed in the technology."
"In the next release, I would like to see the ability to have more control at a terminal level of the file system."
"The price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"Qumulo should continue to expand automation and orchestration capabilities."
"In the future, I would like to see non-disruptive updates."
"One aspect of Qumulo that I hoped to see improved was its software upgrade process, which did see significant progress during my usage. Initially, upgrading the software resulted in several minutes of system downtime. However, by the time I departed last summer, the downtime had reduced to mere ten seconds. Although I am unsure if Qumulo has yet achieved a completely outage-free upgrade, I simply performed the upgrades early in the morning before the marketing department began its workday, so any downtime was inconsequential."
"Some anti-theft permissions do not transfer well to Qumulo."
"The support for iMac and protocols should be improved, not all features are available."
"The solution could improve availability and improve data protection or data services such as compression of deduplication. In a future release, we'd like to have more cloud API integrations."
