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."Our users are able to easily roll back snapshots without going through IT."
"The solution provides massive performance, scalability, efficiency, and ease of management."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"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."
"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"There are also the policies that you set up on replication and purging files, and policies for something called WORM. That's a "write once, read many," where you can't overwrite certain files or certain data. It puts them in a "protected mode" where it becomes very difficult for someone to accidentally delete. We use that for certain files or certain directories, because we're dealing with video and some video has to be protected for chain-of-custody purposes. The WORM feature works great."
"The most valuable feature we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server"
"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."
"The most valuable features of Qumulo are its rolling updates and all-day availability."
"It is a very stable product. I never faced any issues."
"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 feature that I like most is the analytics part of the file system."
"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 most valuable feature is real-time analytics."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"Dell PowerScale needs to reduce its price."
"I would like to see increased reporting and statistics functionalities."
"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."
"The solution's rate structure or rate redundancy needs to be improved."
"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."
"Qumulo should continue to expand automation and orchestration capabilities."
"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 price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"In the next release, I would like to see the ability to have more control at a terminal level of the file system."
"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."
"In the future, I would like to see non-disruptive updates."
