Eric Burgueño - PeerSpot reviewer
Simplified data management, tremendously reducing our users’ cognitive overhead
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. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.
VinceVitro - PeerSpot reviewer
Useful data sharing, simple cluster scaling, and excellent support
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"The most valuable feature of Dell PowerScale is its scalability."
"The most valuable feature is its single space of storage."
"Dell PowerScale has the SmartConnect and SmartConnect Pro features. That's why I like the product."
"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."
"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 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."
"The solution's scalability is very good."
"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 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 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 of Qumulo is the ability to share files and reliability."
"The most valuable feature is real-time analytics."
"The most valuable features of Qumulo are its rolling updates and all-day availability."
 

Cons

"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."
"Data storage performance needs to be improved."
"The solution can be a bit complex for those not well versed in the technology."
"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them. We had old hard drives with moving parts in Dell PowerScale, and due to this, we must switch to a more efficient environment with all-flash."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"It would be good to have synchronized mirroring between two clusters without using a third-party program."
"The price of the solution could be reduced."
"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."
"The support for iMac and protocols should be improved, not all features are available."
"Some anti-theft permissions do not transfer well to Qumulo."
"Qumulo should continue to expand automation and orchestration capabilities."
"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."
"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."
"In the future, I would like to see non-disruptive updates."
"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."
 

Pricing and Cost Advice

"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"The solution's licensing cost varies based on capacity and performance requirements."
"The price of Qumulo is reasonable."
"The price of the solution is in the middle range compared to others. We look at the price per terabyte."
