Featured Reviews

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.
Vincenzo D'Aniello - PeerSpot reviewer
Open-source with great disk management and task synchronization
The system itself allows you to add any feature. The only bad thing is that this maybe depends on FreeBSD, and sometimes finding documentation is difficult. For example, we knew that previous versions automatically enabled the Linux kernel, yet with the recent version, this was no longer the case. Now, there was the possibility of being able to create Debian-based jails, and finding the documentation was not easy or fast. That said, in the end, we succeeded. If you find the documentation, it is always incomplete and fragmented.

Quotes from Members

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

Pros

"The solution's most valuable features are scalability and flexibility."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."
"The most valuable feature is its single space of storage."
"The solution is extremely easy to manage. This is its most valuable feature."
"Dell PowerScale has the SmartConnect and SmartConnect Pro features. That's why I like the product."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."
"Ability to scale the number of nodes without having to build additional clusters."
"It integrates well into either Windows or Linux environments."
"It has the best storage capacity."
"Its stability is the most valuable. It is reliable, and we don't have to worry too much about it."
"The solution has been very stable so far."
"The ease of use of the 'jail', the management of backups, and copies to easily create test and pre-production scenarios have speeded up the development and distribution of business apps."
"FreeNAS is much simpler and easier to use than other solutions, but we don't have the complete range of features that come with the full version."
"What I like about it is that I can work on it from any computer or any device. The initial setup is very simple. The setup wizard is really helpful."
 

Cons

"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."
"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."
"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"Dell PowerScale's deployment is not easy."
"Isilon has limitations on the number of files that can be generated."
"The support offered by the product is an area of concern where improvements are required."
"FreeNAS should be better prepared for clustering."
"The support for S3 needs to be improved."
"They should include clustering for the solution."
"The latest version of the dashboard doesn't work as good as the previous version."
"They can improve the integration with PSA systems. This functionality could be better."
"The one thing that I find difficult to do which is very time-consuming is that I like to have a backup of the important files."
"If you find the documentation, it is always incomplete and fragmented."
 

Pricing and Cost Advice

"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."
"It is a really expensive solution."
"The solution's licensing cost varies based on capacity and performance 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."
"It is an expensive solution."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The pricing for this solution is reasonable."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"For our configuration, we pay a little bit less than €10,000 ($12,000 USD) per year."
"Its price is okay. It suits our needs."
"We use the free version of the program."
"Its licensing cost is based on the hardware capacity."
