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 allows me to use SSMDS to store data for end users and share it within different locations."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"Dell PowerScale's performance is good."
"The solution is stable."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"The tool comes with cheap disks and works fast for video content."
"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."
"The tool's most valuable features are scalability and stability."
"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."
"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."
"It has the best storage capacity."
"It integrates well into either Windows or Linux environments."
"The solution has been very stable so far."
"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."
"Its stability is the most valuable. It is reliable, and we don't have to worry too much about it."
 

Cons

"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."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."
"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."
"I would like to see increased reporting and statistics functionalities."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"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’s interface and pricing could be improved."
"If you find the documentation, it is always incomplete and fragmented."
"FreeNAS should be better prepared for clustering."
"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."
"They should include clustering for the solution."
"They can improve the integration with PSA systems. This functionality could be better."
"The latest version of the dashboard doesn't work as good as the previous version."
"The support for S3 needs to be improved."
 

Pricing and Cost Advice

"It is a really expensive solution."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"Pricing for this solution is reasonable."
"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 price of Dell PowerScale (Isilon) is reasonable."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The price of the solution is high."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"Its licensing cost is based on the hardware capacity."
"We use the free version of the program."
