Find out in this report how the two NAS solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"The stability of the solution is good."
"The flexibility and the user-friendly interface are the most valuable features."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"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."
"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."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"The speed of the unit is its best feature. It performs very well."
"The initial customer technical support was efficient and effective."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"The most valuable features are deduplication and compression."
"The GUI is very easy and performance is also good."
"We've found the solution to be very stable so far."
"Dell PowerScale's deployment is not easy."
"Dell PowerScale needs to reduce its price."
"It is a bit higher priced than some of the other systems."
"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."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"Its configuration needs to be more straightforward."
"I would like to see increased reporting and statistics functionalities."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."
"Events/log analysis tools."
"I would like to see an improvement in the handling of large amounts of rights."
"Our model does not support compression or deduplication."
"The installation is not easy. You need to have extensive knowledge to handle it."
