Executive SummaryUpdated on Nov 7, 2024

Dell PowerScale and NetApp Private Storage are prominent in the storage category, each offering notable benefits. Dell PowerScale stands out for its scalability and ease of management, providing enhanced features while requiring minimal IT resources. This advantage is highlighted by superior user feedback on scalability and support.

Features: Dell PowerScale offers key features such as policy-based file placement, SmartQuotas, and InsightIQ, enhancing storage utility and performance. The system supports scalable access from multiple hardware platforms, and continual OS improvements come without new licensing, making it a comprehensive storage solution. NetApp’s unified storage system is highly flexible with strong integration capabilities, providing backwards compatibility and robust cloud integration features.

Room for Improvement: Dell PowerScale could improve cloud integration with easier updates and more node options for smaller offices. Enhancements to the WORM feature and InsightIQ’s reporting are also needed, as well as expanding HTTP data protection. NetApp should focus on simplifying configuration and addressing support challenges. Making licensing less complicated would also be beneficial for user satisfaction.

Ease of Deployment and Customer Service: Dell PowerScale and NetApp Private Storage primarily support on-premises deployment, with Dell PowerScale proving more adaptable to hybrid cloud environments. Dell’s technical support is generally well-regarded, though some users experience initial assistance challenges. NetApp support is inconsistent, often requiring escalation to resolve issues satisfactorily.

Pricing and ROI: Both Dell PowerScale and NetApp Private Storage are perceived as costly, but Dell's flexible licensing and comprehensive features offer a compelling ROI. Dell users find value in long-term cost efficiency and reduced administrative workload, while NetApp users appreciate reliability and integration, despite finding the pricing steep.

Flexibility and reliability have supported seamless data growth

I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

Has supported continuous broadcasting with reliable performance and consistent operations

They can make more solutions for cloud integration in NetApp Private Storage. It should be easier to use the cloud S3 integration, maybe from a NetApp interface, where users can choose the type of storage before sending to S3. I would like to see more audit and performance logs via cloud integrations and ONTAP. Without the need for separate software.

Quotes from Members

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

Pros

"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."

"We use the solution internally to support our own managed servers and run our own support center."

"The most valuable features of the solution are flexibility and ease of implementation."

"I assess the stability and reliability of Dell PowerScale (Isilon) as perfect, as we haven't had any hiccups with it so far."

"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product."

"I can certainly recommend PowerScale for mission-critical workloads, it is a powerful but simple platform with little administration overhead."

"The tool's most valuable features are scalability and stability."

"PowerScale is one of those things that will grow in your environment; once you start it with one thing, you'll learn that it can do much more, very quickly."

More Dell PowerScale (Isilon) pros

"The most valuable feature is integration."

"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware. That's the beauty of NetApp's operating system."

"If your company has the budget for NetApp Private Storage I would recommend it."

"For recording and stability, NetApp Private Storage is the best."

"Very stable and very scalable."

"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."

"Integration with other NetApp solutions and merging them is manageable."

"Its flexibility and ability to configure volumes is its most valuable aspect; I have no problem configuring the product for different kinds of use cases and configuring throughput or configuring some kind of logical volumes and so on."

More NetApp Private Storage pros

Cons

"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS."

"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in the market."

"They could improve implementation, as we had to rack and stack it ourselves."

"Backward compatibility is something Dell PowerScale (Isilon) could work on."

"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."

"The biggest weakness is small file handling."

"Some improvements to the NFS support would be of interest to us."

"The replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement."

More Dell PowerScale (Isilon) cons

"It is not the fastest storage solution."

"I think that it should work better with Microsoft solutions, more integrated with Microsoft. We also need integrated NAS and block storage."

"I would like to see the GUI management simplified in the next release."

"The hardware does not last as long as it could with new software."

"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."

"There is room for improvement in the support. It has been a problem for our team."

"This product is probably one of the most complex to set up on the market."

"I would like to have the Active-Active feature. Some competitors, like Nutanix, already have it."

More NetApp Private Storage cons

Pricing and Cost Advice

"It is an expensive product with a high storage capacity suitable for large data requirements."

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

"The price of Dell PowerScale (Isilon) is reasonable."

"Dell PowerScale (Isilon) is an expensive solution."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"It is an expensive solution."

"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."

"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."

More Dell PowerScale (Isilon) pricing and cost advice

"The product is costly."

"The price could be lower."

"In general, I am pleased with the pricing, though it is a little high."

"It is an expensive solution."

"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."

"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."

"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
