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

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

"The most valuable feature of the solution is its performance."

"I buy Dell PowerScale (Isilon) because of the price, service, and technology, and the technology that is particularly good for my company is that I have two Dell PowerScale (Isilon) systems in two sites, and I use replication between them with Superna software, which is a third-party Dell technology."

"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."

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

"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."

"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."

"I would rate Dell PowerScale (Isilon) as a product a ten out of ten."

More Dell PowerScale (Isilon) pros

"The solution scales well."

"The most valuable feature of NetApp Private Storage is out-of-the-box integration with the SAN switches. They are much easier compared to Dell solutions. Additionally, the connector that comes with the solution that allows connection back to the Cisco SAN switches is very good. In Dell, I would need to use an FCIP or CIP port that is required."

"NetApp is faster than other storage brands."

"As opposed to cloud, we have full control over security, use, who uses it. We own a number of different companies, so we can partition however we want."

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

"The solution is stable."

"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."

"Very stable and very scalable."

More NetApp Private Storage pros

Cons

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

"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."

"We had some issues with level 1 support. We had to fight with them on repeated issues. There is room for improvement in level 1 support."

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

"We used to have a chat feature available on the support site. It's not available to us anymore."

"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."

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

"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."

More Dell PowerScale (Isilon) cons

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

"There may actually be so many features that the end-user gets lost in the volume."

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

"It is not the fastest storage solution."

"I'm not sure how easy it is to use on the cloud versus on-prem. If they have different user experiences, they should work to make the two as similar as possible to make it easy for a user to understand both even if they only deal mainly with one."

"The users find the new version's GUI complicated to use."

"We had to write a number of custom tools or scripts ourselves to use it as a staging area between our on-premises datacenter and our cloud installation."

"NetApp Private Storage is still integrated into the ISCSI connectivity and the FC protocol. I would recommend them to migrate to the FCIP because the SAN switches are moving further to an FCIP, and are scaling out of the ISCSI connectivity. Sooner or later, that will be an issue for NetApp Private Storage. An NFCIP should be available to them moving three years down the line."

More NetApp Private Storage cons

Pricing and Cost Advice

"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 the solution is high."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

"The pricing is excellent."

"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."

"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."

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

"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."

More Dell PowerScale (Isilon) pricing and cost advice

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

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

"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."
