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

"The solution's most valuable features are scalability and flexibility."

"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."

"Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard."

"Customer service has been really good."

"The most valuable feature for me is SyncIQ."

"The product's scalability feature is super easy to use."

"With Dell PowerScale (Isilon), it uses not just a terabyte but petabytes of data, storing a large amount of data takes within minutes, and you can bring it down to seconds as well, as it does not take much time to upload or copy the data here and there, and upgrades also do not take much time."

"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."

More Dell PowerScale (Isilon) pros

"NetApp is faster than other storage brands."

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

"The solution scales well."

"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."

"It gave us a platform which could clearly arrange all our files and volumes."

"NetApp has really added a lot of features over the years to improve the product and performance. They can do things now like control ingress. They can control egress."

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

More NetApp Private Storage pros

Cons

"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."

"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."

"The solution is expensive. It's quite expensive for the amount of storage we have."

"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."

"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."

"The product’s expansion capacity, pricing clarity, and ease of use need improvement."

"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."

"Improvements could be made on the object storage side."

More Dell PowerScale (Isilon) cons

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

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

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

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

"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."

"I would like to have the Active-Active feature. Some competitors already have it. I would like NetApp to add it to stay competitive."

"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."

"They need a little more technical people in Akola. Most of the NetApp people are in Bangalore, Mumbai, or Delhi, but there are very few in Akola. I think NetApp has few technicians in Akola because they mostly rely on partners to service this area."

More NetApp Private Storage cons

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."

"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 product with a high storage capacity suitable for large data requirements."

"The solution's licensing cost varies based on capacity and performance requirements."

"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."

"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."

"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."

More Dell PowerScale (Isilon) pricing and cost advice

"The price could be lower."

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

"It is an expensive solution."

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

"The product is costly."

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

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