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

"Dell PowerScale (Isilon) helps improve the way the organization functions through massive scalability, high performance, a single file system, high availability and reliability, flexible protocols, support for NFS, SMB, HDFS, strong security, cloud integration, efficiency, data protection, snapshot, queue, and sync queue, optimized for unstructured data."

"The solution allows me to use SSMDS to store data for end users and share it within different locations."

"It is stable and very user-friendly."

"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."

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

"This has been a valuable solution for our business overall. It offers business continuity and replication features."

"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."

"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."

More Dell PowerScale (Isilon) pros

"NetApp is faster than other storage brands."

"We get our data faster and it's very reliable; we don't go down."

"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, and the connector that comes with the solution that allows connection back to the Cisco SAN switches is very good."

"Very stable and very scalable."

"Disaster recovery. And I like the security very much. I think they have the needed options for security. Can manage NPS using the same tools and process that we use today."

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

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

"The solution is stable."

More NetApp Private Storage pros

Cons

"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."

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

"We have had issues with internal load balancing between some of the shelves. That is an ongoing issue that support is trying to address."

"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."

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

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

"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."

More Dell PowerScale (Isilon) cons

"If you overthink provisioning, if you over-allocate, if it gets full, or if something crazy happens and you haven't been watching, then you can lose data."

"The price could be lower."

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

"The documentation could be improved."

"I'm not sure how easy it is to use on the cloud versus on-prem."

"It is not the fastest storage solution."

"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."

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

More NetApp Private Storage cons

Pricing and Cost Advice

"The pricing for this solution is reasonable."

"Our company finds the pricing high, but it decreases over time."

"Pricing for this solution is reasonable."

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

"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."

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

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

"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."

More Dell PowerScale (Isilon) pricing and cost advice

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

"It is an expensive solution."

"The product is costly."

"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,."

"The price could be lower."
