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.

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 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."

"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."

"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."

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

"PowerScale, in our infrastructure, is really a winning piece because today we have three times the performance on the I/O at an affordable price while greatly improving the performance and reliability of our HPC storage."

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

"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."

"Dell PowerScale (Isilon) actually combined a shared file system that scales seamlessly and works effectively, making the blocking and tackling exactly what was advertised."

More Dell PowerScale (Isilon) pros

"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."

"NetApp is faster than other storage brands."

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

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

"The solution is stable."

"At the moment, we are extensively using SnapMirror."

"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."

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

More NetApp Private Storage pros

Cons

"It would be good to have synchronized mirroring between two clusters without using a third-party program."

"The solution’s interface and pricing could be improved."

"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one."

"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."

"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."

"The pricing could be reduced."

"Data storage performance needs to be improved."

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them. We had old hard drives with moving parts in Dell PowerScale, and due to this, we must switch to a more efficient environment with all-flash."

More Dell PowerScale (Isilon) cons

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

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

"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 one thing I've noticed with NetApp when you buy hardware and you can use it for a while and then you have to get new hardware."

"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."

"It is not the fastest storage solution."

"The documentation could be improved."

"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 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."

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

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

"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 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."

"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 the solution is high."

"The pricing for this solution is reasonable."

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."

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

"The product is costly."

"It is an expensive solution."

"The price could be lower."

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