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."

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

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

"I rate Dell PowerScale (Isilon) a ten out of ten, and we continue to keep buying it."

"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."

"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."

"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."

"My experience when deploying Dell PowerScale (Isilon) was very straightforward, as we had Dell come on site to do all the actual setup, which was a big help."

More Dell PowerScale (Isilon) pros

"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."

"NetApp is faster than other storage brands."

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

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

"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."

"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."

"The solution is stable."

Cons

"We lost our technical sales reps about two years ago. We haven't gotten one assigned to us and we'd love to have one."

"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."

"Dell PowerScale's deployment is not easy."

"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."

"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."

"It is a bit higher priced than some of the other systems."

"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 price always has room for improvement."

More Dell PowerScale (Isilon) cons

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

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

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

"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 see the GUI management simplified in the next release."

"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."

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

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

More NetApp Private Storage cons

Pricing and Cost Advice

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

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

"The pricing is excellent."

"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."

"Pricing for this solution is reasonable."

"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."

"It is a really expensive solution."

"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."

More Dell PowerScale (Isilon) pricing and cost advice

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

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

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

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

"It is an expensive solution."

"The product is costly."

"The price could be lower."
