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 has the AI to protect the EMA."

"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."

"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."

"The tool comes with cheap disks and works fast for video content."

"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."

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

"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 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."

More Dell PowerScale (Isilon) pros

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

"Very stable and very scalable."

"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."

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

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

"The solution scales well."

"The solution is stable."

Cons

"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS. It would be key if this was made possible."

"I would like to see increased reporting and statistics functionalities."

"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. You have a peak request on only one node and the others don't do anything."

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

"I would want to see more AI features with Dell PowerScale (Isilon)."

"The price of the solution could be reduced."

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

More Dell PowerScale (Isilon) cons

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

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

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

"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."

"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."

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

More NetApp Private Storage cons

Pricing and Cost Advice

"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."

"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."

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

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

"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."

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

"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."

"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,."

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

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

"The product is costly."

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