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 most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."

"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."

"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."

"Dell has the AI to protect the EMA."

"The tool's most valuable features are high density and scalability."

"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."

"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."

More Dell PowerScale pros

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

"Very stable and very scalable."

"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware."

"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 beauty is it's worth it."

"In terms of quality and uptime, it is the thing to have."

"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."

"Really, I sell only NetApp because I know it and it's really good and very predictable."

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 solution’s interface and pricing could be improved."

"The UID mapping and how to configure mapping-related things is a struggle."

"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."

"The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."

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

"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."

"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."

More Dell PowerScale cons

"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."

"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."

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

"This product is probably one of the most complex to set up on the market."

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

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

"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 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."

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

"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."

"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."

"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."

More Dell PowerScale 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."

"It is an expensive solution."

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

"The price could be lower."

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

"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."
