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.

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 for me is SyncIQ."
"The most valuable feature of Dell PowerScale is its scalability."
"We use the solution internally to support our own managed servers and run our own support center."
"Overall, the hardware itself, and the OneFS file system, are the best selling points, combined with the delivery and the installation."
"The features of Dell PowerScale (Isilon) that I prefer the most include some of the newer technologies that are on it, which would include SmartSync and the ability for the data mover to continue to make incremental changes."
"I can certainly recommend PowerScale for mission-critical workloads, it is a powerful but simple platform with little administration overhead."
"Dell has the AI to protect the EMA."
"The most valuable feature we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server"
"They have the scalability that we need, that we ask for, and I think it is a very, very good solution."
"NetApp is faster than other storage brands."
"At the moment, we are extensively using SnapMirror."
"In terms of quality and uptime, it is the thing to have."
"Integration with other NetApp solutions and merging them is manageable."
"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."
"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."
"The solution scales well."
 

Cons

"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."
"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."
"There is room for improvement in its handling of object storage."
"The cost of Dell PowerScale is currently high and there is room for improvement."
"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 initial setup for this solution is complex."
"The UID mapping and how to configure mapping-related things is a struggle."
"Beyond containerized storage support and software updating, I have had very bad experiences with Dell PowerScale (Isilon) because they present more issues than other storage options, even when compared with NetApp."
"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'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 would like to see the GUI management simplified in the next release."
"The hardware does not last as long as it could with new software."
"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."
"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."
"They need a little more technical people in Akola."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
 

Pricing and Cost Advice

"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The pricing for this solution is reasonable."
"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"It is a really expensive solution."
"The product is costly."
"It is an expensive solution."
"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,."
"In general, I am pleased with the pricing, though it is a little high."
"The price could be lower."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
