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

"It's helpful that we're able to scale the number of nodes without having to build additional clusters."
"The product's scalability feature is super easy to use."
"This has been a valuable solution for our business overall. It offers business continuity and replication features."
"I appreciate the high-availability data storage feature of Dell PowerScale the most, as it has benefited my organization by improving storage and collapsing technologies, making it easier for the users and aligning with our digital transformation initiatives by collapsing a large environment to a small footprint."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"Customer service has been really good."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"Dell PowerScale aligns with our organization's strategic goals of improving operational efficiency because we are able to provide a centralized location for file systems."
"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."
"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."
"At the moment, we are extensively using SnapMirror."
"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."
"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 is integration."
"Really, I sell only NetApp because I know it and it's really good and very predictable."
"It gave us a platform which could clearly arrange all our files and volumes."
 

Cons

"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."
"The solution lacks a cloud version."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"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."
"In the past year, it hasn't been as great. They seem to just follow KBS."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update."
"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 documentation could be improved."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
"If you overthink provisioning, if you over-allocate, if it gets full, or if something crazy happens and you haven't been watching, then you can lose data."
"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."
"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."
"I'm not sure how easy it is to use on the cloud versus on-prem."
"There may actually be so many features that the end-user gets lost in the volume."
 

Pricing and Cost Advice

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"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."
"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."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The solution's licensing cost varies based on capacity and performance requirements."
"The product is costly."
"In general, I am pleased with the pricing, though it is a little high."
"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,."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"The price could be lower."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
