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

"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."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"The technical support has been excellent. I would give them a ten out of ten for support."
"Its scalability has been huge for us."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"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."
"PowerScale is one of those things that will grow in your environment; once you start it with one thing, you'll learn that it can do much more, very quickly."
"Overall, Dell PowerScale (Isilon) has made the management of the data and networks easier."
"The solution is stable."
"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."
"We get our data faster and it's very reliable; we don't go down."
"In terms of quality and uptime, it is the thing to have."
"It gave us a platform which could clearly arrange all our files and volumes."
"The most valuable feature is integration."
"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."
"If your company has the budget for NetApp Private Storage I would recommend it."
 

Cons

"The UID mapping and how to configure mapping-related things is a struggle."
"The pricing could be reduced."
"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."
"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."
"The portal is really complicated to figure out features and functions, and it could be easier to navigate."
"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."
"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."
"The solution isn't suitable for small environments or small customers."
"It is not the fastest storage solution."
"I would like to see the GUI management simplified in the next release."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
"There is room for improvement in the support. It has been a problem for our team."
"The one thing I've noticed with NetApp when you buy hardware and you can use it for a while and then you have to get new hardware."
"There may actually be so many features that the end-user gets lost in the volume."
"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 think that it should work better with Microsoft solutions, more integrated with Microsoft. We also need integrated NAS and block storage."
 

Pricing and Cost Advice

"Dell PowerScale (Isilon) is an expensive solution."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"The price of the solution is high."
"In general, I am pleased with the pricing, though it is a little high."
"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."
"It is an expensive solution."
"The price could be lower."
"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."
