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

"My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
"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."
"Dell PowerScale overall is easy to use."
"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."
"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"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."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product."
"NetApp is faster than other storage brands."
"For recording and stability, NetApp Private Storage is the best."
"They have the scalability that we need, that we ask for, and I think it is a very, very good solution."
"Really, I sell only NetApp because I know it and it's really good and very predictable."
"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."
"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."
"Very stable and very scalable."
"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."
 

Cons

"Pricing is an issue. It's quite expensive for the amount of storage we have."
"The initial setup for this solution is complex."
"The pricing is expensive, but I think it's a fair value because it does manage itself."
"Isilon has limitations on the number of files that can be generated."
"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 solution’s interface and pricing could be improved."
"PowerScale is not suitable for virtual environments."
"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."
"This product is probably one of the most complex to set up on the market."
"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."
"The documentation could be improved."
"I'm not sure how easy it is to use on the cloud versus on-prem."
"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."
"It is not the fastest storage solution."
"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."
"I would like to have the Active-Active feature. Some competitors, like Nutanix, already have it."
 

Pricing and Cost Advice

"It is a really expensive solution."
"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."
"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."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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."
"The pricing is excellent."
"The pricing for this solution is reasonable."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
"The price could be lower."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"The product is costly."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"In general, I am pleased with the pricing, though it is a little high."
"It is an expensive solution."
