Operates seamlessly and minimizes downtime while meeting enterprise file share demands
The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed. These features benefit my company by providing less downtime and less overhead. While I have not calculated an exact number regarding the reduction in downtime, we have always been using the product, so we have no baseline to compare it to. However, it is a very good product. Dell PowerScale (Isilon) scales very well with the growing needs of my company.

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 capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."
"Dell PowerScale is very stable and scalable; when you are working at one hundred percent capacity without issues, I trust the product, the software, and the infrastructure here."
"Dell PowerScale overall is easy to use."
"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."
"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."
"The solution's flexibility for supporting various data workloads while keeping them protected is great."
"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."
"Regarding stability, I find no lagging, crashing, or downtime with Dell PowerScale (Isilon), and it is a highly scalable, stable, and reliable solution that I have experienced."
"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."
"NetApp is faster than other storage brands."
"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."
"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware."
"We get our data faster and it's very reliable; we don't go down."
"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."
"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."
"Very stable and very scalable."
 

Cons

"The downside of Dell PowerScale (Isilon) is that if we are replacing a drive, sometimes in the worst-case scenarios, some of the other drives will also go to the SmartFail state."
"A recent development is, that there's a key feature coming out in OneFS 9.3, however, when you then try to get to 9.3 or 9.4 of the OneFS, it's been pulled from the download of the Dell website and we're referring back to 9.2.1 as the target code."
"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."
"The pricing is expensive, but I think it's a fair value because it does manage itself."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update."
"The solution’s interface and pricing could be improved."
"They should add some new services that should be for on-premises, and more analytics should be there for the data, allowing for a deep dive from that analytics, which is currently missing."
"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going. That's a little bit of a ding that we have on it. It does so much magic in order to protect itself from drive failures or multiple drive failures, that it automatically handles the provisioning and storage of your data. But by doing that, finding out why a file of a certain size, or a directory of a certain size, is using more storage than is being reported in InsightIQ, is very difficult to discern."
"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."
"The documentation could be improved."
"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."
"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. Sooner or later, that will be an issue for NetApp Private Storage. An NFCIP should be available to them moving three years down the line."
"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."
 

Pricing and Cost Advice

"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."
"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."
"The price of the solution is high."
"Our company finds the pricing high, but it decreases over time."
"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"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."
"It is an expensive solution."
"The product is costly."
"In general, I am pleased with the pricing, though it is a little high."
