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 features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."
"Of all the components in our IT system, it's probably the least troublesome."
"This has really changed the way our company can acquire and process data in the field, allowing us to differentiate ourselves against all our competitors."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"The stability of the solution is good."
"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."
"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"Integration with other NetApp solutions and merging them is manageable."
"When it came time to replace, we evaluated EMC, NetApp, IBM again and chose NetApp and have not regretted it."
"Really, I sell only NetApp because I know it and it's really good and very predictable."
"Very stable and very scalable."
"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."
"We feel that NetApp gave us a platform (base) which could clearly arrange all our files and volumes."
"The solution is stable."
"We get our data faster and it's very reliable; we don't go down."
 

Cons

"The pricing could be reduced."
"Data storage performance needs to be improved."
"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"Dell's customer service needs improvement."
"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."
"Dell PowerScale's deployment is not easy."
"Always, there is room for improvement in terms of cybersecurity, as new challenges are continually emerging in 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."
"There may actually be so many features that the end-user gets lost in the volume."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
"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."
"There is room for improvement in the support. It has been a problem for our team."
"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 would like to see the GUI management simplified in the next release."
"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

"Our company finds the pricing high, but it decreases over time."
"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 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."
"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."
"The price of the solution is high."
"Dell PowerScale (Isilon) is an expensive solution."
"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 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 price could be lower."
"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 product is costly."
"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."
"It is an expensive solution."
