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

"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."

"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 product's scalability feature is super easy to use."

"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."

"The ease of use of this solution has been the most valuable aspect as well as the SyncIQ and snapshot features."

"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."

"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."

"Eyeglass is used to monitor for malware, which is very useful for us."

More Dell PowerScale pros

"We get our data faster and it's very reliable; we don't go down."

"Its flexibility and ability to configure volumes is its most valuable aspect; I have no problem configuring the product for different kinds of use cases and configuring throughput or configuring some kind of logical volumes and so on."

"The most valuable feature is integration."

"Really, I sell only NetApp because I know it and it's really good and very predictable."

"At the moment, we are extensively using SnapMirror."

"They have the scalability that we need, that we ask for, and I think it is a very, very good solution."

"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."

"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."

More NetApp Private Storage pros

Cons

"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."

"In the past year, it hasn't been as great. They seem to just follow KBS."

"Pricing is an issue. It's quite expensive for the amount of storage we have."

"The solution can be a bit complex for those not well versed in the technology."

"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."

"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."

"It would be good to have synchronized mirroring between two clusters without using a third-party program."

"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."

More Dell PowerScale cons

"The hardware does not last as long as it could with new software."

"They need a little more technical people in Akola."

"The users find the new version's GUI complicated to use."

"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."

"They need a little more technical people in Akola. Most of the NetApp people are in Bangalore, Mumbai, or Delhi, but there are very few in Akola. I think NetApp has few technicians in Akola because they mostly rely on partners to service this area."

"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."

"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."

"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."

More NetApp Private Storage cons

Pricing and Cost Advice

"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."

"Our company finds the pricing high, but it decreases over time."

"The pricing for this solution is reasonable."

"Pricing for this solution is reasonable."

"The price of Dell PowerScale (Isilon) is reasonable."

"The price of the solution is high."

"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 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."

More Dell PowerScale pricing and cost advice

"In general, I am pleased with the pricing, though it is a little high."

"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."

"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 price could be lower."
