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 most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"The solution is stable."
"The features of Dell PowerScale (Isilon) that I prefer the most include some of the newer technologies that are on it, which would include SmartSync and the ability for the data mover to continue to make incremental changes."
"Overall, the hardware itself, and the OneFS file system, are the best selling points, combined with the delivery and the installation."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"The major advantages include data protection, ransomware protection, and cloud capabilities, and the primary advantage is the ability to use the entire cluster in one unified file system, which is a feature I have not observed in other products."
"We get our data faster and it's very reliable; we don't go down."
"The solution scales well."
"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."
"At the moment, we are extensively using SnapMirror."
"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."
"Very stable and very scalable."
"The beauty is it's worth it."
"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."
 

Cons

"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"Some improvements to the NFS support would be of interest to us."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"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."
"The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."
"The price of the solution could be reduced."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"It is a bit higher priced than some of the other systems."
"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."
"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."
"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."
"I would like to have the Active-Active feature. Some competitors, like Nutanix, already have it."
"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."
"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."
"The users find the new version's GUI complicated to use."
 

Pricing and Cost Advice

"Pricing for this solution is reasonable."
"The price of Dell PowerScale (Isilon) is reasonable."

"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."
"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"It is an expensive solution."
"The pricing for this solution is reasonable."
"It is an expensive solution."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
