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 solution's most valuable features are scalability and flexibility."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"The solution is extremely easy to manage. This is its most valuable feature."
"Of all the components in our IT system, it's probably the least troublesome."
"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 flexibility and the user-friendly interface are the most valuable features."
"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"It is stable and very user-friendly."
"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."
"The solution scales well."
"If your company has the budget for NetApp Private Storage I would recommend it."
"The solution is stable."
"NetApp is faster than other storage brands."
"For recording and stability, NetApp Private Storage is the best."
"When it came time to replace, we evaluated EMC, NetApp, IBM again and chose NetApp and have not regretted it."
"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."
 

Cons

"The biggest weakness is small file handling."
"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."
"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."
"The solution's rate structure or rate redundancy needs to be improved."
"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."
"Dell PowerScale's deployment is not easy."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"It is not the fastest storage solution."
"There is room for improvement in the support. It has been a problem for our team."
"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'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 need a little more technical people in Akola."
"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. 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."
"The price could be lower."
 

Pricing and Cost Advice

"Dell PowerScale (Isilon) is an expensive solution."
"It is an expensive solution."
"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."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"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 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."
"It is an expensive solution."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
"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."
"The product is costly."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"The price could be lower."
