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

"Eyeglass is used to monitor for malware, which is very useful for us."
"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."
"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 extremely easy to manage. This is its most valuable feature."
"I don't have to rebuild the cluster to add a node."
"The tool's most valuable features are scalability and stability."
"The maintenance is very good, and the deployment is straightforward as well."
"My advice to other companies considering Dell PowerScale (Isilon) is that it takes a little time to understand the product, but once you have it set up and running, it will run stable for all its lifetime."
"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."
"The solution is stable."
"For recording and stability, NetApp Private Storage is the best."
"At the moment, we are extensively using SnapMirror."
"Really, I sell only NetApp because I know it and it's really good and very predictable."
"The most valuable feature is integration."
"We get our data faster and it's very reliable; we don't go down."
"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

"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."
"Data storage performance needs to be improved."
"One downside of Dell PowerScale (Isilon) is that it is really complicated to configure."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"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."
"Backward compatibility is something Dell PowerScale (Isilon) could work on."
"My experience with pricing, setup cost, and licensing for Dell PowerScale has been expensive."
"An improvement of that technology when it comes to DR implementations is something that I would look to see in the future. It is there, but it is not 100% in a way that is easy to implement."
"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 solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
"The users find the new version's GUI complicated to use."
"The hardware does not last as long as it could with new software."
"There may actually be so many features that the end-user gets lost in the volume."
"I would like to see the GUI management simplified in the next release."
"There is room for improvement in the support. It has been a problem for our team."
"This product is probably one of the most complex to set up on the market."
 

Pricing and Cost Advice

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"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."
"Pricing for this solution is reasonable."
"Our company finds the pricing high, but it decreases over time."
"It is an expensive solution."
"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."
"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"It is an expensive solution."
"In general, I am pleased with the pricing, though it is a little high."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
