Manages large data sets efficiently with hybrid cloud integration
My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.

Well-suited for virtualized environments and highly stable solution
We are in a VMware Intra environment, so we are utilizing NetApp Storage for our virtualization infrastructure NetApp offers multiple features that we utilize for our projects. At the moment, we are extensively using SnapMirror Flex. There is room for improvement in the support. It has been a…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The tool's most valuable features are high density and scalability."
"Based on the flexibility of the system itself, it was easy for us to manage the growth by buying individual nodes as needed."
"Dell PowerScale's performance is good."
"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."
"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."
"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."
"Dell has the AI to protect the EMA."
"The tool's most valuable features are scalability and stability."
"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 is integration."
"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."
"As opposed to cloud, we have full control over security, use, who uses it. We own a number of different companies, so we can partition however we want."
"At the moment, we are extensively using SnapMirror."
"Integration with other NetApp solutions and merging them is manageable."
"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."
"The solution scales well."
 

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."
"The solution can be a bit complex for those not well versed in the technology."
"They could improve implementation, as we had to rack and stack it ourselves."
"I would want to see more AI features with Dell PowerScale (Isilon)."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"I would make Dell PowerScale (Isilon) better by improving SmartSync in the graphical user interface. Currently, everything has to be done through the command line, and I prefer having a graphical interface."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"There may actually be so many features that the end-user gets lost in the volume."
"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 would like to have the Active-Active feature. Some competitors already have it. I would like NetApp to add it to stay competitive."
"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 hardware does not last as long as it could with new software."
"The users find the new version's GUI complicated to use."
"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."
"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

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."
"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."
"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."
"Our company finds the pricing high, but it decreases over time."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"The product is costly."
"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 price could be lower."
