Simplified data management, tremendously reducing our users’ cognitive overhead
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. You can either access a file because it can be access by anyone in the organization, or you cannot at all. There is no in-between. HTTP is not considered a first-class data access protocol, so the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply. However, with the recent introduction of S3 starting from OneFS 9, I believe the necessary plumbing is already there for HTTPS to also be elevated to a first-class protocol in the future because both protocols sit behind a web server under the hood. It does not sound like it would be too complicated to implement, but it would be a valuable feature and it is currently missing.

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 stability of the solution is good."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"The most valuable feature of Dell PowerScale is its scalability."
"The solution's most valuable features are scalability and flexibility."
"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."
"The tool comes with cheap disks and works fast for video content."
"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."
"Very stable and very scalable."
"Integration with other NetApp solutions and merging them is manageable."
"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."
"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."
"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."
"The solution is stable."
 

Cons

"Some improvements to the NFS support would be of interest to us."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"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."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"PowerScale is not suitable for virtual environments."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"The price of the solution could be reduced."
"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."
"The users find the new version's GUI complicated to use."
"There may actually be so many features that the end-user gets lost in the volume."
"The hardware does not last as long as it could with new software."
"It is not the fastest storage solution."
"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."
"There is room for improvement in the support. It has been a problem for our team."
"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."
 

Pricing and Cost Advice

"The solution's licensing cost varies based on capacity and performance requirements."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"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 pricing for this solution is reasonable."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"Dell PowerScale (Isilon) is an expensive solution."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"It is an expensive solution."
"The price could be lower."
"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 product is costly."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
