Helps reduce data silos, improves performance, and flexibility
Our customers have seen improvement in performance, space, and flexibility for growth and management of data protection through snapshots and other systems. The AI models are something we are looking forward to trying but are not there yet. The algorithms are specific to each company and their industry. One of the most important things is the data localization. Many scenarios require the project data traffic to be close to where it is generated and read. A lot of interaction is between users and systems. So data localization is one of the most important things in terms of using the data algorithm. We don't need to manage our PowerScale and run its storage from any location yet but it is something that is coming for sure because several customers have centralized data in main data centers. But in different locations across the globe. So this is going to be a topic. I think that through the different functionalities that the Dell platform can grant, it will be a great player. When it comes to the flexibility for supporting various data workloads while protecting them, the combination of PowerScale and PPDM and all the other components of the data protection solution right now is key. So the automatic integration between the products is one of the killer features of the solution itself. PowerScale helped us to reduce data silos. This has simplified the management of large data environments in terms of scalability and management instead of having a different solution for the right reports to see how the data evolves and how to better manage them. PowerScale can do that in combination with the other components of the ecosystem. In terms of risk reduction, We need to mention the data management and the recovery part, So of course, the integration with the data domain is key. The fact that we can rely on these functions, and the fact that we also manage different customers, and possess the recovery plans and tests that can prove the solution is working.

A high-performing and scalable solution that improves data performance for S3 workloads
We use the solution for S3 storage and Kubernetes backup FlashBlade is so much easier to use than the previous solution; it reduced the time to market to serve our customers. I like the way it streams data performance for S3 workloads and object workloads. FlashBlade could improve its…

Quotes from Members

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


"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."
"The most valuable feature of the solution is its performance."
"The solution's most valuable features are scalability and flexibility."
"The solution is extremely easy to manage. This is its most valuable feature."
"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."
"The most valuable features of the solution are flexibility and ease of implementation."
"The stability of the solution is good."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."
"The most valuable features are the Metro clustering, and disaster recovery."
"The onboarding and integrated monitoring tools are pretty good."
"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."
"The initial setup is pretty quick."
"The product is scalable and easy to expand."


"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."
"Some improvements to the NFS support would be of interest to us."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"It would be nice to see tools like Superna Eyeglass built into PowerScale."
"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."
"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."
"Its configuration needs to be more straightforward."
"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."
"The feature that we're waiting on is better integration with the cell services."
"Pure Storage FlashBlade should improve on more cloud integration."
"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."
"I would like to see more monitoring capability included in the next release of this solution."
"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."
"I would like to see more deduplication."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

Pricing and Cost Advice

"The price of the solution is high."
"The solution's licensing cost varies based on capacity and performance requirements."
"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."
"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."
"Pricing for this solution is reasonable."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"Our licensing is renewed annually."
"We used a reseller for the purchase."
"The price of this solution could be made more affordable."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"The price is a little high."
"I feel that the price could always be lowered."
"Our customers have seen a reduction in TCO."
