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.

Quotes from Members

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

Pros

"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."
"The product's scalability feature is super easy to use."
"For maximizing storage utilization, PowerScale is great. When you write the data to it, it spreads it out to all the nodes, so you get all the performance from the entire pool."
"Its most valuable feature is the DR capabilities replication."
"Dell has the AI to protect the EMA."
"PowerScale allows us to manage storage without managing RAID groups or migrating volumes between controllers. It has really simplified things. We're not having to worry about the underlying infrastructure. That takes care of itself. We just worry about the data. It's really easy for deploying and managing storage at the petabyte scale."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"Based on the flexibility of the system itself, it was easy for us to manage the growth by buying individual nodes as needed."
"We've found the product to be quite flexible."
"I am impressed with the tool's performance and bandwidth."
 

Cons

"They should add some new services that should be for on-premises, and more analytics should be there for the data, allowing for a deep dive from that analytics, which is currently missing."
"Data storage performance needs to be improved."
"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."
"They could improve implementation, as we had to rack and stack it ourselves."
"Isilon has limitations on the number of files that can be generated."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."
"The solution's rate structure or rate redundancy needs to be improved."
"We have received complaints from customers that the tool is not easy to use. The tool's local technical service is slow. The solution is good for Linux customers and not for customers with other operating systems like Windows. The solution should provide storage without client software integration."
"The solution is quite expensive."
 

Pricing and Cost Advice

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"Dell PowerScale (Isilon) is an expensive solution."
"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."
"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."
"The solution's price is reasonable."
