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.

Quotes from Members

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

Pros

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"We would highly recommend PowerScale; we've been very happy with our overall experience."
"Features like ransomware protection, file lock retention, and third-party integrations (e.g., Superna for ransomware protection) are significant benefits."
"Ability to scale the number of nodes without having to build additional clusters."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"I can certainly recommend PowerScale for mission-critical workloads, it is a powerful but simple platform with little administration overhead."
"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."
"Dell PowerScale (Isilon) has powerful security, which makes it a very reliable storage solution for our content, and also the support and observability of our system; the call home feature is fantastic because when it presents an issue, Dell automatically opens a ticket regarding any warnings or alerts, allowing us to have a complete view of our system's health."
"The stability is excellent and we've found the product's performance to be very good."
"I am impressed with the tool's performance and bandwidth."
"We've found the product to be quite flexible."
 

Cons

"The solution can be a bit complex for those not well versed in the technology."
"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."
"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."
"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."
"We see room for improvement in Dell PowerScale (Isilon) because we need personnel to effectively utilize all our infrastructure; it's not easy to find skilled people to work on AI and data analysis."
"The solution is expensive. It's quite expensive for the amount of storage we have."
"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."
"Backward compatibility is something Dell PowerScale (Isilon) could work on."
"The solution is quite expensive."
"The solution is quite expensive."
"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."
 

Pricing and Cost Advice

"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 pricing is excellent."
"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."
"It is a really expensive solution."
"The price of the solution is high."
"We use the TNA approach which is a great opportunity for us to better manage the licenses based on how much consumption is available for the different customers so we can use that approach and scalability."
"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 solution's price is reasonable."
