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 guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."
"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 solution's flexibility for supporting various data workloads while keeping them protected is great."
"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."
"The solution is stable."
"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 most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"We've found the product to be quite flexible."
"I am impressed with the tool's performance and bandwidth."
"The stability is excellent and we've found the product's performance to be very good."
 

Cons

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."
"The deployment of Dell PowerScale (Isilon) is not really complex but depends on the hardware deployment."
"Data storage performance needs to be improved."
"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."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"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."
"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."
"The solution is expensive. It's quite expensive for the amount of storage we have."
"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

"Pricing for this solution is reasonable."
"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."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"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."
"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 company finds the pricing high, but it decreases over time."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"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's price is reasonable."
