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.

It took significantly longer to set up the solution with Huawei compared to other options. But when creating servers for VMware virtualization in one data center, it was a relatively quick process. The Huawei's solution, even with the assistance of an engineer, took more than one month, possibly extending to two months. Chinese engineers were involved in the process, which contributed to the delays.

Quotes from Members

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

Pros

"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."
"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 overall is easy to use."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"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."
"It is stable and very user-friendly."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."
"The storage capacity is really one of the most valuable features. Also, the GUI is very friendly and the switches gives high performance. The technology used in storage is RAID which as helped us a lot to expand and store various items ."
"It has many options for scalability, and it is stable."
 

Cons

"I think Dell PowerScale (Isilon) can be improved, as the cost models are quite expensive for administration."
"It is a bit higher priced than some of the other systems."
"The solution’s interface and pricing could be improved."
"If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened."
"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."
"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."
"The price of the solution could be reduced."
"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."
"The call charges and the management cost should be more friendly. They can also include monitoring and management."
"The handling of data deletion and bulk servers setup could have been more straightforward and easier when dealing with data removal or setting up servers. I believe Huawei could enhance their solutions, especially managing storage, to provide a better experience for customers."
 

Pricing and Cost Advice

"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 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."
"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."
"The solution's licensing cost varies based on capacity and performance requirements."
"The price of Dell PowerScale (Isilon) is reasonable."
"Our company finds the pricing high, but it decreases over time."
"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."
"It is cheaper than other solutions."
"The installation is expensive as they often come as a comprehensive package. The design is more integrated, and everything is bundled together as part of the solution. This is what contributes to the higher cost of their solutions because when you purchase one element, it often comes with additional features and components, and you end up paying for the entire package."
