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.
ChukwuemekaOnyemelukwe - PeerSpot reviewer
An entry-level, flash-based storage system designed for enterprise-class applications
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 reliability and stability of Dell PowerScale (Isilon) is good, with no downtime."
"On a scale of one to ten, with one being worst and ten being best, I would rate Dell PowerScale (Isilon) a ten."
"The product's scalability feature is super easy to use."
"The most valuable feature is its single space of storage."
"The most valuable feature of Dell PowerScale is its scalability."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"The solution's most valuable features are scalability and flexibility."
"Dell PowerScale includes a wealth of features that are important from a security and recovery perspective."
"It has many options for scalability, and it is stable."
"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 ."
 

Cons

"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 would make Dell PowerScale (Isilon) better by improving SmartSync in the graphical user interface. Currently, everything has to be done through the command line, and I prefer having a graphical interface."
"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."
"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."
"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."
"The UID mapping and how to configure mapping-related things is a struggle."
"They could improve implementation, as we had to rack and stack it ourselves."
"The legacy file system for Epsilon didn't scale into the cloud and didn't have a separate OS. It would be key if this was made possible."
"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

"The platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."
"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."
"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."
"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 pricing is excellent."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"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."
"It is a really expensive solution."
"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."
"It is cheaper than other solutions."
