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.

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 most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."
"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."
"Dell PowerScale overall is easy to use."
"The flexibility and the user-friendly interface are the most valuable features."
"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."
"It's easy to manage. The web UI is very intuitive, and there's CLI also that you can use to manage it."
"The tool's most valuable features are high density and scalability."
"The most valuable feature for me is SyncIQ."
"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

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."
"Dell PowerScale's deployment is not easy."
"Dell's customer service needs improvement. Specifically, hardware failures under warranty should be addressed within the promised timeline."
"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."
"The solution isn't suitable for small environments or small customers."
"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."
"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."
"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."
"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."
"The call charges and the management cost should be more friendly. They can also include monitoring and management."
 

Pricing and Cost Advice

"It is a really expensive solution."
"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."
"Dell PowerScale (Isilon) is an expensive solution."
"The pricing is excellent."
"The pricing for this solution is reasonable."
"The price of Dell PowerScale (Isilon) is reasonable."
"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 is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."
"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."
