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

Pros

"I find all the features of this solution excellent, and the ability to move data to the public cloud is valuable."

"I find all the features of this solution excellent. The ability to move data to the public cloud is valuable."

"PowerFlex allows us to scale compute and storage resources independently, which is extremely valuable for optimizing costs and right-sizing infrastructure based on workload demands, particularly in environments with variable AI and database workloads."

"The most valuable feature is the overall integration and just seeing the three different layers which make up the machine software. Altogether, it's something that I would say is much better than any other solution that I have experienced before."

"It has reduced downtime. Before, on our previous solution, we used to have downtime on some of the servers because of the sort of convention. But currently I've not experienced any downtime on any of the servers, and there is no more resource congestion."

"The integration with AWS is a valuable feature."

"We're doing a lot of VMware for IT so this solution is really valuable from a VMH point of view. We're trying to assist our customers mainly with management, because that's what they want. The most important aspects are ease of management, as well as ease of configuration, allowing them to attach additional nodes and resources for the applications."

"The solution is very scalable."

"The tool's most valuable features are its price and flexibility. It has high performance."

"The support team responds quickly."

Cons

"The pricing and the partnerships with AWS and Azure can be improved."

"The installation is complex."

"The initial deployment was complicated and required a lot of data nodes, IPs, internal vLANs, data vLANs, and many other things."

"Exporting data from the dashboard is not very user-friendly. It's just designed in a way that it's going to cover let's say 90%, 80%, of the end-users needs. If you need more sophisticated reporting it's not easy to have."

"The solution needs to offer more documentation and educational materials."

"The support of containers needs to be improved. At present, it is limited to VMware. There needs to be direct communication with the hardware rather than through a hypervisor."

"We're also running Hyper-V virtual machines. But we recently discovered that migration of the Hyper-V virtual machines is a bit challenging."

"We've had some issues around the licensing."

"I think there might be some room for improvement when it comes to pricing, because although I know how to convert customers, at the end of day, it's quite expensive. Sometimes your feature architecture is still coming out much cheaper than hardware costs for your infrastructure."

Pricing and Cost Advice

"The solution's pricing could be much cheaper and affordable."

"We have a good contact in Dell and he prepared all the information and provided everything to us."

"The product is expensive."

"The price could be improved."
