Pros

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

"The resiliency and data protection are the most valuable features."

"The catalog of APIs for automation has been most valuable, although they are quite limited."

"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."

"Dell PowerFlex improves our latency which allowed us to reduce a lot of our Microsoft Enterprise SQL licenses."

"We've had no issues with scaling the solution."

"Saves us a lot of space in the data center."

"The solution is okay overall. It could be easier to learn."

"The biggest issue with the solution is that it doesn't support Hyper V. It's a big problem."

"It could be easier to learn."

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

"There should be more functionality available for routing."
