Has supported seamless integration and offers fast implementation
This needs to be checked for the most valuable features in Dell PowerFlex for data management. It is more stable, more powerful, and has more integration features. The scalability is very good and is one of the key features of Dell PowerFlex. Its flexibility and scalability are the main reasons we can use Dell PowerFlex.

Useful for virtualized environment, node management, configuration deployment, and system management with artificial intelligence
I've worked with Dell and had the privilege of working with many OEMs. I started my career as a system engineer, working with HPE as a partner, and then moved to other OEMs like IBM and Lenovo. Currently, I work with a small team. I don't believe any solution is bad. It's just that you might not have identified what the solution is addressing. It's about choosing the right solution for your needs. In terms of hardware or infrastructure, it's an Intel platform. What differentiates everyone is the additional value they can provide. Dell has many values that meet customer needs. I look at the customer's objectives and requirements as an IT professional to find the best solution. I haven't seen any drawbacks regarding the infrastructure deliverables or the value built into the tool. However, Dell as an organization could improve its channel management. For example, we've been trying to resolve an issue with our portal for two weeks. I'd like to see more simplification regarding integration, deployment, and connectivity for future releases. In deployment, I'd like to see simplification in creating VNets and positioning VMware across nodes. I want a template that simplifies the creation of VNets and VMware positioning. I'd push for more simplification and an intuitive graphical GUI that simplifies things with just a click.

Quotes from Members

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

Pros

"PowerFlex offers us more IOPS, improving the application performance. It also helps us reduce our storage and eliminate redundancy. The primary thing is that we work 24/7, so we shouldn't have operational issues."
"The most valuable feature of this solution is integration."
"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."
"Our primary use case of this solution is for storage nodes and compute nodes and I like that it is all in one box."
"The support is highly responsive."
"The solution has the benefits of any hyper-converged infrastructure but also has good hardware integration."
"The solution is very scalable."
"The program is stable."
"We completely replaced our old data center using this solution."
"Its performance is very good."
"Everything is delivered to me in a single box, which simplifies management."
"The monitoring and management parts are the most valuable. Monitoring is specifically valuable because you have one console to monitor everything. This console is called Vision."
"In comparison to traditional file load systems, Dell VxBlock System can be deployed quickly and results in monthly cost savings."
"Its performance is very good."
"Good flexibility and speed."
"Integration with VMware and VMotion definitely brings a lot of value."
 

Cons

"The storage capability must be improved."
"Including instrumentation would be a helpful improvement."
"The solution must be more flexible."
"We are still hoping for better ways to incorporate AI. We have to extend third-party access to PowerFlex by calling the API. It would be easier if the product had built-in AI integration. If PowerFlex can contribute more to AI, it would be more useful."
"The biggest issue with the solution is that it doesn't support Hyper V. It's a big problem."
"The tool needs to improve its storage. It should also make migration to the cloud easier."
"The level of support needs improvement as the front-line support staff lack knowledge when we raise cases."
"The solution’s automation and pricing could be improved."
"The hardware lifecycle is not documented very well."
"There is a need for single console management."
"Lacks flexibility with third-party applications."
"It is a good product, but for us, it is like a black box. We are not really sure about its internal components, and how to do the terminal upgrade, and how to make sure about the security of the device."
"We are finding it a bit challenging in terms of the management of a specific VxBlock component. Currently, we have different units as a part of the block storage. We have one for Cisco equipment and one for Dell. When we have an issue in the infrastructure, Dell EMC VxBlock System should automatically detect it and send a notification to VC support, but, unfortunately, it is doing that only for one unit. It is not working for Cisco components. We have informed them about this area of improvement, and they are working on this. The way different parts are integrated should be improved. We should have one console to log in to see all the infrastructure in terms of each machine and hardware."
"The solution could use a clearer description of working methods to tell people more about its use cases."
"I'd like to see hardware improvement and the ability to support different kinds of mixed applications - a mixed workload support."
"The only thing that I can say is when you procure the VxBlock, obviously you have to complete detailed questionnaires about your architecture including the configuration, et cetera. If you make a mistake on the implementation, then you need to rebuild the entire VxBlock. That is just a point of consideration rather than a flaw. You need to be absolutely sure and validate the upfront configuration information that you provide because your VxBlock comes delivered and built, according to that exact information."
 

Pricing and Cost Advice

"The solution's pricing could be much cheaper and affordable."
"The solution is expensive and I give the cost a two out of ten."
"The price of the solution is fair, it is priced in the average range amongst competitors."
"We have a good contact in Dell and he prepared all the information and provided everything to us."
"The pricing for this solution is good."
"The cost of this solution is fair."
"I rate the solution's pricing an eight out of ten."
"The solution's price is medium."
"Its price is high. That's why people are now moving to hyper-converge."
"We purchased this solution with a ten-year manufacturer warranty, and we have a three-year warranty with our local partner."
"Compared to other solutions, Dell VxBlock System is more expensive."
