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

"The solution is very scalable."

"The program is stable."

"The support is highly responsive."

"Dell PowerFlex is a one-stop-shop solution. Storage, compute, network, application monitoring, and support cases are all combined into one solution. It's very easy to administer compared to when you have a reference architecture where you need to design and build everything yourself. You would also then have to work with multiple vendors."

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

"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."

"We are planning to upgrade this system in three years, but in the meantime, we are happy with VxFlex."

"The most valuable feature of this solution is integration."

More Dell PowerFlex pros

"We completely replaced our old data center using this solution."

"It's a highly optimized piece of equipment that doesn't give us any problems."

"Good flexibility and speed."

"Everything is delivered to me in a single box, which simplifies management."

"Customers use the Dell VxBlock System for new applications or solutions. For example, I'm working on a new mixing solution for a whole country in Africa. When we talk about it, there are many locations, and we're looking for efficiency, utilization, and solutions that can expand the application database we're deploying. It's used a lot for server consolidation and to consolidate environments into new ones for easy management. It's also used in health environments where they need to create infrastructure for products or solutions they want to launch to the market quickly."

"Good default features."

"VxBlock has good performance, so that is an advantage."

"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."

More Dell VxBlock System pros

Cons

"The tool needs to improve its storage. It should also make migration to the cloud easier."

"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 level of support needs improvement as the front-line support staff lack knowledge when we raise cases."

"The solution is not as scalable as it should be."

"I think that stability is good for small and mid-level environments, but I don't think that it is suitable for high-end."

"For customers with a budget, it is a ten out of ten for the product, though it becomes challenging for those with mid or low budgets since it is very costly compared to other solutions such as PowerStore."

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

"They should provide continuous support for data migration."

More Dell PowerFlex cons

"The solution lacks some flexibility with third-party applications."

"There are components of VxBlock that are not managed or supported by Dell because some of the components are from Cisco. Thus, when there are problems with compute nodes, though Dell was managing the interaction, we had to rely on Cisco to solve the issue. When Cisco was not responding as quickly as Dell would for their components, it made it difficult for us because we needed to have the failed nodes back up and running. As such, the disparate ownership of components in the equipment is an issue."

"This solution does not support Hyper-V, and we would like the new version to be supported and certified to work with Hyper-V."

"The solution could use a clearer description of working methods to tell people more about its use cases."

"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."

"I'd like to see hardware improvement and the ability to support different kinds of mixed applications - a mixed workload support."

"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."

"Its price is high. That's why people are now moving to hyper-converge."

More Dell VxBlock System cons

Pricing and Cost Advice

"I rate the solution's pricing an eight out of ten."

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

"The pricing for this solution is good."

"The price of the solution is fair, it is priced in the average range amongst competitors."

"The cost of this solution is fair."

"The solution is expensive and I give the cost a two out of ten."

"The price could be improved."

"If one is cheap and ten is expensive, I rate the price as eight and a half. The tool is expensive."

More Dell PowerFlex pricing and cost advice

"We purchased this solution with a ten-year manufacturer warranty, and we have a three-year warranty with our local partner."

"Its price is high. That's why people are now moving to hyper-converge."

"Compared to other solutions, Dell VxBlock System is more expensive."
