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.

Private cloud control has deepened my DevOps automation and strengthened security practices

For improvement, I feel the documentation available for setting up and creating infrastructure using Rackspace OpenStack could be enhanced, as I personally find the existing documents are not sufficient for new learners or beginners. We can also work on improving the user interface; the Horizon dashboard is functional, but compared to AWS, Azure, or Google Cloud, the UI feels somewhat dated. A more modern, intuitive interface with better navigation would enhance the overall user experience, especially for new users. Improving the documentation, including more real-world deployment examples, troubleshooting guides, and architecture best practices, would make onboarding much easier. Faster upgrades would also help; Rackspace OpenStack upgrades can sometimes be complex, so simplifying the upgrade process and minimizing downtime would assist organizations in maintaining their environments more easily. Additionally, improving monitoring capabilities would be beneficial, with advanced monitoring and analytics dashboards providing administrators deeper visibility into performance, capacity, and potential issues without relying heavily on third-party tools. Adding more managed services, similar to what public cloud providers offer, could reduce operational overhead while still allowing customers to retain the flexibility of a private cloud. Lastly, integrating AI could be valuable, with AI-driven recommendations for capacity planning, security monitoring, and automated troubleshooting improving platform management.

Quotes from Members

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

Pros

"Having switched to the VxBlock provided the business with almost no downtime, and we run an extremely stable, efficient operation at this point in time."

"In comparison to traditional file load systems, Dell VxBlock System can be deployed quickly and results in monthly cost savings."

"Good flexibility and speed."

"It's at least 99 percent problem-free because it's factory-built. So from an informational point of view, everyone trusts that VxBlock has been tested well at the factory and has been configured to their requirements."

"When they implemented VxBlock, they doubled the speed of their operations, as a process that used to take eight hours now only requires four hours, so they're getting a return in terms of performance."

"The stability is good, we haven't had any problems and we're happy with the product."

"Virtual machines for the infrastructure."

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

More Dell VxBlock System pros

"Rackspace OpenStack impacted my organization positively in that the drive helped me keep files in an organized folder, and obviously we needed email addresses to be able to communicate with each other and for outsiders to be able to email us."

"Rackspace OpenStack has positively impacted my organization by bringing us much closer to our customers based on the supportability this platform provides, and it has unique features which are very useful for our customers."

"Administrators are very comfortable with the functionality and services OpenStack offers."

"The most useful opinion about Rackspace OpenStack is that it is very flexible, first of all, and the most important feature is that it is feature-rich."

"OpenStack allowed for mass uploading of images to Akamai cloud services."

"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."

"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."

"There are many services that can be directly used which are not available in VMware."

More Rackspace OpenStack pros

Cons

"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."

"Does not support different kinds of mixed applications."

"For VxBlock, the consistency of disc quality could be improved."

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

"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."

"It's a good product but the price could be lowered. It's expensive."

"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."

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

More Dell VxBlock System cons

"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."

"As a beginner, I find some difficulties in understanding Rackspace OpenStack, as it can be complex without a foundational grasp of cloud and networking concepts."

"The pricing for Rackspace OpenStack is sometimes not competitive according to other market products, as sometimes the price is high for some components like Advanced Cluster Management (ACM) and Advanced Cluster Security, which are very costly add-ons, not the main license."

"OpenStack is difficult for the novice in terms of beginning to use cloud tools."

"The pricing of Rackspace is quite high in the Vietnam market."

"For improvement, I feel the documentation available for setting up and creating infrastructure using Rackspace OpenStack could be enhanced, as I personally find the existing documents are not sufficient for new learners or beginners."

"We are moving from Rackspace OpenStack to CloudStack due to the requirement of human resources and technicality. There are lots of moving parts in Rackspace OpenStack."

"In terms of what needs to be improved, I would say the support. Rackspace might have some good support but the open source OpenStack doesn't have support because there are too many versions coming and too many people are customizing it."

More Rackspace OpenStack cons

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."

"The pricing is low."

"I use it as an open-source tool."
