Supports flexible hosting needs through seamless upgradability and strong monitoring capabilities
The most valuable features of Dell PowerEdge R-Series for me are the feature richness and the upgradability. I really love the way that it is so dynamically applicable for every situation, and they manage to have an all-in-one solution for every single situation. Dell PowerEdge has supported the growth and operational success of my company through its great compute power and price-to-performance ratio. Every time Dell is at the top of its game for us, and there is just no other brand for us that is able to reach that kind of price-to-performance ratio. Dell PowerEdge R-Series has features that specifically cater to the needs of my small company, such as iDRAC. The iDRAC system is a complete feature set for managing servers and hardware technically and monitoring-wise. It really fits in our system and our ecosystem, and monitoring-wise, it is excellent. They have all these sensors available via different protocols and end points, which I love, and the ability to manage and control everything via the iDRAC interface is just a welcome bonus. In our use case, Dell PowerEdge R-Series is very flexible. It is another computer which helps a lot because of the durability over time. They keep running, making scalability for getting more of those resources in our environment so easy.

Used to run the compute load on servers, but firmware and driver upgrades are a bit difficult

Quotes from Members

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

Pros

"In terms of handling the evolving needs of high-performance workloads, you get your money's worth."
"The product is well-rounded and has been effective in meeting our needs."
"Virtualization and distributed power management are good and valuable features."
"With this kind of product, we are solving a lot of problems, or issues that we had before with regards to performance."
"It is very easy and seamless to use the Dell OpenManage console for the lifecycle management of PowerEdge Rack Servers, and it is one of the best solutions in the market today to manage the lifecycle of services."
"We have about 80 servers and have only lost maybe two power supplies. They just run forever."
"The biggest value of PowerEdge servers is that Dell is a brand name. I also appreciate the flexibility of the platform. I know how to configure PowerEdge servers and build a solution from scratch."
"The most valuable features of Dell PowerEdge Rack Servers are their worldwide support, which is very accessible along with receiving assistance from professionals and specialists, and the continuous innovations that make it an amazing product in this era."
"Flex System's best features are its performance and stability."
"It comes at a good price. We didn't face any problems with this product."
"The Lenovo Flex System is very stable."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"I have found the solution to be quite stable."
"We are using Lenovo Flex System for our internal platform where we store our operating systems, Windows, Linux, and VMware, and then virtualize our machines."
"The most valuable feature of the Lenovo Flex System is the storage system."
"One of the most valuable features of this solution is its ease of use."
 

Cons

"The pricing of Dell PowerEdge Rack Servers has been a little problematic. It was sticker shock with our most recent purchase compared to the previous one, and there's a gap in pricing at our current level because what we do isn't very compute-intensive, resulting in a mismatch where we fit into an in-between category without an exact solution available."
"The equipment is very good, but the price is a bit too high. In addition, their support for parts can be better."
"Since the start of COVID, there is a shortage of support resources and it is challenging to get queries resolved quickly."
"I would like to see more information about server health and the server's state, on the front. HP has a little screen that shows server utilization, how many disks there are inside, and the power consumption. HP also shows an alert if there is a malfunction of any device inside."
"Even though there is some downtime, they are durable."
"Its pricing could be better."
"It's not the perfect solution but it is reasonable."
"The product must improve its integration with VMware."
"Flex System's integration with the XClarity Management System could be improved."
"I had some difficulties with the initial setup."
"The user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"The solution could improve by providing more integration with other platforms."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"The user-interface needs improvement, because they have an application from which we have to manage the whole system and all the infrastructure. This application is not working at our premises, because of some problem with the hardware itself. So although we brought it with our systems, and we used it to manage all the systems: the storage, the switches, and everything, nevertheless we have to support every part alone and enter the interface in one-by-one."
"It does not have the same module flexibility that was present in IBM Blade. On the Blade System, I was able to choose between the Cisco module, or BMC module. Since the switch to Lenovo, I have not had the same choice of modules, only the BMC modules."
"The solution's firmware and driver upgrades are a bit difficult."
 

Pricing and Cost Advice

"We have a strong agreement in place with our parent company, that typically ensures favorable pricing terms for us, although occasionally we may need to negotiate with Dell representatives for further discounts to provide competitive pricing to our customers."
"The price is good for the quality of the Dell PowerEdge Rack Servers."
"The price of Dell EMC PowerEdge Rack Servers is reasonable compared to other solutions."
"The overall pricing and licensing are fair according to the market."
"PowerEdge is not a cheap product. It's a quality product, but there is always competition. If you want to buy a server, you need an operating system, and most of it is Microsoft. A bundled solution costs less than a separate operating system and hardware."
"The pricing is very good because there are a lot of types of PowerEdge Rack Servers. You have the R540, R640, and R740. The prices are very scalable through the specific server, e.g., small businesses can take the R640 while large businesses can take the R740 or R840. Thus, Dell technologies touch on every organization."
"The pricing is great; very competitive. That's the reason we bought hundreds of them."
"The solution is expensive."
"We are just paying the operational cost, which is not much."
"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"The 14 blade server allows significant room for upscaling before having to invest in another chassis. You would have to purchase another chassis much sooner in the case of an eight or nine blade server."
"The is an annual license cost to use the Lenovo Flex System. If the price was less expensive and flexible overall and for additional features, our customers would be happier."
"We have the whole maintenance for the 3 years, starting the deployment. We also have the VMware license for 3 years and I think we have another license to buy. There are no additional costs besides licensing."
