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.

Quotes from Members

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

Pros

"Dell PowerEdge Rack Servers powered by Intel are easy to use, are easy to manage with Dell's OpenManage Console, and have extended support for five years."
"Dell PowerEdge R-Series has improved my company by making it more efficient; less time is needed to roll out a server."
"I would recommend Dell PowerEdge Rack Servers if you want reliability, sustainability, and greater performance."
"What we like the most is the stability, because without shutdowns our VMs and servers are up and running fine."
"In comparison to what we had before, which was some older Dell equipment, the performance of the PowerEdge Rack Servers is stunning."
"The best features of the Dell PowerEdge Rack Servers are the service, the availability of the equipment, and the relational price quality."
"Dell PowerEdge Rack Servers have been stable and reliable over the last decade."
"The initial setup is pretty straightforward."
"The product is very user-friendly and has many resources at the enterprise level."
"The product is very user-friendly and has many resources at the enterprise level."
"The Lenovo Flex System is very stable."
"The Lenovo Flex System is very stable."
"I'd recommend Flex System to others as it's much better than any other product we've had and advise that they use XClarity for system management."
"It comes at a good price. We didn't face any problems with this product."
"Flex System's best features are its performance and stability."
"The functionality is reliable and requires minimal support."
 

Cons

"The versions that I work with, they used to max out on memory, on RAM, quickly, so I'd want to think in the newer versions, they actually allocate more processing power and more RAM to them."
"I would like to see a virtual view of the solution after creating and configuring it."
"The price is very high."
"Dell is expensive, which is a known fact. When comparing similar products, Dell often has higher prices."
"OpenManage Essentials could do with a visual birthday as it still requires the Silverlight plugin."
"The solution could improve by making the warranty policy better, which is a little bit complex because our local service partner Smart Technologies has long delays."
"Dell PowerEdge R-Series could be improved; some of the chassis could use a redesign, though I have older chassis, so I should go check their new models."
"The only aspect that could be improved is the price."
"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."
"The product could improve its integration capabilities."
"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."
"Forced restarts due to free upgrades is an issue that needs to be resolved. We can manage this as we have high availability and redundancy, but without that it could be a real problem."
"The user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"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."
"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 most valuable feature of the Lenovo Flex System is the storage system."
 

Pricing and Cost Advice

"The pricing is very competitive."
"We weren't paying very much, but it was at the end of the lifecycle. We are now using the VxRail hyper-converged infrastructure, and the pricing was very similar for the same amount of power but with easier automation."
"One of the clients has been offered a price of $18,000 instead of the regular price of around $25,000."
"Dell is somewhat more expensive than HPE."
"I personally think the pricing and licensing of Dell PowerEdge Rack Servers is actually fairly decent, though the way the business runs leads to sticker shock anytime we give them a quote."
"The pricing for this solution is reasonable. We pay a basic premium with a military premium on top of that."
"The cost structure associated with Dell PowerEdge Rack Servers aligns closely with the prevailing norms established within the information technology hardware sector."
"It's a bit of a shock when you have to find the money, but the pricing is very competitive, so I'm happy with that."
"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."
"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."
"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."
