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.

A very high IOPS that gives more I/O transactions per second
Scalability used to be an issue so at that time it was rated an eight out of ten. We have become OPEX-based and rent storage from them. Physical storage is about 200% of our requirements but we only pay for what we use. This resolved all of our scalability issues. When we reach a certain threshold like 100%, OPEX calls us and asks if we want to add more storage. Our total capacity right now is 300 terabytes but we are only using around 200 terabytes. We bought the storage two years ago and our projections are on par. We don't need more capacity now but have plans to increase in another two years. With our OPEX storage, scalability is rated a nine out of ten.

Quotes from Members

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

Pros

"The solution's stability is good...The solution's scalability is good."
"Looking at the new models, they have greatly improved the cooling system, which is a significant advantage."
"I like the iDRAC feature. I have also seen long life from each part and haven't had to call support, as far as I remember. I use competitors like HPE and we need spare parts every year."
"Dell PowerEdge R-Series product is overall very stable, very mature, and support is excellent."
"You are provided with excellent instructions."
"In Dell PowerEdge R-Series, the most valuable feature is the management."
"Dell support is the best."
"The pricing of the solution is fair."
"The solution has high IOPS and the I/O is important because it gives us more transactions per second."
"The combination of Cisco's architecture and IBM's flash technology, where Cisco provides FI technology for one simple architecture and IBM's flash technology is fast, is valuable."
"Replication and DR implementation became faster."
 

Cons

"The vendor must provide cheaper versions of the tool for smaller use cases."
"We have experienced some challenges with iDRAC when upgrading firmware."
"The solution should give us an option to add on the new hardware features."
"The shipment times could be improved. Sometimes we have to wait four or five days before we get the actual servers. It could even be longer. Sometimes it is many days."
"The price is the only thing that can be improved."
"Access to specific card models can be limited, and sometimes we require smaller cards than those offered by Dell."
"I wish that Dell had a competitive product to the HPE MicroServer because if they did, I would buy them, not in their hundreds, but certainly in their tens, especially in my capacity as an MSP."
"The physical design could be improved as it is heavy and quite large when racked."
"Raw data mapping for storage should be a given option."
"The solution should improve deduplication to get a lot of savings."
 

Pricing and Cost Advice

"I don't see any issues with respect to licensing. It's power-efficient, so it's beneficial to the customers price-wise. There are no costs in addition to the standard licensing fee."
"The price of this solution is reasonable. It's very comparable to similar solutions."
"The pricing for this solution is reasonable. We pay a basic premium with a military premium on top of that."
"Dell is priced better than alternative solutions."
"Pricing appears to be comparatively favorable, particularly within the project's scope."
"The product's pricing is not good."
"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."
"We have not compared them with others. The price is okay, but they can always be a little bit cheaper."
"The solution is enterprise level so it is expensive."
