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.

With a perfect record for uptime, the solution ensures a return on investment

Since it is a legacy tool, there is a need to change it for flexibility. I think now it has improved because the security is very good. It is very secure for the performance of the machine critical application service, and it is very good. I don't know how to speak more on improvement needed because it's a good enough tool. However, depending on the application, it's limited. Not a lot of applications run on HPE NonStop. It is not flexible because I know that because of the compatibility of Java with HPE NonStop. When we are using Java, the performance is not good.

Quotes from Members

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

Pros

"The speed of delivery is something super valuable. Reliability and performance are also valuable."

"Dell PowerEdge Rack Servers scale really well with the growing needs of my company."

"The most valuable aspect of Dell PowerEdge Rack Servers is that they don't require support for card installation and offer extensive diagnostic software."

"I've never had any down time with this solution and it's very user friendly."

"I've been consistently impressed by the exceptional build quality of Dell PowerEdge Rack Servers."

"The PowerEdge systems management frameworks have enabled us to progress towards full automation when it comes to managing PowerEdge."

"The lifecycle has been expanded because it is useful to use the older hardware that we have decommissioned for new use cases; they do not go immediately into e-waste."

"I like the reliability and ease of swapping out failed equipment. It is very easy to replace power supplies and drives."

More Dell PowerEdge R-Series pros

"It is a nearly perfect product, although it also has some restrictions and short comings."

"We don't have any issues with the stability of HPE NonStop."

"Technical support is A++. If there is a problem, HPE will fix it."

"If you are contemplating a fault-tolerant, high uptime transaction processing machine with above normal transactions volumes - to act as a transaction server with infrequent changes to code - and you simply must have bulletproof performance - this might be the ticket."

"The stability of HPE NonStop is good."

"They've been very reliable since we started using them in 1978, but we're going to replace them in a few years."

"Because we're able to get immediate support, this prevents downtime and directly impacts cost savings."

"The HPE NonStop solution is rated with the highest level of availability in the industry."

More HPE NonStop pros

Cons

"Dell PowerEdge R-Series could improve a little bit in resource management."

"The only challenge we have with the product is keeping it in line with VMware, knowing that VMware has now gone with a different provider."

"Dell needs to focus more on SMBs, helping us get the most out of our products. For example, at events, there should be very specific SMB sessions where there are Dell technicians, engineers, and Dell executives meeting with us and finding out what we need. Dell is big on promoting the fact that they're part of our team and that they want to be our partners, and I would like to see them actually partner with us. Do it less with the big Fortune 500 companies and do a little bit more with us SMBs."

"There are no items I want to improve on Dell PowerEdge R-Series; maybe just a discount."

"This is why, when we talk about the core system, we run another system, not Dell PowerEdge R-Series."

"The only growth complexity with Dell PowerEdge R-Series is that the cost of adding memory after the first purchase is always high."

"The aftermarket price for RAM modules and CPU cores is expensive. If I want to switch out a CPU or processor inside of my Dell PowerEdge to gain more cores, which increases my performance for VMware, the aftermarket price is so expensive that we typically take that box, retire an older Dell PowerEdge, and then buy a brand new one."

"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. Whenever we open any case for any customer, it takes more than five days. If we could handle it by ourselves, we could have the issue solved in one day. They should work on a way to fix these delays."

More Dell PowerEdge R-Series cons

"NonStop (formerly known as Tandem) in the Guardian OS could use another, friendlier macro language."

"It is not flexible...Not a lot of applications run on HPE NonStop."

"HPE NonStop could improve by having infrastructure management."

"Currently the NonStop platform doesn’t support virtualization of servers or CPU’s. Only storage."

"It would be helpful if they brought the price down."

"The hardware fails often, and I feel that HP really needs to pay more attention to this issue."

"The NonStop system is well priced, but the software that runs on it is quite pricey."

"If pushed, then the only thing I can think of would be utilities provided by the vendor."

More HPE NonStop cons

Pricing and Cost Advice

"The cost structure associated with Dell PowerEdge Rack Servers aligns closely with the prevailing norms established within the information technology hardware sector."

"It's abundantly clear that the specific licensing requirements will be dictated by the intricacies of the machinery we deploy."

"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."

"I have no issues with the pricing and licensing costs. They are fine."

"Regarding the pricing, it seems fair."

"The product is cheaper than HP servers, but the price could always be better."

"The licensing comes with a warranty."

"I am satisfied with the pricing of the Dell PowerEdge Rack Servers and would rate the cost as seven out of ten, with ten being the best."

More Dell PowerEdge R-Series pricing and cost advice

"The price of the solution is too high. If they lowered the price substantially it would open up more opportunities. It's considered a replacement for the old 9000 boxes of HP. If it had a lower price, we would be able to compete in the financial, and other sectors and other solutions such as Terraform. Having a high price makes other solutions more attractive."

"HPE NonStop is definitely on the higher end."

"On a scale of one to ten, where one is very cheap, and ten is very expensive, I rate the pricing an eight."
