Sr, Manager- Network Solution Architect at a energy/utilities company with 10,001+ employees

Comprehensive support and integration ensure smooth cloud infrastructure operations

I may not be the right person to comment on advanced improvements because we are just using basic functionalities. We are getting all the functionalities which we used to get in other OEM rack servers. Potential areas for improvement may include a more flexible pricing model, better technical support, or tutorials from the vendor for users.

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.

Stability has reduced hardware refresh needs and supports high-performance workloads

The best features Oracle SPARC Servers offer are that they are very stable and with high performance. Regarding the high performance aspect, I can say that they are great for databases and Java applications. Oracle SPARC Servers have positively impacted our organization because it's very good for our budget since we can use the system for so many years and don't have to buy new systems.

Quotes from Members

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

Pros

"On the Cisco side, there is a benefit in terms of server management. Cisco provides UCS Manager, which is a multi-tenant site manager. We can manage multiple sites while maintaining disaster recovery, a feature not available on other platforms."

"The most valuable features of Cisco UCS C-Series Rack Servers are agileness, ease of operation, and manageability."

"What I really like about the Cisco USC Server is its service profile."

"The C-series is the most valuable."

"The technical support from Cisco is fine."

"The support from Cisco UCS C-Series Rack has been very good."

"The solution has improved our organization by easily integrating with our VMware and storage solutions."

"What I really like about the Cisco USC Server is its service profile."

More Cisco UCS C-Series Rack Servers pros

"We do not have much workload right now. We are happy with whatever we have tested."

"The product serves as a good foundation because reliable, stable products are essential based on maintenance requirements and other factors, and this reliability is definitely one of the key pillars for choosing Dell."

"Virtualization is the biggest benefit for our organization, as we are able to virtualize a lot of applications and user desktops with the Dell EMC PowerEdge Rack Server."

"They help us work through things and they're also very competitive on pricing."

"I find the flexibility of the build-out in Dell PowerEdge Rack Servers very valuable because we can do different things based on the use case. This flexibility is highlighted by being able to reduce CPU count, RAM count, and the number of drives depending on the site's importance."

"We are able to do remote monitoring and installation of hardware and software, and that tends to be very popular with customers."

"The most valuable feature is OpenManage. We get a lot out of OpenManage because we have a sprawling infrastructure with around 100 data centers, and managing all of those separately is challenging."

"My company has seen a return on investment from using Dell PowerEdge Rack Servers, as the builds that the build team runs are going approximately 30% faster on the newer PowerEdge than what we were using previously."

More Dell PowerEdge R-Series pros

"The Oracle server is very powerful; they are more powerful and durable compared to Intel hardware, which has been a benefit to our organization."

"The processor is very helpful and the licensing is very flexible."

"I have found the LDAP facilities most valuable. In addition, I like the CPU."

"The processor is very helpful and the licensing is very flexible."

"The operating system is rock solid and the best I have ever used."

"Our customers are happy with many features in Oracle SPARC Servers, like the automatic ASR feature."

"The Oracle server is very powerful. They are more powerful and durable compared to Intel hardware. Which has been a benefit to our organization."

"Oracle SPARC Servers are definitely stable."

More Oracle SPARC Servers pros

Cons

"Cisco UCS C-Series Rack Servers could improve integration with third-party solutions."

"The warranty and support periods should be extended."

"Absolutely we had scalability issues. We tried several times to upgrade, scale up, expand our infrastructure, but Cisco insists to demand excessive amounts of money."

"The only thing I would change is to provide more proactive support."

"The solution can be improved by adjusting the cost."

"Some customers have complained about delivery time. So, the main weakness is the lead time."

"The initial setup could be easier."

More Cisco UCS C-Series Rack Servers cons

"We have experienced some challenges with iDRAC when upgrading firmware."

"A feature that would enhance Dell PowerEdge Rack Servers is the ability to get multiple servers up and running quickly versus having to do one at a time."

"The solution should give us an option to add on the new hardware features."

"There are a lot of data platforms around, but it would be helpful if we could perform some basic data operations on the server so we don't need an extra vendor. Azure is their Microsoft Cloud solution, and they collaborate with data companies like Databricks. We are also on the cloud and work with Databricks, but they could add some basic features so an enterprise doesn't need to go for extra Databricks to do their data things."

"We are working with national markets, and HP Enterprise is cheaper. Dell could have made an effort there."

"The solution could still use some more analytics."

"Newer systems are more sustainable in terms of energy consumption. I need to consider more power-saving and sustainable options."

More Dell PowerEdge R-Series cons

"Oracle SPARC Servers are expensive to manage, this is because after five years Oracle will increase the support charges for the hardware."

"The solution could improve by giving a clear roadmap about the future. I'm not seeing a lot of improvements on the OS side of the software. They need to work more on the operating system."

"Oracle SPARC Servers should be fine-tuned well enough to work with the other servers and software products in the market, as it is an area where Oracle SPARC Servers lack."

"Like IBM, Oracle SPARC Servers should be able to run other open operating systems like Linux."

"I would like to see a reduced price point."

"They have declared the end of life of the hardware."

"They need some sort of modeling because IBM has different types of models."

More Oracle SPARC Servers cons

Pricing and Cost Advice

"The prices of Cisco UCS C-Series Rack Servers are higher compared to the competition. When we try and sell against the competition, then it becomes quite difficult to sell"

"Best to buy all the blades configured for the same purposes of load balancing and failover or load shifting."

"This product is quite expensive and it would be better if it were cheaper."

"My company has an agreement with Cisco to get discounted rates. It is one of the reasons why we chose the product."

"The price of the Cisco UCS C-Series Rack could improve. It's a little more expensive in comparison with Dell or HPE solutions."

"The price of Cisco UCS C-Series Rack Servers is approximately 20 percent more than other solutions."

"Licensing fees are paid on a yearly basis, which is only $2,000 or $3,000."

"The solution is moderately priced."

More Cisco UCS C-Series Rack Servers pricing and cost advice

"The pricing is very competitive."

"Compared to other vendors, the prices are much lower."

"PowerEdge pricing is equivalent to that of all the others in the market."

"It is expensive. The price needs to be more competitive. Additional licenses are required to enable some of the features for scalability."

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

"You can't have computed performance without using more power. That said, when I consider the power consumption and performance of the MX740c, depending on how much memory you install on each blade, you get the best bang for your buck."

"I don't know about the product's licensing part. Price-wise, it is an okay product. I believe that the cheaper the better, but I think that the product's price is okay."

"The licensing is expensive and inflexible."

More Dell PowerEdge R-Series pricing and cost advice

"The hardware is expensive but it has very rich virtualization features that make it economical."

"The licensing is flexible."

"Oracle SPARC Servers are expensive to manage, this is because after five years Oracle will increase the support charges for the hardware. The licensing policy for Oracle is different for Intel and Sparc. It will cost you less if you use your Oracle hardware with Oracle SPARC Servers."

"My company makes yearly payments toward the licensing costs attached to the solution."

"The application running on it is very important to us and this makes the price worth it."
