What is our primary use case?
My main use case for Dell PowerEdge R-Series is servers for ERP for some clients, and servers for virtualization for some other clients. Those are the most used applications.
A specific example of how Dell PowerEdge R-Series was used in a virtualization or ERP project for a client includes the TOTVS system running locally for two clients on the R670xs, and for virtualization projects, most of my clients use the servers as file servers in virtualization with two or three virtual machines as the standard for the companies' environments.
I chose Dell PowerEdge R-Series because I know it is an extremely reliable machine. I usually purchase it with a 7-year warranty to give the client greater peace of mind. The machine usually lasts longer. I have some Dell PowerEdge R-Series units that have already been in use for 14 years and are still performing extremely well. Of course, with the limitations that come with age regarding processor architecture, memory, and disk, they continue to handle smaller functions in the environment. It's a long-term investment the client makes and it's equipment that will serve the environment for many years in a very efficient way.
In the functions where I use it, it serves extremely well, but in terms of AI, I cannot provide an answer because I haven't used it in that scenario.
Dell PowerEdge R-Series is deployed in my organization on-premises locally. It is a private cloud because all members of my clients' teams access it via VPN or some other secure access method. It can function as a local cloud, but most are on-premises with few units in colocation.
Today I don't have any AI application because my clients are smaller companies that don't have this type of application locally.
How has it helped my organization?
Dell PowerEdge R-Series has had a positive impact on my organization by providing better productivity and lower cost for my clients. There are applications where, if I consider the cost of that application being hosted in the cloud, in one year I pay for the server and from there on I incur fewer operating costs. This situation greatly facilitates the manager's investment decision because they make an investment in hardware that will serve them for 7 or 8 years, and with the cost they would have hosting this in the cloud, they would have a much higher amount to pay over time. Dell PowerEdge R-Series helps greatly in this characteristic. Since I also use 1U or 2U models, they offer very good rack density. I can sometimes have four, five, or six servers in a rack, offering very large processing capacity for the entire environment while keeping the infrastructure quite lean.
The use of Dell PowerEdge R-Series servers has greatly impacted my ability to offer better performance and better application performance in the environment, as well as management. As I've mentioned several times, iDRAC makes it much easier to manage the company's infrastructure area. I have alerts when an event occurs, and I have the convenience of doing firmware updates via iDRAC. Equipment management using iDRAC is quite integrated and greatly facilitates governance of these devices.
Regarding sustainability, all Dell equipment is produced with Dell already using recyclable materials in the manufacturing process, producing the product in a more environmentally friendly way. The product already comes from the factory with much better metrics than before. Considering the lower energy consumption that has already been mentioned compared to previous generations, that is, higher performance per watt consumed, they help process more data with less energy consumed, which greatly helps the company's sustainability profile. The product offers recyclability options and its longevity is quite high, at least 7 to 10 years.
What is most valuable?
The best features that Dell PowerEdge R-Series offers in my experience include redundancy for the power supply, which works extremely well, and Dell support. The storage options are also very extensive and good, especially the newer versions with NVMe and SAS options. I've been using NVMe and SAS more in these solutions for better performance, including mixing disk technologies and SSD units of different technologies. I can have two PERCs in the same machine to work with different disk systems. I can have a hard drive on one controller and SSDs on another controller without causing any problems. The ease of server maintenance is very high. I often provide server support and maintenance myself, adding memory and changing processors. It is quite simple. The options Dell offers are very good. iDRAC is also excellent. Management through iDRAC makes the IT technician's life much easier.
Regarding the AI features of Dell PowerEdge R-Series, if it's for AI applications, I have to select a version that supports the specific NVIDIA controllers for AI. Within the equipment's governance aspects, with the options it offers for me to manage the machine remotely via iDRAC and the Lifecycle Controller, it offers very interesting features for hardware and lifecycle management of the equipment, which really add to the proposal of having a machine like this used for AI, provided it is sized according to the required application or the application's needs.
In terms of power consumption, Dell PowerEdge R-Series servers have very good quality power supplies and energy consumption that I consider quite low compared to older products. When I remember servers around 2011 and 2012 that consumed a lot of energy, today in terms of performance per watt, they have exceptional capacity. With each year and each generation that comes out, there are more power-saving and integration features to reduce energy consumption. This is also helped by the fact that NVMe storage consumes less. The new memory standards usually also have lower power consumption than previous generations, which helps in the product's overall energy consumption in relation to the performance offered. Performance per watt in each generation rises considerably, and energy consumption remains practically the same, while processing capacity sometimes increases exponentially.
What needs improvement?
In terms of improving Dell PowerEdge R-Series, to be honest, the product has so many options that I find it very difficult to improve it in terms of product itself. Of course, there will always be some technological evolution and new components, but what the product offers in each generation, and I've already followed five or six generations of Dell PowerEdge from generation 11 up to generation 17, it has always kept pace with technological innovation. In terms of storage, it's always extremely in line with what the market is offering. In terms of memory, each new generation always follows the newest RAM trends. Processors also have both AMD and Intel options. I believe the product already has very high maturity. The availability of redundant power supplies and the availability of off-band management via iDRAC are excellent. The product is already extremely solid and reliable. The most I could perhaps say is that sometimes in some operations, I find iDRAC a bit slow, but that's a characteristic of off-band management because performance comes from a separate card that has its own processor and its own memory, so sometimes it's not as fast as I'd expect from the machine itself. Overall, there really isn't much to say because the product is extremely robust and efficient.
For how long have I used the solution?
I have been using Dell PowerEdge R-Series for 18 years.
What do I think about the stability of the solution?
Dell PowerEdge R-Series is extremely stable. I have servers that remain without rebooting for more than a year, occasionally rebooting only for some critical update, but the machine is never turned off. They run 24/7. I have machines that have been running 24/7 for 10 years, and the only times they needed to be restarted were for some critical update to avoid invasion risks or some problem of that sort. Apart from those reboots for Windows updates or Dell firmware updates, restarts don't occur. The machine remains continuously in operation.
What do I think about the scalability of the solution?
The scalability of Dell PowerEdge R-Series depends a lot on the choice at the time of purchase. If the client opts for a 2U model, for example, and later needs to expand storage a lot, there may be limitations. That's why product pre-sales is very important. The scalability options are excellent in memory, storage, and processor upgrades. I really have nothing to complain about. The machine has plenty of expansion capacity.
How are customer service and support?
Customer support for Dell PowerEdge R-Series is exceptional. Every time I needed Dell support—and I usually buy the equipment with at least 7 years of warranty and renew it after that period—service was very fast, and part replacement was done immediately. Most contracts are 4-hour response. I have never had any problem with Dell's service. On the contrary, Dell's service is outstanding in hardware support with the correct warranty. It's important at the time of purchase to also choose a ProSupport or ProSupport Plus warranty so that I have immediate service and avoid having equipment sitting idle. If I choose a basic warranty that covers weekdays 8x5, obviously if there is a problem on the weekend, at the end of the day, or at night, I will be without service. It's important to choose an appropriate warranty, but Dell's service is fast and efficient.
I rate customer support a 10.
Which solution did I use previously and why did I switch?
Previously, I used assembled servers. I built the machines myself, but that caused a lot of problems. The machines didn't have longevity because after 2 or 3 years I already had to replace the equipment. When I started using Dell PowerEdge R-Series servers, that changed. The machine practically only leaves when it really can no longer perform the tasks. I have Dell PowerEdge R-Series servers with more than 12 years in clients, while the assembled machines I used previously rarely reached 5 years.
What was our ROI?
Cost savings for clients translates greatly with Dell PowerEdge R-Series. For example, for one of my clients, the proposal for their ERP, TOTVS, to be in the cloud was R$ 8,000 per month. I paid R$ 86,000 for the server. In one year, I pay for this server and still have money left. In terms of performance, since this particular company has its team working more on the local environment than outside the company via VPN, the performance delivered to users is also higher. The ease I have in maintaining the environment with this equipment locally is also very great because I have an internal team, so I don't have to worry about whether they are managing backups in the cloud, and I have a very large saving in terms of investment in cloud services. If I were to consider the cloud's cost over 5 years, I would have bought five servers for this same role with the amount I would be paying for cloud hosting. This greatly reduces the cost for the client.
The use of Dell PowerEdge R-Series servers has helped reduce the total cost of ownership, the so-called TCO. It has helped greatly in the sense that the product's acquisition price is competitive and, considering the cost of workloads that I would have in the cloud—the same equivalent that I am paying for what is used locally on Dell PowerEdge in terms of cloud services—in at most 24 months the server is paid off and starts generating operational returns for the company. These machines easily reach 10 years of useful life. Even if it needs to be replaced for no longer having appropriate performance for the specific task it was originally purchased for, it can be moved to a secondary task and it continues to be a useful machine in the environment, where it can continue generating savings for the company because the hardware is already acquired and depreciated in the environment. The cost aspect is quite clear when I compare it with some workloads that, if placed in the cloud, would cost the price of three or four of these servers over five years.
In the case of the Dell PowerEdge R-Series servers I use for ERP, they have already reduced task processing time, which increases productivity. They have a reduction in TCO due to paying for themselves relative to cloud hosting. In terms of staff, the company's organizational structure was not affected in that sense, but the productivity of existing staff increased, which avoided the need to hire new staff.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, configuration costs, and licensing shows that there's been a very big change over the past year. There was an explosion in the prices of memory, storage, and server components in general, precisely due to the growth of AI data centers. This changed prices in a very negative way. Previously, I could build a high-performance server for a client for around R$ 80,000. Today that same server doesn't cost less than R$ 200,000. This is a situation that came to the market unexpectedly and has made things quite difficult. Right now, prices are very high, both for licenses and hardware. From clients, I've noticed a great difficulty for them to understand the change in price and the increase of more than 100% in many cases, especially in servers, and then make an investment. This makes things quite difficult.
Which other solutions did I evaluate?
Before choosing Dell PowerEdge R-Series, I evaluated HP and IBM. But Dell offered a better package. This was already back in 2011 and 2012. Today Dell has no competition in terms of server solutions. I practically can't even compare other brands' solutions with Dell's.
What other advice do I have?
I rate Dell PowerEdge R-Series a 10.
I give that number because the product has excellent configuration capability even before purchase. It very much depends on the technician choosing the appropriate components for the application the product will have in the environment. It has a very broad selection of processors, memory capacity, storage units, storage controllers, the option of management with iDRAC or without management, and an extremely wide range of network interfaces from 1-gig up to 100-gig interfaces. The product is extremely flexible already in its configuration phase and, when well specified, it will certainly deliver a sensational return on investment.
My role in the use or management of Dell PowerEdge R-Series is that I handle management and configuration. In pre-sales, I configure the hardware according to the environment where it will be used and the application that will run on this Dell PowerEdge R-Series. I determine the hardware specification beforehand, such as the amount of memory, how many processors, how many cores, which architecture, Intel or AMD, whether high-speed NVMe storage is needed, and whether I need HDDs for data storage in larger volumes, such as 12 or 20 TB. I perform the assessment before acquisition to determine the equipment, what type of network interface it needs, and what type of iDRAC. After that, I complete installation and configuration of the hardware to receive the applications and after that, maintenance of the machine lifecycle, including updates, firmware updates, and possibly hardware upgrades if necessary, specifying what needs to be updated. I may need to double the memory or add more storage space. I also perform this assessment and analysis, recommend the components, and add these resources to the server.
I would advise others who are thinking of using Dell PowerEdge R-Series to seek either Dell pre-sales or a professional with extensive experience in Dell servers so that the configuration is optimized before purchase for the application that will run on this server. It's very important to make the right choices before purchase to avoid, after the equipment has already been acquired, being unable to make upgrades, improvements, or component changes to deliver better performance or more storage space. It is essential before purchase to perform a very detailed analysis with the help of a Dell technician. Dell offers this pre-sales service to assist the client in purchasing the right equipment for their scenario.
