Blade platform has supported clustered production workloads and delivers strong performance
In the industry, there are currently blade solutions from Dell, HP, Lenovo, and Cisco. Compared to those, all blade solutions are similar in design. In the chassis, there is a back panel where each blade has a card module that plugs into the blade chassis. The chassis contains a network switch as well as a SAN switch. The SAN switch and network switch combined to the blade module provide plug-and-play functionality. The throughput is also good. Dell PowerEdge MX- Series currently has two types of processors with speeds of 2.1 and 2.3 GHz, possibly 2.2 GHz as well. All applications in our environment run on these processors. However, I think the processor speed should be higher because the coming applications are all AI-based and require more powerful processing. As of now, there is no issue with the current processor clock speed for our running applications. They are all Gold processors. In our environment, we have designed a setup with Dell PowerEdge MX- Series chassis with two network switches in the back panel. The two network switches connect to the main upstream network switch with link aggregation protocol (LACP) bonding. Currently, 160 gig, 40, 40, 80, and 80 gig bandwidth is running. The throughput is 80 gig total. Each blade server has a 20 gig network connection and will get a maximum of 20 gig network bandwidth, while the total chassis will deliver a maximum of 80 gig bandwidth. However, it can go up to 160 gig because the upstream network switch supports QSFP+ modules that are 40 gig each, with two 40 gig connections totaling 80 gig. Dell PowerEdge MX- Series also includes a SAN switch. The SAN switch is in the back panel of the chassis and connects to our main central SAN switch, which is connected to central storage. It is easy to onboard our central storage to the blade server as required, and there is no issue with that. The benefits include the fact that Dell PowerEdge MX- Series blade servers have sixteen blade servers in a single chassis, which consumes minimal space in the rack and data center, as well as requiring minimal cabling. For cabling, there are only four network cables connected to the main upstream switch. When connected to the SAN switch, there are only four additional cables, totaling eight cables to the SAN switch. This results in no messy cables in the data center. Additionally, the performance is good enough based on our current applications running on the servers.

Quotes from Members

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

Pros

"One of the best aspects of PowerEdge is that it provides a consolidated hardware infrastructure, allowing multiple servers in a simple ten-rack unit."
"The solution is made with high-quality hardware."
"The iDRAC feature is most useful for server management in Dell, comparable to HP iLO."
"PowerEdge has high functionality, especially for automation on the firmware, which allows us to receive alerts for issues."
"The Integrated Lights-Out (iLO) support is notably better than that of other servers."
"The biggest advantage of PowerEdge is that it is cost-effective, and its performance and infrastructure are much better than other competitors like Lenovo and HP, with very good performance even when you are using it at one hundred percent load."
"I have compared Dell EMC to other solutions and have found it to be good. The SAN and LAN traffic, manageability, and upgradability are all good."
"The solution integrated well."
"The Lenovo Flex System is very stable."
"The product is very user-friendly and has many resources at the enterprise level."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The Lenovo Flex System is very stable."
"It comes at a good price. We didn't face any problems with this product."
"One of the most valuable features of this solution is its ease of use."
"The initial setup is straightforward."
 

Cons

"There is no specific feedback on improvements directly from our usage."
"The ever-increasing boot time due to ever-increasing POST checks with every new generation makes maintenance tasks somewhat of a headache."
"Dell support should be faster. Dell's technical support sometimes takes time, and there's a support gap issue."
"It requires time to transition to the new generation."
"I wanted to highlight that sometimes the patches from the firmware are not compatible with the hardware, which can crash the operating system and mess up the RAID configuration."
"PowerEdge M allows me to manage all servers and blades from one admin console."
"In terms of improvement, it should also offer a hyper-converged option."
"One area for improvement is the connectivity, specifically the backplate and switch connections."
"The most valuable feature of the Lenovo Flex System is the storage system."
"I had some difficulties with the initial setup."
"Flex System's integration with the XClarity Management System could be improved."
"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."
"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."
"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 solution could improve by providing more integration with other platforms."
"The product could improve its integration capabilities."
 

Pricing and Cost Advice

"The pricing of PowerEdge Next is higher than it was before."
"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"The cost varies significantly depending on the server's configuration and can range from $10,000 to $60,000 for the same server line family."
"It was budget friendly."
"The product is budget-friendly. The initial cost for each server was around 10,000 euros. It's a standard price, not too high or too low."
"If we would not have gone with the vendor we might have been charged unnecessarily for packages we did not need."
"Dell PowerEdge M price is comparable to other solutions but cheaper than IBM. However, the IBM solution is a higher grade solution whereas Dell PowerEdge M is a medium-level solution."
"The solution's pricing is slightly higher."
"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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."
"We are just paying the operational cost, which is not much."
