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

"The solution is made with high-quality hardware."
"The solution offers remarkable flexibility, reliability, and extensive software support."
"The initial setup is straightforward."
"The Integrated Lights-Out (iLO) support is notably better than that of other servers."
"Dell PowerEdge MX- Series enhances my IT department's operational efficiency through several valuable features, including modularity that allows for easy scaling and good planning, and advanced networking capabilities with SmartFabric that make upgrades plug and play while it takes care of everything."
"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."
"PowerEdge has high functionality, especially for automation on the firmware, which allows us to receive alerts for issues."
"The initial setup is easy."
"The Lenovo Flex System is very stable."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The functionality is reliable and requires minimal support."
"The initial setup is straightforward."
"One of the most valuable features of this solution is its ease of use."
"Flex System's best features are its performance and stability."
"The stability and speed are always good. The processor is good and it's still working with our loads."
"It comes at a good price. We didn't face any problems with this product."
 

Cons

"Regarding firmware updates, the complexity of seeing the compatibility matrix with the operating system and all the firmware that we have to install in Dell PowerEdge MX- Series blade servers, the chassis, and switches inside is challenging."
"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."
"For the support of Dell PowerEdge MX- Series, I would rate it a seven; for EMC storage, Dell is not performing as well as EMC, but for servers, they are good, so I would say seven or eight."
"I suggest adding an additional network card within the blades, specifically for connectivity."
"One area for improvement is the connectivity, specifically the backplate and switch connections."
"Compared to other solutions, this blade server requires more stability."
"Dell PowerEdge M needs to run AMD CPUs on it."
"It requires time to transition to the new generation."
"The product could improve its integration capabilities."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The solution's firmware and driver upgrades are a bit difficult."
"Flex System's integration with the XClarity Management System could be improved."
"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."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"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."
"I had some difficulties with the initial setup."
 

Pricing and Cost Advice

"The solution's pricing is slightly higher."
"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 cost varies significantly depending on the server's configuration and can range from $10,000 to $60,000 for the same server line family."
"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."
"It was budget friendly."
"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"I know we get three years basic, and the on-site licensing model for business seems fine. I wouldn't pay for a support plus or anything."
"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."
"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."
"The price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
"We are just paying the operational cost, which is not much."
