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 iDRAC feature is most useful for server management in Dell, comparable to HP iLO."
"The tool's most valuable features are high availability and scalability. Its integration is easy."
"I rate Dell PowerEdge a ten out of ten as it is a great tool with perfect support."
"It is easy to manage by an administrator and we can spend valuable time on other IT issues."
"The solution's most valuable feature is its interface."
"The solution is made with high-quality hardware."
"Dell is a reliable solution that does not usually require major support or experience part failures within two to three years."
"PowerEdge has high functionality, especially for automation on the firmware, which allows us to receive alerts for issues."
"I'd recommend Flex System to others as it's much better than any other product we've had and advise that they use XClarity for system management."
"The functionality is reliable and requires minimal support."
"We are using Lenovo Flex System for our internal platform where we store our operating systems, Windows, Linux, and VMware, and then virtualize our machines."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The initial setup is straightforward."
"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."
"The product is very user-friendly and has many resources at the enterprise level."
 

Cons

"The costing could be improved as it is somewhat expensive."
"The costing could be improved as it is somewhat expensive."
"One area for improvement is the connectivity, specifically the backplate and switch connections."
"Dell PowerEdge M needs to run AMD CPUs on it."
"The caching is a bit weak, making the hardware non-responsive, especially on hypervisor layers like ESXi or Hyper-V."
"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."
"Dell PowerEdge MX-Series is not a good solution for AI due to the lack of support for the expansion of GPUs; there is a solution, but it is not a useful one."
"PowerEdge M allows me to manage all servers and blades from one admin console."
"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."
"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 most valuable feature of the Lenovo Flex System is the storage system."
"The price of the Lenovo Flex System could improve."
"I had some difficulties with the initial setup."
"The product could improve its integration capabilities."
"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."
 

Pricing and Cost Advice

"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."
"If we would not have gone with the vendor we might have been charged unnecessarily for packages we did not need."
"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"It was budget friendly."
"The pricing of PowerEdge Next is higher than it was before."
"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."
"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."
"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."
"We are just paying the operational cost, which is not much."
"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."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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."
