Modern infrastructure has reduced our rack footprint and simplifies large-scale virtualization
No product is perfect, and there are improvements that can be done on Dell PowerEdge MX- Series. The first improvement is the complex matrix for firmware updates and patching. Managing the cycle for a modular chassis means managing alignment across multiple layers: the chassis management module, compute nodes including I/O, BIOS, and iDRAC, switch network OS such as SmartFabric OS, and the hypervisor driver.Upgrading firmware can feel challenging when an OS10 switch patch is out of sync with an iDRAC version and a VMware ESXi driver release, as it can trigger network instability or failed compliance checks. A simple, single-click, whole-stack update engine that completely guarantees baseline stability across switch OS, server BIOS, and hypervisor drivers without manual dependency checking would be beneficial. The second area for improvement is the high upfront cost and initial setup complexity. The initial capital expenditure for an MX7000 chassis, redundant management nodes, and fabric switching engines is steep compared to buying a few standalone 2U servers or rack servers. Additionally, initial configuration, particularly setting up SmartFabric services and inter-chassis stacking, has a steep learning curve. A lower barrier to entry price for smaller cities and a simplified deployment wizard for IT generalists who do not specialize in enterprise network fabrics would be improvements. The third improvement is the limited native GPU density for modern AI workloads. While composable PCIe fabric exists, running intensive AI training locally inside the chassis is restricted. Sleds designed with specialized cooling, specifically tailored to support high-wattage enterprise GPUs natively with the standard sled footprint, would be beneficial. Power and thermal management per rack is another area that can be improved. A fully populated MX7000 series loaded with high-wattage CPUs, dual switches, and NVMe drives consumes a significant amount of power in a compact 7U space. Racking three or four chassis in a single rack can typically exceed standard power density limits or require specialized rack power distribution units and high-CFM cooling airflow.

Quotes from Members

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

Pros

"Dell PowerEdge MX- Series has impacted our organization in a very positive way, and there are many benefits to it."
"I prefer the central pane of glass management feature of Dell PowerEdge MX- Series the most."
"The tool's most valuable features are high availability and scalability. Its integration is easy."
"It's great for managing overall infrastructure."
"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 initial setup is straightforward."
"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."
"The solution integrated well."
"I have found the solution to be quite stable."
"Flex System's best features are its performance and stability."
"It's stable, it works well, and we have had no problem with it for a long time."
"One of the most valuable features of this solution is its ease of use."
"The initial setup is straightforward."
"The most valuable feature of the Lenovo Flex System is the storage system."
"We use the solution as a compute model to run the compute load on servers."
"The functionality is reliable and requires minimal support."
 

Cons

"I suggest adding an additional network card within the blades, specifically for connectivity."
"The caching is a bit weak, which can make the hardware non-responsive, especially on hypervisor layers like ESXi or Hyper-V."
"Dell PowerEdge M lacks GPU nodes and doesn't have a direct solution for GPUs."
"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."
"In HP, there are some series of servers which are called partition servers. These use virtualization built-in on the server hardware. I am not seeing this feature in Dell."
"The biggest challenge happens when you have compact boxes such as Dell PowerEdge MX- Series. Managing or maintaining the server ratio within a rack becomes jumbled up because per rack you get a limited power capacity."
"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."
"Technical support is not good."
"The user interface needs improvement because they have an application from which we have to manage the whole system and all of the infrastructure."
"Continuing the production of this product is necessary. It is currently out of support, and we are seeking support from other sources besides Lenovo."
"The price of the Lenovo Flex System could improve."
"I had some difficulties with the initial setup."
"The solution could improve by providing more integration with other platforms."
"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."
"Flex System's integration with the XClarity Management System could be improved."
 

Pricing and Cost Advice

"The solution's pricing is slightly higher."
"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."
"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"If we would not have gone with the vendor we might have been charged unnecessarily for packages we did not need."
"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."
"It was budget friendly."
"The pricing of PowerEdge Next is higher than it was before."
"There is a one-off payment to buy the equipment and the support is purchased annually."
"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 price is interesting. I am able to quote a client based on their needs and offer them either Lenovo or Dell."
"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."
"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."
"We are just paying the operational cost, which is not much."
