Has supported future scalability with seamless deployment
In terms of potential room for improvement regarding Dell PowerEdge M, I would want to see something such as dense nodes and additional storage, as well as multiple network connectivity on the blades. The functions that I would want to see from Dell are not limited to just what I mentioned, but currently, I feel no additional features are needed. I suggest adding an additional network card within the blades, specifically for connectivity.

Quotes from Members

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

Pros

"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."
"Overall, Dell PowerEdge MX- Series are solid products."
"The initial setup is easy."
"The iDRAC feature is most useful for server management in Dell, comparable to HP iLO."
"The installation is easy."
"PowerEdge M allows me to manage all servers and blades from one admin console."
"The tool's most valuable features are high availability and scalability. Its integration is easy."
"The server is more common for the mass market and although it is nothing special, what stands out is the good after-sales service provided."
"One of the most valuable features of this solution is its ease of use."
"It comes at a good price. We didn't face any problems with this product."
"We use the solution as a compute model to run the compute load on servers."
"The most valuable feature of the Lenovo Flex System is the storage system."
"The Lenovo Flex System is very stable."
"The initial setup is straightforward."
"Flex System's best features are its performance and stability."
"The functionality is reliable and requires minimal support."
 

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."
"Can be improved by being proactive in making changes that could improve the solution."
"The caching is a bit weak, making the hardware non-responsive, especially on hypervisor layers like ESXi or Hyper-V."
"The set up is complex"
"There is room for improvement in scalability."
"Dell PowerEdge M lacks GPU nodes and doesn't have a direct solution for GPUs."
"There is no specific feedback on improvements directly from our usage."
"We have had some issues with the vendor's support that we have received. When you open up a support case with Dell they send a partner to assist you and in our experience, they are lacking knowledge about the solution. There are times when you need professional support from the vendor that knows the solution well."
"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 solution could improve by providing more integration with other platforms."
"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."
"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."
"I had some difficulties with the initial setup."
"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."
 

Pricing and Cost Advice

"The product is neither expensive nor cheap. It is manageable for medium enterprises as well."
"The pricing of PowerEdge Next is higher than it was before."
"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 solution's pricing is slightly higher."
"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."
"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."
"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 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."
"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."
"We are just paying the operational cost, which is not much."
