My experience with the Lenovo ThinkSystem DM Series is very good. The pricing is okay, and it's one of the best systems. I rate the overall solution an eight out of ten. I advise using the tool; it is the best solution. Don't be misled by some people who say this is a Chinese company; this is incorrect. It is not a Chinese company but an international and big company. Lenovo currently offers many products for AI projects. I hope it becomes the number one distributor for AI next year.

The DM Series uses ONTAP software from NetApp, which is complex. You can't run this system if you don't have experience with ONTAP, then you can't install this system. We install the systems for the end customer. Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems.
