I would not recommend Lenovo ThinkSystem DM Series to others. There are better storage systems available, such as NetApp and Dell Unity

I have used versions DM3000H, DM5100F, and DM7100F. I will recommend the solution to others. Overall, I rate the solution a nine out of ten.

I rate Lenovo DM Series eight out of 10. My advice is to try it. If you are a NetApp or Dell EMC customer, you have to try DM Series because I think DM Series is a scalable all-in-one system with unified block and file storage and cloud tiering. 

I recommend this solution to others. It is a very good solution and it is carrying the legacy of IBM.

I rate Lenovo ThinkSystem DM Series a nine out of ten.

I have experience with all-flash storage arrays. I've used IBM NVMe Series, Dell EMC Unity, HPE, and Juniper.

We're using the Lenovo ThinkSystem DM Series, particularly the DM7000 version.

The Lenovo ThinkSystem DM Series can be deployed on cloud and on-premises.

We're a Lenovo partner.

I'd rate the solution six out of ten.

With Lenovo, there are only two solutions: the DE or DM series. For common workloads, we tend to recommend the DE series as it's the best match for smaller companies. The DM series is more for those with many workloads that need very high performance. In use cases where the Workload needs performance, we advice our Customer to take the advantage of the Lenovo Best in Breed DM-Systems.

We typically advise customers to choose the DM series.

In Germany, we have many small firms and smaller environments. Most people will tell clients they absolutely need flash. However, we don't think that is always the case. It's similar with DM. You can't sell clients with small issues or small storage requirements something that offers flash all the time. It's expensive. You need to think about costs and be strategic to ensure you're meeting your client's needs responsibly.

We use the on-premises deployment model.

I would rate the solution six out of ten.

In summary, this is a good product and is one that I recommend.

I would rate this solution an eight out of ten.

I would rate this solution a ten out of ten.

It's important to know that the storage is entry level mode. In comparison with other similar solutions, I think this one is the most expensive. Clients don't understand why they should pay so much money for the DM Series. It's possible to get other solutions with similar configurations like SSV, SaaS, HPE, MS-DOS. These are cheaper solutions. 

I would rate this solution a nine out of 10.
