To meet enterprise storage requirements, ThinkSystem All-Flash DM Series systems provide high performance, superior flexibility, and best-in-class data management. DM Series runs on ONTAP data management software, which gives customers unified storage across block-and-file workloads. It accelerates your business while improving the efficiency, flexibility, and reliability of your IT operations.
Lenovo ThinkSystem DM Series was previously known as ThinkSystem DM Series.
Our primary use case for Lenovo ThinkSystem DM Series is file storage and VMware. It serves as the backend infrastructure storage for VMware and for SMB sharing.
It has been a perfect fit for the workload that our customer is doing.
The valuable features include all the ONTAP features such as snapshotting and mirroring. These are very useful.
Lenovo could have a wider variety of storage solutions in the NAS space. Currently, as far as I know, there are only two or three different filers, and they don't extend to high-end filers like those in the NetApp environment.
I have been using it for about fifteen to twenty years.
I have not experienced any problems with stability so far.
There are limitations in terms of the capacity you can add to the filer, but it's quite a high level. The bigger limitation is the amount of client-side connections, which is limited by the number of PCI slots available for networking expansion.
Support from Lenovo has been very good overall. We haven't required technical support for storage products yet, but past experience from servers has been positive.
Positive
The initial setup was really easy. We had two engineers from Lenovo and myself involved in the process.
We had specialist engineers from Lenovo perform the implementation.
My experience with pricing and licensing is limited. However, Lenovo's price point is fairly competitive with NetApp.
We pretty much only considered Lenovo.
I would rate it a ten out of ten.
