Lenovo ThinkSystem DG5000
The ThinkSystem DG5000 was Lenovo's entry-to-midrange unified all-flash array powered by Quad-Level Cell (QLC) NVMe flash technology and Lenovo ONTAP, based on OEM NetApp AFF C-Series architecture. Engineered to replace traditional 10K/15K RPM hybrid hard drive arrays with flash economics, it delivered flash speed, ultra-low rack space consumption, and reduced power costs for capacity-oriented workloads including secondary tier virtualization, disaster recovery targets, big data repositories, and file consolidation. Inline deduplication, compression, and compaction maximized usable QLC efficiency. Used equipment buyers should inspect ONTAP software licensing bundles, verify remaining write endurance across the installed QLC NVMe SSDs, and ensure controller batteries are healthy.
