The Lenovo ThinkSystem DE line of storage systems provide entry level block storage in a variety of hybrid or all flash models. The ThinkSystem DE series replaces Lenovo’s V3700 entry level systems.
ThinkSystem DE systems feature an active-active dual controller design in a 2U or 4U chassis depending on the model. The DE system consists of the DE4000F and DE6000F all flash models, as well as the DE2000H, DE4000H, and DE6000H hybrid models.
The entry level Lenovo systems offer up to 2.94 PB of raw capacity in the all flash models and up 5.76 PB in the hybrid models. The systems can scale up with the addition of up to seven expansion shelves (3 for the DE200H). The DE models support 16 and 32 Gb/s Fibre Channel and 10 and 25 GigE iSCSI host connectivity.
The ThinkSystem DE series offer a number of features that are desirable in a block storage system including snapshots, synchronous and asynchronous mirroring, and data at rest encryption. Lenovo also utilizes their Dynamic Drive Pools technology for data protection and simplification of RAID management. DE systems utilize Lenovo’s XClarity Administrator for resource management through a web-based interface.
For the top level all flash model, the DE6000F, Lenovo has claimed performance metrics of up to 1 million IOPS and 21 GB/s read throughput. For the DE4000H model, Lenovo has reported 300K IOPS and 10 GB/s read throughput.
