This chapter provides a brief introduction to the ThinkSystem DE series products. ThinkSystem DE series are dedicated for high-bandwidth applications such as big data analytics, video-surveillance, and disk-based backup that need simple, fast, and reliable SAN storage.
A storage array includes shelves, controllers, drives, software, and firmware. The array can be installed in a rack or cabinet, with customizable hardware for two controllers, in a 12-, 24-, or 60-drive shelf. You can connect the storage array to a SAN from multiple interface types and to a variety of host operating systems. The ThinkSystem DE series storage arrays are available in several configurations and models. This guide provides installation and maintenance information for 2U* and 4U* models.
