    Chapter 1. Storwize V7000 Unified hardware components A Storwize V7000 Unified system consists of one or more machine type 2076 rack-mounted enclosures and two machine type 2073 rack-mounted file modules. There are several model types for the 2076 machine type. The main differences among the model types are the following items: v The number of drives that an enclosure can hold.
