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. Drives are located on the front
v Whether the model is a control enclosure or an expansion enclosure.
v If the control enclosure has either 1 Gbps Ethernet capability or 10 Gbps
The machine type and model for the file module is 2073-720.

of the enclosure. An enclosure can hold up to 12 3.5-inch drives or up to 24
2.5-inch drives.
Control enclosures contain the main processing units that control the whole
system. They are where external systems, such as host application servers, other
storage systems, and management workstations are connected through the
Ethernet ports or Fibre Channel ports. Control enclosures can also be connected
to expansion enclosures through the serial-attached SCSI (SAS) ports.
Expansion enclosures contain additional storage capacity. Expansion enclosures
connect either to control enclosures or to other expansion enclosures through the
SAS ports.
