Chapter 2. System overview 13
An IBM Storwize V7000 solution provides a choice of up to 760 disk drives per system or 
1024 disk drives per clustered system (by using dense drawers). The solution uses SAS 
cables and connectors to attach to the optional expansion enclosures.
The IBM Storwize V7000 system supports a range of external disk systems similar to what 
IBM SAN Volume Controller supports today. A view of an IBM Storwize V7000 control 
enclosure is shown in Figure 2-4.

The IBM Storwize V7000 solution consists of 1 - 4 control enclosures and optionally, up to 36 
expansion enclosures. It supports the intermixing of the different expansion enclosures. Each 
enclosure contains two canisters. Control enclosures contain two node canisters, and 
expansion enclosures contain two expansion canisters.
2.3.1  IBM Storwize V7000 models
The IBM Storwize V7000 consists of enclosures and drives. An enclosure contains two 
canisters that are seen as part of the enclosure, although they can be replaced 
independently.
The IBM Storwize V7000 models are listed in Table 2-1.
