a cooling distribution unit CDU (tower). See Figure 4-4 on page 54 for an example E-Cell
configuration with single CDU.
E-Cell Functional Overview
An E-Cell consists of two E-racks and a dedicated cooling rack and also a special cooling
distribution rack (CDU). The separate CDU supplies water that dissipates heat off the system
CPUs, optional graphics accelerator cards and any other liquid-cooled components.
E-Cell Compute Rack Specifications
E-Cell configuration size and weight differences are noted in Table 4-2. In each E-cell compute
rack there are four shelves for 9-slot blade enclosures. Note that the left and right-side compute
racks are internally different because of air-flow requirements.
