Figure 6-44 shows the initial status of the hardware topology. 

<img src='content_image/996606.jpg'>

The topology includes the following components: 

GLYPH<SM590000> Two Power 780 D model servers, which are named P780D_09 and P780D_10. 

GLYPH<SM590000> One Power Enterprise Pool, which has 64 mobile processors and 2 TB of mobile memory resources. 

GLYPH<SM590000> There are 64 CPUs and 2 TB of memory that are installed in P780D_09, There are 32 CPUs, 1 TB of memory that is configured, and another 32 CPUs and 1 TB of memory are in the inactive status. Currently, there are five CPUs and 10 GB of memory available for the DLPAR. 

GLYPH<SM590000> The PowerHA SystemMirror cluster includes two nodes: 

– P780_09_Lpar1 

– P780_10_Lpar2 

GLYPH<SM590000> The PowerHA SystemMirror cluster includes one RG (RG2); this RG has one application controller (app2) with configured hardware resource provisioning. 

GLYPH<SM590000> This application needs 20 C and 40 G when it runs. 

GLYPH<SM590000> There is no On/Off CoD in this testing. 

GLYPH<SM590000> There are two HMCs to manage the EPCoD, which are named HMCEP1 and HMCEP2. HMCEP1 is the master and HMCEP2 is the backup, as shown in Example 6-31.
