6.13.1 Hardware topology Figure 6-44 shows the initial status of the hardware topology. Figure 6-44 Initial status of the hardware topology 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. 250  IBM PowerHA SystemMirror V7.2.3 for IBM AIX and V7.2.2 for Linux
