5.8.4 PowerVM NovaLink and Hardware Management Consoles 5.9 Power Enterprise Pools Although PowerVM NovaLink provides functions that are similar to an HMC in terms of LPAR  management and managing your PowerVM environment, they complement each other where  an environment that has them co-manage it provides the benefits of both. Unlike an HMC,  PowerVM NovaLink servers are not appliances.  Table 5-1 shows how the capabilities of NovaLink and HMCs differ, but it also shows how they  complement each other. By using both in co-management mode, you can modernize your  AIX infrastructure with the capabilities that are offered by PowerVM NovaLink while  maintaining the hardware management abilities that are offered by HMCs. To run in  co-management mode, you need HMC V8.4.0 Service Pack 1 or later. This section introduces the concepts, features, and benefits of Power Enterprise Pools (PEP),  a technology that shares processor cores and memory among a pool of Power Systems  servers. PEP is the natural response to an increased demand for flexibility and  responsiveness.  PEPs are available in two editions: This section briefly introduces the components and benefits for both editions. Chapter 5.
