## 5.8.4 PowerVM NovaLink and Hardware Management Consoles 

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.
