Programmers have adapted them to run with the vmkernel: VMware Inc has changed the module-loading and some other minor things. Both of these Console Operating System functions are being deprecated from version 5. This is colloquially known as a purple diagnostic screen, or purple screen of death PSoD, cf. Upon displaying a purple diagnostic screen, the vmkernel writes debug information to the core dump partition. This information, together with the error codes displayed on the purple diagnostic screen can be used by VMware support to determine the cause of the problem.
This version of vCenter Server is limited in some features when compared to other versions although it still provides the basic management necessary for smaller vSphere environments. It is sold as a separate license and only supports managing up to four vSphere ESXi hosts. This is true for vSphere starting with vSphere 6. This version of vCenter Server is best suited for environments where there will be no more than four vSphere ESXi hosts to manage and no requirement of some of the business continuity features.
