In the earlier articles, the core concepts of the network were reviewed in the virtual infrastructure of the VMware platform. Now it's time to talk about VMware ESXi Dump Collector Support considering the concepts we've learned before.
VMware ESXi Dump Collector Support
First, let's get a return to the dry and useless courses of the university! Certainly, at that time, you have read the Core Dump word for the operating system. Core Dump is a snapshot of memory. The significance of this concept is so great that it has many uses in criminology and security issues, and it's actually because of the possibility of extracting Core Dump, which should not turn off computer crime scenes.
In VMware, there's also Core Dump types like any other Enterprise platform. For example, one of the most important Core Dumps of ESXi is the VMkernel Memory memory transcription. Every time the ESXi host encounters a critical failure or error, a memory copy of the VMkernel occurs at the time of the incident. VMware ESXi Dump Collector is referred to the unit that is doing this.
ESXi Dump Collector supports ESXi 5.1 and later both standard and Distributed switches. If the IP address of the VMkernel adapter is changed, this change also occurs in the ESXi Dump Collector interface. This automatic update applies to the change of Gateway.
If you want to delete the VMkernel Network Adapter used by the ESXi Dump Collector, this operation will stop by displaying a Warning. To do this, you must first disable Dump Collection and then attempt to remove the Network Adapter.
It's better to know that there is no authentication and encryption in the Session file transfer between hosts and ESXi Dump Collector does not exist. For this reason, it is recommended that the ESXi Dump Collector be installed in a separate VLAN from the main network.
