Log Summary of ESXi host start-up and shutdown events, along with heartbeat information, virtual machine running information, and service resource consumption. Certainly we do not need to use all of these logs when it comes to troubleshooting storage. log files as these files contain the most crucial storage events that ESXi logs. Tip Most of the storage logging in ESXi is enabled by default; however, there are some things that are not. Log in the hosts advanced settings to see what is enabled and what is not.

Remote blocks are accessed by encapsulating SCSI commands and data into TCP/IP packets and transmitted over the Ethernet network. ESXi hosts access metadata and files located on the NFS server by utilizing file devices that are presented over a network.

Preface In 1998, a small company consisting of only five employees came out of stealth in Palo Alto, claiming to have successfully run Windows 95 on a virtual machine. This company was called VMware. 0 was released. 0. Since then, the type 1 hypervisor ESX, now only ESXi, has been a major driver in providing business agility in bringing services to their customers. When we think about many of the features that have been integrated into vSphere over the years, such as HA, vMotion, and Distributed Resource Scheduling; they all have shared one thing in common, storage requirements.
