What is VMKernel and why it is important

hi experts

is this the correct answer

VMkernel is a virtualization interface between a Virtual Machine and the ESXi host which stores VMs. It is responsible to allocate all available resources of ESXi host to VMs such as memory, CPU, storage etc.

or this

The VMkernel networking layer provides connectivity to hosts and handles the standard system traffic of vSphere vMotion, IP storage, Fault Tolerance, vSAN, and others. You can also create VMkernel adapters on the source and target vSphere Replication hosts to isolate the replication data traffic.

You can see an example of it's use here, in this article I wrote about iSCSI Storage

The VMKernel TCP/IP stack Portgroup handles traffic for the following ESXi services iSCSI, NFS, VMware vMotion and host management. To create a multipath iSCSI network at least two VMKernel TCP/IP stack Portgroups needed to be created on a virtual switch.
