Description
From both vCenter Server and vSphere
Client. A vSwitch is a virtualized version
of a Layer 2 physical switch. A vSwitch
can route traffic internally between virtual
machines and link to external networks.
You can use vSwitches to combine the
bandwidth of multiple network adapters
and balance communications traffic among
them. You can also configure a vSwitch to
handle a physical NIC failover.
Description
To monitor operating system failures,
VM-Level High Availability monitors
heartbeat information in the VMware High
Availability cluster. Failures are detected
when no heartbeat is received from a given
virtual machine within a user-specified time
interval. VM-Level High Availability is
enabled by creating a resource pool of VMs
using VMware vCenter Server.
To monitor physical servers, an agent on
each server maintains a heartbeat with the
other servers in the resource pool such that
a loss of heartbeat automatically initiates
the restart of all affected virtual machines
on other servers in the resource pool.
Host-Level High Availability is enabled by
creating a resource pool of servers or hosts,
and enabling high availability in vSphere.
