In-Depth Information
Swap File Location
This area is where you will coni gure the location of the swapi les
for running VMs on the host. By default, the swapi le is stored in the same directory as
the VM itself. When an ESXi host is in a cluster, the cluster setting overrides the per-host
coni guration.
Licensing
This command allows you to view the currently licensed features as well as to
assign or change the license for the selected ESXi host.
Host Proi le
While there is a Host Proi les area accessible from the Home screen, this area
lets you attach a host proi le as well. See the section “Working with Host Proi les” later in this
chapter.
Time Coni guration
From here, you can coni gure time synchronization via NTP for the
selected ESXi host. You saw this area within the vSphere Client in Chapter 2.
Authentication Services
We'll discuss this in more detail in Chapter 8, but this area allows
you to coni gure how ESXi hosts authenticate users.
Power Management
If you want to use Distributed Power Management (DPM), you'll need
to coni gure the ESXi hosts appropriately. This area is where that coni guration occurs.
Advanced System Settings
The Advanced System Settings area provides direct access to
detailed coni guration settings on the selected ESXi host. In the majority of instances, this is
not an area you'll visit on a regular basis, but it is helpful to know where it is in the event you
need to change a setting.
System Resource Allocation
The System Resource Allocation area allows you to i ne-tune
the resource allocation for the selected ESXi host.
Security Proi le
This area allows you to coni gure which daemons (services) should run on
the host.
System Swap
Within this section, you can disable or specify which datastore should be
used for host swapi les. We will explain host swapping and how it differs from VM swapping
in Chapter 11.
Processors
In this section, vCenter Server provides details about the processors in the
selected ESXi host as well as the ability to enable or disable hyperthreading on that ESXi host.
Memory
This area shows you the amount of memory installed in an ESXi; this only pro-
vides information about the memory in the host, how much is allocated to the system (ESXi),
and how much is allocated to VMs; there are no options to coni gure.
Graphics
Within the Graphics section, you can see what type of GPU is in the system and
how much memory it has. In Chapter 9 you can read about use cases for sharing the GPU of
an ESXi host to the guest VMs in certain circumstances.
Power Management
The Power Management area in the Hardware section differs from the
area under the System section above it. This section allows you to set various power-
management policies on the selected ESXi host.
vFlash Resource Management
Solid State Drive (SSD)-backed datastores can be allocated
to the vFlash resource type in this section. You can then further allocate this resource in the
Cache Coni guration below.
Cache Coni guration
This area allows you to specify or view the amount of space on Solid
State Drive (SSD)-backed datastores, or vFlash, that can be used for swapping. Swapping to
