VMware Blast Policy Settings
The VMware Blast group policy template file vdm_blast.adm contains policy settings for the VMware Blast
display protocol. After the policy is applied, the settings are stored in the registry key
HKLM\Software\Policies\VMware, Inc.\VMware Blast\config.
These settings apply to HTML Access and all Horizon Clients.
Table 17‑11. VMware Blast Policy Settings
Setting Description
Max Session
Bandwidth
Specifies the maximum bandwidth, in kilobits per second (kbps), for a VMware Blast session.
The bandwidth includes all imaging, audio, virtual channel, USB, and VMware Blast control
traffic. The default is 1 Gbps.
Min Session
Bandwidth
Specifies the minimum bandwidth, in kilobits per second (kbps), that is reserved for a
VMware Blast session. The default is 128 kbps.
Max Frame Rate
Specifies the maximum rate of screen updates. Use this setting to manage the average
bandwidth that users consume. The default is 30 updates per second.
UDP Protocol
Specifies whether to use the UDP or the TCP protocol. The default is not to use the UDP
protocol, that is, to use the TCP protocol. Enable this setting to use the UDP protocol. This
setting does not apply to HTML Access, which always uses the TCP protocol.
H264
Specifies whether to use H.264 encoding or JPEG/PNG encoding. The default is to use H.264
encoding.
Screen Blanking
Specifies whether to have the desktop VM's console show the actual desktop that the user
sees or to show a blank screen when the desktop has an active session. The default is to show
a blank screen.
Session Garbage
Collection
Specifies how garbage collection of abandoned remoting sessions runs. You specify two
values:
n
Interval (ms) determines how often, in milliseconds, the garbage collector runs. The
default is 100 ms.
n
Threshold (s) determines how old, in seconds, an abandoned session must be before it is
a candidate for deletion. The default is 1 second.
Image Quality
Specifies the image quality of the desktop display. You can specify two low-quality settings,
two high-quality settings, and a mid-quality setting. The low-quality settings are for areas of
the screen that change often, for example, when scrolling occurs. The high-quality settings are
for areas of the screen that are more static, resulting in a better image quality. You can specify
the following settings:
n
Low JPEG Quality (available range of values: 1 - 100, default: 25)
n
Low JPEG Chroma Subsampling (available range of values: 4:1:0 (lowest), 4:1:1, 4:2:0,
4:2:2, and 4:4:4 (highest), default: 4:1:0)
n
Mid JPEG Quality (available range of values: 1 - 100, default: 35)
n
High JPEG Quality (available range of values: 1 - 100, default: 90)
n
High JPEG Chroma Subsampling (available range of values: 4:1:0 (lowest), 4:1:1, 4:2:0,
4:2:2, and 4:4:4 (highest), default: 4:4:4)
HTTP Service
Specifies the port that is used for secure communication (HTTPS) between the security server
or Access Point appliance and a desktop. The firewall must be configured to have this port
open. The default is 22443.
