PCoIP Management Console User Manual
1.3.2
Fixed Seating
The MC allows an administrator to link individual Host and Zero Client devices so that
each Zero Client always establishes a connection to the same Host. This relationship is
called
fixed seating
. If a PCoIP deployment requires the ability to dynamically assign
Hosts to Zero Clients when users login the administrator must install a connection broker.
The MC does not support dynamically assigning Hosts to Zero Clients.
1.3.3
Device Discovery
All PCoIP devices managed by the MC must be discovered by the MC. The MC supports
discovering devices in a deployment using one or more discovery mechanisms.
1. It is recommended to install a MC DNS SRV record. Section 1.3.3.1 describes how to
install a DNS SRV record.
Note it may not be possible to install a DNS SRV record because the network does
not include a DNS server or multiple instances of the MC will be installed on the same
network managing subsets of the PCoIP devices.
2. If a DNS SRV record cannot be installed users may be able to configure the devices
to automatically notify the MC of their existence. PCoIP devices support a
configuration setting called the
PCoIP MC DNS-Based Discovery Prefix
. Section
1.3.3.2 describes how this feature works and the deployment requirements associated
with using this discovery method.
Note: The
PCoIP MC DNS-Based Discovery Prefix
setting can only be accessed
using the MC. It is not accessible through the device web interface or Zero Client OSD
interface.
3. If a DNS SRV record cannot be installed and the deployment cannot use the
PCoIP
MC DNS-Based Discovery Prefix
configuration setting then the final automated device
discovery option available is SLP discovery. This device discovery method imposes a
restriction that limits its usefulness. To use this feature all PCoIP devices and the MC
must reside on the same network subnet.
4. If a deployment cannot support any of the previous device discovery options then the
administrator can use the MC to configure devices. The MC supports a Manual
Discovery feature that allows the MC to find devices. This feature is described in
section 1.3.3.3. Below are some shortcomings associated with this approach:
•
If a device has enabled DHCP, the MC will lose contact with a device if its IP
address changes. The administrator would need to perform another manual
discovery search to find devices that were assigned new IP addresses.
1.3.3.1 DNS Service Record Discovery
When DNS SRV record discovery is used, the PCoIP devices advertise themselves to
the MC. All devices that use the DNS server will be able to find the MC. If DNS-SRV
discovery is not enabled, the MC must seek out and find devices using methods that are
often subject to limitations, such as being unable to search more than its local subnet.
The system requirements for DNS SRV discovery are as follows:
•
The deployment must have a DNS Server in the network
•
Two DNS records must be installed on the DNS server
o
An A record (name record) for the MC
o
A SRV record (service record) created following the steps below
