Load Balancing Session Placement Examples
These examples illustrate two load balancing session placement scenarios.
Example 1: No Existing User Session
This example illustrates how session placement might occur for a farm that contains six RDS hosts when a
user session does not currently exist on any of the RDS hosts.
1 Horizon Agent reports the following load preferences for each RDS host in the farm.
RDS Host Load Preference
1 HIGH
2 LOW
3 HIGH
4 MED
5 BLOCK
6 LOW
2 View sorts the RDS hosts into three buckets according to load preference. View discards RDS host 5
because Horizon Agent reported a load preference of BLOCK.
Bucket Load Preference RDS Host
1 HIGH
HIGH

3 LOW

3 Because bucket 2 has only one RDS host, View combines bucket 2 and bucket 3
