Virtual network adapter VMXNET 3
IMPORTANT Horizon 6 version 6.1 and later releases do not support Windows XP and Windows Vista
desktops. View Agent 6.0.2 is the last View release that supports these guest operating systems. Customers
who have an extended support agreement with Microsoft for Windows XP and Vista, and an extended
support agreement with VMware for these guest operating systems, can deploy the View Agent 6.0.2
version of their Windows XP and Vista desktops with View Connection Server 6.1.
RDS Host Virtual Machine Configuration
Use RDS (Remote Desktop Services) hosts for providing hosted applications and session-based remote
desktops to end users.
An RDS host can be a physical machine or a virtual machine. This example uses a virtual machine with the
specifications listed in the following table. The ESXi host for this virtual machine can be part of a VMware
HA cluster to guard against physical server failures.
Table 43. RDS Host Virtual Machine Example
Item Example
Operating system 64-bit Windows Server 2008 R2 or Windows Server 2012 R2
RAM 24GB
Virtual CPU 4
System disk capacity 40GB
Virtual SCSI adapter type LSI Logic SAS (the default for Windows Server 2008)
Virtual network adapter VMXNET 3
1 NIC 1 Gigabit
Maximum number of client connections total
(including session-based remote desktop
connections and remote application connections)

vCenter Server and View Composer Virtual Machine Configuration
You can install vCenter Server and View Composer on the same virtual machine or on separate servers.
These servers require much more memory and processing power than a desktop virtual machine.
VMware tested having View Composer create and provision 2,000 desktops per pool using vSphere 5.1 or
later. VMware also tested having View Composer perform a recompose operation on 2,000 desktops at a
time. For these tests, vCenter Server and View Composer were installed on separate virtual machines.
Desktop pool size is limited by the following factors:
n
Each desktop pool can contain only one vSphere cluster.
n
With some setups, clusters can contain up to 32 hosts. With other setups, clusters are limited to 8 hosts.
For more information, see “vSphere Clusters,” on page 54.
