Additional requirements depend on several factors such as:
Hard disk capacity – the requirements of the operating system and applications running on a target device. Citrix
recommends adding 20% to the base size of the final installed image.
Private Image Mode – the number of target devices using a vDisk in Private Image mode (vDisks in Private Image mode
should be backed up daily).
Standard Image Mode – the number of target devices using a vDisk in Standard Image mode. Best practice is to include
making a copy of every vDisk created.
Minimum common storage sizes
250 MB for the database
5 GB on a clean Windows system
15 GB per vDisk for Vista Class images (estimated)
Network adapter
Static IP
Minimum 100 MB Ethernet, 1 GB Ethernet preferred; Dual 1 GB Ethernet for more than 250 target devices. Two NICs
often perform better than a single dual-ported NIC.
Provisioning Server software
The Provisioning Server install program requires Microsoft NET 4.5.2 and Windows PowerShell 3.0
Network requirements
UDP and TCP port requirements
Provisioning Server to Provisioning Server communication
Each Provisioning Server must be configured to use the same ports (UDP) in order to communicate with each other using
the Messaging Manager. At least five ports must exist in the port range selected. The port range is configured on the
Stream Services dialog when the Configuration wizard is run.
Note: If you are configuring for high availability (HA), all Provisioning Servers selected as failover servers must reside within
the same site. HA is not intended to cross between sites.
The first port in the default range is UDP 6890 and the last port is 6909.
Provisioning Servers to target device communication
Each Provisioning Server must be configured to use the same ports (UDP) in order to communicate with target devices
using the StreamProcess.
The port range is configured using the Console’s Network tab on the Server Properties dialog.
The default ports include: UDP 6910, 6911, 6912, 6913, 6914, 6915, 6916, 6917, 6918, 6919, 6920, 6921, 6922, 6923, 6924,
6925, 6926, 6927, 6928, 6929 and 6930. However, the first 3 ports (6910, 6911, 6912) are reserved for Provisioning
Services.
Target device to Provisioning Services communication
Target devices communicate with Provisioning Services using UDP 6901, 6902, 6905 ports. Unlike Provisioning Servers to
target device port numbers, target device to Provisioning Services communication cannot be configured.
Login server communication
Each Provisioning Server used as a login server must be configured on the Stream Servers Boot List dialog when the
