VMware View with PCoIP encryption and bandwidth metrics: Teradici recommendations for various clients (2009122)

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2009122

Purpose

This article specifies the Teradici-recommended encryption algorithm and bandwidth metrics for various setups of zero clients, soft clients, and soft and hard hosts for VMware View with PCoIP.

Resolution

For View 4.0.1:

• PCoIP Software client (VMware View) -------> VM default=AES128 (Salsa20 is preferred)
• Zero-client (VMware View) -------> VM default=AES128 (Salsa20 is preferred)

For View 4.5 and later:

• PCoIP Software client (VMware View) -------> VM default=Salsa20
• Zero-client (VMware View) -------> VM default=Salsa20
• PCoIP Software client (VMware View) -------> Hard-Host Card default=AES128 (Salsa20 is preferred)
• Zero-client (VMware View) -------> Hard-Host Card default=AES128 (supports speeds up to 220Mbps)

Salsa20 256-bit supports speeds up to ~20Mbps (see Note 1).

Note 1: Soft-client (VMware View) ------->Soft or Hard Host can exceed ~20Mbps regardless of encryption, although this depends on the performance of the client hardware.

Using Security Gateway View 4.6 and later:

• Zero-client -------> VMware View Security Gateway------->4.6 or later VM default=AES

Note: Must be AES128 on both ends.

• PCoIP Software client -------> VMware View Security Gateway------->4.6 or later VM default=AES

 Note: Must be AES128 on both ends.

•  Zero-client (VMware View) -------> VMware View Security Gateway------->Hard-Host Card default=AES128

AES 128-bit supports speeds up to ~7Mbps max due to the encryption required on the zero client to work with security gateway.

Salsa20 256-bit supports speeds up to ~20Mbps (see Note 1).

Note 1: Soft-client (VMware View) ------->Soft or Hard Host can exceed ~20Mbps regardless of encryption, although this depends on the performance of the client hardware. 

Using Hard PCoIP portal to connect to PCoIP host card:

• Zero-client ------> Hard-Host Card default=AES128
• AES128 in this configuration supports up to ~220Mbps throughput.
