‘VMware View 4.6 Released’ Well really, it’s only about the View Security Server

VMware announced the general availability of VMware View 4.6, which is about finally making the View Security Server compatible with PCoIP!

VMware View 4.6 has been just released and as everyone expected this release introduces support for external secure remote access with PCoIP, without requirement for a SSL VPN.  There are more new features but they are ‘small’. Read the full list here:  Anyway, prior to View 4.6 if VMware decided to utilize the existing Security Server SSL PCoIP packets would end-up getting acknowledged at the bottom SSL TCP layer. This acknowledgement would defeat the purpose and nature of UDP transmission which is better datagram flow and ability to handle packet loss. Common network applications that use UDP include: the Domain Name System (DNS), streaming media applications such as IPTV and Voice over IP (VoIP).

It is still possible and there is nothing to prevent the use of an SSL VPN over TCP 443. However, verify that your VPN solution is capable of creating UDP tunnels that would provide better performance for PCoIP than TCP based VPN.

VMware View 4.6 support PCoIP tunneling on Security Servers and Connection Servers. It is also possible to proxy PCoIP through Connection Servers. The architecture is rather simple, however in order to utilize the PSG (PCoIP Software Gateway) it is required to upgrade existing Security Servers to Windows 2008 R2. If the Connection Server must work as PCoIP proxy it is required to upgrade them to Windows 2008 R2. Each PCoIP Gateway will support a validated maximum of 1,000 simultaneous connections.It is possible to pair a security server that runs on a Windows 2008 R2 host with a Connection Server instance that runs on Windows Server 2003 or 2003 R2 without affecting PCoIP Gateway functionality.

  1. PCoIP is certainly a great display protocol, and the new security server will definitely extend VMware View’s reach for remote users. However in some scenarios of high latency/low bandwidth remote connections (like over certain WANs), you may need to complement the VMware View deployment with Ericom Blaze, a software-based RDP acceleration and compression product that provides improved performance over WANs and other slow networks. Besides delivering higher frame rates and reducing screen freezes and choppiness, Blaze accelerates RDP performance by up to 25 times, while significantly reducing network bandwidth consumption especially over low-bandwidth/high latency connections.

    You can use VMware View with PCoIP for your LAN and fast WAN users, and at the same time use VMware View with Blaze over RDP for your slow WAN users. This combined solution can provide enhanced performance in both types of environments.
