Technical white paper | HP Hardware Accelerated Graphics for Desktop Virtualization Appendix B-Alternative remoting protocols and brokers The following section covers only alternative options for remoting protocols and brokers that we have seen successfully used. The fact that these options are discussed here does not mean that they fully supported by the different platforms. Leostream-Connection Broker A connection broker manages the assignment and connection of end users to their virtual machines. Individual virtualization partners provide integrated connection brokers as part of their virtualization stack. In some cases, however, a third party connection broker becomes necessary to provide the flexibility and functionality required to support more complicated end-user environments. The Leostream Connection Broker is a vendor-independent connection broker that allows you to manage a mixed environment that includes Citrix XenServer, Microsoft Hyper-V, VMware vSphere, and Graphics Server Blades in a single Administrator Web interface, and simultaneously connect users to a mixed environment from a single login screen. Leostream integrates with your existing infrastructure, including authentication servers, load balancers, and SSL VPNs, and supports all major display protocols, including Citrix HDX, Microsoft RemoteFX, and HP RGS. Leostream Connection Broker policies allow you to control which resources the user is offered, how long they can use the resources, and what type of end-user experience they received, based on the user's identity and also on their location. The Leostream high availability features, such as backup pools, Connection Broker clustering, and database mirror-awareness, ensure that users remain productive in the event of failure as minor as a single blade to as large as an entire data center. You may want to investigate Leostream if your environment fits into any of the following categories. • It includes Linux remote desktops as well as Windows desktops • You have different user groups who use RGS, HDX, RemoteFX, RDP, or other display protocols • You have authentication servers other than Active Directory, such as eDirectory, OpenLDAP, or NIS • You have a multi-domain environment with untrusted domains • You have complicated use case requirements that change as the user's location changes The Connection Broker is a virtual appliance that can be imported into a VMware, Citrix, or Microsoft virtualization layer. The Connection Broker requires virtual resources equivalent to the following hardware: • 1500 MHz or faster Intel® Pentium® IV processor (or equivalent) • 1 vCPU • 2.0 GB of RAM • 8 GB of hard drive space • Bridged Ethernet adapter, ideally with Internet connectivity Adding a second CPU to the virtual appliance does not improve Connection Broker performance as the appliance does not take advantage of the new CPU. To improve Connection Broker performance, build a Connection Broker cluster. A Connection Broker cluster is a group of Connection Brokers that share the same Microsoft SQL Server database. A common cluster uses three to five Connection Brokers. For more information-leostream.com 31
