SAM architecture The computing resources supported by SAM consist of blade workstations, blade PCs, the virtual desktop infrastructure, and client computers, as shown in Figure 2. Figure 2. The elements of the SAM architecture Computing (Can be a single computer) Blade Workstations SQL Server HP SAM Web Server Active Directory Client computer Blade PCs HPViSrteuravler Desktop Infrastructure RGS or RDP Client computer Client computer Client computer The HP SAM Web Server orchestrates connections between these computing resources and the client computers. When a user requests a connection to a computing resource, the HP SAM Web Server accesses the SQL Server database to determine how to allocate the requested computing resources to the user. The SQL database stores information such as: • The properties of each of the computing resources, including the roles that each computer is configured to provide. An example administrator-defined role is stock trader. Applications specific to this role are installed on computers that support this role. • The properties of each of the client computers, such as their monitor layout ID, which is associated with the number of attached monitors, their layout, and their resolutions. • The HP Remote Graphics Software (RGS) properties to use when making an RGS connection, such as windows borders on/off and the RGS image compression level. Based on this information, SAM allocates the remote computing resources required by each user. In doing this, the desktop session of one or more computing resources is displayed on the client computer. SAM uses RGS to connect client computers and blade workstations. As shown in Figure 3, RGS sends the desktop image from the blade workstation to the client computer. RGS also captures user
