Using Boot Device Manager utility on PVS Server, bootstrap file can be written into a local hard drive.īDM ISO option will use a Two stage bootstrap process and hence the TFTP services will be needed to download the second half of the bootstrap file. Yes, by using Boot Device Manager (BDM) both PXE and TFTP can be eliminated from communication process. Is there a way to eliminate both PXE Service and TFTP from communication process? Client VMs will directly contact TFTP server and download the bootstrap program. Yes, by specifying TFTP Server IP Address and bootstrap file name in DHCP Scope options 66 and 67 on DHCP Server. DHCP server provides TFTP details to the clients along with dynamic IP address. Is there a way to eliminate PXE Service from the communication process? Just to summarize, PXE is used for getting the TFTP Server IP and bootstrap file name details by the clients and TFTP is used for downloading bootstrap program file. ![]() Target device starts streaming the vDisk from the PVS server.The logon server will notify the target device about the streaming server.The target device will contact and log onto one of the PVS servers.Next the bootstrap file will be downloaded and the target device will be boot from it.The target device first identifies a TFTP server.First the target devices boots and acquires an IP address.If there is an associated target device available under the PVS environment, it’s boot setting values are read and the target device is booted according to these settings.Target device MAC address lookup completed.Target device communicates to the provided PVS Server and its associated running “Citrix PVS Stream Service”.The bootstrap file typically houses connectivity information for all of the PVS servers under your associated PVS Farm.TFTP services reads associated bootstrap, boot file (ARDBP32.BIN) information to provide back to the client as a usable network boot server. ![]() Target device connects to the TFTP server (typically a PVS Server) provided by DHCP services or by PXE Service.Target Device Connectivity to Provided TFTP Server.The PXE Service on the PVS Server will provide the location\IP Address of the server that hosts the ARDBP32.bin file, which is typically the PVS Server itself If the DHCP Option 66 and 67 is not configured, then we need to Setup\Configure the PXE service on the PVS Server.Very common to use default file name, rarely changed from default name.Under a PVS environment, the default file name is ARDBP32.BIN.If needed, and on rare occasion, TFTP services can also be hosted on an isolated/dedicated infrastructure server. ![]()
