Executive summary The purpose of this document is to assist customers with planning the architecture of the HP Device Manager (HPDM) components and configuring those components for the number of devices that will be managed. This document focuses on managing larger thin client deployments using HPDM. This document also includes tips to fine-tune the performance of HPDM. Hardware recommendations The HP Device Manager User Guide and Release Notes provide the minimum requirements for server hardware.

Deployment recommendations Topology The following diagrams show the topology of both a typical and an advanced HPDM deployment. Figure 1. Topology of typical HPDM deployment Figure 2.
PAGE 4
Deployment factors • Total number of managed thin clients – Use more powerful, server-level hardware configuration; for example, RAID. – 20,000 is the recommended maximum number in one HPDM system. Lab testing shows that HPDM performs most efficiently up to this number. – Current customers successfully use HPDM to manage up to 50,000 devices with a single server with these considerations: • Use of networks faster than 1000 MB.
PAGE 5
4000 MB ÷ 3.5 MBps ÷ 60 sec per min ≈ 20 minutes to transfer the image file The actual imaging task takes longer because there are extra steps before and after the file transfer. However, you can start another batch without influencing the previous batch because the extra steps do not need much bandwidth. In this example, the recommended value would be 30 units per batch and 30 minutes between batches because leaving a buffer is recommended.
PAGE 6
Configurations HPDM manages devices remotely with tasks. Configuring the most suitable parameters for tasks can help improve performance. Batch tasks There are three kinds of tasks: PXE, FTP, and General. PXE tasks are PXE imaging tasks. FTP tasks are tasks that use file transmission, except for PXE tasks. All other tasks are general tasks. The PXE server and file repositories are bottlenecks for simultaneous task executions.

Figure 5. Setting default batch amount and interval values Agent settings There are two parameters in the HPDM Agent settings that affect HPDM performance: Delay Scope The HPDM Agent sends a startup report at a randomly chosen time between 0 and the “Delay Scope” after it is started.
PAGE 8
Figure 6. Setting the Delay Scope and Pull Interval on the HPDM Agent Task automation You can define rules so that the HPDM Server can send tasks to the proper devices automatically. Well-defined rules can reduce not only network traffic from the HPDM Console to the HPDM Server, but also concurrent task reports. Using rules There are three kinds of rules designated by their triggers: Scheduled, First Contact, and Startup. Use a Scheduled Rule to reduce the traffic from the HPDM Console to the HPDM Server.
PAGE 9
Backup and restore Use the HPDM Server Backup and Restore Tool to backup database and HPDM Server files. You can run this backup tool periodically, such as once a month. See the HP Device Manager User Guide for detailed steps. Use cases HPDM is used by thousands of customers throughout the world in deployments ranging in size from 30 units to 50,000 units. HPDM is modular to allow customers to structure HPDM to fit into their existing corporate network architecture.
