Overview The purpose of this document is to assist customers who are planning the architecture of HP Device Manager (HPDM) components and configuring those components for the number of devices that will be managed. This document focuses on managing larger device deployments using HPDM. This document also includes tips to fine-tune the performance of HPDM.

Port usage Figure 2. Port usage in HPDM Console TCP: 1099 TCP: 40012 Master Repository TCP: 40002 Server TCP: 40006 PostgreSQL TCP: 40005 TCP: 40003 TCP: 40008 Gateway Controller Gateway TCP: 50000 PCoIP Zero Client TCP: 40003 TCP: 40001 Agent Server/Agent Poll UDP: 40000 Gateway Console/VNC Proxy Reverse Shadow TCP: 40004 Agent Resource Monitor TCP: 40009 Server Shadow TCP: 40004 Agent/VNC Proxy Note This chart lists only the basic ports created by HPDM.

Hardware enviroment The following table provides the minimum hardware requirements of HPDM components. Table 1.
PAGE 5
Disk space usage of the database The disk space usage of the database grows with the device and task amounts. Calculate the required disk space with the following pattern: • The initial disk space is less than 50 MB. • Add an additional 100 MB for every 1,000 devices. • Add an additional 1 MB for every 100 tasks. Disk space usage of the repository The disk space usage of the repositories grows with the payload amount, especially with images of a device operating system.
PAGE 6
Number of devices As the total number of managed devices increases, use more powerful, server-level hardware configurations such as RAID. 50,000 is the recommended maximum number of devices in one HPDM deployment. Lab testing shows that HPDM performs most efficiently up to this number.
PAGE 7
20,000 GB ÷ (100 Mbps ÷ 8 bits per byte ÷ 1000 x 3600 seconds per hour) ≈ 444.4 hours To reduce the data transfer time to 48 hours, you need 10 repositories (444.4 ÷ 48). Keep in mind that there is some overhead to synchronize from the Master Repository to the Child Repositories. Simultaneously connected users There is no significant increase of memory or CPU usage on the HPDM Server for any additional, connected HPDM Consoles. However, it requires more resources for database access and communication.
PAGE 8
Normal scale deployment Device number: 25,000 Deployment: 1 HPDM Server, MS SQL Server, 3 HPDM Gateways, 1 Master Repository, 2 Child Repositories. Figure 4.
PAGE 9
Huge scale deployments Device number: >50,000 Deployment: Because one HPDM Server supports up to 50,000 devices with verified performance, deployments of greater than 50,000 devices require multiple instances of HPDM. You mighte view it as multiple Normal scale deployments to deploy. Optimizing HPDM configurations HPDM manages devices remotely with tasks. Configuring the most suitable parameters for tasks can help improve performance.
PAGE 10
To calculate the time it will take: 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 HP recommends leaving a buffer.
PAGE 11
You can also supersede the default settings by adjusting the batch settings for each task before sending it. Figure 7. Setting default batch amount and interval values HPDM Agent settings There are two parameters in the HPDM Agent settings that affect HPDM performance: • Delay Scope—After it is started, the HPDM Agent sends a startup report at a randomly chosen time between 0 and the chosen Delay Scope.
PAGE 12
Using rules You can define rules so that the HPDM Server sends 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. There are three kinds of rules, designated by their triggers: Scheduled, First Contact, and Startup. Without rule tasks, finding devices that meet specific criteria and sending tasks to them can be a major part of the daily work of an administrator.

Appendix 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, which allows customers to structure HPDM to fit into their existing corporate network architecture. Like any tool, the components of HPDM can be optimally configured to make the best use of system and network performance. The use of multiple HPDM Servers is highly recommended to ensure fast testing, validation, and delivery in production environments.
