Executive summary Important: This document describes a performance characterization performed utilizing the HP 64-bit test harness, which incorporates a Microsoft® Office 2003 workload. Test results cannot be compared directly with the results of tests performed using the 32-bit Office XP- or Office 2003-based harness. 1 The HP ProLiant DL585 G5 is a highly manageable, rack-optimized, four-socket server designed for maximum performance in an industry-standard architecture. With up to

Introduction The HP ProLiant DL585 G5 server (shown in Figure 1) is ideal for multi-threaded, multi-tasked environments, high-performance computing, and HP SBC. Figure 1. HP ProLiant DL585 G5 server AMD Opteron processors The HP ProLiant DL585 G5 server supports up to four Quad-Core AMD Opteron 8300 Series processors. This native quad-core processor delivers the following benefits: • Outstanding performance The Quad-Core AMD Opteron processor is designed for optimal multi-thr

AMD Dual Dynamic Power Management Without compromising performance, AMD Dual Dynamic Power Management functionality allows each processor to maximize the power-saving benefits of Enhanced AMD PowerNow! by reducing idle power consumption and enabling per-processor power management in multi-socket systems to further reduce power consumption. By powering core and memory controller voltage planes independently, AMD Dual Dynamic Power Management can enhance both performance and power managemen

This section provides more information on test tools, user profiles and test scenarios. Test tools To facilitate the placement and management of simulated loads on an HP SBC server, HP used Terminal Services Scalability Planning Tools (TSScaling), a suite of tools developed by Microsoft to help organizations with Microsoft Windows® Server 2003 Terminal Server capacity planning. Table 1 describes these tools. Table 1. Components of TSScaling Component Description Automation tools Robosr

User profiles To simulate typical workloads in this environment, HP used scripts based on the Heavy, Medium, and Light User profiles described in Table 2. Table 2. User profiles incorporated into the test scripts User class Activities Heavy User Heavy Users (also known as Structured Task Workers) tend to open multiple applications simultaneously and remain active for long periods. Heavy Users often leave applications open when not in use. Medium User Medium Users (also known as Knowledg

Test scenarios For the Heavy User type, HP initiated testing by running the appropriate script with a group of 15 simulated users. Start times were staggered to eliminate authentication overhead. After these sessions finished, HP added 15 more users, then repeated the testing. Further groups of 15 users were added until the maximum number of users was reached. For Medium and Light User types, HP utilized groups of ten users. Performance and scalability metrics While the scripts were runni

Canary times Figure 4 shows sample results for the HP ProLiant DL585 G5 server running a typical canary script. Individual user response times are shown in blue, with a yellow line depicting average response times. HP analyzed this figure to determine when response times began to increase markedly and consistently over a baseline level, indicating that user response times had become unacceptable. Figure 4.

Test analysis summary Figure 5 summarizes the optimal numbers of users supported by the HP ProLiant DL585 G5 server. Figure 5. Optimal numbers of users supported in the 64-bit test harness HP characterized the scalability of the HP ProLiant DL585 G5 server through the numbers of users supported when CPU utilization reached 80%. Recommendations Since x64 platforms allow you to better utilize memory and multi-core processors, the bottleneck you 6 are most likely to encounter is ass

Note: In the event of an I/O bottleneck, you should tune the disk subsystem, decrease the number of users or applications, or add memory to the server. Using BBWC HP Smart Array controllers include an allocation of RAM that can be utilized to temporarily buffer data being written to or read from disk. Since access to this RAM is significantly faster than disk access, cache can enhance overall server performance, particularly during login operations. Write cache is of particular interest

Appendix B – SBC solution sizing As with any laboratory benchmark, the performance metrics quoted in this performance brief are idealized. In a production environment, these metrics may be impacted by a variety of factors, including the following: • Overhead Agents and services (virus scanning, backup and restore, provisioning, security, management and more) automatically consume overhead. Rogue applications can consume additional overhead. The system architect may wish to provide a 25%
