Executive summary Important: This document describes a perfor mance characterization performed utilizing the HP 64-bit test harness, which incorporates a Microsoft® Office 2003 workload. Test results cannot be compared directly wit h the results of tests performed using the 32-bit Office XP- or Office 2003-based h arness. The HP ProLiant DL585 G5 [...]

Introduction The HP ProLiant DL585 G5 serv er (shown in Figure 1) is ideal for multi-threaded, multi-ta sked environments, high-perform ance computing, and HP SBC. Figure 1 . HP ProLiant DL585 G5 server AMD Opteron processors The HP ProLiant DL585 G5 serv er supports up to four Quad-Core A MD Opteron 8300 Series processors. This native quad-core pr[...]

AMD Dual Dynamic Power Management Without compromising performanc e, AMD Dual Dynamic Power Mana gement functionality allows each processor to maximize the power-saving benefits of Enhanc ed AMD PowerNow! by reducing idle power consumption and enabling per-processor power management in multi-socket systems to further reduce power consumption. By po[...]

This section provides more information on test tools, user profil es 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 (TSSca ling), a suite of tools developed by Microsoft to help organizations with Microsoft Windows® Se rver 2003 [...]

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 Wo rkers) tend to open multiple applications simultaneously [...]

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 elim inate authentication over head. After thes e sessions finished, HP added 15 more users, then repeated the testing. Further groups of 15 users were added until the maximum number of use[...]

Perfmon values HP ran a series of performance tests u sing scri pts based on the Heavy, Medium, and Light User profiles. Figure 3 shows the test res ults for Heavy Users. Figure 3 . % Processor Time values for Heavy Users – showing that 288 Heavy Us ers were supported when processor utilization reached 80% Figure 3 shows the optimal number of H e[...]

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 re sponse times began to increase markedly and consistently over a baseline level, indicatin[...]

Test analysis summary Figure 5 summarizes the optimal numbers of user s supported by the HP ProLiant DL585 G5 server. Figure 5 . Optimal numbers of user s supported in the 64-bit test harness HP characterized the scalability of the HP ProLia nt DL585 G5 server through the number s of users supported when CPU ut ilization reach ed 80%. Recommendatio[...]

Note: In the event of an I/O bottleneck, you should tune t he disk subsystem, decrease the number of users or applic ations, or add memory to the server. Using BBWC HP Smart Array controllers include an allocation o f RAM that can be utilized to temporarily buffer data being written to or read from disk. Since access to thi s RAM is sig nific antly[...]

Appendix A – Using Microsoft Windows Server 2003 x64 Editions Microsoft offers high-performance platforms for 64 -bit applications with continued support for 32-bit applications and existing deployment and manage ment tools – all on the same platform. These operating systems provide an ev olutionary path to 64-bit techno logy, allowing 64-bit a[...]

Appendix B – SBC solution sizing As with any laboratory benchmark, the performanc e metrics quoted in this performance brief are idealized. In a production environment, these me trics may be impacted by a variety of factors, including the following: • Overhead Agents and services (virus sca nning, backup and restore, provisio ning, security, ma[...]
